I don't know where it is, we don't allow farmers to drill seepage wells for sewage treatment, the reason is very simple, doing so will pollute the groundwater source, and even change the soil environment, causing water pollution.
Even if you don't think about others, you should think about yourself, and everyone has a responsibility to protect water resources.
What is the purpose of seepage wells? Maybe this was the case in the countryside in the past, in order to drain the sewage and rainwater at home, and then dig a deep well in the yard to discharge the sewage at home, which obviously will pollute the water resources, but the rural areas were sparsely populated in the past, and there were no toxic and harmful substances, and the impact was not so serious.
A few years ago, I saw people near the river digging a well in their own homes and discharging the outlet into the river, which means that their sewage was discharged into the river, but even this would pollute the river, and in recent years it has been completely removed.
Now the new countryside is also being transformed, especially the toilet renovation, sewage renovation, no longer the previous dirty mess, rural sewage has no outlet, often discharged on the side of the street, especially on rainy days, the road surface is always dirty, it can be said that it is a stubborn disease in the countryside.
Now the roads in the countryside have been built with cement roads, and the toilets at home are also modeled after the toilets in the city to build quite beautiful and hygienic, there will be a septic tank when repairing the toilet, but this is not a seepage well, one is very shallow, the other is all made of cement structure, and some are still plastic structures, which is also to prevent the discharged sewage from seeping into the ground and polluting our water resources.
Therefore, some people in rural areas have started to dig seepage wells at home, and this behavior should be stopped, after all, it will affect water resources and affect our health.
Now the rural sewage treatment has been very perfect, unlike the past rural areas have no sewage outlets, I believe that the future of the countryside will be better and better, will also increase the protection of environmental pollution, so that the pollution to the minimum, for us to create a comfortable and beautiful living environment.

There will be an impact, the groundwater is connected, and through infiltration, it will also lead to the contamination of clean water.

In rural areas in the past, although no one in the family dug seepage wells, every household had a sinkhole. In the yard of the countryside, there is often a large pit. The purpose of digging this pit is not only to discharge domestic sewage, but also to accumulate garbage and livestock manure.
Every summer, after fermentation, the soil in this pit will be dug up and used as organic fertilizer. At that time, septic tanks in rural areas were largely open, which not only affected the underground water source, but also was the main breeding ground for mosquitoes and flies in life.
In addition, rainwater will also cause sewage to flow cross-flowing, produce a great odor, pollute the environment more seriously, and have a greater impact on farmers' lives. Maybe it used to be like that in rural areas. In order to remove sewage and rainwater from their home, they dug a deep well in their yard to discharge their sewage.
Obviously, this will pollute water resources. However, in the past, rural areas were sparsely populated, there were no toxic and harmful substances, and the impact was not very serious.
Concrete roads have been built on rural roads, and toilets at home have been built in the same way as city toilets. There will be a septic tank when repairing a toilet, but this is not a seepage well. First, it is shallow, and second, it is all made of cement structures, some of which are plastic, which also prevents the discharged sewage from seeping into the ground and polluting our water resources.
On the other hand, after sewage is discharged through seepage wells or hidden pipes, it is not easy to detect the impact and pollution of pollutants on groundwater and soil in the short term.
People may not notice these problems until livestock or humans drink contaminated groundwater for a long time. Underground aquifers are in constant motion due to the different depths, structures, water volumes, and flow patterns in different regions, as well as the variability and complexity of groundwater aquifer media. At the same time, they also generate the necessary recharge, runoff and excretory processes with the outside world.
As a result, it is difficult to accurately define the scope and extent of water pollutants that have penetrated into underground aquifers through seepage wells or hidden pipes. Now the rural sewage treatment has been very perfect.
-
This is not good, it will affect the surrounding ecological environment, pollute the underground water source, and even change the soil environment, causing water pollution.
-
I think this is very good, you can make reasonable use of water resources, you can use more abundant water, and it is very helpful for rural people.
-
In my view, this is not reasonable and will have a serious impact on the environmental quality and human health of the groundwater in the region.

There are many such seepage wells in the countryside:
Hit a garden pit or garden well, don't hit a square pit, the wall of the square pit is easy to collapse. The best way to do this is to build the walls of the well with stone or brick around the perimeter of the well.
-
This thing doesn't seem to have any specific parameters, I have one in my house, nothing more than to find a suitable place to dig a round or square pit, if the circular amount of water is not large, the diameter is about 2 meters or the square 2 meters is long, the depth is 2 meters to 3 meters, after digging, the inner wall will be flattened, and then it is paved with red bricks, surrounded by red bricks and cement, and the inner wall of the masonry can not be smoothed with cement. Finally, cap with concrete and leave a drain, and that's it.
-
There is no specific standard for digging seepage wells in rural areas, and it is decided according to the soil quality and topography, and it is generally about three meters.
1. The mortar for construction shall be constructed according to the construction mix ratio by mechanical mixing.
2. Choose no cracks, no weathering, the minimum side size is not less than 20cm block stone or the minimum side size is not less than 15cm sheet stone as masonry materials, remove the surface rust.
3. The surface stone adopts rough processing method to ensure that the exposed surface is clean and smooth, and the abdominal stone is larger than 15cm. The staggered joints are layered masonry, and the mortar is dense and full.
-
In the process of drilling, some of the suspended solids in the mud such as the pellet type will still enter the formation with strong permeability, so that the channel connected by the system will be blocked, and there will be some particles inherent in the cement mortar in the pores, so that the resistance of the flushing zone will be significantly improved, and the water content and the saturation of water will drop sharply in this case, so the saturation of the water content of the formation is relatively low. If the water content of the flush zone is very similar to its saturation, it can be preliminarily judged that the damage of the reservoir is mainly the damage of the mud envy solid phase.
If the pollution of the bottom layer is mainly caused by the mud filtrate, the filtrate intrusion of the mud will make the oil and gas be gradually replaced, which also makes the water saturation in the intrusion area gradually increase, so that the permeability of the oil phase is constantly decreasing, so the water saturation in the flushing zone is higher than the water content saturation of the original formation, and the reservoir pollution can be judged to be mud filtrate pollution.

1. Basic knowledge of water purification Natural water sources, including surface water treatment equipment and groundwater treatment equipment, contain a variety of different impurities. The impurities contained in the water source can be divided into three categories: suspended matter, colloidal substance and dissolved substance according to its particle size and form. Impurities in water can also be divided into three categories: inorganic, organic and microorganic.
2. The main characteristic of suspended solids is that they are suspended in moving water, and the state in still water is that the light ones float up and the heavy ones sink. The inorganic suspended solids in surface water are mainly sediment, large particles of clay or mineral waste residue, etc., which have a large proportion and are easy to sink. Suspended organic matter (SOS) is large (e.g. aquatic weeds), small (e.g. algae, bacteria or protozoa) and organic matter from sewage.
Suspended solids with larger particles, such as aquatic weeds, are easy to remove, while smaller particles are difficult to remove.
3. Colloidal impurities in natural water are divided into two categories: inorganic colloids (silicate colloids, clay colloids) and organic colloids (various proteins and humus, etc.). Colloidal impurities are characterized by being relatively stable in water and do not precipitate naturally when left to stand for a long time.
4. The dissolved substances in natural water are: oxygen (O2) and carbon dioxide (CO2) are mainly present in water in a molecular state. The ions that exist in water are basically the result of inorganic salts being dissolved in water, such as calcium, magnesium, iron, carbonate, sulfate, chlorine, etc.
Dissolved impurities cannot be removed by any mechanical or coagulation method, they are stably and evenly dispersed in water.
Water treatment methods can be divided into: clarification and disinfection.
1. Clarification. The object of water clarification treatment is mainly suspended solids and colloidal substances in the raw water, and the turbidity formed by these substances in the raw water is reduced. The specific treatment process can be divided into: coagulation, sedimentation and filtration.
Coagulation. The agent (water purification agent) is put into the raw water, so that the agent and the raw water are fully mixed and reacted (that is, the coagulation process is carried out in the reaction pool), so that the suspended solids and colloidal impurities in the water form large particles of flocs that are easy to precipitate, commonly known as "alum flowers".
Precipitation. The raw water entrained by the coagulation process carries large particles of flocs into the sedimentation tank at a certain water flow rate, and the gravity separation is carried out through the sedimentation tank, and the impurity particles with large specific gravity in the water sink to the bottom of the sedimentation tank for discharge.
Filtration. After the raw water passes through the coagulation and sedimentation process, the turbidity of the water is greatly reduced, but the sedimented water flowing into the pool through the sump still has some fine impurities, and the fine impurities in the water are intercepted by the granular filter material (such as quartz sand, anthracite, etc.) in the filter tank, so that the turbidity of the water is further reduced. When the turbidity of the raw water is low, the raw water after the input can also be directly filtered without coagulation, sedimentation and other treatment processes.
2. Disinfection. When the raw water is coagulated, precipitated and filtered, it flows into the clear water pool through the pipeline, and must be disinfected, and the disinfection method is to put chlorine, bleaching powder or other disinfectants into the water to kill the pathogenic microorganisms in the water. There are also methods such as ozone or ultraviolet irradiation to disinfect water.

Sewage from the surface flows into the well, which means raising the perimeter of the well to clean up the sewage from the well.
-
If it is necessary to treat the surface sewage flowing into the well, then it is best to replace the pipe with a dedicated channel for another sewage channel.
-
This should be done through this slab pipe, through this pipe, and then the sewage should be discharged into this pipe.
-
It can't be treated, it can only be drained, but the groundwater will definitely have an impact.
-
If the well is filled with sewage, the well needs to be completely drained, and when the water level is restored, it needs to be drained again, and the water will be clean many times (maybe even a dozen times).
Traditional large wells can be cleaned up after the water is drained, and it is necessary to pay attention to safety, and it is necessary to use blowers and air ducts to the bottom of the well for ventilation from two hours before the person is discharged to the end of the work, and be aware of the danger of possible collapse.
If the groundwater is polluted as a whole, then the well can only be abandoned and replaced with a new source of water (the well should be filled for safety) or continue to dig deeper into the deeper unpolluted aquifer below, because the contamination of shallow groundwater will take at least thousands of years to be largely eliminated, and the deep ones will take tens of thousands of years.
-
The sewage wells in the countryside also depend on everyone to maintain them, and if others don't pour things into them, you will be embarrassed to do it yourself, which is a common agreement for everyone, not according to your own thoughts.
-
First of all, determine what are the water quality or pollutants of the sewage being dumped? Are there any toxic ingredients? What is the pH value? Whether it can meet the requirements of sewage entering the sewage pipe network, it is necessary to obtain the consent of the sewage well management unit first.
-
Definitely not, it will increase the pollution of groundwater. Sewage can only be discharged after it has been treated to meet the standards.
-
Rural and urban hospitals are actually not welcome, if you really think about it, you can do it, it's not safe.
-
In principle, no!
Problems with all aspects of pipe unclogging are needed!
I don't think it's that rural people think it's useless to go to university, it's just that the difference between the rich and the poor is gradually becoming obvious because of the different development conditions between urban and rural areas. In the past, many people thought that it was a great thing for a village to have a college student, but now since the beginning of reform and opening up, starting from the new countryside, there are no longer so many restrictions, as long as the children in the rural areas are not particularly poor, and it is difficult to maintain a basic life, they can receive the same education as the children in the city. >>>More

Why can't you get married, what's wrong with rural people, although rural people may have no culture and no background, but some of them are simple and beautiful, I really don't know why you ask such a question, but I think there must be a reason why you ask this kind of question, either you look down on rural people from your heart, you feel that they are vulgar and uneducated and you don't want to marry rural people, or you are afraid of the opposition of the two families, and you are afraid that life after marriage is full of unhappiness. >>>More
Rural marriage involves everything such as the time of marriage, the place of marriage, the direction of marriage, etc., following the way left by the ancestors, blind dates, touching fate, and then witnessing, greeting, and receiving relatives. No matter how the man and woman know each other, there must be a matchmaker, an intermediary, to discuss marriage.
