In general, there is no sewer in the countryside, so how is the excrement disposed of in the end?

Concentrated excrement is generally discharged into the sweat toilet, where feces accumulate all the time.

At present, the rural areas still dispose of human excrement very ecologically and environmentally friendly. Septic tanks are a common way to dispose of human waste in rural areas. Septic tanks are generally built at the back of the house or on the side of the house to collect human waste, bathing water and other domestic sewage.

Many septic tanks are next to vegetable gardens, and the waste liquid and waste residue in the septic tank are directly used to water vegetables, which is a very good organic fertilizer for vegetables and fruits.

Rural excrement is nothing more than domestic pollution and feces. Generally speaking, domestic sewage is poured into a dry toilet, and feces are naturally in it. A septic tank is a new type of toilet.

In rural areas, this septic tank solves not only the problem of excrement, but also the problem of sewage. During the construction process, it is necessary to establish the principle of big but not small to reduce the number of cleanings.

The domestic water (not excrement) discharged in rural areas is mainly natural runoff and natural evaporation, but modern rural areas are not completely devoid of sewers, and when every family is building a house, a simple sewer will be set up to discharge indoor water to the street. And depending on the topography, it will also establish a summary ditch, especially in the countryside in hilly, mountainous and other areas, basically relying on the natural landform to set up a main ditch or sewer.

Of course, there are some exceptions, such as the rural areas in the plains, because the terrain difference is relatively small, the discharge of domestic water is easy to accumulate around the house, so many people in the plain area will dig a water pit around the house, and the domestic water will be collected into the water storage pit, either naturally evaporated, or pumped regularly.

The starting point of this problem should be to ask the problem of rural water pollution, indeed, when the industrial products have not entered thousands of households, the discharge of rural domestic water will not pollute the environment at all, and even gather to the lowest point of the village, and can be directly used after simply passing through the natural cycle, and at present, with the popularization of chemicals, rural domestic water has also become a high source of pollution.

As far as the simplest laundry detergent and detergent are concerned, they contain a lot of chemical elements, and after the domestic water is collected into the lake, it is easy to cause the lake enrichment, which not only affects the surface water quality, but also affects the surrounding cultivated land. What's more serious is that the discharge of rural domestic water has affected the groundwater resources, the wells in the rural areas used to be sweet and clear, and they can be directly drunk without even boiling after pumping, while many of the water in the shallow wells have turned yellow, a musty smell, and cannot be directly drunk, and the deep wells also have many chemical elements that exceed the standard.

From the perspective of water recycling, this is a very scary thing, because groundwater restoration and treatment is far more serious than surface water. Fortunately, we have now realized the seriousness of the problem and have gradually begun to treat rural sewage, such as installing sewage storage devices.

Daily domestic water is generally poured directly on the ground, and after a while, it will be dried, and it will be poured into the surrounding garbage heap, which can also be quickly solved, or directly poured into the sewer, and the domestic water will also flow into the ground.

Normally, it is poured into the ground or in the ditch, and there is a fixed place for garbage storage in the countryside, so most people will discharge some dirty water or other things into it.

The daily domestic water in rural areas is generally used to irrigate the fields, or stored for later use, for the cleaning of some items in daily life, and the water will also be reused.

Because there are fixed-point drainage pipes in the countryside, the drainage of people in the countryside will be stipulated in one place, and then there will be a professional master to deal with it.

1. Domestic wastewater: It can be discharged to the outside and will be absorbed by the land, with almost no taste and no impact on the environment. 2. Excrement:

Build septic tanks. Dirt ferments to produce biogas, which is useful. 3. Underground infiltration wells:

Without affecting the foundation, after digging the well, the well is reinforced with bricks to prevent collapse, and then the wellhead is sealed, and the sewage can be directly discharged into the well. <

2. Excrement: build a septic tank. Dirt ferments to produce biogas, which is useful.

3. Underground infiltration well: without affecting the foundation, after digging the well, the bricks should be attached to the well to prevent it from collapsing, and then the wellhead will be sealed, and the sewage can be directly discharged into the well.

The treatment of sewage will be integrated into the sewage treatment plant. After the sewage treatment plant has treated the sewage, it is still discharged into the rivers, lakes and seas, and then it is taken up by the tap water intake facilities.

1. Sewage treatment:

The process of purifying wastewater in order to meet the water quality requirements for draining a body of water or reusing it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily life of ordinary people.

2. Classification: According to the classification of sewage, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is the sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and organic matter, including: floating and suspended large and small solid particles; gelatinous and gelatinous diffuses; Pure solution.

According to the quality of water pollution, there are two types of water pollution: one is natural pollution; The other type is man-made pollution, which is currently more harmful to water bodies. Water pollution can be divided into three categories: chemical pollution, physical pollution and biological pollution according to different pollution impurities.

The main pollutants are: untreated industrial wastewater; untreated domestic sewage; Farmland sewage with a large amount of chemical fertilizers, pesticides, and herbicides; industrial waste and household waste piled up near the river; Soil erosion; Mine sewage.

3. Treatment:

Village and town sewage is mainly composed of domestic sewage and agricultural wastewater. The composition of domestic sewage is relatively fixed, mainly containing carbohydrates, proteins, amino acids, fats and other organic matter, which is more suitable for the growth of bacteria and becomes a place for bacteria and viruses to survive and reproduce; However, domestic sewage generally does not contain toxicity and has a certain fertilizer effect, which can be used to irrigate farmland. The composition of agricultural wastewater is diverse, and different seasons, different places, and villages and towns with different development goals need different treatment methods.

In the treatment of sewage, in order to reduce the amount and complexity of sewage discharge, it is necessary to separate the flushing water (black water) and other domestic water (gray water) in the domestic water in combination with the construction of biogas digesters that the state is vigorously promoting. Grey water is treated with a natural purification system, and black water and human and animal manure are treated by anaerobic digesters, which can not only reduce the discharge, complexity and treatment cost of sewage, but also have great significance for the development of clean and new energy in rural areas, protect the living environment, and promote the sustainable development of rural economy and society.

The role of the sewage treatment station is to treat production and domestic sewage to meet the specified discharge standards, and is an important facility to protect the environment. Sewage treatment stations in industrially developed countries have been common, while there are few sewage treatment stations in villages and towns in China, but they will gradually increase in the future. In order for these sewage treatment stations to really function, they also need to rely on strict discharge systems, organization and management systems to ensure them.

There are two types of sewers in the city. One is the downspout, including kitchen drains and bathroom drains. This part of the water is relatively clean, and can be merged into the main sewer pipeline of the city, summarized into the urban sewage treatment center, and can be discharged into the nearby river after precipitation and chemical treatment, and the test can only be discharged into the nearby river.

The other is the fecal pipeline, which generally enters the septic tank and can only be discharged after precipitation, fermentation and chemical treatment

Simply purify it and drain it into the ocean.

The city's waterworks, which are simply purified and then flow downstream to the sea, are being purified.
