How to deal with rural sewage treatment!

MBR biofilm reaction technology can be used to treat rural domestic sewage, and the effluent quality has reached the national first-class A standard, which can make the treated sewage reused, such as: toilet flushing, car washing, greening, irrigation, etc. Detail.

This is very simple, generally speaking, the upper set of integrated equipment can be, generally for the new rural communities, highway service areas, airports and other areas that do not have access to the municipal pipe network, there are many such equipment, and the process is also very diverse, and it can be flexibly chosen

Rural community sewage is generally a good process, if necessary 18253646120 (integration) Yaoshun environmental protection.

Rural sewage is generally enough to make a grid pond, a sedimentation tank, and an artificial wetland.

The best way to treat rural domestic sewage is as follows:

The first is the "anaerobic purification tank + storage pool + comprehensive utilization" model. Centralized collection of toilet feces, the selection of "easy maintenance, low cost, low energy consumption" sewage treatment technology, the use of "single household, joint household, centralized" different forms of anaerobic purification tank grading treatment standards, through land consumption to achieve comprehensive agricultural utilization.

The second is the processing mode of the factory. The domestic sewage around the town will be included in the urban sewage treatment pipe network for unified treatment, and after pretreatment, it will be discharged into the urban sewage treatment plant (station) for centralized disposal and discharge.

The third is the treatment mode of integrated sewage treatment facilities. For domestic sewage in environmentally sensitive areas, integrated sewage treatment facilities are used to centrally treat and discharge up to the standard. Implement the resource utilization of rural domestic sewage according to local conditions, effectively reduce labor costs, realize effective treatment of domestic sewage, and form a win-win situation between domestic sewage treatment, ecological agriculture development and ecological civilization construction.

Sewage treatment precautions

1. The quality of sewage treatment project construction is closely related to the construction team, and it is recommended to choose a professional company, such as Chenmai Wisdom. Because this kind of company often has rich experience, engaged in the construction of rural sewage treatment projects of professional construction team, in the construction process will be in strict accordance with the drawings of the construction, there will be no corners, elevation, material selection does not match, etc., the station area construction related information needs to establish a systematic ledger, for acceptance inspection.

2. The sewage pipe network in the rural cavity and rotten areas should avoid settlement, water leakage, damage and other phenomena, so the selection of pipes needs to be cautious, and the application of concrete pipes, metal pipes, corrugated pipes and PE pipes needs to be adapted to local conditions.

3. Rural sewage treatment equipment should choose cost-effective, stable water quality, convenient maintenance equipment, and the tonnage of the equipment needs to be highly matched with the official water volume of the project to avoid equipment idling or over-operation.

4. The water volume design should be within the scope of bearing, especially in some areas, the rain and sewage are not diverted, and the water volume in the rainy season is far more than usual, which is easy to cause equipment failure. In addition, the pH value of the sewage directly affects the efficiency of the equipment when it enters the domestic sewage treatment equipment, and the water quality of the bucket leakage is too acidic or alkaline, which will affect the normal growth of the biofilm, which needs to be strictly controlled.

In China's rural areas, due to the lack of effective sewage treatment methods, a large amount of sewage is directly discharged into rivers, lakes and other water sources, which seriously affects the local environment and the health of residents. In order to solve this problem, many experts and scholars have begun to devote themselves to the study of rural sewage treatment technology, among which microbial technology has become an important solution.

Microbial destove technology is a method of using the biological characteristics of microorganisms to treat sewage, through the use of microbial adsorption, decomposition and transformation, it can effectively convert organic matter, nitrogen, phosphorus and other substances in sewage into harmless substances, so as to achieve the purpose of purifying water quality. In terms of rural sewage treatment, microbial technology has the following advantages:

First of all, microbial technology can adapt to various water quality conditions, and has a certain adaptability to different types of sewage. Secondly, microbial technology can reduce the cost of treatment, and compared with traditional physicochemical methods, microbial technology is less expensive to operate and more feasible. In addition, the sludge treated by microbial technology can be used as organic fertilizer, which is conducive to the sustainable development of agriculture.

At present, microbial technology has been applied in some regions. For example, in Liuhe District, Nanjing, Jiangsu Province, the microbial method has been used to treat rural sewage, and the treatment effect has been remarkable, and the water quality has been significantly improved. This success story also provides a reference for other regions.

Although microbial technology has broad application prospects in rural sewage treatment, there are still some problems that need to be solved. For example, microbial technology requires long treatment cycles and is not suitable for treating large quantities of wastewater. In addition, microbial technology is highly sensitive to environmental factors, requiring strict control of factors such as water quality and temperature.

Therefore, in the future, it is necessary to further research and innovate on the basis of microbial technology, explore more efficient and sustainable rural sewage treatment methods, and make greater contributions to ensuring the life and health of rural residents and environmental protection.

1. Physical treatment method: the treatment of insoluble pollutants in suspension state in wastewater separated by physical action, and the treatment method based on the principle of heat exchange also belongs to the physical treatment method.

2. Chemical treatment method: wastewater treatment method that separates and dissolves into harmless substances through chemical reaction and mass transfer. coagulation, neutralization, redox, etc.; The processing units based on mass transfer are:

Extraction, stripping, blowing, adsorption, ion exchange, electrodialysis and reverse osmosis.

3. Biological treatment method: through the metabolism of microorganisms, the organic pollutants in the wastewater in the state of solution, colloidal and fine suspension are converted into stable and harmless substances. Aerobic biological treatment methods are divided into two types: activated sludge method and biofilm method.

The activated sludge process itself is a treatment unit that can be operated in a variety of ways.

4. Biological contact oxidation method: use biological contact oxidation method to treat wastewater, fill the filler with some biofilm, sewage and biofilm will be widely contacted, the treated wastewater is discharged into the biological contact oxidation treatment system and mixed with domestic sewage for treatment, chlorine disinfection and discharge.

Wetland domestic sewage treatment system: Sewage is put into the area where swamp plants grow, and the elements in the sewage are absorbed by plant roots and microorganisms. Soil Purification Domestic Sewage Treatment System:

When the sewage is transferred to the soil nearly 50 meters underground, the sewage begins to spread slowly, and there are many microorganisms on the soil surface, and the pollutants in the sewage will be absorbed and degraded by the roots. <

1. Wetland domestic sewage treatment system: put sewage into the place where swamp plants grow, and absorb the elements in the sewage through plant roots and microorganisms.

2. Soil purification domestic sewage treatment system: the sewage is transmitted to the soil nearly 50 meters underground, the sewage begins to spread slowly, there are many microorganisms on the soil surface, and the pollutants in the sewage will be absorbed and degraded by the roots.

3. Biological treatment domestic sewage treatment system: Biological treatment domestic sewage treatment system is divided into two categories, one is anaerobic biological treatment system, and the other is aerobic biological treatment system. Aerobic biological treatment systems are commonly used to deliver oxygen to the wastewater to cultivate microorganisms, which will degrade the organic matter in the wastewater into inorganic matter.

Provide several rural domestic sewage treatment measures from the perspective of **:

In order to effectively implement responsibilities and strengthen the supervision of sewage treatment facilities, the relevant departments should clarify the division of responsibilities and cooperate with each other to avoid the phenomenon of unclear rights and responsibilities of sewage treatment and poor supervision. At the same time, it is necessary to establish a departmental relationship mechanism, optimize the overall design and planning of sewage treatment facilities, establish and improve the operation and maintenance management mechanism of sewage treatment facilities, and reduce the cost of sewage treatment construction and operation and maintenance management. In addition, the overall project packaging model of sewage treatment is adopted to attract social funds to participate in rural domestic sewage treatment, provide financial support for rural domestic sewage treatment, and improve the professional and socialized operation and maintenance management level of rural domestic sewage treatment facilities.

In view of the current situation of poor operation and maintenance management of rural sewage treatment and utilization facilities in China, relevant departments in various localities can adopt a market-oriented operation method to ensure the smooth operation and maintenance management of rural sewage treatment facilities according to the actual situation.

The relevant departments should first of all let farmers understand the concept of water resource use and commercialization of water treatment through publicity and education, and then formulate scientific and reasonable collection standards based on the current situation, characteristics and maintenance costs of local villages, so as to raise funds for sewage treatment projects.

At present, in the process of rural construction and rural domestic sewage treatment, in addition to combining their own economic strength and regional characteristics, scientific planning, reasonable selection of sewage treatment processes and facilities, all localities must also expand funds, attach importance to personnel training, strengthen publicity and education, and adopt market-oriented operation, to a large extent, to ensure that the funds are sufficient, the talents are excellent, the masses support, and the operation and maintenance are effective, so that the completed sewage treatment facilities can play a full role, so that remote rural areas can build sewage treatment facilities as soon as possible. Achieve the goal of sustainable development of domestic water environment.
