In the countryside! What is the most scientific and low cost method of sewage treatment?

The decentralized treatment method can be treated according to the combined process of different influent water quality. For details, you can see the "Village Sewage Treatment Case Collection" of the Construction Engineering Publishing House.

Anaerobic fermentation, can be ** biogas.

Commonly used rural sewage treatment methods: anaerobic hydrolysis, water drop oxygenation contact oxidation, constructed wetland, oxidation pond, activated sludge method, membrane technology sewage treatment technology, etc.

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

Rural domestic sewage treatment processes are:

Domestic sewage purification digester.

Stable pond domestic sewage treatment technology.

Constructed wetlands. land treatment technology, etc.

In the selection of treatment technology, it is necessary to follow the selection principles of mature technology, stable treatment effect, low infrastructure investment and operating costs, convenient operation management, flexible operation, advanced technology and equipment, and reliability.

For example, if the amount of domestic sewage produced in rural areas in the north is small, the water quality is single, and there is more land for sewage treatment project construction, priority can be given to the use of domestic sewage purification digesters. If there is a pit pond that can be used, the combined process of domestic sewage purification biogas digester + stabilized pond treatment can also be selected.

In addition, although the land treatment technology has not been widely promoted in China, in view of the good pollutant removal effect of this technology, it is a simple, reliable, practical, low energy consumption, low cost small sewage treatment system, it is suggested that the technology can be tried to treat rural domestic sewage in areas with conditions.

The first is to select the best wastewater treatment process. It is necessary to select the treatment process according to the geographical topography, population distribution, economic level, climatic conditions and regional environmental capacity, although some technologies are advanced, but the complexity is high, the region is difficult to manage, the operation is difficult, and the high cost is not conducive to the long-term operation of the project. It is suggested that combined with the actual situation of silver sales in various places, Zhaoxin should carry out extensive discussion and research, choose more practical technical solutions, and reduce the cost of sewage operation from the source as much as possible.

Secondly, professional and large-scale operation and maintenance management can be an inevitable choice to reduce costs. Due to the strong technical and professional nature of sewage treatment projects and the lack of professional personnel in local areas, village and town sewage treatment projects should be handed over to professional companies to operate. Promote large-scale operation, through the establishment of a more integrated operation and maintenance model, scientific allocation of management personnel, inspection personnel, and first-class monitoring platform, and coordinate the inspection, maintenance and management of regional town-level and village-level sewage treatment facilities, so as to reduce the operation cost of sewage treatment in Hedoulun County with the large-scale effect of sewage treatment.

Electricity cost is an important part of sewage treatment cost, and it is the most direct cost expenditure, so it is advisable to choose energy-saving micro-power equipment when selecting equipment for rural sewage treatment projects. If the electricity cost of town and village sewage treatment is incorporated into the agricultural electricity system, this will greatly reduce the cost of electricity bills.

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.
