Treating apparatus for wastewater at sewage draining exit

Abstract

The invention provides a sewage outlet treatment device, which belongs to the technical field of water treatment. It is characterized by the use of anaerobic decomposition, including: two nested inner bags and outer bags, flange connection at the mouth of the bag, water discharge pipe, gas collection port, gas discharge pipe, automatic pulse igniter, automatic timing drain valve The waste water from the sewage outlet enters the inner bag, the sediment settles in the inner bag, the treated gas and water enter the outer bag, the gas passes through the gas discharge pipe and then enters the gas collection port, and the gas passes through the gas collection port at the end of the gas discharge pipe Ignited by an automatic pulse igniter, the automatic timed drain valve discharges waste water from the drain according to a specific time. The device is efficient in decontamination, requires small space, low energy consumption, is simple and easy to implement, low in cost, convenient in operation and maintenance, and has a large development space in the field of environmental protection water treatment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection water treatment and is mainly applied to the treatment of sewage outlets of water bodies such as river courses, lakes and breeding farms. Background technique [0002] Most of our country's rivers, lakes, reservoirs, ponds and other surface waters are seriously polluted. A large amount of untreated industrial sewage, domestic sewage, and agricultural irrigation water are directly discharged into rivers, rivers, lakes, and seas, causing water pollution, black and smelly water. With the continuous deepening of my country's urbanization process, the discharge of urban sewage continues to increase. At present, many urban sewage are directly discharged into nearby rivers without any treatment. Many urban rivers are black and smelly. Although the government has intercepted sewage, However, the phenomenon of incomplete sewage interception and incomplete sewage interception still exists, ...

Problems solved by technology

With the continuous deepening of my country's urbanization process, the discharge of urban sewage continues to increase. At present, many urban sewage are directly discharged into nearby rivers without any treatment. Many urban rivers are black and smelly. Although the government has intercepted sewage, However, the phenomenon of incomplete sewage interception and incomplete sewage interception still exists, and untreated sewage enters the river, thus causing difficulties for further ecological restoration of water bodies

[0003] Sewage outlet treatment is a necessary and beneficial supplement to the ecological restoration of water bodies, and has even become the key to the success or failure of water body ecological restoration. Without sufficient sewage interception and sewage outlet treatment, the water body ecological restoration will have poor impact resistance and the system will turn black and smelly again. Phenomena happen from time to time

[0004] Chinese invention patent CN205347124U uses the method of sewage treatment plant to treat the sewage at the sewage outlet, but because the system requires a large amount of infrastructure, power supply, and covers a large area, it is not suitable for the treatment of sewage outlets in urban rivers; Chinese invention patent CN205313327U adopts isolation The technology of net cage and microbial film formation is used to treat the sewage outlet, but because the area of ​​microbial film formation is not large, the anti-scourability of pollutants is poor, so the treatment effect is not ideal
