Product Name: Rural sewage treatment equipment

Details:

The problem of rural domestic sewage pollution has become a problem that cannot be ignored and urgently needs to be resolved. The integrated sewage treatment equipment has a series of advantages such as low investment, low energy consumption, high treatment efficiency, small floor space and convenient management, and is suitable for promotion in rural areas.

Characteristics of rural domestic sewage water quality:

The quality of rural domestic sewage is related to various factors such as the geographical environment, economic development level and living habits of rural areas. According to the existing survey data, the nature of most rural domestic sewage is not much different, and the water quality of sewage is relatively stable. Compared with urban sewage, organic matter, nitrogen, phosphorus and other nutrients are high in content, generally do not contain toxic substances, sewage It also contains synthetic detergents as well as bacteria, viruses, parasite eggs, etc., and the water quality varies from time to time.

Main process of rural domestic sewage treatment equipment: A/O (anaerobic-aerobic activated sludge method).

A/O process principle: Anaoxic/Oxic (A/O) is a sewage biological treatment process consisting of two parts of anaerobic and aerobic reactions. After the sewage enters the anaerobic tank, it is mixed with the return sludge. The polyphosphate bacteria in the activated sludge absorbs the BOD in the sewage in a large amount in this process, and releases the phosphorus in the sludge into the mixed solution in the form of orthophosphate. After the mixed liquid enters the aerobic tank, the organic matter is oxidatively decomposed, and the polyphosphate bacteria absorbs the orthophosphate in the mixed solution to the sludge in a large amount. Since the phosphorus accumulating bacteria absorb more phosphorus under aerobic conditions than the phosphorus released under anaerobic conditions, the sewage undergoes the "anaerobic-aerobic" alternating action and the sludge separation of the secondary settling tank to finally achieve phosphorus removal. the goal of.

Characteristics of rural domestic sewage treatment equipment:

1. The whole set of equipment can be buried in the ground. The surface above the equipment can be used as greening or other land. It does not need to build houses, heating, and heat preservation. It can also be placed on the ground and has a relatively small footprint.

2. The secondary biological contact oxidation treatment process adopts push-flow biological contact oxidation, and its treatment effect is better than the complete mixed or two-stage series fully mixed biological contact oxidation tank. Compared with the activated sludge tank, it has small volume, strong adaptability to water quality, good impact load resistance, stable effluent quality and no sludge expansion. The membrane adopts a membrane aerator and a novel elastic three-dimensional filler, which has a large specific surface area, microbes are easy to hang the membrane, and the membrane is removed. Under the same organic matter load condition, the organic matter removal rate is high, and the solubility of oxygen in the air in water can be improved.
