Integrated sewage treatment equipment for domestic sewage

Introduction to integrated sewage treatment equipment for domestic sewage:

Domestic sewage treatment equipment is a device used to treat sewage in daily life. The application of room temperature anaerobic fermentation technology in small-scale domestic sewage purification biogas digesters, based on the principle of "multi-stage self flow, step-by-step degradation", establishes a new device of first stage anaerobic fermentation and second stage facultative digestion filtration. It consists of processes such as anaerobic fermentation, facultative digestion filtration, sewage reflux, and packing.

Working principle of integrated sewage treatment equipment for domestic sewage:

The removal of organic pollutants and ammonia nitrogen mainly relies on the AO biological treatment process in the equipment. The working principle is at level A. Due to the high concentration of organic matter in sewage, microorganisms are in a state of hypoxia. At this time, microorganisms are facultative microorganisms. Therefore, level A tanks not only have a certain function of removing organic matter, reducing the organic load on subsequent aerobic tanks, and reducing the concentration of organic matter, but there is still a certain amount of organic matter and high NH3-N present. In order to further oxidize and decompose organic matter, and ensure smooth carbonization, an aerobic biological contact oxidation tank with low organic load is set up at level O. There are mainly aerobic microorganisms and autotrophic bacteria (nitrifying bacteria) in the O-level pool.
