Complaint
Domestic sewage treatment refers to the discharge of sewage discharged from residents' daily life after treatment to meet the sewage discharge standard. It mainly comes from residential buildings and public buildings, such as houses, institutions, schools, hospitals, shops, public places and industrial enterprises. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrate, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasitic worm eggs and enteric infectious viruses, etc.). The organic matter existing in domestic sewage is extremely unstable, easy to rot and produce odor. Bacteria and pathogens take organic matter in domestic sewage as nutrition and multiply in large numbers, which can lead to the spread of infectious diseases.
