Description
Technical Field
The utility model belongs to the relevant field of sewage treatment, concretely relates to novel micro-power domestic sewage treatment system.
Background
Domestic sewage is wastewater discharged in daily life of residents, and sewage generated in the life process of human beings becomes one of main pollution sources of water bodies. Mainly feces and washing sewage. The pollutants contained in the domestic sewage are mainly organic matters and a large number of pathogenic microorganisms. The domestic sewage contains a large amount of organic matters, such as cellulose, starch, saccharides, fat protein and the like; also frequently contain pathogenic bacteria, viruses and parasite eggs; chlorides, sulfates, phosphates, bicarbonates, and sodium, potassium, calcium, magnesium, and the like, of inorganic salts. These organic substances present in domestic sewage are extremely unstable and easily decay to produce offensive odors. Bacteria and pathogens propagate in large quantities by taking organic matters in domestic sewage as nutrition, and can cause epidemic of infectious diseases.
The biochemical treatment of domestic sewage in the prior art has the defects of dispersed process, complex structure, high control requirement, large starting difficulty, large process control difficulty, poor stability of treated effluent, periodic maintenance and management, long starting time of the treatment process, difficult operation, periodic cleaning or replacement of fillers, large amount of waste gas and sludge (secondary pollution) generated by the treatment process, deep treatment, large one-time investment, large energy consumption and high operating cost of a wastewater treatment device, and needs a special site for wastewater treatment.
Disclosure of Invention
