Environment-friendly sewage treatment device and treatment method thereof

Technical Field

The invention relates to the technical field of sewage treatment, in particular to an environment-friendly sewage treatment device and a treatment method thereof.

Technical Field

Sewage refers to discharged water from life and production which is polluted to a certain extent, and is classified according to sewage sources, and sewage is generally classified into production sewage and domestic sewage. The production sewage includes industrial sewage, agricultural sewage, medical sewage, etc. Domestic sewage is waste water discharged in daily life of residents, and mainly originates from residential buildings and public buildings, such as houses, institutions, schools, hospitals, shops, public places, industrial enterprise toilets and the like. The sewage generally contains a large amount of pathogens, nitrogen and phosphorus compounds, organic pollutants, inorganic pollutants, detergents and the like, and also contains a large amount of bacteria, parasite eggs and other harmful substances. Thus, sewage treatment is now strongly advocated for environmental health.

Sewage treatment is a process of purifying sewage to meet the water quality requirement of being discharged into a certain water body or reused. The sewage treatment is widely applied to various fields of buildings, agriculture, traffic, energy sources, petrifaction, environmental protection, urban landscapes, medical treatment, catering and the like, and the sewage treatment is increasingly carried into the daily life of common people. When the existing sewage treatment equipment is used for treating sewage, aerobic microorganism sewage treatment strains are often used, the aerobic microorganism sewage treatment strains are added into the sewage to decompose organic pollutants in the sewage into water and carbon dioxide or convert the organic pollutants into nutrients of the sewage treatment microorganisms, and the nutrients are utilized for propagation, so that the pollutants can be just degraded in the process, the aim of removing the sewage and deodorizing is achieved, and the treatment method is called aerobic treatment and is the most utilized method is the activated sludge method.
