Description

Domestic sewage purifying and discharging system

Technical Field

The invention relates to the technical field of domestic sewage treatment, in particular to a domestic sewage purification and discharge system.

Background

The urban sewage treatment process generally determines the sewage treatment degree and the corresponding treatment process according to the utilization or discharge direction of urban sewage and considering the natural purification capability of water body. The treated sewage, whether used for industry, agriculture or recharging and supplementing groundwater, must meet the relevant water quality standards issued by the country. Modern sewage treatment technology is divided into primary, secondary and tertiary treatment technologies according to treatment degree. The first stage sewage treatment uses physical methods, such as screening, precipitation, etc., to remove insoluble suspended solids and floating materials from the sewage. The secondary sewage treatment mainly adopts a biological treatment method, namely, a process of converting substances through the metabolism of microorganisms, so that various complex organic matters in the sewage are oxidized and degraded into simple substances. Biological treatment has certain requirements on sewage quality, water temperature, dissolved oxygen in water, pH value and the like. The sewage three-stage treatment is to remove insoluble organic matters, phosphorus, nitrogen and other nutritive substances in the sewage by using physical and chemical methods such as coagulation, filtration, ion exchange, reverse osmosis and the like on the basis of the first-stage and second-stage treatment. The composition of pollutants in sewage is very complex, and the combination of the methods is often required to meet the treatment requirements. The primary treatment of sewage is pretreatment, the secondary treatment is main body, and the treated sewage can generally reach the discharge standard. The three-stage treatment is advanced treatment, the water quality of the effluent is better, and even the effluent can reach the standard of drinking water quality, but the treatment cost is high, and the application is less except for some countries and regions with extremely water shortage. Many cities in China are building up and expanding sewage secondary treatment plants to solve the increasingly serious water pollution problem.
