Background

Sewage treatment is a process of purifying sewage to meet the water quality requirement of draining a certain water body or reusing the sewage. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is increasingly used in daily life of common people.

Municipal sewage comprises domestic sewage, industrial wastewater, runoff sewage and the like, and is collected by a municipal drainage pipe network and conveyed to a sewage treatment station for treatment. The urban sewage treatment adopts various forms according to local conditions, and natural purification of water and purification of sewage in the utilization process are considered according to the utilization or discharge direction of the urban sewage. The treated sewage, whether used for industry, agriculture or discharge, should meet the national regulation standard.

At present, municipal sewage treatment is classified into three levels, i.e., primary treatment (mechanical treatment), secondary treatment (biological treatment), and tertiary treatment (advanced treatment). The first-stage treatment mainly adopts structures such as a grating, a grit chamber, a sedimentation tank and the like to remove insoluble suspended matters and the like in the sewage. The secondary treatment mainly removes colloid and soluble organic matters in the effluent of the primary sedimentation tank. Typical plants are a biological aeration tank (or biological filter) and a secondary sedimentation tank. The third-stage treatment mainly removes nutrients (nitrogen and phosphorus) and other refractory substances in the second-stage effluent. The main methods include physical and chemical methods such as flocculation, filtration, adsorption, ion exchange and the like. The purpose of the tertiary treatment is to avoid water eutrophication or reuse water. The urban sewage treatment generally uses primary treatment as main treatment and secondary treatment as main treatment, and the tertiary treatment is rarely used.

Municipal sewage contains organic matters such as carbohydrates, proteins, amino acids, fats and the like, is relatively suitable for the growth of bacteria, is a place for the survival and propagation of bacteria and viruses, and generally does not contain toxicity. The prior sewage treatment device for municipal engineering has an unsatisfactory effect on the pre-filtration treatment of sewage.
