Abstract

The invention provides an advanced treatment system for urban sewage and an advanced treatment process using the same, which can filter out harmful substances in water and ensure the quality of effluent water. The main technical solution of an advanced treatment system for urban sewage is that the system includes sequentially connected: coarse grid tank, water inlet pump room, fine grid tank, grit chamber, A2/O reaction tank, secondary sedimentation tank, and lifting pump room , mixer, high-efficiency fiber filter and ultraviolet sterilizer, and the fiber filter material of the high-efficiency fiber filter is polypropylene fiber. A process for advanced treatment using the above-mentioned urban sewage advanced treatment system: sewage enters the coarse grid, then enters the fine grid, grit chamber, A2/O reaction tank, and secondary sedimentation tank in sequence after passing through the water inlet pump room, and passes through the lifting pump After the room is lifted, it enters the mixer, the high-efficiency fiber filter, the ultraviolet sterilizer in turn, and finally comes out the standard water.

Description

technical field [0001] The invention relates to an advanced treatment system for urban sewage and a technology for advanced treatment using the system, which belongs to the technical field of sewage treatment. Background technique [0002] With the development of modern industry, the degree of pollution and destruction of water resources is becoming more and more serious. According to conventional water treatment methods, it is difficult to completely remove harmful substances in water, which brings great harm to people's life and health. In order to meet the requirements for high-quality water, scientific and technical personnel have carried out a lot of research work and proposed various water treatment methods and water treatment systems. [0003] At present, there are several forms of advanced sewage treatment: 1) Biochemical process, which can meet the standard, but the process is long, the investment is large, and the quality of the effluent is not very stable. 2) Me...
