Complete set of equipment and process for dual-effect physical and chemical treatment of domestic sewage

Abstract

The invention relates to a complete set of equipment and a process for dual-effect physical and chemical treatment of domestic sewage. The treatment equipment and process mainly include: a domestic sewage source, a primary filtration regulation tank, a physical electric flocculation module group, a solid-liquid separator module group, a secondary filter, a high-efficiency strong oxidation module group, a purification storage tank, a tertiary filtration tank, a four-stage MBR membrane treatment device and a purification reuse water interface. The domestic sewage treatment complete equipment andprocess of the invention mainly adopt a multi-stage treatment process, wherein the working principle of the physical electric flocculation module group and the high-efficiency strong oxidation modulegroup is a double-effect physical-chemical pure physical method, and the process has high removal efficiency, low cost, no additive and no secondary chemical pollution. The invention aims at achieving the standard discharge and reuse of reclaimed water through the domestic sewage treated by the complete set of equipment and processes.

Description

technical field [0001] The invention relates to a complete set of equipment and technology for double-effect physical-chemical treatment of domestic sewage, and also relates to a complete set of equipment for double-effect physical-chemical treatment of domestic sewage. Background technique [0002] Due to the development of cities and the rapid increase of population, the discharge of domestic sewage has increased sharply, which has polluted the existing water sources to a large extent, resulting in the continuous reduction of available water resources. [0003] At present, domestic sewage generally adopts the following treatment methods: 1. Physical treatment; 2. Chemical treatment; 3. Biological treatment; 4. Anaerobic biological treatment; 5. Biological contact oxidation, etc. [0004] in; [0005] The physical treatment method is to separate and recover the insoluble and suspended pollutants in the wastewater through physical action; [0006] Chemical treatment is a w...
