Efficient energy-saving sewage treatment system

Abstract

The invention discloses an efficient energy-saving sewage treatment system. Sediments are introduced into precipitates obtained after introducing sewage into a reaction pool again for secondary precipitation; precipitates passing through a multilayer filter pool are treated and precipitated again through being respectively introduced into a biological oxidization pool or a reaction pool according to the mesh number; through the multi-time circulation treatment on the sediments, the work efficiency of the sewage treatment system is greatly improved; the sewage treatment effect is good. A plurality of rotating spray heads are arranged on the reaction pool, so that a water purification agent in the reaction pool can sufficiently and effectively take a reaction with sewage so as to remove suspended matters and colloid pollutants; porous ball-shaped suspension filling materials arranged in the precipitation pool and the multilayer filter pool are matched with grilles at sewage inlet and outlets of each treatment pool; the sewage treatment effect is greatly improved; the sewage treatment time is greatly reduced. The efficient energy-saving sewage treatment system is particularly applicable to small and medium-sized enterprises; the steps are simple; the cost is low; good economic benefits and environment benefits are realized.

Description

technical field [0001] The invention relates to sewage treatment, in particular to a high-efficiency and energy-saving sewage treatment system. Background technique [0002] At present, the treatment methods for water pollution are mainly chemical treatment methods, that is, water pollutants are treated by adding drugs. Due to the variety of water pollutants and mixed, and the existing water treatment agents have a single function, they are separately put into the sewage treatment system. Adding flocculants, corrosion inhibitors, fungicides and other agents, the treatment process is complex, and especially for industrial sewage, the types are more and more complex, the components are complex, and the treatment is relatively difficult, often requiring large-scale treatment equipment, while small For factories or families, the existing sewage treatment equipment occupies a huge area, the equipment is complex, the treatment time is too long and the treatment effect is not good....

AI Technical Summary

Problems solved by technology

[0002] At present, the treatment methods for water pollution are mainly chemical treatment methods, that is, water pollutants are treated by injecting drugs. Since there are many types and mixed types of water pollutants, and the existing water treatment agents have a single function, they are separately injected into the sewage treatment system. Add flocculants, corrosion inhibitors, bactericides and other agents, and the treatment process is complex, especially for industrial sewage, with more types and complex components, and relatively difficult treatment, often requiring large-scale treatment equipment, while small For factories or households, the existing sewage treatment equipment occupies a large area, the equipment is complicated, the treatment time is too long and the treatment effect is not good, etc.

[0003] Existing sewage treatment methods also include biochemical methods, but biochemical methods have huge investment and high operating costs, which are unaffordable for small and medium-sized enterprises, and most of the sewage treatment effects are not good. Only by meeting the discharge standards, renewable resources cannot be realized
