Suspended media layer filtration system based on hydraulic fluid layer formation

Abstract

The invention relates to a suspended medium layer filtering system based on hydraulic fluid layering, belonging to the technical field of sewage treatment. The suspended medium layer filtering systemcomprises a filtering device, a reflux pump, a water inlet dosing system and a main body bracket. The filtering device is arranged on the main body bracket, and the main body bracket is arranged on the ground. The water inlet dosing system, the reflux pump and the filtering device form a circulation loop. According to the invention, a medium layer is adopted for filtering, a suspended medium layeris formed through hydraulic flow state, suspended impurities in sewage are effectively removed by utilizing the net catching and flocculation effects of the medium layer, the content of suspended substances in effluent is reduced, the effluent quality is improved, and the suspended medium layer filtering system has the characteristics of low energy consumption, low medicine consumption and convenient operation and maintenance.

Description

Technical field [0001] The invention relates to a suspending medium layer filtering system based on hydraulic fluid state stratification, in particular to a filtering system for treating secondary effluent of a sewage treatment plant or urban black and odorous water, belonging to the technical field of sewage treatment. Background technique [0002] At present, the secondary effluent treatment devices of sewage treatment plants designed and used at home and abroad are mainly used to further remove suspended solids, phosphates and other substances through coagulation sedimentation or direct filtration, so as to ensure the stable and up-to-standard effluent quality; for black and smelly water bodies The treatment is mainly through in-situ coagulation sedimentation or direct filtration to remove algae, suspended solids, phosphates and other substances in the water body to improve the black and odor phenomenon of the water body. With the improvement of my country's sewage treatment i...

AI Technical Summary

Problems solved by technology

With the improvement of my country's sewage treatment industry standards and the improvement of urban black and odorous water treatment requirements, the requirements for the removal of suspended solids, phosphate and algae in sewage have also increased. The existing coagulation sedimentation or direct filtration treatment methods have their own advantages. However, there is no filtration method and device for removing suspended solids, phosphate and algae in sewage through a suspension medium layer in the market at present.
