Novel suspended moving bed sewage treatment integrated equipment and method

Abstract

The invention relates to novel suspended moving bed sewage treatment integrated equipment comprising a box body, wherein the interior of the box body is divided into an anaerobic zone, an anoxic zone,a first aerobic zone, a second aerobic zone, a coagulation zone, a sedimentation zone, a disinfection zone and a filtering zone which are sequentially communicated from front to back through partition plates; wherein filler layers are arranged in the anaerobic zone, the anoxic zone and the filter zone, each filler layer comprises a plurality of support plates and a filler, the plurality of support plates are horizontally arranged and are arranged at intervals up and down, and the filler is filled between two adjacent layers of support plates. According to the novel suspended moving bed sewagetreatment integrated equipment and method, the equipment is low in energy consumption, high in oxygenation capacity, good in nitrogen and phosphorus removal effect after long-term operation and easyand convenient to operate and maintain, and is sewage treatment combined process equipment with excellent performance.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a novel integrated equipment and method for sewage treatment with a suspended moving bed. Background technique [0002] Compared with decentralized sewage treatment in recent years, integrated sewage treatment devices have been widely used because of their convenient installation, high degree of automation, and small footprint. Commonly used technology is A 2 / O, biological contact oxidation, MBR, SBR, constructed wetlands, etc. During long-term operation, such systems have limited removal effects on nitrogen and phosphorus, and the effluent cannot meet the standards stably. Among them, land infiltration and constructed wetlands and other processes can use phosphorus removal fillers to improve the phosphorus removal effect of the system, but this causes problems such as replacement, regeneration and reuse of fillers after adsorption saturation. The effluent water quali...

AI Technical Summary

Problems solved by technology

Commonly used technology is A 2 / O, biological contact oxidation, MBR, SBR, constructed wetland, etc. During long-term operation, such systems have limited removal effects on nitrogen and phosphorus, and the effluent cannot meet the standards stably

Among them, land infiltration and artificial wetlands and other processes can use phosphorus removal fillers to improve the phosphorus removal effect of the system, but this has caused problems such as replacement, regeneration and reuse of fillers after adsorption saturation.

MBR effluent water quality is good, but the operation and maintenance is complicated, often due to membrane fouling, resulting in insufficient water production, unable to meet production standards
