Self-aerated biofilm reactor and sewage treatment system applying same

Abstract

The invention discloses a self-aerated biofilm reactor and a sewage treatment system applying the same. The self-aerated biofilm reactor comprises circular ring-shaped disk sheets; a plurality of disk sheets are laminated and fixed together through fixing rods; cylinder structures are hermetically formed by blind plates at two ends of each disk sheet; support frames are fixed on the blind plates at two ends of the disk sheet, and are connected through a central rotating shaft; and an adsorption material is filled and fixed in the hollow portion of each cylinder. The self-aerated biofilm reactor can be mutually combined with a plurality of sewage treatment devices to improve the sewage treatment efficiency. The invention provides the self-aerated biofilm reactor and the sewage treatment system adopting the self-aerated biofilm reactor, is more economical in sewage treatment, saves the resources, and is high in treatment effect.

Description

technical field [0001] The invention relates to the technical equipment field of comprehensive sewage treatment, in particular to a self-aeration biofilm reactor and a sewage treatment system using the reactor. Background technique [0002] At present, the sewage treatment process is basically primary treatment (also called pretreatment), secondary treatment, effluent or water effluent or reuse after advanced treatment. Generally, primary treatment includes grille, grit chamber, and primary sedimentation tank; secondary treatment mainly adopts biological treatment, both anaerobic and aerobic, and activated sludge method is commonly used for domestic sewage. Advanced treatment generally includes biofilm method, filter cloth filter, etc. [0003] The primary sedimentation tank is the main treatment structure of the primary sewage treatment plant, or as a pretreatment structure of the secondary sewage treatment plant, mainly to remove suspended substances in the water. The se...

AI Technical Summary

Problems solved by technology

It is composed of a self-aeration biological turntable and an adsorption material filled in the self-aeration biological turntable. On the aerated biofilm reactor, microorganisms with a long survival time can be grown for generations, the sludge age is long, and it has a long durability. Shock load capacity, good treatment effect, high microbial concentration in process and maintenance operation, no need for reflux of sludge, low power consumption, low operating cost, etc. Facing problems such as bad odor, low organic load, uncompact structure, complex construction, large floor area, and large load of the central rotating spindle
