Abstract

The invention provides an overturning plate type bio-membrane reactor, which is composed of a reactor shell, an overturning plate carrier area and an aeration area, wherein the overturning plate carrier area is arranged on the upper portion of the aeration area, the overturning plate carrier area consists of a plurality of groups of overturning plate carrier assemblies, microporous aeration heads are distributed in the aeration area, and a sludge outlet and a valve are arranged in the middle of the bottom of the aeration area to control sludge discharge. According to the invention, the carrier of the bio-membrane reactor is composed of a plurality of overturning plates, the overturning plate carrier can rotate, backwashing can be carried out from all angles, and the backwashing effect is good; reaction conditions such as dissolved oxygen concentration, sewage flowing and the like in the reactor can be controlled by rotating the overturning plate carrier, so that better reaction conditions can be easily achieved; and the surface of the overturning plate carrier is made of coral sand and waste cotton cloth, so that the biofilm forming effect is good, and the removal rate of pollutants in sewage is high.

Description

technical field [0001] The invention belongs to the technical field of water treatment and relates to a biofilm reactor, in particular to an overturned plate biofilm reactor. Background technique [0002] When the biofilm method is used to treat sewage, microorganisms accumulate and grow on the surface of the carrier to form a biofilm of a certain thickness, and the sewage is purified when it flows through the biofilm on the surface of the carrier. Compared with other biological treatment methods, the biofilm method has the following advantages: it has strong adaptability to environmental conditions; the microbial ecological structure in the biofilm method is complete, and the living conditions of the microorganisms are relatively stable. Therefore, the impact load on water quantity and quality Strong tolerance. The amount of sludge produced is small, the sludge settling performance is good, and compared with the activated sludge method, the biofilm method is less prone to ...
