Multistage biological contact oxidation reactor for sewage treatment

Abstract

The invention provides a multistage biological contact oxidation reactor for sewage treatment. The reactor comprises a conduit, a biological septic tank, a conditioning tank, a sludge tank, water inlets, a grille well, a multistage biological contact oxidation reactor main body and a manhole, wherein the water inlets are formed in the upper part of the biological septic tank, the upper part of the conditioning tank and the upper part of the sludge tank; and the biological septic tank is connected with the conditioning tank through the conduit. According to the reactor, through arranging the manhole, the detection on water quality is facilitated; through arranging an air blower, the running is stable, the air volume is large, the noise is low, the service life is long, maintenance is hardly required ordinarily, the air blower is made of aluminum alloy, the weight is light, and the servicing is very convenient; and through arranging bionic water filler, the adsorption capacity is extremely high, microbes are easily attached, the bionic water filler is appropriate for the growth of rich biological communities, and an ecosystem with a relatively long food chain made up of bacteria, algae, protozoa, metazoa and the like is formed, so that the reactor can be used for efficiently degrading organic pollutants and removing nitrogen and phosphorus.

Description

technical field [0001] The invention belongs to the technical field of reactors, in particular to a multipolar biological contact oxidation reactor used for sewage treatment. Background technique [0002] The biological contact oxidation process is an efficient biofilm sewage treatment technology commonly used in the world today, that is, a certain amount of filler is filled in the biological contact oxidation tank, and the sewage is in extensive contact with the biofilm, and the biofilm attached to the filler is fully utilized. The supplied oxygen, through microbial metabolism, oxidizes and decomposes the organic pollutants in the wastewater to achieve the purpose of purification. [0003] The existing multipolar biological contact oxidation reactor for sewage treatment has the problems of easy corrosion, difficulty in eliminating organic pollutants, nitrogen and phosphorus removal, and short service life. [0004] Therefore, it is very necessary to invent a multipolar bio...
