Integrated autotrophic denitrification reactor

Abstract

The invention discloses an integrated autotrophic denitrification reactor. The reactor comprises a reactor main body, a base and a support installed on the base. The reactor main body and the support are installed on the base. The reactor main body comprises an upper biological rotating disc and a lower anaerobic ammonia oxidation unit. The biological rotating disc comprises a water tank, a rotating disc, a rotation center shaft and an aeration device. The inner cavity of the anaerobic ammonia oxidation unit is orderly divided into a first reaction zone, a second reaction zone and a third reaction zone. The third reaction zone is orderly divided into a granular sludge zone, a settling zone and an outlet water zone from top to bottom. The bottom of the granular sludge zone is provided with a sludge discharge outlet with a valve. The upper part of the outlet water zone is provided with a downflow weir. The outer part of the downflow weir is provided with an outlet water groove. The bottom of the outlet water groove is provided with an outlet water pipe. According to the biological rotating disc-anaerobic ammonia oxidation combined reactor, in the air-driven biological rotating disc, through rotating disc rotation, high-nitrogen content waste water and oxygen fully contact so that shortcut nitrification is realized. Through adjustment of an aeration rate, a rotating disk rotating rate can be controlled. The reactor has good impact load resistance.

Description

technical field [0001] The invention relates to an integrated autotrophic denitrification reactor. Background technique [0002] In the 1970s, my country began to conduct research on biological turntables, which were applied in the treatment of industrial wastewater in printing and dyeing, papermaking, leather and petrochemical industries, and achieved good results. In terms of process operation and maintenance, the biological turntable has the advantages of low power consumption, strong impact load resistance, no need to return sludge, and convenient management and operation. However, the traditional biological turntable has problems such as low organic load and poor denitrification effect in sewage treatment. [0003] The biological turntable / ANAMMOX process is a green and efficient biological denitrification process. The process performs short-range nitrification in the biological turntable stage, followed by anaerobic ammonium oxidation, and realizes the biological trea...
