A kind of asbr-sbr-asbr combined reaction device

Abstract

An ASBR-SBR-ASBR combined reaction device belongs to the field of sewage biological treatment technology, which can solve the problems of difficult independent regulation of the existing ammonia nitrogen removal process, long reaction time, poor load resistance, easy accumulation of nitrate, high energy consumption, and micro-oxygen exposure. Under atmospheric conditions, it is difficult to completely mix mud and water, DO is difficult to control stably, the output is unstable, and the degree of automation of the reactor is not high, including online controllers, diverters, aeration pumps, water storage tanks, A-section ASBR reactors, and B-stage reactors. Section SBR reactor and C section ASBR reactor, A section and C section are equipped with gas collection devices; when the mechanical rotating shaft rotates, it drives the microporous aeration tube at the bottom of the pool to rotate together, which can improve the utilization rate of oxygen and make the muddy water The mixing is more complete, the reaction time is reduced, the operating cost of the reactor is saved, and the foundation is laid for the next step of the anammox reaction. The device realizes automatic monitoring of the reactor, and keeps various parameters in the reactor stable.

Description

technical field [0001] The invention belongs to the technical field of sewage biological treatment, and specifically relates to a control technology for wastewater containing organic matter and ammonia nitrogen, which is suitable for the adsorption of wastewater containing high organic matter, low carbon sources, and high ammonia nitrogen and the combined ASBR-SBR-ASBR process control of semi-short-range nitrification process. Reactor. Background technique [0002] With the rapid development of my country's large-scale livestock and poultry breeding industry, large-scale livestock and poultry farm wastewater has become the main source of pollution in many areas of our country. This type of wastewater has the characteristics of high organic matter content and high ammonia nitrogen content. If livestock and poultry wastewater is not properly treated, it will seriously pollute water, soil and air. The massive discharge of livestock and poultry wastewater will also pose a huge...
