UBF anaerobic reactor based on biochar carrier

Abstract

The invention discloses a UBF anaerobic reactor based on a biochar carrier. The UBF anaerobic reactor comprises a reaction tank, a biological filler layer is arranged on the upper portion of the reaction tank, a water inlet pipe is arranged on one side of the reaction tank, a sludge discharge pipe is arranged on the other side of the reaction tank, and the sludge discharge pipe, a water distributor, a granular sludge layer, the biological filler layer, an effluent weir and a gas collection port are sequentially arranged on the reaction tank from bottom to top. The anaerobic digestion capability of anaerobic microorganisms on sewage is improved through the biochar, and the anaerobic microorganisms in the reaction tank mainly exist in a biological membrane on the surface of a filter material through the biological filler layer, so that the quantity and activity of the microorganisms in the reaction tank are improved; according to the invention, the sewage treatment capability, the pollutant load impact resistance and the stability of a traditional UBF anaerobic reactor are improved, and the UBF anaerobic reactor has the characteristics of simplicity in operation, high treatment efficiency and the like.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to a UBF anaerobic reaction based on a biochar carrier. Background technique [0002] Conventional anaerobic reactors have always had the problem of microorganisms being lost along with the effluent. For this reason, such as USAB, a three-phase separator is installed on the upper part of the reactor, but the three-phase separator generally has the disadvantage of low efficiency of gas, liquid and solid three-phase separation. , The MBR reactor uses membrane separation technology to intercept microorganisms, and uses biofilm as the medium to obtain a high amount of activated sludge in the reactor, but usually causes biofilm pollution, affects the biological performance of the membrane, and makes the physical permeability of the membrane Changes occur, the proper filtration effect cannot be achieved, and it takes manpower and material resources to clean the biofilm regul...

Problems solved by technology

[0003] In this regard, how to solve the problems of the existing anaerobic reactor with few microorganisms, low processing load and poor load impact resistance is the problem to be solved by the present invention

[0004] The purpose of the present invention is to overcome the problems of the current anaerobic reactor with the loss of microorganisms with the effluent, low anaerobic digestion capacity, poor load impact resistance, and membrane fouling, and to invent a UBF anaerobic reactor based on a biochar carrier. The overall structure is simple, using biochar as the carrier of microbial reaction, through the biochar carrier and biochar filler layer, the microorganisms are adsorbed and intercepted, and the number and activity of microorganisms in the reactor are improved. , avoiding the phenomenon of "short flow" and "dead zone" in the influent, realizing the full contact between microorganisms and sewage, which is conducive to biochemical reactions, and improves the anaerobic digestion capacity of the reactor for sewage
