External immersed electrocatalysis anaerobic membrane bioreactor

Abstract

The invention discloses an external immersed electrocatalysis anaerobic membrane bioreactor. The immersed electrocatalysis anaerobic membrane bioreactor comprises a water inlet tank, a suction pump a,a UASB reactor, a gas storage tank, a suction pump b, a membrane treatment device, a suction pump c, an air pump and a water outlet tank, wherein the water inlet tank is connected to a water inlet ofthe UASB reactor through the suction pump a; a water outlet of the UASB reactor is connected to a water inlet of the membrane treatment device through the suction pump b; the membrane treatment device is connected to the water outlet tank through the suction pump c; the gas storage tank is connected with the top of the UASB reactor and the air pump; the air pump is also connected with the membrane treatment device. The external immersed electrocatalysis anaerobic membrane bioreactor is provided with foamed silicon carbide filler, an electrode device, a membrane device and the like, so that use ratio of organic matters in sludge is increased, and reaction efficiency and pollutant removing rate are effectively improved.

Description

technical field [0001] The invention relates to a biological reaction device, in particular to an external submerged electrocatalytic anaerobic membrane biological reaction device. Background technique [0002] In recent years, with the rapid development of pharmaceutical, printing and dyeing and chemical industries, the types and quantities of artificially synthesized organic substances are increasing day by day, followed by the generation of a large number of refractory organic pollutants. Major pharmaceutical factories, printing and dyeing factories, and chemical factories across the country have newly built or expanded to increase production to meet market demand. These factories discharge a large amount of organic wastewater in the production process. Once discharged directly, it will not only cause serious pollution to the surrounding environment, but also It will cause serious harm to human health and the ecological environment. Industrial wastewater such as pharmace...

Problems solved by technology

The process structure is simple, the water distribution effect is good, and the packing frame structure is stable, but there are also some shortcomings: ①The reactor has strict requirements on parameter control, and it is difficult to ensure that the microorganisms in the granular sludge react under their optimal conditions; ②The reaction device is simple , the treatment method is single, it is difficult to guarantee a high removal rate of organic wastewater

A common strategy to solve this problem is to add additional electronic substrates (such as lactate, glucose, and ethanol), but this undoubtedly increases the operating cost
