Abstract

The invention provides a biological treatment system for waste gas, which solves the problems of higher operating cost, complicated operation and low removal rate of a conventional waste gas desulfurization technology. The technology disclosed by the invention adopts higher pH, higher alkalinity and microbial resources of activated sludge of an aerobiotic system to spray and wash the waste gas, the deodorization efficiency and sulfuretted hydrogen removal rate are high, a washing liquid returns the aerobiotic system, sulfuretted hydrogen is converted into sulfate radical to be removed through a conventional aeration facility. The technology is simple to operate, low in operating cost and very suitable for waste gas treatment, and the efficiency is stable and guaranteed.

Description

technical field [0001] The invention relates to a novel waste gas biological treatment process, in particular to a waste gas biological scrubber. Background technique [0002] Exhaust gas treatment technologies in the prior art mostly adopt the following methods: [0003] The physical method is mainly to use activated carbon to adsorb, that is, to fill the activated carbon into the adsorption tower, and when the odor passes through the adsorption tower, the malodorous substances are adsorbed by the activated carbon. The adsorption method has good deodorizing effect, simple maintenance and stable operation. However, since activated carbon adsorption reaches saturation, it must be replaced or regenerated, the operating cost is relatively high, and the adsorption capacity of activated carbon is easily affected by moisture, dust and other impurities in the odor. [0004] The commonly used chemical method is the liquid absorption method, which uses solutions such as sodium hydr...
