The invention provides a foul gas bio-physicochemical combination treatment system and method. The system comprises a twin-stage biological film unit, a biological activate carbon unit, a gas exhaustunit, a humidity conditioning unit and an intelligent control unit, wherein the twin-stage biological film unit receives foul gas, the foul gas enters a lower layer of biological filler where bacteriaare inoculated after the foul gas is uniformly distributed in an air inlet unit, part of pollutants in the foul gas are digested and absorbed, undigested pollutants enter an upper layer of biologicalfiller after being subjected to uniform gas distribution through a gas distribution plate, fungi and composite microorganisms are inoculated on the upper layer of filler, and a biological absorptionand biodegradation reaction occurs; and the residual foul gas received by the biological activate carbon unit is in contact with a honeycomb activate carbon assembly in the biological activate carbonunit, and the standard gas after being adsorbed and purified is connected with the air exhaust unit through an induced draft fan and then exhausted by reaching the standard. The system of the invention adopts the advanced high-efficiency bio-physicochemical combination treatment technique, and can efficiently, stably and rapidly treat the foul gas.
Description
technical field [0001] The invention relates to the technical field of malodorous gas treatment, in particular to a system and method for combined biological-physicochemical treatment of malodorous gas. Background technique [0002] In the process of sewage treatment, garbage transfer, garbage treatment and industrial and agricultural production, malodorous gases mainly composed of hydrogen sulfide, ammonia, mercaptans and volatile organic compounds will be produced. The composition of malodorous gas in these places is complex, the load fluctuates greatly, it is corrosive to equipment and pipelines, it will also interfere with normal industrial production and the daily life of surrounding residents, and cause harm to human health and the ecological environment. [0003] Conventional malodorous gas treatment technologies mainly include absorption, adsorption, photo-oxygen catalysis, incineration and plasma technology. However, due to the complex composition of malodorous gas...
