Problems solved by technology

but cannot handle high concentrations of pollutants
[0007] The common defect of these three types of exhaust gas biological treatment equipment is that it is difficult to effectively remove the slow biodegradable substances due to the need to maintain a certain biomass and residence time for microbial degradation of pollutants
Using the method of increasing the volume of the equipment to prolong the residence time will bring problems such as large floor area, complex equipment, large investment,

Example Embodiment

[0031] Example 1:

[0032] See figure 1 .

[0033] The gas film-bioreactor waste gas treatment equipment made of plastic plates, its length, width, and height are respectively 30cm, 15cm, and 1200cm, including the bioreactor 11 and gas separator 5 with packing; Bioreactor 11, equipped with gas membrane module 13 (membrane area is 0.2-0.3m 2 ) Consists of a gas separator 5 and a dryer 6 containing desiccant;

[0034] An air inlet 2 is opened on the lower side wall of the bioreactor 11, and a perforated pipe 1 is installed at the air inlet 2. The other side wall of the lower part is provided with a water outlet 12, the air inlet 2 should be lower than the water outlet 12, the upper side wall is provided with a spray liquid inlet 9 and another perforated pipe 8 is provided at the inlet 9;

[0035] The inside of the bioreactor 11 is filled with fillers 10 such as sponge or perlite, and the other side wall of the upper part is provided with an air outlet pipe 7, which is connected to t...

Abstract

A gas film-type bioreactor system for treating waste gas is composed of a bioreactor, a gas separator, containing a gas film module and with concentrated gas flowing-back tube and gas outlet, and a drier. Said bioreactor containing filler in it has gas inlet, water outlet and gas outlet tube. Its advantage is through degradation of harmfull substance in waste gas.

Description

technical field [0001] The invention relates to the field of environmental protection technology, and belongs to equipment for treating exhaust gas by using a bioreactor, in particular to an air film-bioreactor exhaust gas treatment equipment. Background technique [0002] Pollutants in exhaust gas include organic pollutants and inorganic pollutants. It mainly comes from life and industrial production. Such as manure treatment, domestic garbage and food decay, petrochemical industry, livestock slaughtering and meat processing, aquatic product processing, oil industry, oil refining, coking, gas, fertilizer, pharmaceuticals, leather manufacturing, papermaking, synthetic materials, sewage treatment and garbage treatment and other industries. [0003] The biological treatment of waste gas is the process of using microorganisms to degrade or convert organic pollutants or odorous substances in waste gas into harmless or low-harm substances. Compared with other physical and chem...
