Waste gas treatment device and method by means of biological method

Abstract

The invention relates to a waste gas treatment device and method by means of a biological method. The method comprises a gas flowing system and a biological thallus circular treatment system. The gas flowing system comprises a gas collection port, a processor gas inlet pipeline, a draught fan, an exhaust port and a gas flowing pipeline. The biological thallus circular treatment system comprises a thallus culture box, a water pump, a biological processor and a circulating pipeline. The device and the method have the advantages that the biological technology does not cause secondary pollution and can be used for treating waste gas containing various pollutants; adaptability is high, and the device can work normally in a range high in odor concentration; treatment time is short, efficiency is high, and comprehensive efficiency can reach 95% or above; one-time biofilm culturing of thalli is achieved, the thalli are diversified, and inoculation time is short; chemicals do not need to be added, and operation cost is low; equipment is simple in structure, and manufacturing cost is low.

Description

technical field [0001] The invention relates to a device and method for waste gas treatment, in particular to a device and method for biological waste gas treatment. Background technique [0002] As the international environmental problems are becoming more and more serious, especially the environmental pollution caused by the discharge of waste water, waste gas and other harmful substances produced by the manufacturing industry is irreversible, which has caused serious harm to the earth's environment and human life. The need for decontamination has become particularly important. [0003] In my country, the conventional methods of waste gas treatment are as follows: [0004] Masking: A method of mixing malodorous gases into an overall scented and / or mildly scented odorous mixture. But this method cannot remove the poison. [0005] Air oxidation (combustion) method: aerobic combustion of exhaust gas to remove combustible substances and generate CO 2 、H 2 O et al. Howeve...
