Biological deodorization filtration column and biological deodorization method

Abstract

The invention provides a biological deodorization filtration column and a biological deodorization method. The biological deodorization filtration column comprises an upper structure, a cylinder and a lower structure, wherein the upper structure consists of a cover plate, a feeding device, a gas exhaust unit and a sprinkler; the lower structure consists of a gas distribution device and a discharging device; waste gas enters the biological deodorization column from the gas distribution device, and gas reaching the standards is discharged after purification processing; necessary water is provided by the sprinkler for biodegradation and metabolism, and an out-material delivery device and an in-material delivery device are started and run under the control of control equipment according to the detection result of a sensor; the sprinkling time and the flow rate of the sprinkler are controlled; and a temperature in the biological deodorization filtration process is controlled through the regulation of the temperatures of sprinkled liquid and the waste gas. The biological deodorization filtration column and the biological deodorization method have the advantages of high efficiency, safety in use, low cost, convenience in filter material change and addition, reduction in worker cost and freedom of any secondary pollution.

Description

Technical field [0001] The invention belongs to the field of environmental protection, and specifically relates to a waste gas biological treatment equipment capable of automatically replacing and adding filter materials, which is applied to the biological treatment of waste gas. Background technique [0002] In the process of industrial and agricultural production, sewage treatment, garbage treatment, etc., a large amount of waste gas will be generated, which not only pollutes the surrounding environment, but also causes serious harm to human health and the ecological environment. Waste gas treatment has attracted more and more attention. [0003] Exhaust gas treatment technologies include absorption and adsorption, incineration, condensation, and biological methods. Biological treatment of exhaust gas is a process of using microorganisms to degrade or convert organic pollutants or malodorous substances in exhaust gas into harmless or low-hazard substances. Compared with other tr...
