Biology-atomization combined deodorization process and device for removing odor

Abstract

The invention relates to deodorization process and particularly relates to a biology-atomization combined deodorization process and device for removing odor. The process comprises the following steps: S1, carrying out biologic dripping-filter deodorization on the odor; S2, carrying out atomizing deodorization on the odor after being subjected to the biologic dripping-filter deodorization. The deodorization process and device have the beneficial effects that the most odor can be rapidly removed by utilizing a biologic method, and the investment cost of the biologic method is low; the rest odor is processed by utilizing an atomization method, the standing time of the odor is short, the usage amount of a chemical agent is little, and the operation cost is low. According to the deodorization process and device, the advantages of the biologic method and the atomization method are integrated and obvious advantages in investment cost and operation cost are achieved.

Description

technical field [0001] The invention relates to a deodorization process, in particular to a bio-spray combined deodorization process for deodorization and a device thereof. Background technique [0002] The odor of the sewage treatment plant mainly includes hydrogen sulfide and ammonia. The first-level standard for exhaust gas discharge at the factory boundary stipulated in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB 18918-2002) is ammonia 1.0 mg / m 3 , hydrogen sulfide 0.03 mg / m 3 . [0003] At present, the main treatment technologies are physical method, chemical method and biological method. Physical method refers to a method of masking, diluting or transferring odor by physical means without changing the essence of odorous substances. Common physical methods include dilution method, masking method, water washing method and adsorption method. The chemical method mainly uses the chemical medium to react with the odor, thereby changing the c...

AI Technical Summary

Problems solved by technology

[0004] There are certain limitations in the traditional deodorization process of sewage treatment plants. Among the physical methods, the dilution method and water washing method are difficult to treat odors up to the standard, and the investment and operation costs of the adsorption method are relatively high; among the chemical methods, the cost of the chemical absorption method is The energy consumption of the ozone oxidation method is relatively high, so the operating cost of the chemical method is relatively high

In the traditional biological method, hydrogen sulfide is rapidly degraded in the packing layer, and 10% of the packing layer can remove more than 90% of the hydrogen sulfide gas, but to meet the treatment standard, it is necessary to use 90% of the packing layer to remove the remaining About 10% hydrogen sulfide gas, high investment cost
