Abstract

The invention provides a deodorization method for a biological filter. The deodorization method comprises the following steps: (1) screening deodorization microbial strains aiming at NH3 and H2S; (2)using the deodorization microbial strains aiming at NH3 and H2S to prepare a high-concentration bacterial solution; (3) inoculating the high-concentration bacterial liquid into a mixed filler packed in a biological filter; and (4) conducting biofilm culturing. The deodorization method can effectively solve the problems of blockage and poor air permeability of the filler in the use process, and deodorization dominant bacteria are inoculated on the filler to improve the deodorization effect.

Description

technical field [0001] The invention relates to the technical field of biological treatment of odor, in particular to a deodorization method for a biological filter. Background technique [0002] Urban sewage plants undertake important responsibilities such as sewage purification, water quality improvement, and water pollution prevention. However, the influent water of sewage plants contains a large amount of organic substances. Composition NH 3 、H 2 S and other special odorous substances are unpleasant to the senses and even endanger human health. With the continuous advancement of urban construction, the distance between the built or newly built sewage plants and densely populated residential areas is getting closer and closer, and the environmental and social problems caused by the stench of sewage plants are becoming more and more serious. At present, the deodorization methods of sewage plants mainly include physical and chemical methods and biological methods. In re...
