Abstract

The invention belongs to the technical field of waste gas treatment, and in particular relates to a waste gas deodorization device. Odorous gas collected by an odorous gas collection system passes through a waste gas draught fan to reach a gas inlet air pipe located between a first biological filtering device and a liquid collection groove, and then enters a tower body; the odorous gas is raised upward and passes through the first biological filtering device to reach a chamber formed between the first biological filtering device and a second biological filtering device; the odorous gas is deodorized through activated sludge water mist sprayed out by a first activated sludge spraying device; then the residual odorous gas is raised upward and enters a chamber formed between a spraying pump and the second biological filtering device; the spraying pump, a recycled water spraying device and a second activated sludge spraying device are used for spraying out water mist, high-alkalinity secondary sedimentation recycled water mist and activated sludge water mist respectively to carry out deodorization on the odorous gas; the odorous gas is treated to obtain purified gas which is dischargedthrough an exhausting opening. A solution obtained at the bottom of the tower body reaches an overflowing groove through a communication hole, and the solution in the overflowing groove passes through an overflowing pipe to reach an aerobic treatment system and then is treated.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a waste gas deodorization device. Background technique [0002] With the continuous improvement of national environmental protection monitoring and the continuous enhancement of corporate environmental protection awareness, in order to avoid the impact of the odor generated by the waste gas treatment system on the environment and surrounding residents during the production process, the sewage treatment plant needs to conduct odor control during production and operation. Collection processing. [0003] Biological deodorization is a kind of malodorous waste gas treatment technology commonly used in sewage plants at present. It has the advantages of good treatment effect and no secondary pollution. However, the current biological deodorization systems used to treat malodorous waste gas in sewage all have high chemical and water consumption in the spraying pr...
