Sewage treatment plant odor collection and treatment system and method

Abstract

The invention discloses a sewage treatment plant odor collection and treatment system and method. The system comprises a gas collecting cover, a draft fan, a pretreatment spraying tower, a sterilization pool, a biological drip filtering tower, a centrifugal fan, an active carbon adsorption device and a regulating pool, wherein the gas collecting cover is arranged above a building pool body radiating odor, and is communicated with the lower part of a pretreatment spraying tower through the draft fan; the sterilization pool is communicated with the upper part of the pretreatment spraying tower;waste liquid discharged from the bottom of the pretreatment spraying tower flows back to the regulating pool through a pipeline; the lower part of the biological drip filtering tower is communicated with the top of the pretreatment spraying tower through a pipeline; odor subjected to pretreatment enters the biological drip filtering tower; a group of spray nozzles are arranged on the top of the biological drip filtering tower and downwards and intermittently spray nutrition liquid; the active carbon adsorption device is communicated with the top of the biological drip filtering tower through acentrifugal fan and is used for performing further treatment on the waste gas treated in the biological drip filtering tower and then discharging the waste gas in a standard reaching way. The investment is saved; the occupied area is small; the equipment is simple; the deodorization efficiency is high; the pollution bearing load is high; the operation cost is low.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a system and method for collecting and treating odor, in particular to a system and method for collecting and efficiently treating odor in a sewage treatment plant. Background technique [0002] With the development of social economy and industry, and the massive construction of urban sewage treatment plants, the problem of odor generated in the process of sewage treatment has become increasingly prominent, causing great distress and harm to the surrounding residents. The stench in the odor Substances will cause varying degrees of poisoning to the human body’s breathing, digestion, cardiovascular and nervous systems, and there is a hidden danger of causing cancer in the human body, which has attracted great attention from all walks of life and government departments. The requirements are increasing day by day, how to effectively control the malodorous gas has becom...

AI Technical Summary

Problems solved by technology

The biological filter covers a large area, the filler needs to be replaced regularly, and the deodorization process is not easy to control. It is generally used for biochemical degradation of malodorous gases and has wide applicability; the organisms in the biological scrubber are in a suspended state, the reaction conditions are easy to control, and the filler is not easy to block; but A lot of equipment, high cost, small specific surface area of ​​fillers, using the principle of biological adsorption and degradation, not suitable for slightly soluble compounds; biological trickling filter towers withstand high pollution loads and strong impact resistance, and are mostly used in the removal of high-concentration waste gas. Less used for low-concentration malodorous gas treatment
