Foul gas deodorization process for brewery sewage treatment plant

Abstract

The invention discloses a foul gas deodorization process for a brewery sewage treatment plant. The foul gas deodorization process comprises an active soil filter bed, a gas-liquid separation layer anda biological deodorization filter tank, wherein the gas-liquid separation layer is arranged above the biological deodorization filter tank; one side of the gas-liquid separation layer is connected with a gas feeding pipe; a humidifier is mounted in the middle of the gas feeding pipe; a fan is arranged at one end of the gas feeding pipe; a cleaning pipe is mounted above the gas-liquid separation layer; a gas distribution device is arranged above the cleaning pipe; the active soil filter bed is arranged above the gas distribution device; the active soil filter bed is filled with a volcanic cushion layer, an active soil filler layer and a humus filler layer in sequence; a spraying pipe is mounted on the active soil filter bed; the top of the spraying pipe is connected with an exhaust pipe; one side of the biological deodorization filter tank is communicated with a liquid discharging pipe; a valve is fixed on the liquid discharging pipe; the other side of the biological deodorization filter tank is communicated with a biological nutrient solution through the valve. The foul gas deodorization process for the brewery sewage treatment plant is high in deodorization efficiency, mature instructural design, and very suitable for treatment of strong odor and a foul environment.

Description

technical field [0001] The invention relates to a gas deodorization process, in particular to a malodorous gas deodorization process of a brewery sewage treatment plant. Background technique [0002] Odor gas pollution refers to all gaseous substances that stimulate the olfactory organs to cause people's unpleasantness and damage the living environment. With the enhancement of people's awareness of environmental protection, the requirements for environmental quality are getting higher and higher, and they are becoming more and more sensitive to odor pollution. Odor pollution has become one of the seven major environmental hazards in the world. The malodorous gases mainly include hydrogen sulfide, ammonia, mercaptans, sulfides, and benzene series. Existing deodorization processes mainly include physical methods, ion methods, chemical methods, and biological methods. Due to the characteristics of low investment cost, low operating cost, stable treatment effect, simple proce...

AI Technical Summary

Problems solved by technology

The traditional biological soil method needs to increase the height of the packing layer for the occasions where the concentration of hydrogen sulfide, ammonia and other components in the odor is high, which correspondingly increases the investment cost and the operation resistance of the device
