Embodiment Construction

[0021] Such as figure 1 The waste gas treatment system shown in the waste water has a basically sealed top cover at the opening of the sewage container 1, and a waste gas outlet is provided on the top cover. Behind the waste gas outlet, the waste gas first flows through the waste gas pretreatment device 2, and then enters the The biological treatment device 4 has a biological bed filler and microorganisms 3 inside; the microbial material is a microbial strain that can absorb and use various organic waste gases as nutrients, and can absorb or degrade part of the organic gas; then, enter the adsorption device 10, It has adsorption filler inside to absorb some harmful gases in the remaining waste gas; the adsorption filler can absorb part of the organic waste gas and part of the inorganic waste gas in the waste gas.

[0022] After the biological treatment device 4 and before the adsorption device 10, a mist removal device is connected to remove water vapor in the waste gas.

Abstract

The invention discloses a treatment system for waste gas escaped from wastewater. The treatment system is used for collecting and treating waste gas released from a sewage container of a sewage treatment plant. A basically sealed top cover is arranged at the opening of the sewage container, and a waste gas outlet is formed in the top cover. A pretreatment device, a biological treatment device and an adsorption device are sequentially arranged behind a waste gas outlet, and finally produced waste liquid is recycled or flows into a sewage treatment plant. The concentration of waste gas in a later wastewater treatment pipeline is lower, and the investment cost of later wastewater treatment equipment is reduced.

Description

technical field [0001] This application is a divisional application of a patent application with the application number 2016109879475 and the name "Treatment System for Escaping Waste Gas from Wastewater". The present invention relates to treatment equipment for waste gas in sewage pools or sewage. Background technique [0002] The waste water sent to the sewage treatment plant or the waste water during the sewage treatment process often emits waste gas into the air, and the waste gas often has an unpleasant smell. Traditional wastewater treatment only purifies liquid wastewater, and basically does not treat the exhaust gas escaping into the air or the treatment effect is not ideal. [0003] The patent application number is 2012103675438, which provides a new method for collecting and treating waste gas from sewage treatment plants. By sealing the tank body where waste gas is produced in the sewage treatment plant, the waste gas produced is transported to the ozone generato...
