摘要
采用植物提取液进行污水处理厂除臭。简要介绍了植物提取液除臭的机理:利用喷雾系统将提取液直接喷洒在臭气源附近,喷洒剂中的活性成分可使异味分子发生化学反应,从而达到除臭的目的。污水处理工程污水量5万m3/d,分成四个相对独立的控制区域,总控制面积2 500 m2。工程总投资200.5万元,运行费用9 773元/d。系统运行时,H2S和NH3均能达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)二级标准。
Plant extracts were applied for deodorization in wastewater treatment plant（WTP）. The mechanism of this process was presented briefly. In practice the extracts were sprayed directly around the area where the smell emitted, by this way the malodorous molecules react with the activated constituents in the sprayed agents and so the goal of deodorization has been gained. For this project of WTP with capacity of 5×10^4 m^3/d, four control zone were divided with total control area of 2 500m^2, total capital of RMB 2. 005 million was invested for construction and the daily operating expense will be RMB 9 773. This facility has been put into normal operation, the removals of both H2S and NH3 could be meet the requirement of class II of the Discharge standard of pollutans for municipal wastewater treatment plant （GB 18918-2002）.
