重庆大型污水处理厂除臭工程应用案例

Application Case of Deodorization Project in Large WWTP in Chongqing

重庆鸡冠石污水处理厂为重庆市规模最大的污水处理厂。厂中臭气性质复杂,布局分散,缺少针对性的除臭装置,对周边环境造成了不利影响。改造工程采取系统性理念,通过组合加盖模式进行臭气收集、等距同程风管进行输送、高效除臭工艺灵活应用,结合多种创新手段精准施策,实现优于预期的除臭目标。除臭改造工程自投入运行以来,产生的臭气经处理后均实现达标排放,即满足《恶臭污染物排放标准》(GB 14554—1993)二级标准,恶臭源得到有效控制,除臭效果显著,为大型污水处理厂除臭设计提供了很好的借鉴。

Chongqing Jiguanshi wastewater treatment plant(WWTP)is the largest WWTP in Chongqing City.Odor in this WWTP is complex and dispersed.And this WWTP is lack of specific deodorizing device,which has a negative effect on the surrounding environment.The transformation project adopts the systematic idea,through the combination of covering mode for odor collection,the same distance air duct for transportation,and the flexible application of high efficiency deodorization technology,combining with various innovative means and precise measures,which achieves better than expected deodorization goals.Since the deodorization project has been put into operation,all the odors produced have been treated and meet the second class criteria of Emission Standards for Odor Pollutants(GB 14554—1993),the odor sources have been effectively controlled,and the deodorization effect is remarkable.It provides a good reference for deodorization design of large WWTPs.
