摘要
针对已建污水处理厂的恶臭气体污染情况,对生化池、细格栅机和沉砂池进行加盖密闭后,选用生物滤池处理工艺对产生的恶臭气体进行处理,介绍了除臭系统工程设计、投资运行费用及日常运行管理的注意事项。工程实践表明,处理后排放的尾气中NH3、H2S和臭气浓度指标均达到《恶臭污染物排放标准》(GB 14554—93)的二级标准。
In order to control the odor pollution from a built wastewater treatment plant, biochemical tank, fine grid machine and grit chamber were covered, and malodorous gas was treated by biological aerated filter. The engineering design, investment and operating cost of deodorization system, and considerations for its daily operation management were introduced. The engineering practice showed that the concentrations of NH3 , H2S and odor of treated gas met the second class criteria specified in the Emission Standards for Odor Pollutants （ GB 14554 - 93 ）
