【摘要】 位于居民生活区的城市污水处理厂的除臭问题,已是污水处理厂面临的突出问题。该文介绍了水清洗和药液清洗法、活性炭吸附法、臭氧氧化法、土壤脱臭法、填充式微生物脱臭法、燃烧法等6种除臭方法,并通过比较,指出微生物脱臭法是目前较为理想的方法。最后以广州市猎德污水处理厂投运的微生物脱臭法实例,H2S的去除率,由进气口的1-7mg／m3,到出气口只有0.003-0.009mg／m3。更多还原

【Abstract】 For urban sewage treatment plants located in residential districts, the deodorization is becoming a serious problem to face. Based on the introduction of six deodorization methods and comparisons, microbial deodorization method is recommended as a relatively ideal one at present. In the example of microbial deodorization in Guangzhou Liede Sewage Treatment Plant, the removing ratio of H2S has been decreased from 1-7 mg/m3 of inlet air to 0.003-0.009 mg/m3 of outlet air.更多还原
