摘　　要：针对污水处理过程中的臭味，采用自然净化法进行了试验研究。结果表明：对于进水TON为18．2～33．3、CODcr为67-94mg／L的污水，当HRT≥4．5h时，TON去除率≥69．2％，出水TON≤8．0，该法对低有机浓度污水具有一定除臭效果；当进水TON为90．9～125．0、CODcr为408-1340mg／L时，TON去除率≥92．1％，出水TON≤8．0，该法对高有机浓度污水具有显著除臭效果。污泥中存在芽胞杆菌属，菌落数达到10^7数量级，且为优势属。Experiment on self-purification approach to eliminate odor in wastewater treatment were performed. The results indicated that, with the influent TON of 18.2-33.3 and CODcr of 67-94 mg/L, the TON removal rate reached beyond 69.2% and the effluent TON was no more than 8.0 （HRT≥4. 5 h）, this approach had positive effect on odor removal for organic wastewater with low concentration. While with the influent TON of 90. 9~ 125. 0 and CODcr of 408--1 340 rag/L, the TON removal rate reached beyond 92.1~, and effluent TON was no more than 8.0, this approach had a remarkable effect on odor removal for organic wastewater with high concentration. Also, Bacillus was found in the sludge with colony population reaching 107, and was dominant genera.
