摘　　要：以城市污水为研究对象,研究了阶段运行历时、水力停留时间、溶解氧浓度及泥龄对一体化活性污泥法生物脱氮效果的影响,并对该工艺若干设计、运行的改良措施进行了讨论.试验结果表明,将系统控制在适宜的条件下,出水NH3—N可达到污水综合排放一级标准.Taking the urban wastewater as investigation objective,the influence of stepped operation time,hydraulic retention time (HRT),density of dissolved oxygen(DO),and sludge retention time (SRT) on the efficiency of biological nitrogen removal with integrated activated sludge processing was investigated and,then,several improving measures of the design and operation with this technique were discussed.Experimental result showed that,when the system is controlled to be in a suitable condition,the NH_3—N of output water could satisfy the standard of first-class for wastewater drainage.
