摘　　要：针对污水处理厂优化运行及节能降耗的需求,以广州市某污水处理厂为研究对象,对其生化池进水COD和氮素进行了ASM2D模型的组分分析。分析结果显示:该厂进水中,生物降解有机物(Ss+Xs)和异养菌X_H仅占总COD(COD_T)的25.11%和16.74%,而溶解性不可生物降解有机物S_I、颗粒态惰性有机物X_I分别占COD_T的8.92%、49.23%,进水可生化性较差,后期泥水分离的效果直接决定了总COD的去除率。试验同时对该厂的异养菌产率系数Y_H进行了检测。Aiming at the optimized operation,energy-saving and consumption reducing of the wastewater treatment plant(WWTP),influent COD and nitrogen of a Guangzhou WWTP was analyzed which was based on ASM2 D.Biodegradable organic matter(Ss +Xs)and heterotrophic biomass(XH)may be only 25.1% and 16.74% of influent by total COD(COD_T)component analysis,the ratios of soluble inert substrate(S_I)and particulate inert substrate(X_I)to total COD were 8.92% and 49.23%,respectively,which meant that influent seemed to be poor biodegradability.As a result,the efficiency of separation between water and slurry had great influence on the removal rate of COD_T.In addition,the heterotrophic yield coefficient(Y_H)of the improved AAO process in wastewater treatment plant had been measured.
