摘要
研究了高效好氧生物反应器(HCR)系统处理高浓度氨氮有机废水的可行性,对影响系统处理效果的因素进行了分析和探讨。结果表明:当进水中氨氮为2 000～2 200 mg/L、COD 500～9 000 mg/L、pH 9.5～10.0,系统反应的水力停留时间7.0～7.5 h时,氨氮去除率最高达到72%以上,氨氮容积负荷最高达到4.8 kg/(m3.d)以上,COD容积负荷最高达到21.6 kg/(m3.d)。说明HCR系统预处理高浓度氨氮有机废水可行。
The feasibility of treating the highly concentrated ammonia-nitrogen organic wastewater with HCR system has been studied,and the influential factors of the system are analyzed and discussed. It shows that when the concentration of the ammonia-nitrogen of influent water is in the range of 2 000-2 200 mg/L,the concentration of COD is 500-9 000 mg/L,the pH is 9.5- 10.0,the hydraulic retention time is 7.0-7.5 h,the ammonia-nitrogen removal rate would be up to 72% ,the highest NH3-N 1 to 21.6 kg/（m^3.d）. It is feasible to pretreat the highly system. oading rate is over 4.8 kg/（m^3.d）,the COD loading rate is up concentrated ammonia-nitrogen organic wastewater with HCR
