摘要
为研究序批式IAL-CHS反应器处理去除总磷(TP)和氨氮的特性,用模拟废水进行小试研究。试验结果表明:进水氨氮为12.35～20.22mg/L,出水氨氮为0.79～9.52mg/L,去除率为41.85%～96.09%,平均去除率为76.3%;进水TP为1.89～3.33mg/L,出水TP为1.55～3.12mg/L,去除率为3.05%～24.32%,平均去除率为11.31%;该生物反应器具有良好的耐氨氮冲击负荷能力,而且丝状菌大量繁殖对氨氮和TP去除率的影响不明显。
To study the characteristics of total phosphorus （TP） and ammonium removal by sequencing batch IAL-CHS reactor（Internal Airlift Loop Ceramic Honeycomb Support reactor, simple name： IAL-CHS reactor）. Lab-scale experiment was operated by using simulate wastewater. The experiment results show that the concentration of ammonium in the influent reaches 12.35-20.33 mg/L, ammonium in the effluent of 0.79-9.52 mg/L, and the removal rate reaches 41.85%-96.09% and the average removal rate reaches 76.3%, the concentration of TP in the influent reaches 1.89-3.33 mg/L, TP in the effluent of 1.55-3.12 mg/L, and the removal rate reaches only 3.05%-24.32% and the average removal rate reaches 11.31%. The bioreactor has excellent resistance shock loading ability of ammonium. Moreover, overgrow filamentous bacteria has not influence obviously to the removal rate of ammonium and TP.
