厌氧-好氧活性污泥法(A/O)-体化装置处理生活污水的中试研究
Pilot-scale test on domestic waste water treatment using integrative A/O (anaerobic-aerobic sludge) equipment
摘要
Abstract
An integrated A/O(anaerobic-aerobic sludge) equipment was designed based on the principle of A/O process and the treatment effect on domestic wastewater by the reactor was studied in pilot scale. The treatment efficiency of domestic wastewater was investigated under the conditions of influent rate of 1 m3/h, reflux ratio of 200%, total HRT (hydroli retention time) of 5-8 h and water temperature of 4-14 ℃.The results show that the equipment can operate steadily after two weeks operation. When TP, TN, NH/-N, CODCT and BOD5 of influent are 4.2-12.9, 40.0-80.0, 5.4-30.7, 161.3-441.4 and 43.0-196.0 mg/L, respectively, the average removal efficiencies of TP, TN, NH/'N, CODct and BOD5 are 86.7%, 69.5%, 80.0%, 84.7% and 84.9%, respectively. The effluent can come up to the second level standard of "discharge standard of pollutants for municipal wastewater treatment plant" (GB 18918-2002). As compared with the traditional sewage treatment technologies, it has advantages of less land occupation, easy management and high capacity of resisting impact load.关键词
