强化生物絮凝+变速生物滤池复合工艺处理生活污水运行条件的确定
Optimum Operation Conditions of Enhanced Bio-flocculation plus Velocity-changed Bio-filter Process for Treatment of Sewage
【摘要】 进水温度低会导致污泥量小以及硝化、反硝化效果差。试验在低温条件下研究了缺氧/好氧强化生物絮凝+变速生物滤池处理宿舍区生活污水的效能,考察了缺氧/好氧池不同HRT之比对CODCr、NH3-N、TN、TP和浊度等污染物去除的影响,首次通过灰色系统理论来综合评判,从而确定在该试验条件下缺氧/好氧池最佳HRT之比为3.6∶2.4。
【Abstract】 Low temperature of the inlet wastewater has bad influence on nitrification and denitrification,and also causes small quantity of sludge.Full-scale experiment was conducted on treatment of swage by anoxic/oxic enhanced bio-flocculation plus velocity-changed bio-filter process,which has the purpose of investigating the performance of removal of CODCr,NH3-N,TN,TP and turbidity under different HRT ratios.The method of Grey System suggests that the optimal HRT ratio of anoxic/oxic is 3.6∶2.4 under the given conditions.
