摘要
利用厌氧池+人工湿地+人工浮床复合系统进行餐饮废水处理研究。结果表明,厌氧预处理对COD、TP的去除率分别为30.8%和30.3%,并把大分子有机物进行水解,提高人工湿地的处理效果;人工湿地是系统的主要处理单元,对COD、NH4+-N、TN平均去除率达到80%、90%7、0%以上,对TP的去除率在75%～90%之间波动;废水经后续人工浮床深处理后,出水水质能达农田灌溉水质标准GB5084-2005。人工湿地复合系统是处理餐饮废水一种可行的技术方法。
The combined system of anaerobic tank/constructed wetland/artificial floating rafts is applied to treat the restaurant wastewater.The results show：A pretreatment anit, anaerobic tank can remove 30.8% COD and 30.3% TP, it promote the effect of pollutant＇s removal in the constructed wetland by hydrolyzing macromolecule organic matter.Constructed wetland is the main unit in system,so the removal rates of COD,NH4＊-N and TN in it are above 85%,90%,70% ,respectively;The removing rates of TP is not stably,between 75% -90%.After artificial floating raft＇s treatment,the effluent quality can reach the requirement of standards of irrigation water quality （GB 5084--2005）.The constructed wetland system is a feasible technique for treatment of restaurant wastewater.
