摘　　要：研究了新型低碳生物滴滤池处理餐饮废水的挂膜启动,及对餐饮废水处理的效果。结果表明:挂膜初期首先由于反应器中填料吸附作用,对餐饮废水中的CODCr和NH3-N的去除率都相对较高;中期在填料吸附饱和后,生物膜较少,对污染物利用不高而导致去除率急速下降;最后反应器对CODCr和NH3-N的去除率又重新升高,分别可以达到80%以上。表明挂膜启动成功,并且具有一定的抗冲击负荷能力。反应器对餐饮废水中的TN、TP也表现出良好的去除效果。低碳生物滴滤池处理餐饮废水无需动力就具有较好的去除能力,占地面积小,有较好的抗冲击负荷能力。The start-up process and the pollutants removal by a new low-carbon bio-trickling filter in the restaurant wastewater were studied.The results show that the removal ratios of CODCrand NH3-N at the very beginning were relatively high because of the media adsorption in the reactor.While at the mid-term the removal ratios were decreased rapidly since there was less membrane and the media adsorption was saturated.At last both removal rates of CODCrand NH3-N increased by above 80% respectively,and the bio-film was formed successfully.The reactor show a certain ability to resist pollutant load impact.The good removals of TN and TP in the wastewater were also get in the reactor.The low-carbon bio-trickling filter showed a strong pollutant removal ability without external power,less land occupation,and strong load resistance ability,so there are bright prospects for the use.
