Effect of aluminum sludge biological packing on nitrogen and phosphorus removal from black and odorous water
-
摘要: 现场小试模拟研究了铝污泥生物填料、聚丙烯纤维生物填料以及二者分别与狐尾藻组合在黑臭河道水体中的治理效果。结果表明:铝污泥生物填料能够调节水体pH,狐尾藻可提高水体溶解氧(DO)浓度,营造有利于微生物生长的微环境;铝污泥生物填料出水水质优于聚丙烯纤维生物填料,出水水质基本达到GB 3838—2002《地表水环境质量标准》Ⅴ类标准;铝污泥-狐尾藻组合对水体污染物的整体去除效果最好,出水水质优于GB 3838—2002的Ⅳ类标准,对CODCr、TP、TN和NH3-N去除率分别为74.62%、93.59%、93.19%和96.46%。Abstract: The treatment effect of combination of aluminum sludge, polypropylene fiber biological packing and foxtail algae in black and odorous water was simulated. The results showed that the aluminum sludge biological packing could regulate the pH of the water system, and the foxtail algae could improve the dissolved oxygen content, so as to create the micro-environment beneficial to the microorganisms. The effluent quality of aluminum sludge biological packing was better than that of polypropylene fiber biological packing, basically reaching Class Ⅴ standard of Environmental Quality Standards for Surface Water(GB 3838-2002). Especially, the combination of aluminum sludge biological packing and foxtail algae had the best overall removal effect on water pollutants, and the effluent quality was better than that of GB 3838-2002 Class Ⅳ standard. The removal rates of CODCr, TP, TN and NH3-N were 74.62%, 93.59%, 93.19% and 96.46%, respectively.
