摘要
利用自制的高效廉价混凝剂 ,结合仿生膜生物反应器技术对印染废水的处理进行了研究。试验得到 :混凝后 CODCr的去除率平均达 75 .1%,色度分别从 12 5 0倍和 3 90倍降为 3 0倍和 12倍 ,透过率达到 84.6%和 86.2 %,浊度在 10度以下。再经仿生膜生物反应器处理 ,出水 CODCr低于 5 0 mg/ L,CODCr去除率为 96.2 %,出水无色无味 。
High efficient and cheap complex coagulants, integrated with a bio\|mimic membranebio\|reactor were used to treat printing and dyeing wastewater. The promising experimental results were obtained and showed as following: the average removal of COD Cr was 75.1% after coagulation, and color decreased from 1250 and 390 to 30 and 13 respectively. Moreover, transmittance of effluent reach 84.6% and 86 2% with turbidity below 10 degrees. The effluent of coagulation was further treated by a bio\|mimic membrane bio\|reactor. The COD Cr of final effluent was below 50 mg/L with high COD Cr r emoval of 96.2%, and the effluent without color and taste met the need of the standard of some reused water.
