摘要
无机铝盐混凝剂处理采油废水的实验表明,PAC在最佳投药量即750mg/L时,COD、BOD5、SS和总P的去除率分别为64%、52.8%、91.5%和78.3%。Al2(SO4)3和PAM的投药量为750mg/L和1mg/L时,COD、BOD5、SS和总P的去除率分别为61.5%、40.9%、91.4%和75.3%。出水BOD5/COD由0.32提高至0.42,可生化性明显提高。
The inorganic aluminium salts coagulant was used to treat the petroleum produced wastewater （PPW）. The results of the experiment shows that when the dosage of PAC was 750 mg/l, the removal rate of COD, BOD5, SS and T-P were 64% 52. 8%, 91.5% and 78. 3%, respectively. When the dosage of Al2 （SO4）3 and PAM were 750mg/l and 1 mg/l, respectively, the removal rate of COD, BOD5, SS and T-P were 61.5%, 40. 9 %, 91.4% and 75.3 %, respectively. The BOD5/COD value of coagulation effluent increased from 0. 32 to 0. 42, i. e. , the biodegradability was improved.
