摘要:
 采用Al2(SO4)3和Ca(OH)2组合絮凝体系联合曝气生物滤池（BAF）对麦草生物化学机械浆（Bio-CMP）制浆废水进行了处理。首先分析了其絮凝机理及影响絮凝效果的因素，结果表明：Al2(SO4)3和Ca(OH)2用量分别为1 g/L和1.25 g/L，搅拌25 min，搅拌速率60 r/min，温度25℃，pH值7~8时，废水的絮凝处理效果最好。曝气生物滤池处理过程中，第7天时，固体菌S-1和液体菌L-1对废水的CODCr去除率最高，分别为74.6%和64.5％。经固体菌S-1处理后的废水COD-Cr为200 mg/L，达到了造纸厂废水回用的水平。
Abstract:
 The flocculation system of Al2(SO4)3 and Ca(OH)2 was combined with biological aerated filter (BAF) to treat bio-CMP pulping wastewater from wheat straw. The flocculation mechanism and the factors related with the flocculation effect were investigated. The results showed that the optimal flocculation effect was obtained when the dosages of Al2(SO4)3 and Ca(OH)2were 1 g/L and 1.25 g/L respectively, with 25 min stirring time at 25℃, stirring rate of 60 r/min, and pH 7~8. In the process of biological aerated filter treatment, the COD Cr removal rates of S-1 bacteria and L 1 bacteria to wastewater reached maxima on the 7th day, which were 74.6% and 64.5%, respectively. The COD Cr of the effluent treated by S1 bacteria was 200 mg/L, reaching the general reuse level for paper mill.
