摘　　要：采用酸性混凝+高级氧化+生物接触曝气系统处理红板(江西)线路板厂有机显影废水,并通过正交实验确定最佳药剂投加量。结果表明,处理500mL显影废水的最佳工艺条件是pH为4.0,10%的PAC的投加量为3.3mL,0.2%的PAM投加量为3.4mL,10%的FeSO4·7H2O的投加量为2.7mL,30%的H2O2投加量为0.72mL,10%的Na2S投加量为4.4mL,10%的LIME投加量为7.7mL,0.2%PAM投加量为4.6mL。将最佳工艺条件应用于工程实践,处理后废水COD的值降为75mg/L,低于《污水综合排放标准》(GB8978-1996)一级排放标准中COD的最高允许排放浓度。The acidic coagulation ＋ high-level oxidation ＋ biology contact aeration system were used to treat developing wastewater from Red Board（Jiangxi） LTD..The optimum operating conditions were studied by orthogonal test,which were showed as follows：a pH value of 4.0,a dosage of 10% PAC of 3.3 mL,and a dosage of 0.2% PAM of 3.4 mL in the acid treatment system,while the dosages of 10% FeSO4·7H2O of 2.7 mL,10% Na2S of 4.4 mL,10% LIME of 7.7 mL,and 0.2% PAM of 4.6 mL in the high-level oxidation system.Under these conditions,the content of COD in effluent can be reduced to 75 mg/L,reaching the first level criteria specified in ＂Integrated Wastewater Discharge Standard＂.
