摘　　要：为解决光伏太阳能电池生产时高F-含量废水达标排放难问题,研究采用2级化学混凝沉淀法进行了实验,通过单因素、正交实验考察了pH和CaCl2、PAC、PAM优选投加量。结果表明,当一级化学混凝pH为10,CaCl2投加量为3.0 g/L、PAC和PAM投加量分别为600、4 mg/L,一二级投药质量比为5:1时,最终出水达到GB 8978-1996一级排放标准限值。In order to meet the discharge standard of high-concenWation photovoltaic solar wastewater, the two-stage chemical coagulation and sedimentation was applied in test. The single, orthogonal factors were used to determine pH, CaCl2, PAC, PAM optimum dosages. The results show that the final effluent meet the GB 8978- 1996 standard limit when pH was 10, CaCl2 dosage was 3.0 g/L, PAC dosage was 600 mg/L, PAM dosage was 4 mg/L, dosing mass ratio of one and two-stage was 5：1.
