对絮凝法处理环烷酸废水过程中有重要影响的因素进行了小试实验研究,得出了去除废水中CODCr的最佳絮凝条件:选用聚合硫酸铁(PFS)+阴离子聚丙烯酰胺(PHP)药剂,PFS投药质量浓度为275mg/L,PHP投药质量浓度为8mg/L;pH值对絮凝没有影响;温度对絮凝效果有影响,温度越低絮凝效果越好。以小试实验数据为依据,确定中试实验最佳投药量,PFS为275mg/L,PHP为6.7mg/L,在此条件下处理环烷酸废水,CODCr去除率达到83.1%。
The experimental study on the factors influencing the process of naphthenic acid wastewater treatment by flocculation indicated that the optimal flocculation conditions for the removal of CODCr in wastewater were as follows: PFS + anionic polyacrylamide (PHP) Pharmacy, PFS concentration of 275mg / L, PHP concentration of 8mg / L; pH value has no effect on flocculation; Temperature has an effect on the flocculation effect, the lower the temperature the better the flocculation effect. Based on the experimental data, the optimum dosage of Pilot experiment was determined. PFS was 275mg / L and PHP was 6.7mg / L. Under this condition, the removal rate of CODCr reached 83.1%.
