摘　　要：拟将高效沉淀池用于某炼化污水清净废水单元双膜前进行预处理,以降低水中悬浮物、硬度、二氧化硅等污染物,减轻污染物对后续双膜的污堵。通过实验对用于除硅的镁盐药剂进行比选,确定高效沉淀池所用药剂的投加顺序和最佳投加量,模拟验证工艺流程的合理性。Proposed high-efficiency sedimentation tank on a refining and chemical wastewater before the UF&RO membrane pre-treatment,reduce suspended solids,hardness,silica and other pollutants in the water,as well as pollutants on the subsequent membrane fouling.The magnesium salt agent for silica removal are chose by comparison;the optimal dosage of agents and the order of agents dosage are determined in high-efficiency sedimentation tank for simulation to verify the rationality of the process.
