| 摘 要： | 台州某电镀企业采用“软化+砂滤+超滤+反渗透”组合工艺深度处理高硬度电镀废水,实现了再生废水的回用。工程处理规模为150 t/d,出水水质为COD≤20 mg/L,电导率≤300μS/cm,SS≤10 mg/L,pH 6~9,回用率≥50%。该工程总投资100万元,直接运行成本为13.88元/t,软化处理和反渗透系统CIP在线清洗提高了工艺运行的稳定性,减少了反渗透膜的污堵。

| Abstract: | A combined process of"softening+sand filtration+ultrafiltration(UF)+reverse osmosis(RO)"is adopted to advancedly treat high hardness electroplating wastewater in an electroplating enterprise in Taizhou to reuse regenerated wastewater.In this project,the processing scale is 150 t/d.The effluent quality is COD≤20 mg/L,conductivity≤300μs/cm,SS≤10 mg/L,pH=6~9,and recycling rate≥50%.The total investment is 1 million yuan,and the direct operating cost is 13.88 yuan/t.Softening treatment and CIP online cleaning of RO system improve the operation stability and reduce the fouling of the RO membrane. |
