摘　　要：电镀废水水质的日益复杂和地方排放标准的不断提高,使得电镀废水处理过程中面临更多挑战。对山东某电镀废水处理厂提标改造前后工艺及水质研究发现,原微电解/生物法组合工艺对重金属去除效果良好,生化出水中Cr^(6+)和Ni^(2+)含量分别低至0.01 mg/L和0.11 mg/L,出水Fe和Mn分别达到0.28 mg/L和0.08 mg/L,但COD及TDS不满足回用标准。为此,在深度处理工艺中采用陶瓷膜联合反渗透技术,使出水COD和TDS分别降至8.5 mg/L和136 mg/L,符合《城市污水回用设计规范》(CECS 61:94)中冷却水回用标准。此外,采用蒸汽再压缩技术(MVR)对反渗透浓水进行处理,实现了电镀废水处理的零排放。With the increasing complexity of electroplating wastewater quality and the improvement of local discharge standards, the electroplating wastewater treatment is facing more challenges than be- fore. The quality of the original and effluent of the improved treatment process for the eleetroplating wastewater in a electroplating wastewater treatment plant in Shandong Province was investigated. It was found that the original micro-electrolysis/biological combination process had efficient removal of heavy metals, the concentrations of Cr6＋ and Ni2~ in biochemical effluent were 0.01 mg/L and 0.11 mg/L, and the concentrations of Fe and Mn were respectively 0.28 mg/L and 0.08 mg/L. While, the removal efficiency of COD and TDS did not meet the requirement of reuse standard. Subsequently, ceramic mem- branes combining with reverse osmosis advanced treatment process was used to enhance the removal of COD and TDS. As a result, the effluent concentration decreased to 8.5 mg/L and 136 mg/L, respective- ly, which could meet the standard for reuse of cooling water in Design Standard for Municipal Wastewater Reuse （CECS 61：94）. In addition, the concentrated water generated from the reverse osmosis section was evaporated using mechanical vapor recompression, obtaining zero discharge of the electroplating wastewater.
