| 摘 要： | 电镀园区废水处理过程中，由于园区企业难以做到彻底的分质分流，导致废水处理出现破络不彻底，次亚磷酸盐、氰化物等出现再络合与难降解等问题，同时，深度处理后，浓水需要进行深度处理，重金属离子浓度、总磷、总氮处理都存在难以达标的情况。本文根据企业电镀废水的典型水质和水量特征，研究设计了改进的CAFE处理工艺，详细论证了各工艺的处理过程、主要设备及相关设计参数，并将该工艺在南通某电镀园区电镀废水处理中进行了实际应用。运行的实践表明，该套设计方案污水处理运行稳定，最终出水的CODCr（化学需氧量）、NH4-N、总铬、六价铬、总镍指标的平均质量浓度分别为34.00、5.41、0.29、0.03、0.05 mg/L，均远远小于电镀废水的排放标准，达到了电镀废水的深度处理要求。

| Abstract: | In the process of wastewater treatment in an electroplating park, due to the difficulty of the enterprises in the park to completely separate the quality, the complex breaking of the wastewater treatment is not complete, the hypophosphite and cyanide are complex and difficult to degrade. At the same time,the concentrate has to be treated by advanced treatment, as after the treatment, the contents of metals, total phosphate and nitrogen are still not meet the drainage industial standard. According to the typical water quality and water quantity characteristics of electroplating wastewater in enterprises,the authors studied and designed the advanced treatment technology of innovated CAFE(catalysis-adsorption-filtration-exchange),and introduced in detail the treatment technology, the process,the main equipment and the related design parameters of each process,and further carried out the actual treatment of electroplating wastewater in an electroplating industrial park in Nantong. The practical application shows that the waste water treatment operation of the design scheme is stable. The average concentrations of CODCr,NH4-N,total chromium,hexavalent chromium, and total nickel in the final effluent are 34.00,5.41,0.29,0.03, and 0.05 mg/L,respectively,which are far less than the discharge standards of electroplating wastewater and meet the requirements of advanced treatment of electroplating wastewater. Based on cost-benefit analysis,the treatment has a good market prospect. |
