Gongye shui chuli, 2018 采用TFS-OF+RO工艺分类处理含铬和含镍废水，工程运行情况表明：TFS-OF+RO工艺对污染物的去除效果好。镍、铬、锌等重金属污染物的去除率均>97%，其他污染物的去除率均超过92%。处理后的生产废水70%可以回用作电镀等生产用水，其余执行《电镀污染物排放标准》（GB 21900-2008）表3的特别排放限值要求达标排放。

Gongye shui chuli, 2013 为使铝型材生产产生的含铬废水的处理出水达到Cr6+≤0.5 mg/L要求,分别选用Na2SO3和Na2S2O5进行还原沉淀处理,并对影响处理效果的因素进行了分析比较。结果表明,还原处理铝型材生产产生的含铬废水时,Na2S2O5的投加量可比Na2SO3减少25.0%～37.5%;处理过程中,应控制混凝沉淀pH为8.2～9.0、PAM投加量为0.010g/L、沉淀时间为1~2 h。

Gongye shui chuli, 2008 介绍了电解法处理混合电镀废水的工艺。试验表明,对于含铬、镍、铜分别为<；100、<；40、<；60 mg/L的混合电镀废水,经过电解单元处理后,中水出水可达到铬、镍、铜分别为<；0.1、0.2、<；0.2 mg/L。该工艺所具有的独特优势是出水的回用可行性较高,在水资源日趋紧张的今天,具有很高的应用价值。
