采用微电解-中和沉淀法处理含Cr6＋与Cu2＋电镀废水,探明pH与初始浓度对处理效果的影响。结果表明：用微电解法与碱液中和沉淀处理含Cr6＋与Cu2＋电镀废水去除率高,在质量浓度低于100 mg/L的情况下,处理后废水的Cr6＋与Cu2＋均可达GB8978-96《污水综合排放标准》中的一级排放标准,具有较好的工业应用前景。
採用微電解-中和沉澱法處理含Cr6＋與Cu2＋電鍍廢水,探明pH與初始濃度對處理效果的影響。結果錶明：用微電解法與堿液中和沉澱處理含Cr6＋與Cu2＋電鍍廢水去除率高,在質量濃度低于100 mg/L的情況下,處理後廢水的Cr6＋與Cu2＋均可達GB8978-96《汙水綜閤排放標準》中的一級排放標準,具有較好的工業應用前景。
채용미전해-중화침정법처리함Cr6＋여Cu2＋전도폐수,탐명pH여초시농도대처리효과적영향。결과표명：용미전해법여감액중화침정처리함Cr6＋여Cu2＋전도폐수거제솔고,재질량농도저우100 mg/L적정황하,처리후폐수적Cr6＋여Cu2＋균가체GB8978-96《오수종합배방표준》중적일급배방표준,구유교호적공업응용전경。
Micro-electrolysis-neutralization was utilized to treat the plating wastewater containing with Cr6＋ and Cu2＋.Discussed the influence of pH value and entry concentration.The results showed that the process had high removal efficiencies of those heavy metal ions.In the case of the entry concentration was below 100 mg/L,all the water quality indexes could satisfy the requirement of primary standard of the GB8978-96 after being treated.It had good prospect of application to industry.
