摘要
电镀废水含有大量铜、镍、铬等有价金属离子,直接排放对环境污染严重。文章介绍了某电镀厂采用离子交换—反渗透法对含镍废水进行在线回收,取得良好的效果。不仅符合国家的最新的电镀污染物排放标准,还可以回用到生产中,取得较好的经济效益和环境效益。
Electroplating wastewater contains large amounts of copper, nickel, chromium and other valuable metal ions; the direct discharge to the environment pollution is serious. The paper introduces an electroplating plant by ion exchange of online recovery of nickel containing waste water reverse osmosis, and achieved good results. Not only meet the country's latest electroplating pollutant discharge standards, can also return to production, and achieved good economic benefit and environmental benefit.
