五十年来我国电镀废水治理的回顾文章编号:100123849(2000)0220006203α五十年来我国电镀废水治理的回顾黄瑞光(中国电子工程设计院,北京100036)摘要:近年来我国政府和电镀企事业单位都十分重视电镀废水治理工作,投入巨资治理废水取得巨大成效。但是还有极少数厂点至今排出废水仍不能达标,分析其原因,有的对废水治理的机理不甚了解,有的操作或投加药剂不准确,有的对目前化学法治理缺乏信心,也有的出于管理问题。综合目前存在的问题提出解决办法,以资提高治理水平。关键词:电镀;废水治理;达标;排放中图分类号:X78811文献标识码:ALookingBackontheElectroplatingWaste-waterTreatmentinthePast50YearsSincetheFoundingofNewChinaHUANGRui2guang(ChinaElectronicsEngineeringDesignInstitute,Beijing100036,China)Abstract:Itisfoundfromthelookingbackontheelectroplatingwaste2watertreatmentinthepast50yearssincethefoundingofNewChinathatourgovernmentandenterprisesintheelectroplatingindustryhavebeenpayingattentiontotheelectroplatingwaste2watertreatmentveryseriouslyandmadehugeinvestmentforthem.Greatsuccessfulresultshavebeenobtained.Buttoday,pollutantinwaste2waterdrainingfromafewfactoriesremainnottocomeuptothestandard.Causesofthisareunderstandingofthetheoryandmechanismofthetreatmentbeingnotclear,operatingandchemicalsaddingunaccuracy,orsometimeproblemsappearingfromthema
