电镀行业现状及推行清洁生产的措施

Cleaner Production Measures and Status Quo of Electroplating Industry

20世纪80年代以来,我国电镀企业的数量迅速增长,然而规模普遍偏小,存在金属原料利用率低,单位面积镀层能耗、水耗水平高,污染物以末端治理为主,管理水平低等问题,要实现电镀行业的可持续发展,实施清洁生产势在必行。文章提出电镀行业的清洁生产可从采取采用清洁生产工艺、减少废水量、进行节能改造、加强企业管理等方面着手。其中,可采取改善清洗方式,减少带出液,加强废水回用的措施减少废水量;可采取使用高频开关电源,选用清洁能源加热技术,增加变频技术的措施降低电镀企业能耗。从而为电镀行业的节能、降耗、减污、增效提供有效途径,为电镀企业的可持续发展提供明确方法。

The quantity of electroplating enterprises was rapidly increasing in 80 age 21st Century in our country,but they were general relatively small,and had problems such as low utilization rate of metal material,high energy and water consumption level of unit area of cladding material,pollution end treatment pattern,low control level and so on.Cleaner Production（CP） was imperative for sustainable development of electroplating industry.It was proposed that CP of electroplating industries could develop from using CP technology,reducing waste water,having energy saving measures,reinforcing business administration these aspects in the paper.Among them,mending washing fashion,reducing liquid carried over,enhancing wastewater reuse could be used to reduce wastewater;Using HF switch power source,selecting clean energy for heating,adding converter technique could be used to reduce energy consumption of electroplating enterprises.Thus it could offer effective way to conserve energy,reduce materials,reduce pollution,and increase benefits for electroplating industries and provide explicit method for sustainable development of electroplating industries also.
