电镀废水处理设备发展方向
Development direction of electroplating wastewater treatment equipment
我国和其他国家一样，十分重视电镀废水的治理问题。在过去几十里，对电镀废水的治理方法进行了许多研究工作，在治理投资上也在不断增加，今后还会与过去一样，积极努力地解决这一问题。根据国内外对电镀废水的治理及研究情况，发展动向应为以下几个方面:
Like other countries, China attaches great importance to the treatment of electroplating wastewater. In the past dozens of years, a lot of research work on the treatment method of electroplating wastewater has been carried out, and the investment in governance is also increasing. In the future, it will work hard to solve the problem as in the past. According to the treatment and research situation of electroplating wastewater at home and abroad, the development trend should be as follows:
积极开展综合防治
Actively carrying out comprehensive prevention and control
经过几十年的发展，电镀废水的治理已经从原来的单纯“治废”，转变成综合治理，即进行既要防治，又要回收资源的积极方法。过去对清洗工艺进行了多方面的改革，成效显著。如多级逆流漂洗、水槽设计的改革、镀件吊挂方式的变化等，这些改革大幅度减少了镀液的带出，既回收了有用物质，又减少了电镀废水治理负担和治理成本，综合治理是防治污染的发展趋势，同时也存在许多技术问题尚待解决。
After decades of development, the treatment of electroplating wastewater has changed from the original "treatment and waste" to comprehensive treatment, that is, the active method to prevent and recover resources should be carried out. In the past, a variety of reforms have been made in cleaning technology, with notable results. These reforms, such as multistage backflow rinsing, the reform of the tank design and the change of the hanging style of the plating parts, have greatly reduced the discharge of the plating bath, not only recycling the useful material, but also reducing the treatment burden and the treatment cost of the electroplating wastewater. The comprehensive treatment is the development trend of the prevention and control of the pollution. At the same time, many technical problems still remain to be solved. No.
发展闭路循环
Development of closed circuit cycle
闭路循环是目前处理电镀废水最经济、最有效的方法之一，是治理电镀废水的方向，从而实现电镀漂洗水基本零排放。但到目前为止，末槽浓度的控制以及离子交换装置的应用与操作等问题还未得到很好的解决。
Closed circuit cycle is one of the most economical and effective methods to deal with electroplating wastewater. It is the direction of treatment of electroplating wastewater, and the basic zero discharge of electroplating rinse water is realized. But so far, the control of terminal concentration and the application and operation of ion-exchange devices have not been well solved.
改革电镀工艺
Reform electroplating process
改革电镀工艺是防治污染的根本方法，推广应用各种无氰、无铬以及其他无污染、少污染的电镀工艺，可以减少废水的污染源。无氰电镀、低铬钝化和以锌或锡锌合金代替镉等电镀工艺，还有用电泳漆代替电镀的场合也在增加。目前在国内许多单位都在进行探索和实践，但电镀还是不能被彻底替代的，而且还有许多具体问题需要解决。
The reform of electroplating technology is the basic method to prevent pollution. The application of various cyanide free, chromium free and other pollution free and less polluted electroplating processes can reduce the pollution source of the wastewater. No cyanide plating, low chromium passivation and zinc or tin zinc alloy instead of cadmium plating process, and electrophoretic paint instead of plating is also increasing. At present, many domestic companies are exploring and practicing, but plating cannot be completely replaced, and there are still many specific problems to be solved.
