传统处理工艺组合技术在治理电镀废水中的应用分析
|
摘要
我国水资源严重匮乏,人均水资源仅仅是世界人均水量的四分之一。现代工业给水资源带来了更大的压力,废水排放量也在不断增加。为了实现可持续发展,我国在治理废水上的投入也越来越大。电镀废水是全球三大工业污染之一,在其生产过程中会产生含有铬、镍、铜、镉、锌等重金属和氰化物、酸碱、光亮剂、添加剂等有害物质的污染源,由此可见,电镀废水的处理与回用对降低环境污染,提高水资源的利用率有着极其重要的意义。
Water resources in China are seriously deficient, and per capita water resources are only 1/4 of the world's per capita water volume.Modern industry has brought greater pressure to water resources, and the discharge of wastewater is also increasing. In order to achieve the sustainable development, China's investment in the treatment of wastewater is also increasing. Electroplating wastewater is one of the three major industrial pollution in the world. In its production process, it will produce heavy metals, such as chromium, nickel, copper, cadmium, zinc and other harmful substances, such as cyanide, acid and base, brighteners and additives. Therefore, the treatment and reuse of electroplating wastewater is of great significance to reduce environmental pollution and improve the utilization of water resources.
