工艺特点 Technics Characteristic

      电镀废水中的主要污染物质均为各种金属离子，常见的有铬、铜、镍、铅、铝、金、银、镉、铁等，其实是酸类和碱类物质，如硫酸，盐酸，硝酸，磷酸和氢氧化钠，碳酸钠等到，有些电镀液还使用了颜料等到其它物质，这些物质大部分是有机物，另外，在镀件基材的预处理过程中漂洗下来的汕脂，油污，氧化铁皮，尘土也被带进了电镀废水中。
①同传统的处理工艺相比较，最新的电镀废水处理方案大大减少了酸碱溶液的使用量，不但降低了系统的成本投入，且利于环保。②该工艺的产水水质标准相对较高，能够达到工业软化水标准，因而回收的产水可以用于一些生产中的辅助用水。③采用了膜组件作为工艺的核心处理环节，整体工艺设计合理，具有非常高的可靠性能，使得系统的运行效率大大提高。④废水可以直接进入膜分离设备，无需添加药剂降低了系统的运行成本，且简化了操作步骤，便于管理。
      The main pollutants in electroplating wastewater are metal ions, such as chromium, copper, nickel, lead, aluminum, gold, silver,cadmium, iron and so on. They are acids and bases, such as sulfuric acid, hydrochloric acid and nitric acid. Phosphoric acid andsodium hydroxide, sodium carbonate wait, some electroplating solutions also use pigments to wait for other substances, thesesubstances are mostly organic matter, in addition, in the pretreatment process of the base material washed off Shantou grease,oil. lron oxide and dust are also brought into electroplating wastewater.
      Compared with the traditional treatment process, the latest electroplating wastewater treatment scheme has greatly reduced theuse of acid-base solution, not only reduced the cost of the system. The water quality standard of this process is relatively highand can reach the standard of industrial softened water. Therefore, the recycled water can be used in some auxiliary water inproduction.3. The membrane module is used as the core of the process. The overall process design is reasonable and has avery high reliability. The operation efficiency of the system is greatly improved. 4 wastewater can be directly entered into themembrane separation equipment. The operation cost of the system is reduced without adding medicament, and the operationsteps are simplfied. The convenient management of 5.
