Electroplating wastewater treatment method how to deal with electroplating wastewater zui is appropriate
In recent years, with the pursuit of quality of life, electroplating has long been an indispensable process in many industrial sectors, and China's electroplating industry is facing a major development opportunity.
However, although electroplating technology is already indispensable, it is one of the heavily polluting industrial industries in China because it uses a lot of toxic and harmful chemicals such as heavy metal solutions in the process. Therefore, electroplating wastewater must be handled with caution.
Introduction to electroplating wastewater treatment methods. First, the main production part of electroplating wastewater is composed of pretreatment acid-alkali washing wastewater and electroplating process rinsing wastewater. The pollutants required by the acid-base wastewater group are washed oil, rust, acid and alkali. After simple materialization treatment, it can be discharged or reused, but the materialized treatment cost is high, and the land occupation is large. Generally, it is not recommended. How to deal with electroplating wastewater?
According to new news from Zui, the membrane treatment process as a new process for the treatment of electroplating and rinsing water provides a “green†solution for electroplating and rinsing water treatment. The wastewater from the rinsing tank is transported by a water pump to a continuous membrane system for separation and concentration. The concentrate enters the evaporator and is further concentrated or configured with a new plating solution, and returned to the plating tank. A filter is used for pretreatment before film introduction to remove possible particles to ensure the safety of the membrane system. The permeate of the membrane separation system fully meets the deionized water standard and is returned to the third rinse tank for reuse. Therefore, a closed loop processing system is realized. In the whole circulation system, no other substances enter, and there is no material loss, and the material balance is reached. After treatment, the nickel ion is less than 0.2 mg/l, and the water reuse rate can reach 95. %the above.
At present, Shanghai Yishuang Water Treatment Equipment Co., Ltd. http:// is a well-established company in this area. The company is a fully-automatic electroplating wastewater treatment technology, water treatment equipment manufacturing, installation and service. As one of the water treatment companies, well-equipped, service in place, professional staff, is the preferred electroplating wastewater treatment company in China.
The implementation of new pollutant discharge standards in the electroplating industry in these years has greatly improved the control requirements for pollutant emissions in the electroplating industry. Therefore, enterprises need to adopt more advanced technologies, cleaner production technologies and more effective pollution control measures to adapt to the new form. China's electroplating industry policy development policy.
