Electrophoretic coating is a special coating method developed in recent 30 years. It has the characteristics of water solubility, non-toxicity and easy automatic control. It is widely used in automobile, electronics, building materials, hardware and other industries. Therefore, electrophoresis wastewater is produced and becomes a kind of industrial electrophoresis wastewater which appears widely. The wastewater has the characteristics of many kinds of pollutants and complex components. In addition, due to the large differences in the scale of various industries and enterprises, the water quantity and quality of electrophoresis wastewater are also large, and the treatment process of electrophoresis wastewater is inevitably diversified.
1. Electrophoresis production line process overview:
In the early stage of electrodeposition treatment, all kinds of dirt (oil, rust, oxide scale, welding slag, metal chips, etc.) attached to the surface of the coated object should be cleaned first. All kinds of cleaning systems should include at least three steps: pre-degreasing, degreasing and washing.
1. Pre-degreasing: It is to manually wipe or spray degreasing agent on the surface of the workpiece, prepare for the next degreasing station, and keep the surface of the workpiece wet to prevent the loose dirt from drying again, because if the removal is not clean, it will lead to the appearance of the phosphor layer.
Degreasing: Usually degreasing is carried out by immersion or spraying after pre-degreasing. The working solution is an alkaline solution containing a variety of surfactants, and its concentration, temperature, treatment time and spray pressure are recommended by the supplier. Working fluid can be recycled, but should be equipped with oil-water separation system to ensure that the oil content in the degreasing fluid is below the specified value.
At present, there are physical membrane (CUF) separation method and heating U-tube mechanical pen oil device commonly used for oil-water separation. In front of the oil-water separator must be equipped with triple bag filtration, strong magnetic filtration, microporous membrane filtration system.
Phosphating: dip or spray method, the working solution is zinc, manganese, nickel compound phosphating solution, its concentration, temperature, treatment time and spray pressure recommended by the supplier. Working fluid can be recycled, should be equipped with high-level slag tank and continuous filter press to keep the tank liquid clean.
4, washing: pickling, degreasing, phosphating, into the washing, mainly to clean off the workpiece surface residual degreasing, phosphating agent and attachments. Washing can be carried out by spraying or immersion, using circulating clean water cleaning, continuous production, should maintain a certain amount of overflow to control the pH value of clean water and alkaline cleaning agent concentration, so that the workpiece surface is completely cleaned. The three kinds of washing solutions were weak acid and weak base respectively.
II. Main Pollutants in Electrophoresis Wastewater
Electrophoresis wastewater mainly contains PH, CODcr, ammonia nitrogen, total phosphorus, petroleum, total zinc and so on
3. Electrophoresis wastewater treatment process:
IV. Electrophoresis wastewater treatment discharge standards:
The— allowable discharge concentration of water pollutants discharged into the sewage treatment plant after the discharge standard of electrophoresis wastewater treatment equipment complies with the Class I discharge standard in Comprehensive Sewage Discharge Standard (GB 8978 1996). Specific emission standards are shown in Table 1.

Shanghai Yishuang Environmental Technology Engineering Co., Ltd. was established in 2008. The company is located at No. 85 Mingnan Road, Songjiang District, Shanghai City. It has been committed to technical research and development of pollution control projects for many years, mainly engaged in industrial wastewater and waste gas treatment (Wastewater treatment in electrophoresis, coating, spraying, electroplating, acid cleaning and phosphating, surface treatment, electronics, circuit board, semiconductor, metal products, machining, electrical, steel, silane, auto parts and other industries) Medical wastewater, breeding wastewater, The treatment of washing wastewater, mainly undertakes various environmental pollution prevention and control projects general contracting projects, entrusted operation projects, industrial wastewater treatment projects, high-purity water projects, waste gas treatment projects, and industrial emission reduction third-party environmental management projects. The company now has a group of elite teams, multiple registered builders and senior engineers, and has established a complete pre-sales and after-sales service system, integrating engineering consulting, testing and analysis, scheme design, equipment manufacturing, installation and debugging, personnel training, technical services, project acceptance, after-sales one-stop service. After years of continuous technological innovation, it has obtained many patents. With efficient environmental protection equipment, high-quality environmental protection projects, Continuously obtain the "Level 1 Qualification Certificate for General Contracting of Environmental Pollution Control Projects","Special Engineering Design Certificate","Member Certificate of China Environmental Protection Industry Association","Member Certificate of Shanghai Environmental Protection Industry Association","Top Ten Brand Enterprises in China's Water Treatment Equipment Industry in 2012""Top Ten Environmental Protection Enterprises in 2010","Chinese Painting Industry Enterprises Commemorating the 40th Anniversary of Reform and Opening up","Emphasizing Contracts, Honorary titles such as "Promising Environmental Protection Enterprise" and "Governing Unit of the Coating Industry Development Promotion Center of the China Equipment Management Association" have won the trust and praise of the industry and customers. Now completed projects have spread across the country and are exported to Vietnam, Russia, Portugal, South Korea and other countries. Since the "Thirteenth Five-Year Plan" period, my country's environmental protection system has been greatly improved, and laws, regulations, policies, standards, etc. have become increasingly complete. With the continuous development of national environmental protection policies and the new situation of environmental pollution control changing to environmental quality, Environmental protection actions are increasingly targeted at specific sub-areas. Special governance will be a trend to solve environmental problems. The market requires higher and higher environmental protection technology and equipment, and the requirements for pollution control projects for enterprise technology and processes have been significantly increased. The pollution control products and environmental services provided by the environmental protection industry not only create economic value for customers, but also generate greater social and environmental benefits. Under the new requirements of economic development, Yishuang will continue to improve the innovation and manufacturing of environmental protection equipment, increase the efforts to overcome key core process technologies and transform results, strengthen the docking cooperation between environmental protection equipment manufacturing and global manufacturing, and continue to provide practical services to customers. Viable special solutions for pollution control truly achieve clean production, energy conservation, consumption reduction and pollution reduction, and recycling and reuse water resources.- Name（chinese）
