Widespread attention is paid to sewage treatment equipment. Many electroplating development control technologies at home and abroad. With the rapid development of electroplating industry, more and more environmental requirements are required. At present, electroplating wastewater has begun to enter the integration stage of cleaner production process, total amount control and circular economy.
In recent years, with the continuous improvement of environmental protection industry, Electroplating wastewater treatment equipment To a certain extent, it has achieved rapid development, mainly under the guidance of the policy of rapid development, the technical transformation of major sewage treatment equipment manufacturing enterprises has improved their manufacturing capacity and level, and the production level of supporting equipment for special urban sewage treatment equipment has been greatly improved, which has broad prospects for development in the future.
What are the advantages of electroplating wastewater treatment equipment?
1. Less systems: the formation of surface biofilm has been basically digested, and only a small amount of sludge is discharged from decentralized sewage treatment equipment
2. Low operation cost: simplify the sewage treatment process and greatly reduce the operation cost.
3. High efficiency: after the reactor, ensure that the effluent quality meets the national discharge standards, and treat the integrated sewage system and its similar organic sewage.
4. Good liquidity: modular structure is adopted, and the treatment scale is determined according to the sewage treatment capacity. The field installation adaptability is strong: it can be widely used in various places,
5. Flexible operation mode: the key unit of machining is synchronous parallel operation, and flexible operation mode can be selected.

The passivation solution and pre-treatment after reduction treatment, the washing water for zinc plating and nickel plating enters the large regulating pool. After being fully homogenized in the regulating pool, various waste water is lifted to the reaction pool 1 by the lift pump, and then enters CaCl2 through the metering pump to destroy the complex of Zn2+. In the reaction pool 2, it enters NaOH through the metering pump, and the pH value is adjusted within the range of 9-11. Then the waste water flows into the reaction pool 3, The electroplating wastewater treatment equipment enters the inclined plate sedimentation tank after entering the coagulant aid PAM through the metering pump. The metal hydroxide forms sludge and sinks into the sludge hopper. The supernatant flows automatically into the neutralization tank for acid-base regulation. The pH value is adjusted within the range of 6-9 and then discharged. The sludge in the inclined plate sedimentation tank is regularly discharged to the sludge tank, treated into sludge cake by the box filter press, and then transported out for deep burial, and the sludge water returns to the regulating tank
The ultrafiltration equipment has no phase change in the process of processing, and has no adverse effect on the composition of the materials. It is always at room temperature during the process of separation, purification, and concentration. It is especially suitable for the treatment of heat sensitive substances, completely avoiding the disadvantage of high temperature destroying the bioactive substances, and effectively retaining the bioactive substances and nutrients in the raw material system. The ultrafiltration equipment system has low energy consumption and short production cycle. Compared with the traditional process equipment, the equipment operation cost is low, which can effectively reduce the production cost and improve the economic benefits of the enterprise. The ultrafiltration equipment system has advanced process design, high degree of integration, compact structure, small floor area, simple operation and maintenance, and low labor intensity of workers. The ultrafiltration equipment system is made of sanitary pipe valves, and the site is clean and sanitary, meeting the requirements of GMP or FDA production specifications.
