Electroplating wastewater treatment equipment What are the advantages of
Sewage treatment equipment has attracted wide attention. The electroplating process control technology at home and abroad has developed rapidly. With the rapid development of the electroplating industry, the requirements for environmental protection have become increasingly high. At present, it has begun to enter the cleaner production process. Integration of total volume control and circular economy. In recent years, with the continuous progress of the environmental protection industry, electroplating wastewater treatment equipment has been developed rapidly under the guidance of the policy of rapid development. The wastewater treatment equipment manufacturing enterprises focusing on technological transformation have improved their production capacity and level, and the production level of supporting equipment for special equipment for wastewater treatment in the city has been greatly improved, with broad prospects for development.
What are the advantages of electroplating water treatment equipment?
Few systems: the surface biofilm is formed, which is basically digested and absorbed, and only a small amount of sludge is discharged from the decentralized sewage treatment unit. Low operation cost: simplify the sewage treatment process and greatly reduce the operation cost. After the reactor is put into operation, the effluent quality shall meet the national discharge standard, and the treatment of integrated sewage system and similar organic sewage shall be ensured. Good flow performance: modular structure is adopted, the treatment scale is determined according to the sewage treatment capacity, and the field installation adaptability is strong: it can be widely used in various places, and the operation mode is flexible: the main treatment unit adopts synchronous parallel operation, and flexible operation mode is selected.
Passivation solution after treatment. Galvanized. The nickel plating water is washed into the large regulating tank. After all kinds of wastewater are fully homogenized in the regulating tank, they rise from the lift pump to the reaction tank 1, enter CaCl2 through the metering pump, destroy Zn2+complexes, enter the reaction tank 2 through the metering pump, adjust the pH value to 9-11, and the sewage flows through the reaction tank 3, enter the coagulant aid PAM through the metering pump, and the electroplating wastewater treatment equipment enters the inclined plate sedimentation tank, The metal hydroxide sludge is settled into the sludge hopper, and the supernatant flows into the neutralization tank automatically for acid-base regulation, so that the pH is reduced to 6-9, and then discharged. The sludge from the inclined plate sedimentation tank is regularly discharged into the sludge tank, treated into sludge cake by the box filter press, discharged, and then sent back to the throttling tank.
There is no phase change in the process of ultrafiltration equipment treatment, and there is no adverse effect on material components. It is also separated and purified. During the concentration process, it is always kept at normal temperature, especially suitable for the treatment of heat sensitive substances, which completely solves the problem of destruction of bioactive substances caused by high temperature, and effectively protects the biological activity and nutrients in the raw material system. Its energy consumption is low and the production cycle is short. Compared with the traditional process equipment, the equipment operation cost is low, which can effectively reduce the production cost and improve the economic efficiency of the enterprise. The ultrafiltration system has advanced process design, high integration, compact structure, small floor area, simple operation and maintenance, and low labor intensity. The ultrafiltration equipment system is made of sanitary pipe valves, and the site is clean and sanitary, meeting GMP or FDA production requirements.
