Water reuse: is the industrial wastewater through the depth of treatment, to remove all impurities, water pollution of poisonous and harmful substances and some heavy metal ions removal, disinfection and sterilization, the water is colorless, tasteless, water is clear and transparent and reached recycling standards.
Process flow chart:
The raw water tank, the raw water booster pump, the activated carbon filter, the ultra filtration, the water tank, the booster pump, the security filter, the high pressure pump, the reverse osmosis system, the pure water tank, the water point
Water reuse system is to discharge standard industrial wastewater as the raw water, before the pretreatment, and then through the RO reverse osmosis treatment. After a series of pre-treatment, can go to the water in the particles, colloids, organic impurities, heavy metal ions, bacteria, viruses, heat and other substances and  dissolved salt.
The system includes the pretreatment part (booster pump, mechanical filter, activated carbon filter, ultrafiltration system, 5 m security filter); RO reverse osmosis.
The system as a whole, each process is linked to each other, the effect of the previous treatment process may affect the next level processing technology, the entire system may affect the terminal water production.
Water quality: the indicators can meet the requirements of the new standard table 3。
Usage: suitable for electroplating wastewater in the indicators seriously overweight or have a certain return to the requirements of the enterprise.
Water reuse equipment for electroplating industry
Industrial wastewater, water reuse is mainly used RO reverse osmosis system to deal with, to achieve the purpose of recycling. Main processes are:
1, pretreatment +UF+ single reverse osmosis
2, pretreatment +UF+NF+ single reverse osmosis
3, pretreatment +UF+ double reverse osmosis
4, pretreatment +UF+NF+ double reverse osmosis
The advantages of the reverse osmosis system: the water quality is good, which can meet the requirement of industrial production. System water stability. High water recovery rate.
According to the water quality, water quantity, water quality and quantity demand, the optimum treatment process was considered. At present, the treatment process of wastewater is mainly treated by two stage biochemical treatment and three advanced treatment units. Different water quality requirements, processing technology is also different. The biochemical method and the MBR membrane reactor process are two main treatment processes, which are based on the different nature of the sewage.
Technology of reclaimed water reuse equipment for electroplating industry
Electroplating industry with the water back to the equipment is using membrane separation technology to chemical, electroplating, paint and other industrial waste water according to different processes of separating and unvarnished concentrating and return to the liquid tank use, and through the water as the process of cleaning water using closed loop water.
Design principles of reclaimed water reuse equipment for electroplating industry
1, the use of advanced cycle of biological oxidation process, to ensure that the sewage treatment to achieve the premise, the investment will be reduced to a minimum.
2, designed to make full use of the advantages of structures and equipment, so that the sewage treatment and water reuse facilities layout is reasonable, as far as possible to reduce the area, and the sewage treatment station and the surrounding environment.
3, in view of the actual situation of the factory, and strive to operate conveniently.
4, in order to prevent the construction of sewage treatment facilities on the surrounding environment caused by the two pollution, design of the use of noise free underwater aeration machine instead of air blower, and from the process to achieve no sludge or less sludge discharge.
