Circuit board factory in the process of production, the main pollutants to acid, alkali, Cu, SS and COD, etc. For emissions to clean waste water recycling, water saving, and obtain certain economic benefits, achieve win-win "development" and "environmental protection", the purpose of the printed circuit board waste water containing heavy metal ions such as copper, nickel, lead, tin, macromolecule organic matter, complexing agent and other pollutants, the heavy metal ions, PH, COD, SS are overweight .A wide range of PCB sewage pollution composition complex, if not take reasonable effective processing, make the waste stabilization, will cause serious pollution to the environment. The company according to the characteristics of the circuit board wastewater, after a lot of research, experiment analysis and engineering practice to develop the leading domestic wastewater treatment process. The process waste water main idea is to be classified collection, respectively take different treatment met hods.
Treated water of the system is stable and discharging standard, basic meet the requirements of the water. System process flow, layout reasonable, beautiful appearance, the application of automatic control, convenient operation, reliable operation. Pool body adopts unique one-piece structure, cover an area of an area small, save cost.
PCB process longer, system control node is numerous, all kinds of different nature of the waste water, waste water respectively, give priority to with heavy metal ions and COD pollution, waste water species complex, pH changes. Circuit board factory waste water can be divided into: general, printing ink wastewater and wastewater containing copper complexing copper wastewater, electroplating wastewater, water cleaning tank / plating tank inverted.
Production workshop each wastewater separately introduced to make pool, the reduction or processing such as oil-water separation, precipitation after micro filter, ultra filter, filter, filter and so on pretreatment, again after the secondary reverse osmosis system, the effluent water quality can reach the conductivity is less than 20 mu s / cm2, can recycle to workshop production water; After settling basin sludge dewatering entrusted to have an aptitude for dealing with environmental protection company processing; High COD waste water and the level of reverse osmosis system of concentrated water discharging standard by the wastewater treatment system.
Integrated soda acid wastewater and complex wastewater recycling by the advanced recycling system. Back to the water quality is better municipal water, can direct reuse to production line for general cleaning water, or for pure water manufacturing DI water system.
Triple membrane technology (that is, the superfine filtering and high scale system and purification system), effective control of reverse osmosis membrane congestion.
Reduce the reverse osmosis membrane cleaning frequency, prolong the service life of membrane, and reduce the cost of water recycling.
Strict QingZhuo diversion is a key to the success of the system, the key components in the system, by the high quality of imported equipment, research and development and design of unique system, to ensure that the system can long-term and stable operation.
The system advantages:
1.The water quality.
2.High degree of automation, stable water quality.
3.The energy-saving special process, operation cost is much lower than discharge and take on water, enterprise investment recovery fast.
4.A one-time investment is moderate, cover an area of an area small.
Heavy metal wastewater collection-------precipitation reaction--------the callback mixture of emissions
Metal complexing wastewater-------collection------precipitation reaction--------the callback mixture of emissions
Organic cleaning water collection----------(A / O) n biochemical treatment--------the callback mixture of emissions
Organic thick liquid waste collection----------pretreatment biochemical treatment
The above process can guarantee the stability of treated effluent discharging standard, basic meet the requirements of the water. System process flow, layout reasonable, beautiful appearance, the application of automatic control, convenient operation, reliable operation. Pool body adopts unique one-piece structure, cover an area of an area small, save cost.
