Industrial aluminum profile surface wastewater treatment technology
Industrial aluminum profiles will produce a lot of wastewater when conducting research surface treatment, and there are certain harmful material culture in the wastewater for discharge. If no analysis and treatment will be performed, it will affect students to a certain impact on social environmental factors. Then China's industrial aluminum profiles will be What are the wastewater processing data technologies for wastewater treatment? Below is we understand by specific understanding. Top ten brands of aluminum and products made by other alloy elements. It is usually made into a casting product, forging products, as well as foil, board, band, tube, stick, profile, etc., and then made by cold bending, sawing, drilling, assembly, coloring and other processes. The main metal elements are aluminum, which adds some alloy elements to improve the performance of aluminum. The two-sided aluminum plate of the whole aluminum home, and the PVC plate core filled in the middle of the PVC board is usually about 1.4-1.8 density values (the smaller the density value, the better the quality). The material of the doors and windows and doors and windows is connected to the wall. The main feature is that the surface of the wall is mostly plane, and it cannot be moved on the wall.
1. Surface information of aluminum profiles to deal with the source and type of wastewater of life -long wastewater
Wastewater treatment of aluminum surface pre -treatment is dehydrated and washed, sour water was washed after oxidation, the color Ni2, medium SN2, pickled water, and alkaline washing water in the alkaline washing water after the ion was exchanged. The amount of acidic swimming is small, and the amount of waste -alkali electrophoretic coatings of wastewater is small. Hybrid acid wastewater contains AL3, NI2, medium SN2, SN4, sodium ions, () and other cations and SO42-, F-, NO3-, chloride ion, ALO2-, other anion, surface active agent and Acrylic and organic resin. Waste liquids and wastes produce waste sulfuric acid, waste sulfuric acid, and nitric acid waste liquid produced by oxidized, shaded waste, waste liquid acrylic sedimentary coatings, which causes blocking nickel, F-and analog.
2. Reduce corporate wastewater and waste liquids for discharge
The methods to reduce wastewater and waste liquids are reasonable to control the time of water control and control the amount of moods to reduce the amount of groove liquid. Try to use a secondary and three -level countercurrent rinsing to reduce the amount of water consumption. Washing water after acid erosion and dehydration is used for water washing after alkaline corrosion. After oxidation, water washed water for acid erosion and dehydration. In addition, in order to reduce or avoid discharge of wastewater and waste groove liquids, the production line should be designed and used to use various recycling devices, such as acid erosion recycling device, alkaline erosion recycling device, anode oxide removal device, color solution RO recycling device, electrophoretic paint RO The recycling device can reduce the amount of wastewater and waste liquid discharge to a large limit, and at the same time, the production cost can be reduced.
3. Principles and methods of the surface treatment of aluminum profiles
The aluminum surface produced by wastewater is nickel, nickel, medium SN2, F-and other small harmful pinerals and cations are mainly acidic wastewater and acid-alkali treatment. Wastewater is usually acidic, and the alkali is added, and the pH value is adjusted to about 78.5. And, in the cationic al3, Ni2, medium SN2, CR3process, etc., forms hydroxide precipitation. After the precipitation of neutralized and wastewater flocculation ponds, the measurement pump was pumped into the well at the same time to solve the polyamide and wastewater flocculant, solidify the wastewater into the sedimentation tank, the sedimentation method of the diagonal disk is precipitated, flotal, centrifugal precipitation method, etc., I believe It is a more stable use of centrifugal settlement. Through the sedimentation, the upper part of the upper part of the outflow exit or overflow storage from the can.
After analyzing the above data processing, the wastewater can be discharged at the standard. If the production wastewater is used, the wastewater technology can enter the RO device system through the rough filtering to process the information processing to remove the excess yin and yang ions and organic matter. This The water pH value of the time may be low. It can be found that the reincarnation standard is reached after the structure of the exchange control device is adjusted by the exchange control device between the yin and yang ions. The sludge generated by the precipitated development is regularly discharged into the sludge pool, and it becomes China's industrial waste residue after treatment through the plate -type cake machine or with dehydration machine, and is delivered to the industrial waste residue treatment plant.
