Introduction to the Surface Treatment Technology of Aluminum Profiles-WJW Aluminum Supplier Aluminum

The amount of water for aluminum profile is large, and the amount of wastewater is produced, and harmful substances in wastewater are continuously discharged. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration. If it is not handled, it will be contaminated with the environment. At the same time, with my country's taxation of sewage volume, it will also increase the capital of the enterprise and cumbersome. Therefore, from the aspects of corporate social obligations and benefits, the treatment of wastewater must be necessary.

1. The source and variety of wastewater in the nominal process of aluminum profile:

Answer: The wastewater processed in the nominal process of aluminum profiles contains the analogy water washing water in the previous treatment of acidic water washing water, alkaline water washing water after alkaline rotten water, acid water washing water after acid erosion, and an acidic water washing water after oxidized. SN2, acid water washing water, and electrophoretic paint ion exchange device produced by waste acids, waste alkali, and a small amount of electro -swimming paint water. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration. After the wastewater is confused, it is acidic, contains cations such as AL3, Ni2, SN2, SN4, NA, CR3and other cations, as well as the pangic ions such as SO42-, F-, NO3-, CL-, ALO2-, AC- Organic substances such as resin. Waste liquids have waste sulfuric acid produced in ablicse, waste nitric acid, and waste sulfuric acid produced by oxidized, waste liquid generated by coloring, waste acrylic liquid produced by electrophoretic paint, and waste liquids containing Ni2and F-produced by sealing holes.

2. Reducive method of reducing wastewater and waste liquid emissions:

Answer: The method of reducing wastewater and waste liquid is fair to reduce the amount of groove liquid with the angle of the controlling water, and try to use a secondary and three -level countercurrent rinsing to reduce the amount of water consumption. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration. Washed water after acid erosion and dehydration is used for washing after alkaline corruption. After oxidation, washing water was used for acid erosion and washing after dehydration. In addition, in order to reduce or avoid discharge of wastewater and waste groove liquids, the production line should be designed and using 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 may use these recycling devices to reduce the amount of wastewater with the discharge of waste liquids to a large limit, and at the same time, the production cost has also been reduced to a large limit.

3. Principles and methods for processing wastewater treatment in the nominal process of aluminum profiles:

Answer: The wastewater generated by the nominal processing of aluminum profiles is important acid-base wastewater, which contains a small amount of harmful yin and yang ions such as NI2, SN2, F-F-. The wastewater is some acidic, and the alkali heel is added, and the pH value is adjusted to about 7-8.5. At the same time, cations Al3, Ni2, SN2, CR3, etc. in the middle of the follow -up process have formed a hydroxide accumulation. After the pump that follows and accumulates the accumulated wastewater pump into the condensate slot, at the same time, use a quantitative pump to enter the dissolved polyamide condenser and the wastewater condensed. The law, centrifugal accumulation method, etc. The author believes that the use of centrifugal accumulation method is relatively firm. After accumulation, the clearing fluid overflows from the upper stream to the discharge pool or treats the reservoir. After the above -mentioned wastewater, it may be discharged by standards. If the wastewater is used for use, the wastewater at this time may be processed by rough filtering into the RO device to remove excess yin and yang ions and organic matter. At this time It may be reached after the yin and yang ion exchange device is adjusted. The accumulated sludge is discharged into the sludge pool on schedule, and it becomes industrial waste residue after processing through the plate cake machine or a dehydration machine, and sent it to the industrial waste residue treatment plant.
