Glass wastewater treatment technology: Process: 1. Preparation of water glass deep-processing glass processing wash water requirements Water is pure water conductivity of less than 8μs / cm of. Raw water use municipal tap water systems by double filtration technology (multi-media filtration and activated carbon filtration) after pretreatment into reverse osmosis, the water can be directly used for washing, it can also be increased by the posterior segment of ion exchange resin treatment process to meet higher water requirements. 2, coated glass processing ultra-pure water preparation process coating line quality is poor conductor of claim, namely a resistivity greater than 16 MΩ? Cm of water. Usually UF (UF) devices, two RO (reverse osmosis) equipment, EDI (electrodeionization) means mixed bed polishing and other processes to obtain water, end the use of nitrogen sealed water tank shield in contact with the outside air. 3, washing Bender wastewater treatment and reuse online reverse bending process washing machine rinse water is usually pure water, high ground water costs, using online recovery process can be recycled water, reduce production costs. Through on-site reconstruction of the bending of the washing machine, the recovery process is mainly physical filtration process, taking into account the line operating conditions, using automatic control to achieve constant pressure water supply, and a temperature compensation device. 4, glass processing complex waste water treatment and reuse of glass processing complex waste water mainly comes from milling and washing steps, the main pollutants of glass powder and cleaning agents. Using one machine back water glass wastewater treatment by precipitation, flotation, filtration and other processes can achieve level reuse, instead of tap water for milling and washing stages, more than 95% recycling rate, operating costs of less than 0.5 yuan / ton water. 5, glass edging coolant treatment and reuse of glass processing production process, grinding process produces heat causes the ambient temperature increases, there will be a glass burns, reducing wheel life, edging phenomenon too long, can be added to the grinding wheel coolant prevention and mitigation of the above, and to improve milling efficiency, but more expensive one-time use. For milling Coolant centralized wastewater treatment, filtration device for processing by the vertical flow sedimentation and after HIP reuse system can recover 98% of the coolant, improve milling efficiency by 30%, while reducing costs. 6, coating refrigerated cooling water system process coated glass production line in the production process will generate a lot of heat, cooling needs in a timely manner in order to ensure that the device is working properly. Cooling water Process points refrigeration and cooling systems. Refrigerated cooling water system has three independent circulation cooling cathode respectively, cooling baffle plate, cooling the cathode power supply and power cabinet. Circulating cooling water (pure water) through the pump, radiator exchange, cooling water for cooling after coating line use outside circulating cooling water (tap water) provided in the workshop outside through the cooling tower for cooling. Process design, all pumps are used for constant pressure frequency energy control technology, stable and reliable system operation.
