As a clean energy source, solar energy has been widely developed and applied. A solar cell is a device that uses sunlight to generate a photoelectric effect and convert light energy into electrical energy. China is an important producer and exporter of solar cells, and has assumed important responsibilities in the solar cell industry. As the solar industry continues to grow, solar cell production has also exposed some problems. In the case of increasing environmental protection needs, the wastewater treatment generated in the production of solar cells has become a work that needs to be carried out in depth.
MBR curtain membranes are used in the production of solar cells to provide technical support for wastewater treatment at the back end of the industry. Solar cell production wastewater contains polyethylene glycol, hydrofluoric acid, silica fume, detergent, surfactant and other components, which is an organic wastewater with large water volume, strong pollution and unstable water quality. Among the various polluting components, the degradation of polyethylene glycol is particularly difficult, and the treatment technology is very picky.
MBR cord membrane solves the wastewater of solar cell production with the following advantages:
1.Stable effluent quality: high filtration accuracy of membrane filament, good effect of intercepting pollutants, narrow pore size distribution, effective prevention of irreversible membrane blockage, high effluent efficiency
2.Strong fouling resistance: with special anti-fouling design, it can effectively prevent the accumulation of impurities, prevent the occurrence of compaction, and is easy to maintain and clean
3.High membrane flux: excellent membrane filament structure design, high porosity and uniform distribution, low filtration resistance, high permeate flux, low operating energy consumption;The membrane filament filling rate is very high, the filtration area is larger under the same volume, and the work efficiency is high
4.Good mechanical strength: the membrane filament has good flexibility and strong tensile resistance, which can effectively prevent the membrane from being damaged during operation and cleaning
5.Excellent material design: PVDF material is selected, which has stable chemical properties, can adapt to a variety of chemical cleaning methods, and prolongs the service life.
Relying on the above advantages, polyethylene glycol, hydrofluoric acid, silicon powder, detergent, surfactant and other components contained in solar cell production wastewater will be effectively removed, which greatly reduces the risk of environmental pollution and improves the comprehensive benefits of the solar energy industry.
