Abstract

The invention provides a membrane-method high-powered recycling process for fluoride-containing wastewater generated by the photovoltaic industry. The membrane-method high-powered recycling process is characterized by comprising the following steps of: firstly, pre-treating the collected fluoride-containing wastewater; then, introducing the pretreated fluoride-containing wastewater to a membrane separation treatment system, and carrying out further purification treatment on the fluoride-containing wastewater to obtain produced water and concentrated water; next, carrying out up-to-standard discharging treatment on the obtained concentrated water, and then, discharging the concentrated water; and finally, drying sludge, and then, outwards transporting the sludge, wherein the sludge is generated in the system purification treatment process. After the membrane-method high-powered recycling process for fluoride-containing wastewater generated by the photovoltaic industry, provided by the invention, is adopted, the produced water is recycled, so that a great deal of fresh water is saved, the high-powered recycling of the fluoride-containing wastewater is realized, the discharged pollutants and the emission are reduced, the resource is saved, and higher economic, social and environmental benefits are created for enterprises.

Description

technical field [0001] The invention belongs to the technical field of recovery and treatment of fluorine-containing wastewater in the photovoltaic industry, and specifically relates to a special high-power recovery system for the membrane method of fluorine-containing wastewater in the photovoltaic industry. Background technique [0002] The photovoltaic effect is used to make sunlight shine on silicon materials to generate electricity directly. The industrial chain formed by the application and development of silicon materials is called "photovoltaic industry", including the production of high-purity polycrystalline silicon raw materials, solar cell production, and solar cell module production. , Manufacturing of related production equipment, etc. The production of pure polysilicon raw materials will produce a large amount of fluorine-containing wastewater. The high oxidation of fluorine-containing wastewater will cause serious pollution to the environment, and direct disc...
