Abstract

The invention discloses an efficient defluorination microbial flocculant applied to photovoltaic wastewater, and relates to the technical field of biological method wastewater treatment materials, the microbial flocculant comprises a fluorine-resistant bacterium suspension, nutritional ingredients and a solid-phase carrier; the fluorine-resistant bacterium suspension is a liquid fluorine-resistant flora, and comprises effective fluorine-resistant bacteria with the viable count of not less than 1 billion/g; the nutritional ingredients comprise cane sugar, urea, ascorbic acid and dipotassium phosphate; and the solid phase carrier comprises one or more than two of wheat bran, corn flour and soybean meal. The liquid fluorine-resistant microbial agent is prepared from liquid fluorine-resistant flora obtained from sludge polluted by fluorine-containing organic compounds, cane sugar, glycerol, urea, ascorbic acid, dipotassium phosphate and monopotassium phosphate. The microbial flocculant prepared from the raw materials has selectivity on fluorine ions, is high in efficiency and small in usage amount when being used for treating fluorine-containing industrial wastewater, is short in time of forming flocculation in water, is environment-friendly and does not generate secondary pollution.

Description

technical field [0001] The invention relates to the technical field of biological wastewater treatment materials, in particular to a high-efficiency defluoridation microbial flocculant applied to photovoltaic wastewater. Background technique [0002] Photovoltaic industry refers to the photovoltaic conversion industry chain that revolves around the photovoltaic effect of solar power generation and provides raw materials, batteries, components and systems and ancillary products required for industry development, including the production of high-purity polysilicon raw materials, solar cells and components, and related production. equipment manufacturing, etc. Compared with traditional energy sources such as hydropower, wind power, and nuclear power, solar power generation is cleaner, safer, and more reliable. The system can generate electricity independently and be connected to the grid, which has broad prospects. In recent years, accelerating the development of the photovolt...
