Fluorine is an element widely distributed in the geosphere, and there are more than 80 fluorine-containing minerals known in the crust, such as fluorite, cryolite, various fluoride salts, fluorapatite and so on. In industry, fluorine is an important chemical raw material, and its compounds are widely used in aluminum smelting, coke, glass, electroplating, phosphate fertilizer, iron and steel, fertilizer, pesticide, organic synthetic chemical industry, electronics industry, atomic energy industry, as well as organic fluorine advanced lubricating oil, oxygen difluoride of rocket propellant, hydrazine fluoride, fluorine refrigerant and so on. The pollution of fluorine in the environment is harmful to human health, which is one of the most concerned and valued problems in the world.
At present, the commonly used methods of defluorination are chemical precipitation, coagulation precipitation, etc., which can quickly remove fluorine ions in wastewater, and the process is simple. Among them, chemical precipitation method has a good effect on high-concentration wastewater, but its utilization rate is low, which is easy to cause waste; The coagulation-precipitation method has the advantages of small dosage and large amount of treatment water, but the effect of fluoride removal is affected by stirring conditions and settling time, and the effluent quality is not stable enough.
In order to overcome the existing physical and chemical wastewater defluorination methods in high operating costs, harsh conditions for defluorination and other problems, Shandong Chaohua Environmental protection Intelligent Equipment Co., Ltd. has developed a new deep purification of fluorine ion complex ligand water treatment agent (biological agent JLT--005), has successfully achieved industrialization, and established a production line, can achieve large-scale production. Due to the high efficiency flocculation of biological agents at the same time, fluorine efficient purification can be achieved, and the concentration of fluoride ions in purified water is far lower than the relevant standards. The technology has the advantages of high efficiency, low investment and operation cost, simple operation, strong impact load resistance, stable effect and no secondary pollution, and can be applied to treat all kinds of fluorine-containing wastewater.
Advantages of advanced treatment of biological agents:
(1) Strong impact load resistance, efficient purification, stable operation, for wastewater with large and irregular concentration fluctuations, the concentration of fluoride ions in purified water after treatment by biological agent advanced treatment technology is stable to meet the standard requirements;
② The slag water separation effect is good, the effluent is clear and the water quality is stable;
(3) The amount of hydrolysis residue is less than that of neutralization method, and the heavy metal content is higher, which is conducive to resource utilization;
(4) The treatment facilities are conventional facilities, small footprint, low investment and construction cost, and mature technology;
⑤ Low operating cost.
