Fluorine and its compounds are substances that are more harmful to humans. Fluoride and fluoride can inhibit the catalytic function of enzymes. In addition, it can also reduce serum calcium and inhibit the coagulation mechanism. Fluorine can also densify the enamel layer of teeth, thereby increasing the amount of calcium deposition. On the other hand, water-soluble fluoride is absorbed by the digestive organs and concentrated in the bones, kidneys and thyroid, and most of it is excreted in urine. Inhalation of a large amount of hydrogen fluoride or oral sodium fluoride can also cause acute poisoning.
Fluoride removal agent
In the process of industrial production, emissions from metallurgy, phosphate ore processing, phosphate fertilizer production, and coal combustion contain a large amount of fluorine, causing serious harm to the environment and humans.
The problem of fluorine pollution has attracted more and more attention, and the research on the treatment of fluorine-containing wastewater has always attracted attention in the field of environmental protection. As various industries contain
The components in fluorine wastewater are diverse and cannot be completely treated in two ways. At present, the method suitable for industrial use is mainly the precipitation method, and the others include ion exchange resin method, adsorption method, electrocoagulation method, membrane separation method and other fluoride removal methods.
Fluoride removal method
In traditional methods, companies usually use calcium salt method to reduce the concentration of fluoride ions in wastewater. Under the 1mg/L standard set by the government, the calcium salt input will not achieve the deep fluoride removal effect at all, and produce a huge amount of sludge. The pipeline is easy to foul quickly, causing various storage, cost, and equipment scrapping problems. So a deep defluoridation agent is needed.
Then it derives, for example, there is currently [email protected] Fluorine remover. It combines the traditional precipitation method and adsorption method for fluorine removal, and it is in line with the removal of fluoride in most industries, and the market price is also accepted by the public.
In response to the current national emission regulations, Shenzhen Changlong Technology Co., Ltd. has developed a highly effective defluorinating agent. It is mainly used for the deep removal of fluoride at the end of industrial wastewater, and is suitable for the deep removal of fluoride at the end of various industrial wastewaters such as coal chemical industry, electronics, electroplating, glass, surface treatment, and fertilizer. Utilizing the characteristics of high positive charge density and medium degree of polymerization of effective components, it promotes its hydroxyl sites to quickly complex with F- in wastewater to form stable compounds; at the same time, due to the decrease of positive charge density, it accelerates the aggregation and precipitation of complexes and realizes free fluorine. The conversion to granular fluorine, and then through the role of polymer flocculant bridging, capturing, etc., quickly realize the separation of mud and water, and achieve the purpose of wastewater defluorination.
At present, the company can produce and sell fluoride removal agents including solid fluoride removal agents (alkaline) and liquid fluoride removal agents (acidic) suitable for different water quality and water quality, deep fluoride removal agents, focusing on the treatment of low-concentration fluorine-containing wastewater, and the effluent stability is less than 1mg/L, with multiple functions such as fluoride removal, coagulation, and pH adjustment.
