Harmless Treatment of Metal Smelting Wastewater With Fluoride Removal Agent
Metal smelting wastewater is iron, steelmaking, rolling process of cooling water and the casting, rolling water, in the smelter wastewater discharged into nature, part is absorbed by the water, part of the material is adsorbed to colloidal or particles, after a long time after aggregation, gradually settle to the bottom of the water position. Influenced by the surrounding environmental factors, the solubility will also change, with great differences in summer and winter. The harm of smelter wastewater mainly consists of two aspects, on the one hand, it is the harm to human body, on the other hand, it is the pollution to the environment, so the discharged wastewater should be treated harmlessly.
In the treatment process, fluoride remover can be used in fluoride removal in metal smelting wastewater. It is a composite cationic inorganic polymer flocculant with aluminum ion as the core, mainly through coordination exchange, adsorption, ion exchange, complexation precipitation and other mechanisms, forming precipitation so as to achieve the purpose of removing fluoride in wastewater.
Fluorine removal agent has high strength of fluorine removal, multiple effects such as fluoride removal, coagulation, and pH regulation, and accelerate precipitation. It is a special needle coal chemical industry, semiconductor industry, non-ferrous metals and rare earth smelting, mine wastewater and other fluorine wastewater treatment and special research and development of a new chemical agent.
The use of metal smelting wastewater fluoride removal agent is more environmentally friendly, but also more convenient. High purity, less impurities, low sludge volume, will not increase water COD, TN, TP pollutants, no free aluminum ions, sludge filter water has no impact on biochemistry, tasteless, clear water after treatment; without changing the original treatment process, without adding large water treatment structures, adding can be effective, without complex debugging and easy operation.
