Fluorine sodium silicate factory - about the present situation of sewage treatment Appropriate chemical industry
dosage of fluorine sodium silicate in the building materials industry is very big, the fluorine sodium silicate manufacturers in the production of sodium fluosilicate method with sodium sulfate and sodium chloride method, the two methods in production will produce large amounts of sewage, fluorine sodium silicate manufacturers how to deal with the sewage becomes one of the more important question.
usually, fluorine sodium silicate manufacturer to produce sodium sulfate method of sewage are mainly root, fluosilicate and sodium sulfate, and sodium chloride method is used to mainly, sodium fluosilicate roots and chloride ions, the two methods of sewage no acid, corrosion resistance is very strong, if not handled will cause serious pollution to the environment. Fluorine sodium silicate manufacturers therefore steps of sewage processing is must. at present, some sodium fluosilicate manufacturer will wastewater to produce phosphoric acid, but because the sodium ion content in the wastewater is higher, so can't normal use, some fluorine sodium silicate factory sewage main neutralization with lime emulsion, and through two-stage sedimentation separation, realize the solid-liquid separation. This method, wastewater after treated with lime water fluorine ion and calcium ion concentration and PH of solution, sodium fluosilicate manufacturers therefore reduce the acidity of the water, increase the PH of the solution, improve the concentration of calcium ions, reducing water fluoride ion concentration. That is to say, the fluorine sodium silicate manufacturer in order to ensure the fluoride ion in water, the water PH and the concentration of calcium ions must meet the matching conditions, but in the process of operation, the concentration of calcium ions is often not enough, test shows that the PH of 10 - 11, fluorine for best results. sodium fluosilicate manufacturer for sewage treatment has never interrupted, but reasonable and economical wastewater treatment method has no immediate, need further research of mining.
