焦作市热电厂高氟冲灰水处理方法探讨

Study of treatment for high Fluorine wastewater in the Heat and Power Plant of Jiaozuo city

针对热电厂冲灰水的高氟状况 ,在总结高氟水处理方法的基础上 ,选用两种试验方法对热电厂高氟冲灰水进行了降氟处理试验 .其理论依据是投加物质与F- 结合生成难溶性的沉淀 ,从而降低水中F- 的浓度 .试验表明CaO与KH2 PO4联合处理高氟水效果良好 ,可以达到经济处理的目的 .

It has dealt with the high Fluorine wastewter in the Heat and Power plant.Two treat*.methods have been choosen on the basis of summarizing the methods for high Fluorine water.Its theory is that what are added will combine with F - into difficultly dissolved sediment so as to reduce the concentration of F - in the water.It has found that the method of Cao+KH 2PO 4 is good for this kind of Fluorine wastewater and it also can reach the purpose of economic treatment.Meanwhile,analysis of the problems when performing the experiment have been made.
