摘要
进行了粉煤灰处理含氟工业废水的多项条件试验.给果表明,粉煤灰可大幅度降低废水的含氟量.同时使废水pH值得到调整.水中P、COD、SS值也有一定降低.对除氟后的粉煤灰,建议制成各种固化砌块适当利用.
Removal of fluoride from industrial wastewater by fly ash was tested. The results demonstrated that fluoride was reduced significantly by fly ash. At the same time, pH value of wastewater was adjusted, COD, SS, and P were reduced as well. Both capital and operation cost were lower than those of traditional technology of lime sedimentation. Possible secondary pollution of the procedure was discussed as well.
