摘要
就粉煤灰处理废水的研究与应用现状进行了综述。粉煤灰主要通过其吸附作用 (物理吸附和化学吸附 )处理废水 ,对于城市污水、工业废水、含重金属离子、F- 、PO3- 4废水等均有较好的处理效果。对粉煤灰进行物理或化学改性研制高效复合粉煤灰混凝剂是提高粉煤灰利用价值的有效途径之一。同时 。
The present status of research and application of fly ash in waste water treatment was summarized in this paper. The mechanism of waste water treatment of fly ash was considered as adsorption, including physical adsorption and chemical adsorption. Fly ash has good effect of treatment in domestic sewage, industrial wastewater, waste water containing heavy metal ions,. F -、PO 3- 4, etc. Developing highly efficient and complex fly-ash coagulants is one of the effective ways which can raise the utilization values of fly ash by changing physical or chemical characters of fly ash. At present, the urgent problems are how to increase the adsorption capacity of fly ash to treat saturated fly ash properly.
