Research on phosphorus removal by non-metallic mineral in wastewater treatment

In order to solve the environmental pollution caused by phosphorus wastewater, research on treatment of phosphorus wastewater by non-metallic mineral such as zeolite, bentonite, attapulgite, sepiolite and vermiculite was summarized. The results show that treatment of phosphorus wastewater by non-metallic mineral has the characteristic of simple in process, good effect and lower operation cost. And this process has expansive application foreground. The problems remained were pointed out. Further research on the mechanism of wastewater treatment with non-metallic mineral, separation and final utilization of the saturated non-metallic mineral are needed to do in the near future.
