Research Status and Countermeasures of photocatalyst in Water Pollution Treatment

Abstract

With economic development and population growth, the demand for fresh water resources is also increasing. However, affected by sewage discharge from industry, agriculture, mining and domestic, not only the ecological environment and natural resources are seriously damaged, but also the water resources available for people to drink are decreasing day by day. How to improve the water pollution treatment technology has become an urgent task. Because of the high cost and great limitation, the traditional treatment method has no significant effect in water pollution control. As an advanced oxidation technology, photocatalyst can effectively degrade pollutants in water pollution, and has a positive effect on improving water quality, protecting natural resources and maintaining ecological balance.
