Research Status and Countermeasures of photocatalyst in Water Pollution Treatment

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