Research advances on the High-strength Organic Wastewater Treatment

摘要

With the development of chemical and related industry, the quantity of high-strength organic wastewater is growing, which could cause a bigger threat to human health, so it becomes very urgent and essential to research and develop new applicable wastewater treatment technology. The treatment techniques of high-strength organic wastewater at home and abroad were summarized: physical and chemical methods, biological methods and the combined process. The technological process, characters and principle of every method were introduced. These wastewater treatment technologies have some advantages of completely mineralization and degradation of the pollutants, and low risk of secondary pollution. They also have many disadvantages of complex technological process and higher operating cost. Finally, the direction of the research on two-phase combined process was pointed out.
