These contain a large number of biodegradable industrial wastewater discharges into the sewage treatment plant，resulting in major biochemical reactions is difficult。which led to the sewage treatment plant is not stable run. In parts of the sewage processing plant taken some of the strengthening measures can discharge standards of COD, of NH4+，N-such as conventional pollution indicators. the emission tail water still exists a large number of difficult degradation of organic matter. these organisms continue to be in the environment are widely exist and in the biosphere. enrichment cause greater harm to the ecological environment and biological populations. According to statistics, in 2005, over 70,000 enterprises and nearly 1.6 billion tons of sewage failed to discharge standards, making nearly half of the river and 90% of urban water pollution by different degrees of refractory organic pollutants in waste water has seriously affected the economy sustainable development of society and the ecological environment of human water security. In addition, studies have shown that, even far below the emission standards for organic wastewater is still able to biological hazards and they have a lasting effect on the environment, particularly.
Therefore, we should develop efficient handling of high concentrations of refractory new sound technology for organic waste water, waste water.Refractory organic pollutants harmless to have a key role in the protection of the ecological safety has become the current country important and difficult areas of academia and the engineering of internal and external environment.
