Abstract：
 The present invention is two-stage method of applying white rot fungus to degrade hard-to-degrade environment pollutant, and belongs to the field of environmental pollutant treating technology. Based on the research of the biochemical characteristic of white rot fungus, the present invention proposes intermittent running mode including two separated stages of growth and degradation. The present invention adopts high temperature culture and normal temperature degradation, agricultural waste corn cob and timber as nutrients source, high nutrients concentration for growth and low nutrients concentration for degradation and natural ventilation in growth stage, and thus has low power consumption and low cost. Adding carrier can maintain higher exocellular enzyme concentration, speed reaction, maintain higher decolorizing efficiency and separate mud from water. The present invention has good oxygen supply, good hydraulics characteristic and high hetero bacteria pollution resistance.
