摘要： Constructed wetland has been widely applied in treating a variety of wastewater. The aquaculture wastewater from fish pond was purified by compound eco-ditch which is based on the simple transformation of general ditch. The results showed that: 1) After aquaculture wastewater passing through the compound eco-ditch, the quality of it is obviously improved with DO increasing but TN, TP, NH3-N NH4+N and CODMn decreasing. 2) The removal rate of the compound eco-ditch for aquaculture wastewater has a significant correlation with the flow path and initial concentration, and it is increased with the increase of the initial concentration within a certain range. Preliminary results show that compound eco-ditch used in aquaculture wastewater treatment and recycling has broad prospects.
