Abstract: A constructed wetland system enhanced by immobilized laccase, it includes wetland plants, a matrix layer and a water distribution system, the wetland plants growing on the matrix layers, the matrix layer including a laccase catalyst and gravel, the laccase catalyst and gravel are distributed at intervals in a modular manner in a ratio of 1:5, the water distribution system is arranged on both sides of the matrix layer. The laccase catalyst is prepared by using a co-immobilization technology. The system improves the removal effect of hard-to-degrade organic matter in wastewater, and solves the problems of toxicity and stress of the hard-to-degrade organic matter existing in the prior art and the problems of matrix adsorption saturation.
