摘要： A system that relates to the technical field of sewage purification includes microalgae culturing pond and constructed wetland that are connected in series. A microalgae capturing filler is arranged in the microalgae culturing pond, algae-containing water obtained from microalgae capturing filler is communicated with the constructed wetland for oxygen transfer and forming algal-bacterial mutualistic symbiosis for strengthened pollutant removal, and part of captured microalgae is introduced into an anoxic denitrification functional area away from a surface in constructed wetland by flow guide pipe. Microalgae culture and sewage purification are realized in microalgae culturing pond by taking sewage as a culture medium, 80% or more of the microalgae biomasses in microalgae culturing pond are recovered with low cost, part of microalgae is introduced into the anoxic denitrification functional area away from the surface in the constructed wetland, and lytic algae cells serving as a carbon source promote denitrification in the wetland.

摘要： 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.
