摘要：

Aimed at the issue of dissolved oxygen concentration insufficiency in regular constructed wetlands, shale hollow bricks are adopted to build self-aeration constructed wetlands, to increase the oxygen supply capacity in the system. The experimental result indicates that DO concentration in self-aeration constructed wetlands is 0.1mg/L higher than that in artificially intensified aeration wetlands, and the removal rate for COD reaches over 85%,which is about 2% higher than that of artificial aeration wetlands. This shows that the built self-aeration constructed wetland system can increase oxygen supply capacity in the wetland, and increase the purification efficiency of the wetland system for COD in wastewater.
