Abstract: In order to solve the current water pollution problem caused by industrial wastewater, the purification mechanism of aquatic garden plants on industrial wastewater is analysed and studied. The treatment process and influencing factors of plants in the purification process are analysed separately, and the purification mechanism of aquatic garden plants on different pollutant components in industrial wastewater is derived from a theoretical perspective. In order to verify the analysis results of the purification mechanism, the actual measurement analysis experiment of the purification effect of aquatic garden plants on industrial wastewater was designed. The experimental results show that aquatic garden plants can effectively reduce the content of TN, TP, COD, NH4+-N and heavy metals in industrial wastewater, and therefore have a high purification effect on industrial wastewater. Among a variety of aquatic garden plants, water onions and Canna's purifying effect is more obvious, and the removal rate can reach 83%.
