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 ...
