At present,the wastewater treatment problem of water purification plant is becoming increasingly severe,which poses a major challenge to environmental protection and sustainable development.In order to solve this problem,this study deeply discusses the related technologies and comprehensive evaluation methods of wastewater treatment.Through chemical precipitation,microbial treatment,physical adsorption and other technical means,the impact of wastewater on the environment is effectively reduced.At the same time,the multi-index evaluation method was used to adjust the weights according to the actual situation to comprehensively evaluate the treatment effect.The results show that the comprehensive treatment technology significantly improves the quality of wastewater,and the indicators such as COD and BOD are significantly improved,which is better than that of the single treatment technology,which provides an effective solution for the wastewater treatment of water purification plants.The comprehensive evaluation method constructed in this study can accurately and comprehensively evaluate the wastewater treatment effect of water purification plant engineering,provide reference for decision-makers and guide the subsequent optimization of the treatment process.
