Research on Solid Waste Disposal and Comprehensive Utilization Under the Background of"Waste Free City"——A Case Study of Bijie City
Based on the background of"waste free city",the status quo of solid waste disposal was analyzed,and the comprehensive management measures were analyzed in combination with the actual situation.Taking Bijie City of Guizhou Province as an example,the sources,production and pollution control of solid waste in 2022 were analyzed.In 2022,the bulk industrial solid waste,industrial hazardous waste,medical waste and municipal solid waste were all treated as resources and harmless in strict accordance with the requirements,and the comprehensive utilization rate of bulk industrial solid waste was 75.02％.The disposal rate of industrial hazardous waste is 83.26％.The utilization rate is 15.36％.The storage rate is 1.38％.The centralized harmless disposal rate of medical waste is 8,400.2 tons,and the centralized harmless disposal rate is 100％.The harmless treatment rate of household garbage was 87.05％,and the coverage rate of rural garbage collection and transportation facilities reached 97.8％.To investigate the output of solid waste in Bijie City from 2018 to 2022,the output of solid waste gradually in-creased,and the solid waste in 2022 increased by 13.09％compared with that in 2018;From 2018 to 2022,the comprehensive utilization rate of solid waste in Bijie City gradually increased,and the comprehensive utilization rate of solid waste in 2022 increased by 31.15％compared with 2018.Bijie City actively responds to the develop-ment requirements of"waste free city".Combined with the status quo of solid waste treatment,from the active technological innovation,improvement of solid waste disposal,establishment of a solid waste disposal center and other aspects,treatment of solid waste is timely achieved;the reduction of municipal solid waste is achieved;the overall disposal level is improved,and urbanization development is promoted.
