Research on Clean Production Audit of Enterprises for Collaborative Disposal of Solid Waste in Cement Production
Conducting clean production audits is an objective requirement for cement production enterprises to achieve green development,which helps to strengthen source control and prevent pollution throughout the entire process.Taking a cement production enterprise in Linyi City as an example,this paper analyzes the clean production audit of enterprises for the collaborative disposal of solid waste in cement production.The current round of clean production audit of the enterprise has generated a total of 3 no/low cost plans and 7 medium/high cost plans,with a total investment of approximately 27.07 million yuan.After the full implementation of the plans,the power consumption per unit product decreases by 1.1%,the production of nitrogen oxides(NOx)per unit product decreases by 3%,and the production of sulfur dioxide per unit product decreases by 21.7%,all of which achieve the preset clean production goals.Through this round of clean production audit,the enterprise can generate an annual economic benefit of 4.63 million yuan,save 4 100 t of coal and 2.62 million kW·h of electricity,reduce 11.8 t of sulfur dioxide emissions,50.4 t of chloride ion emissions,25.1 t of NOx emissions,and 1.1 t of dust emissions,it has reached the first class of clean production level specified in the"Cement Industry Clean Production Evaluation Index System(Trial)".Practice has shown that this round of clean production audits has produced significant economic and environmental benefits.
