Abstract
Steam boilers have been applied in various industries,but has problems such as high resource waste rate and serious emissions pollution.To address this problem,an energy-saving and emission reduction scheme based on phosphorus free water treatment technology was proposed and applied to the energy-saving and emission reduction of steam boilers in printing and dyeing enterprises.Simulation experiments were conducted on phosphorus free water treat-ment technology.The results showed that the compliance rate of various indicators in the discharge of wastewater treated with this technology was 100%,the phosphorus mass concentration was reduced to 0.000 1 mg/L,and the mass concentra-tions of mercury and acute toxicity of wastewater were reduced to 0 mg/L.The effectiveness of energy-saving and emission reduction scheme using this technology in the printing and dyeing industry was further analyzed.The results showed that af-ter using this scheme,the natural gas consumption,sewage discharge,boiler water preparation cost,and phosphate dosage of the steam boiler were significantly reduced every quarter.The energy-saving and emission reduction scheme based on phosphorus free water treatment technology can reduce the energy consumption of steam boilers,decrease sewage dis-charge,and reduce the usage costs.关键词
