压力承载力状态响应方法的工业污染控制应用

Pressure-carrying capacity-state-response method for analyzing industrial pollution control

为了探究环境承载力对区域污染控制的影响,在传统的压力状态响应框架基础上,引入承载力因子,提出压力承载力状态响应分析方法。将该方法应用于工业SO2污染控制研究。案例研究表明,某镇建筑陶瓷业造成的SO2污染压力分布与承载力分布状况非常不均衡,导致该镇SO2年均浓度超过国家环境空气质量二级标准。选择了26家企业,它们综合采取清洁生产及脱硫设施等响应措施,SO2的削减量将达到12kt/a。其中,由清洁能源替代形成的削减量为6.8kt/a;新建脱硫设施形成的削减量为5.2kt/a。

To explore the influence of environmental carrying capacity on regional pollution control, a carrying capacity factor was added to the traditional pressure-state-response （PSR） method to develop a pressure-carrying capacity-state-response （PCSR） method. The method was applied to analyze industrial sulfur dioxide pollution control methods in a town in southern China where the local annual average concentration of SO2 exceeds the second level of the national ambient air quality standard. The results indicate a large imbalance between the natural carrying capacity and the pressure caused by the SO2 from the ceramic tile industry which is the key local industry. With environmental measures added to 26 factories, the annual SO2 reduction would be 12 kt, in which the reduction due to cleaner energy alternatives would be 6.8 kt/a and the reduction due to new desulfurization facilities would be 5.2 kt/a.
