压力-承载力-状态-响应方法的工业污染控制应用

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。

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

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 SO__2 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 SO__2 from the ceramic tile industry which is the key local industry. With environmental measures added to 26 factories, the annual SO__2 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.
