优化能源结构 改善宣城市大气环境质量

通过对宣城市能源结构和大气环境质量现状的分析,提高了天然气、电能和太阳能等清洁能源在能源结构中的比例,并运用城市多源扩散模式进行浓度预测.结果表明:采取清洁能源替代措施以后,大气中的二氧化氮和二氧化硫按功能区划分均可达到相应的国家标准.

Optimization of Energy Structure to Improve Air Environmental Quality

With the Xuancheng city,rapid industrial growth, urban air quality tends to deteriorate. Despite the increased sewage treatment units, so that the air quality to some extent changed. However,in order to fundamentally alter the atmospheric quality of the environment, we must start from the source, optimizing the energy structure. Xuancheng city of energy structure and atmospheric environmental quality analysis,raise the gas, electric and solar energy and other clean energy in the energy mix of proportion,and the use of city-proliferation of multi-source model concentration predicted. The results showed that adopt clean energy alternatives,atmospheric nitrogen dioxide and sulfur dioxide by functional area can be divided accordingly to achieve national standards.
