2006~2009年工业COD和SO2减排分解研究

通过运用分解模型,将工业COD和工业SO2减排分解为规模效应、结构效应、清洁技术效应和污染治理效应,并根据模型测算了2006~2009年各种效应的大小.结果表明:规模效应值为58.68%,即经济规模扩张增加工业COD和工业SO2排放,结构效应、清洁技术效应和污染治理效应效应值分别为-0.63%、-49.34%和-29.79%,即促进工业COD和工业SO2减排;分行业来看,农副食品加工业和非金属矿物制品业发展迅速,需要严格控制其发展速度;化学纤维制造业的COD产生强度和电力、热力的生产和供应业、有色金属矿采选业、石油加工、炼焦及核燃料加工业的SO2产生强度升高,需要加强清洁生产控制;燃气生产和供应业、皮革毛皮羽毛(绒)及其制品业的COD去除率和非金属矿采选业、非金属矿物制品业和燃气生产和供应业的SO2去除率降低,需要加强污染治理控制.

Decomposition analysis of COD and SO2 emission reduction of industry from 2006 to 2009

Based on the decomposition analysis, COD and SO2 emission reduction of industry was divided into scale effect, structure effect, clean technology effect and pollution control effect, and of which the effects from 2006 to 2009 were calculated. The results indicate that: first, the scale effect caused increase of COD and SO2 emission, while structure effect, clean technology effect and pollution control effect promoted reduction of COD and SO2 emission; second, agro-food processing industry and non-metallic mineral products industry should be controlled for their too fast development; third, the COD producing intensity in chemical fiber manufacturing industry and SO2 producing intensity in electricity, thermal production and supply industry,non-ferrous metal mineral industry, oil and nuclear fuel processing industry were increasing, and their clean production should be encouraged; fourth, the removing rate of COD in gas production and supply industry, leather production industry and SO2 in non-metallic mineral production industry, non-metallic mineral processing industry, gas production and supply industry were decreased, and it was necessary to strengthen its surveillance.
