摘要
“推进中国清洁生产”项目（Ｂ－４子项目），在２７家企业开展了２９轮清洁生产审计，共发现６９０项清洁生产技术。本文将６９０项清洁生产技术按投资量分为无／低费和设备更新技术，并对这两项技术进行了成本效果分析，发现无／低费技术平均每１００００元投资削减ＣＯＤ５４２ｔ／ａ，创经济效益１０１６万元／ａ；设备更新技术平均每１００００元投资削减ＣＯＤ０６０ｔ／ａ，创经济效益０９１万元／ａ（以净现值计）；无／低费技术的投资偿还期平均为４０个月，设备更新技术的投资偿还期平均为４００个月。
The project Promoting Cleaner Production in China (sub-project B-4) conducted 29 cleaner production (CP) audits in 27 enterprises and identified 690 CP technologies.This paper divides 690 CP technologies into 2 categories,i.e.non/low cost options and equipment renovation options according to their investment.A cost-benefit analysis indicates that non/low cost options,in average,reduce COD by 5.4t/a and generate economic benefits by 101600 Yuan RMB/a for 1,000 Yuan RMB investment,and their average pay-back period is 4.0 months;equipment renovation options,in average,reduce COD by 0.060 t/a and generate economic benefits by 910 Yuan RMB/a (in terms of Net Profit Value) for 1000 Yuan RMB investment,and their average pay-back period is 40.0 months.
