摘    要:环保类项目主要价值体现为环境效益,清洁生产中高费方案分析中,单纯分析经济费用效益,经常为不可行方案.文章以污水处理厂3个不同的清洁生产方案(增加化学除磷、污泥深度脱水、增加除臭设施)为例,对他们的环境效益进行了货币化估值,并将AHP确定权重的方法引入环境影响货币化估值中,对纳入环境价值的方案分析其内部收益率,从而分析清洁生产中方案的可行性.分析得出化学除磷和污泥深度脱水的内部收益率分别为12.89%和13.54%,具有可行性,因此优选实施污泥深度脱水方案.

关 键 词:环境价值  层次分析(AHP)  清洁生产

Abstract:Environmental protection projects are mainly beneficial to environment quality of surrounding area. The financial analyses of those areas are inadequate without taking environmental valuation into account. There are three cleaner production op-tions for wastewater treatment plants, i. e. chemical phosphorus removal, advanced sludge dewatering, deodorization. In the pa-per environmental benefits of CP options are monetized, and then are converted by weighted coefficient of analytic hierarchy process( AHP) . Cleaner production options are judged based on the internal rate of return with considering environmental valua-tion, whether are feasible. The IRRs considered environmental valuation of chemical phosphorus removal and advanced sludge de-watering are respectively 12. 89%and 13. 54%. Advanced sludge dewatering is optimum project.
Keywords:Environmental valuation  analytic hierarchy process( AHP)  cleaner production
