污水处理设施建设与运营模式浅析

详细介绍了国外污水处理设施建设与运营的管理经验,分析了英国、美国、法国和荷兰等典型管理模式的特点,阐述了中国污水处理事业的发展历程,调研了目前国内并存的事业体制、企业化管理、委托运营、DBO（设计-建设-运营）、特许经营、股权转让、合资合作、完全私有化、用户和社区资助等模式并逐一进行分析,指出了中国污水处理设施建设与运营的发展方向,认为应尽量慎重考虑涉及产权的特许经营模式,着力推广DBO模式。     

碳排放交易制度下城市减排的机会成本研究——基于中国碳排放试点城市的实证检验

作为全球气候治理的重要手段,碳排放交易制度受到了广泛的关注与讨论。基于此,本文采用我国2010-2016年城市面板数据,运用非参数方法构建方向性环境距离函数测算了2009-2015年城市减排的机会成本,计算结果显示,试点地区与非试点地区的碳排放的机会成本整体表现为上升的趋势,且试点地区的碳排放的机会成本总体低于非试点地区。在测算城市减排机会成本的基础上,运用双重差分法来检验碳排放交易制度的有效性。经检验发现：碳排放交易制度有利于降低城市减排的机会成本,然而由于碳排放交易制度还存在碳排放权初始分配制度缺失、碳排放交易制度的定价机制扭曲等问题,因此其对降低城市减排的机会成本作用较小,并且进一步通过对政策时间趋势的分析得出政策效应随时间推移而逐渐减弱。     

某皮革厂皮革废水处理工程案例分析

皮革废水属于高浓度难降解有机工业废水,具有排放水量大、水质水量不均、污染物成分复杂等特点,给皮革废水处理带来极大的难度。以河北省辛集市某皮革厂废水处理工程为例,简要描述了该皮革厂皮革的生产工序、废水水量及水质特征,重点论述了皮革废水的处理方法、投资费用、运行费用及运行效果,并对该工艺所采用的理念、方法及效果进行了探讨。     

电解铝行业清洁生产实践

概述了电解铝行业清洁生产实践,分析说明企业实施清洁生产后,能够达到污染减排、节能降耗、提高企业经济效益的目的。     

用边际费用分析方法研究制定排污收费的新标准

排污收费的有效性主要取决于它的经济刺激作用。本文分析了排污收费的经济学原理,提出了制定排污收费标准更为合理有效的方法──边际费用分析法,定量地描述和分析了排污收费与其经济刺激作用的关系,以天津纪庄子污水处理厂为例,提出应建立的排污收费标准。本文指出,有效地运用排污收费来管理污水的排放,必须实行区域总量控制,制定具有有效的经济刺激作用的排污收费标准。

INTEGRATING SOCIAL BENEFIT COST ACCOUNTING INTO WATERSHED RESTORATION AND PROTECTION PROGRAMS1

ABSTRACT: Successful watershed management requires consideration of multiple objectives and the efficient use of scarce public and private resources. One way to address these multi-faceted issues is through Social Benefit-Cost Accounting (SBCA). SBCA is a systematic method of addressing complex social and economic issues relevant to proposed watershed management projects. Benefits of using this technique include: benefits and costs of watershed projects are better understood; politically sensitive issues tend to be put into perspective; and stakeholders' interests are placed on a level playing field. An example from Bogota, Colombia demonstrates how SBCA can be used to value the benefits and costs of a proposed project. By addressing the benefits and costs to all stakeholders, the design of watershed management programs can be improved to achieve goals in a cost-effective manner.     

A COST‐BENEFIT ANALYSIS OF WATER QUALITY PROTECTION IN THE CATAWBA BASIN1

ABSTRACT: The primary objective of this study was to perform a cost‐benefit analysis of maintaining the current level of water quality in the Catawba River basin. Economic benefits were estimated using a stated preference survey method designed to value respondents' willingness to pay for a management plan to protect water quality in the Catawba basin over time. From the surveys conducted with 1,085 area residents, we calculated an annual mean willingness to pay of $139 for the management plan, or more than $75.4 million for all taxpayers in the area. Over the five‐year time horizon in which respondents were asked to pay for the management plan, this resulted in a total economic benefit of $340.1 million. The Watershed Analysis Risk Management Framework model was used to estimate the amount of management activities needed to protect the current level of water quality in the basin over time. Based on the model results, the total cost of the management plan was calculated to be $244.8 million over a ten‐year period. The resulting cost‐benefit analysis indicated that the potential benefits of this management plan would outweigh the costs by more than $95 million.
