H酸综合废水治理工艺试验研究及工程应用

针对H酸母液及T酸一次洗水高含盐量有机废水进行系统的实验研究，结果表明：废水经冷却、结晶、过滤后，用铁屑过滤，石灰乳、PAM处理．使废水COD去除率为50％，脱色率为7O％，BOD／CODcr提高到0．2以上，预期COD去除率达60％以上，BOD去除率达85％以上，NH3—N去除率达80％以上．     

生物滴滤池法处理废气动力学模式研究

基于物料平衡和微生物降解废水中污染物的动力学模式,以丙酮、甲苯为处理对象提出了生物滴滤池处理废气的模式。当入口浓度C_(in)较低,小于临界浓度C_(crit),时,C=C_(in)EXP((-B/V_g)·H);当人口浓度C_(in)较高,大于临界浓度C_(crit)时,C=C_(in)-(K_0X/V_g)·H。研究表明,实验结果与模式计算结果吻合较好。     

气候政策研究中的数学模型评述

按照成本分析和综合分析2个层次，分别介绍了投入产出模型、可计算一般均衡模型、宏观计量经济模型、工程经济模型、动态能源优化模型、能源系统模拟模型、综合评估模型等不同模型方法的特点及其在气候政策分析中的应用。指出可计算一般均衡模型是应用得最为广泛的方法之一。概括了气候政策模型研究的4个发展趋势，包括加强综合评估模型的应用、扩展成本与效益的内涵、注重不同模型之间的比较、强调不确定性分析。结果中国研究现状，分析了当前面昨的问题，认为国内气候政策模型研究与中国在国际气候变化领域的地位仍不相称，强度要进一步加强研究队伍建设、扩展研究领域、跟踪国际研究前沿问题，以便为国家的气候谈判政策提供更有效的科学依据和决策支持。

Biogenic VOCs emission inventory development of temperate grassland vegetation in Xilin River basin, Inner Mongolia, China

Given the key role of biogenic volatile organic compounds(VOCs) to tropospheric chemistry and regional air quality, it is important to generate accurateVOCs emission inventories. However, only a less fraction of plant species, in temperate grassland of Inner Mongolia, has been characterized by quantitative measurements. A taxonomic methodology, which assigns VOCs measurements to unmeasured species, is an applicable and inexpensive alternation for extensive VOCs emission survey, although data are needed for additional plant families and genera to further validate the taxonomic approach in grassland vegetation. In this experiment, VOCs emission rates of 178 plant species were measured with a portable photoionization detector( PID). The results showed the most of genera and some families have consistent feature of their VOCs emission, especially for isoprene, and provide the basic premise of taxonomic methodology to develop VOCs emission inventories for temperate grassland. Then, the taxonomic methodology was introduced into assigning emission rate to other 96 species, which no measured emission rates available here. A systematical emission inventory of temperate grassland vegetation in Inner Mongolia was provided and further evidence that taxonomy relationship can serve as a useful guide for generalizing the emissions behavior of many, but not all, plant families and genera to grassland vegetation.

Methods for project-based mechanisms (JI/CDM)—relevance of IPCC inventory guidelines

A baseline for a project consists of estimates of annual emissions of greenhouse gases (GHG) for a given time period without implementing the project. A general three-step process for determining the baseline is suggested. The emission reduction of the project is given by the difference between the baseline and the monitored annual emissions. A preferred method, direct measurement of the emission reduction, is possible for some types of projects. Methods for estimating the annual baseline emissions are not necessary for the latter category, and a definition of this project category is suggested. IPCC Guidelines for National GHG Inventories categorise the emission sources so that only direct emissions from consumption of fuel and feedstock are calculated. There are thus no emission factors for indirect emissions (e.g. electricity consumption or km transported) or emission factors that depend on technology only, independent of consumption of fuel and feedstock. Technology-dependent emission factors may thus need to be developed for estimating indirect emissions and multi-project baselines. Consistency should be sought with the IPCC Guidelines when estimating annual baseline emissions and in monitoring project emissions to ensure comparability with the National Inventories.     

刍议排污权价格的合理界定

排污权交易在中国的试点过程中,显现了强大的生命力,然而,由于对排污权交易基础理论理解的偏差,导致了实践层面上的缺陷,如排污权初始分配是否应该有偿的问题;排污权商品再分配价格应不应该包括正的外部效应价值问题;在排污权交易制度改革与中国其他制度的改革(现行税制改革、绿色GDP的推行)进行中出现的不协调的问题.
