工业锅炉PM2.5产排特性试验研究

采用荷电低压颗粒撞击器(ELPI)对哈尔滨市两台燃用烟煤的工业锅炉PM2.5排放特性进行了研究.研究结果表明:PM2.5的粒数和质量浓度分布曲线均呈现单峰分布,前者峰值出现在0.12~0.2μm粒径范围内,这部分粒子主要是由无机物气化-凝结形成的亚微米颗粒物和挥发分未完全燃烧形成的炭黑粒子,而后者峰值出现在0.32μm处,粒子主要是由炭黑粒子形成的亚微米颗粒和残灰粒子形成的超微米颗粒.同时发现,旋风除尘和湿法除尘对PM2.5各级颗粒均有一定的去除效果,采用多管旋风和冲击水浴除尘器联合除尘效率比单种水膜除尘器除尘效率高;湿法脱硫系统对PM2.5的脱除也有明显的作用,由于除雾器不能全部去除小雾滴,这些雾滴中固体颗粒被干燥和水溶性物质结晶析出,PM0.32颗粒物粒数浓度有所增加,而PM0.32~2.5的颗粒物粒数浓度有所减少,但总质量浓度降低.

卤系阻燃剂在东江工业水体中的质量浓度及其分配特征

本研究分析了东江工业水体中卤系阻燃剂的浓度,组成分布以及分配特征.结果表明多溴联苯醚(PBDEs)是水体中的主要的卤系阻燃剂,占总卤系阻燃剂的41.0%,其质量浓度范围为1 102.3~3 666.9 pg·L~(-1),其中BDE209是颗粒相的主要成分.四溴双酚A(TBBPA)占总卤系阻燃剂的32.4%,其质量浓度范围为1 120.9~2 856.5 pg·L~(-1),其他卤系阻燃剂如十溴二苯乙烷(DBDPE)、德克隆(DP)和六溴环十二烷(HBCDs)分别占总卤系阻燃剂的16.3%、7.3%和3.0%,其质量浓度范围分别为397.7~1 736.8、235.7~778.1和9.5~266.8 pg·L~(-1).在对水体溶解相和颗粒相分配的研究中发现,PBDEs、DBDPE、DP和HBCDs主要存在于水体颗粒相中,而TBBPA由于其较大的水溶性,主要存在于溶解相中;卤系阻燃剂的lgK_(oc)与lgK_(ow)之间存在显著的相关性,但是lgK_(oc)实测值与其理论预测值有一定差异,这可能是受控于悬浮颗粒(SPM)含量和溶解有机碳(DOC)含量这两个因素,此外,颗粒相和溶解相之间分配是否达到平衡也是影响测量lg Koc值的因素.     

Suspended Particulate Matter Distribution in Rural-Industrial Satna and in Urban-Industrial South Delhi

An air quality sampling program was designed and implemented to collect the baseline concentrations of respirable suspended particulates (RSP = PM₁₀), non-respirable suspended particulates (NRSP) and fine suspended particulates (FSP = PM_2.5). Over a three-week period, a 24-h average concentrations were calculated from the samples collected at an industrial site in Southern Delhi and compared to datasets collected in Satna by Envirotech Limited, Okhla, Delhi in order to establish the characteristic difference in emission patterns. PM_2.5, PM₁₀, and total suspended particulates (TSP) concentrations at Satna were 20.5 ± 6.0, 102.1 ± 41.1, and 387.6 ± 222.4 μg m⁻³ and at Delhi were 126.7 ± 28.6, 268.6 ± 39.1, and 687.7 ± 117.4 μg m⁻³. Values at Delhi were well above the standard limit for 24-h PM_2.5 United States National Ambient Air Quality Standards (USNAAQS; 65 μg m⁻³), while values at Satna were under the standard limit. Results were compared with various worldwide studies. These comparisons suggest an immediate need for the promulgation of new PM_2.5 standards. The position of PM₁₀ in Delhi is drastic and needs an immediate attention. PM₁₀ levels at Delhi were also well above the standard limit for 24-h PM₁₀ National Ambient Air Quality Standards (NAAQS; 150 μg m⁻³), while levels at Satna remained under the standard limit. PM_2.5/PM₁₀ values were also calculated to determine PM_2.5 contribution. At Satna, PM_2.5 contribution to PM₁₀ was only 20% compared to 47% in Delhi. TSP values at Delhi were well above, while TSP values at Satna were under, the standard limit for 24-h TSP NAAQS (500 μg m⁻³). At Satna, the PM₁₀ contribution to TSP was only 26% compared to 39% in Delhi. The correlation between PM₁₀, PM_2.5, and TSP were also calculated in order to gain an insight to their sources. Both in Satna and in Delhi, none of the sources was dominant a varied pattern of emissions was obtained, showing the presence of heterogeneous emission density and that nonrespirable suspended particulate (NRSP) formed the greatest part of the particulate load.     

RETRACTED ARTICLE: Environmental Impact Assessment of Industrial Structure Change in a Rural Region of China

As the embodiment of human activities, the change of regional industrial structure is an essential driving factor of global environmental change. Consequently, the research on the change of regional industrial structure and associated effects on the environment is one of the key issues of researches on sustainable development, human–environment relationship, and regional response to global environment change. However, compared to the flourish of researches on environmental impact assessment of industrial departments, few studies have been conducted to assess the environmental impact of regional industrial structure. In this study, based on a synthetic analysis of environmental disturbances of different industrial departments, the environmental impact coefficient of industrial department associated with the index of environmental impact of industrial structure was constructed, so as to make a quantitative assessment of environmental impact of the change of regional industrial structure. And the results of the case study in Lijiang City, a rural region of China, have showed that there are two obvious changes of industrial structure in the study area from 1992 to 2003, associated with a continuous decreasing of the index of environmental impact of industrial structure, which indicated a positive environmental effects of the change of regional industrial structure.

基于工业生态化建设的工业园区环境管理研究

工业园区是产业集聚的载体,是区域经济发展的引擎。工业园区同时又是污染产生排放集中地,我国工业园区在发展过程中随着经济总量扩大、资源和能源消耗的增加,出现了大量的环境问题,阻碍了园区的可持续发展。工业园区的环境管理可以从园区层面出发解决污染问题,这是个既复杂又重要的工作。本文在分析工业园区发展历程的基础上揭示了目前工业园区存在的环境问题,以及管理方面存在的缺陷和不足,发现总体上园区环境管理水平较差。工业生态化建设为进行合理的园区环境管理提供了一个契机,本文针对我国工业园区的发展现状及发展趋势,提出基于工业生态化建设的工业园区环境管理的对策:1提升生态工业的意识,鼓励公众参与;2确立生态化建设思想,以生态化建设促进环境管理效率的提升;3加强工业生态化建设相关政策法规、规划的完善和实施;4构建工业生态化建设信息服务平台,以生态化建设来实现工业园区科学的环境管理。     

化工园区突发环境事件应急预案编制的研究

我国的化工园区为促进经济和社会发展做出了重要贡献。由于化工园区内危险化学品种类多、有毒有害物质数量大、环境风险等级高,存在着发生重特大事故的现实性和可能性。但是,我国至今尚未制定化工园区突发环境事件应急预案编制技术规范,相关研究也未见报道。在当前化工园区安全生产事件高发并严重影响周边环境的情况下,研究化工园区突发环境事件应急预案编制方法,提高应对安全生产事故以及次生突发环境事件的能力尤为重要。通过分析化工园区环境风险物质、环境风险工艺和环境风险受体三个方面的环境风险的特性,初步拟定了化工园区突发环境事件应急预案编制调查评估、建章立制、预案编写三个阶段的技术路线,明确了开展环境风险评估、加强应急能力建设、完善环境风险防范措施和环境应急处置措施的四项编制要点,在此基础上提出了化工园区突发环境事件应急预案由综合预案、现场处置预案、专项预案、环境风险评估报告、环境应急资源调查报告六部分组成的结构框架。
