织物干洗的工业生态研究

正确评价干洗剂对人体的毒副作用，合理地设定干洗过程挥发性有害物质的残留限量，是开发干洗业环境无害技术和绿色服务的先决条件。只有在充分保证环境安全的前提下，通过逐步推行化学清洁产品的总体选择战略，从环境管理和经济发展的结合上来规范企业的环境行为，才能最终实现干洗业的可持续发展。     

清洁生产及其在瑞丽糖厂的实践

瑞丽糖厂从吸滤，发酵，酒精废醪液利用等方面实施清洁生产方案，从源头控制和减少污染物的产生，日排废水减少21792m^2,CODCr消减率达到85．9％，污染得到了有效控制。     

Can Forest-protection carbon projects improve rural livelihoods? Analysis of the Noel Kempff Mercado climate action project,Bolivia

We studied the Noel KempffMercado Climate Action Project (NKMCAP),Bolivia, to assess whether forestprotection carbon (C) projects cansignificantly benefit local people. Wehypothesized that forest protection canonly securely deliver C if significantstakeholders are meaningfully andtransparently involved, traditional orcustomary rights are recognized and theirloss compensated for, and there are directlinkages between conservation anddevelopment objective. Our researchfocused on 53 members of the communities ofFlorida, Porvenir and Piso Firme and 36secondary stakeholders. In each of thevillages we held half-day meetings withcommunity leaders, complemented bysemi-structured one-hour interviews with 5,10, and 7 families, representing 20%, 10%and 8% of each community. The long-termimpact of the NKMCAP on the localcommunities may well be positive. However,in the short run, certain sections of thelocal communities are financially poorer. Forest protection projects clearly have thepotential to sequester C, protectbiodiversity and simultaneously contributeto sustainable rural development, but ifthey really are to improve rurallivelihoods, they must be designed andimplemented carefully and participatively.     

清洁生产在制药企业中的实施

清洁生产是一种全新的发展战略,是环境保护战略具有重大意义的创新,是工业发展的必然选择,对制药企业清洁生产由为重要.随着企业不断的发展,生产规模不断的扩大,污水处理厂的能力接近饱和,已没有扩展的空间,这时,清洁生产由为重要,势在必行.     

清洁生产是发展云南磷肥工业的必由之路

云南磷矿储量占全国总储量的１９．１３％，将建成全国最大的磷化工基地。造成磷肥工业污染问题的原因一是矿物原料品位低，二是高污染的原料路线，三是非经济生产规模，四是落后的生产管理。要合理有效地利用资源，要使环境能够承载，就必须推行清洁生产，这是云南磷肥工业可持续发展的必由之路。     

Chemical characteristics of cloudwater over Maoer Mountain district

Samples of cloudwater, rainwater and ambient aerosol were collected over Maoer Mountain in the northeast of Guangxi Province in March 1988. The pH value of cloudwater ranged from 3.37 to 6.20 with a mean value of 4.34. SO42- , NO3- , NH4+, Ca2+ and H+ were the principal ionic species of cloudwater. The advance of cold fronts into Maoer Mountain appeared to lead to higher major ionic concentration and acidity than that of warm fronts. The relative acidity and concentration of NO3- of cloudwater were much greater than that of aerosol samples. With the exception of. NO3- and H+, most of the concentration of SO42- and NH4+ in cloudwater came from the nucleation scavenging of aerosol. Gaseous nitric acid and organic acid from local may be one of the important source of cloudwater acidity. Compared with other sites, Maoer Mountain can be as a clean contrast station for studying acidic precipitation in Guangdong and Guangxi provinces.     

试论景真糖厂实施清洁生产及建立循环发展体系

对勐海县景真糖厂原料基地和各生产工段的生产状况进行了综合评价分析,探明了该糖厂生产中产生的"三废"排放特征,存在问题以及环境经济状况,提出了建立循环发展体系,进一步提高环境经济效益的措施建议。     

石化行业的清洁生产

清洁生产是以提高企业的科学管理水平，降低原材料、能源资源的消耗，减少污染物的产生量和排放量，减少污染物的处理费用，实现最佳的生产工艺，最佳的资源配置、最佳的管理水平、最佳的污染控制设备为目标。文中根据石化行业生产工艺情况，说明石化行为实施清洁生产的方法和途径。     

煤炭非燃料利用与洁净煤技术

煤炭是中国的主要能源和资源，也是主要的污染源。煤炭燃料利用的不洁净使得其能源主导地位受到石油、天然气和新能源越来越大的挑战。寻求合理、高效、洁净的煤炭非燃料利用新途径应当成为煤化工发展的重要方向。本文在分析了煤炭燃料利用存在问题和前景的基础上，强调煤炭非燃料利用应当成为洁净煤技术的一种主要形式，并指出煤炭非燃料利用的合理途径。
