村镇污水的现状及一般处理方法研究

环保是全社会的事情,不仅城市要注重环保,村镇也要注重环保.但现今村镇环境令人担忧,绝大部分村镇不注重环保,居民没有环保意识,基本对污水不做任何净化,就直接就近排放到附近的河道或者沟渠,只有极少会做适当净化处理后,但也是直接排到附近的水环境或由地面渗入地下,对河水水质影响极大,使得村镇地区环境质量明显下降,不利于广大群众生存与生活,制约了村镇经济的健康发展.文中综述了村镇污水污染的现状及几种一般处理方法,并进行了比较分析.     

Aggregation and analysis of volatile organic compound emissions for regional modeling

A general two-step procedure for aggregating the hundreds of reported volatile organic compounds (VOCs) into a much smaller set of lumped classes appropriate for regional airshed modeling is described. In the first step, the compounds are condensed into a manageable number of emission categories which could be adapted to a variety of molecularly-based lumped chemical mechanisms. In the second step, the emissions are further aggregated into a smaller set of VOC classes which directly correspond to those in a particular model's mechanism. The application of this procedure is illustrated by aggregating the National Acid Precipitation Assessment Program (NAPAP) anthropogenic VOC emissions inventory the U.S. first into the 32-class system, and then into the groups of model species used in the latest version of the Regional Acid Deposition Model (RADM2.0). The importance of different VOC categories and source types on regional pollution production is explored by comparing the contributions of each of the emissions groupings, RADM model species, and major emissions sources, to total moles carbon VOC reacted in model simulations. For this particular anthropogenic inventory and chemical mechanism, it is found that over 50% of the moles carbon reacted is associated with mobile sources. Such analysis can help indicate which uncertainties in anthropogenic emissions inventories may have the greatest impact on results of regional simulations.

GIS and rural electricity planning in Uganda

Sustainable development is literally fuelled by the energy sector. In Uganda, the electricity sector has experienced dramatic market liberation in recent years. This reform was centred around the unbundling of the main government utility, Uganda Electricity Board (UEB), a monopoly divided into three companies created to introduce competition into the market. Market reform has also led to the creation of a regulatory body and a rural electrification fund with the aim of subsidising rural electricity investments. Through a multi-sectoral programme financed by the World Bank and the Global Environment Facility (GEF), the Ministry of Energy is developing a Rural Electrification Master Plan to provide a more systematic tool for rural electricity investments. Unlike previous approaches, this plan is demand driven. This paper discusses the use of Geographic Information Systems (GIS) in the planning process for rural electrification. The aim is to identify patterns of demand and priority areas for investment. By creating a demand-side scenario, electricity can then be supplied to targeted areas. A cross-sectoral view is taken to examine the energy demand patterns using physical data and available country statistics, incorporated into a GIS master database. Based on geo-referenced data of population and existing infrastructure, the initial priority demand-side sectors targeted are education and health. An energy benefit point system is then applied to each sector based on local conditions and needs assessments. Their aggregated points then provide an indicator of energy demand distribution for electricity planning at district level. As a result of this preliminary work, specific areas could then be targeted for investment and optimised supply systems could be designed, which include off-grid renewable energy plants such as small-scale hydropower schemes.     

氮化物在土层中的迁移与转化的研究

通过摸拟实验,研究了氮化物在土层中的迁移与转化作用。结果表明,土层对NH_4~+有很强的吸附作用,NH_4~+难以通过土层进入地下水中:NO_3~--N基本上不被土层吸附,能顺利通过土层进入地下水,故是地下水氮污染的主要形式。

Prenatally diagnosed portocaval shunt and postnatal outcome: a case report

Congenital absence of the portal vein (CAPV) is a rare anomaly in the form of a portocaval shunt, whereby the intestinal and splenic venous drainage bypasses the liver and drains directly into the systemic circulation. We report a case of CAPV diagnosed prenatally after the recognition of a dilated umbilical vein draining directly into a large inferior vena cava (IVC). The IVC then drained into the right atrium of a dilated, hyperdynamic heart. The ductus venosus could not be identified. Repeated postnatal scans showed a gradual disappearance of venous lakes in the region of the porta hepatis and a clear drainage of the splenic vein to the left renal vein and the superior mesenteric vein to the IVC. From birth up to twelve months follow-up there was no evidence of liver dysfunction, encephalopathy or liver lesions. Copyright © 2004 John Wiley & Sons, Ltd.     

生物脱硫机理及其研究进展

生物脱硫是８０年代发展起来的常规脱硫替代新工艺，通过微生物菌群的作用，可将硫化物转化成单质硫并回收，在生物脱硫过程中，氧化态的含硫污染物必须先经生物还原作用生成硫化物或Ｈ２Ｓ。然后再经生物氧化过程生成单质硫，才能去除。该文着重介绍了光合细菌和无色硫细菌的脱硫机理及其影响因素，光合细菌脱硫，由于条件苛刻，研究进展不大，仍处于分批试验或实验室小试阶段；无色硫细菌脱硫，近年来很活跃，并取得一些进展，已进     

渤海直排海污染源排放特征及管理对策研究

本文根据2011－2020年渤海直排海污染源监测数据,分析了渤海直排海污染源污染物排放特征及变化趋势,总结了2017年以来特别是渤海综合治理攻坚战实施后直排海污染源治理成效,并提出相应的管理对策。研究结果表明:2011－2020年,渤海直排海污染源污水排放量与黄海、东海和南海海区相比一直处于低位,化学需氧量、氨氮、总磷等污染物排放量总体呈先增加后减少的趋势;从2018年渤海综合治理攻坚战实施开始,直排海污染源入海污水总量呈明显上升趋势,但化学需氧量、总磷、总氮等主要污染物总量和浓度比明显下降,直排海污染源达标率呈逐年上升趋势;空间分布上,山东省、辽宁省属于直排海污染源排放量和排放强度高的省份;时间分布上,2018－2020年第四季度化学需氧量、总氮、总磷、氨氮等主要污染物排放量呈明显上升趋势。结合渤海直排海污染源排放特征,建议应健全渤海直排海污染源管控体系,分类推进渤海直排海污染源精准整治,提升渤海直排海污染源监测能力,为深入开展渤海直排海污染源污染治理提供支撑。
