干旱地区水污染控制系统初探

应用数学规划方法,科学地组织污染物的排放或科学地协调各个治理环节,以乌鲁木齐市水磨河流域水污染控制系统为例,对干旱地区水污染控制系统进行了初步探索,从而得出干旱地区污水处理费用的合理负担,并得出污染物排放的数量,质量受自然地理条件制约的结论。     

浅谈环境监测社会化的质量监管新思路

分析了现阶段社会环境检测市场的发展现状及存在的问题,探讨了从环境检测上岗能力、专业技能再教育、从业履历和信用等方面对社会环境检测从业人员进行管理的必要性,提出在机构环境监测能力、检测人员结构流动性、仪器设备在用状态和更新频率、从事环境监测业务信用等方面建立评估机制,推动环境监测市场健康发展。     

石化行业给排水系统设计图纸环境监理审查要点

石化行业废水种类多样、毒性较大,给排水系统的设计会直接影响石化项目建成后周边地表及地下水环境质量。设计文件的环保审查是环境监理的重要依据之一,其中,相关的设计图纸对下一步建设工作具有指导作用,是所有施工单位的施工依据。以某石化行业为例,对给排水系统设计文件的收集进行了分析,并根据设计图纸环保审查中存在的问题,对环境监理如何提高在设计会审中的作用,设计阶段如何对设计图纸进行审查以及审查的重点内容等进行了阐述。     

环境监理运行模式初探

围绕环境监理的基本职责 ,对捆绑式、专一式、切块式 3种不同的环境监理运行模式进行了探讨。提出切块式环境监理运行模式比较适合现阶段环境监理工作 ,是一种值得推广的环境监理运行模式。     

运用法律手段加强环境治理工作的有效性

单靠道德自律及经济、行政性处罚等手段 不可能从根本上解决环境问题,唯有加强法律作为硬性强制性手段,才能加大环保工作的有效性。     

烟尘烟气监测全程序质量监督评价方法研究

建立了烟尘、烟气监测全程序质量监督体系,确定了监督检查工作需要控制的环节,并细化了各环节需要重点关注的内容。以层次分析法等关键技术为基础,通过赋予监测全过程各环节不同的指标权重,建立了统一化、标准化的综合评价模式。研究将评价体系分为2个层次,一级指标3个,二级指标19个,并确定了每个指标的测评内容及计算方法。将该体系应用于6家监测机构的质量监督工作,证明其实用性和适用性良好。     

新形势下对环境统计工作的思考

分析了环境统计工作的定位和内容,以及第二次全国污染源普查、排污许可证与排污税制度、环境质量考核制度给环境统计工作带来的改革契机。针对固定源、城镇生活源与农业面源、移动源,提出了统计调查工作的设想。建议改变环境统计调查焦点,实现污染源统计空间格局"一张图";开拓环境统计分析品牌,推动环境统计方法研究;以政策管理需求为导向,完成环境统计工作体系的重构。     

污水处理厂投资全过程成本控制

本文综合论述了在水业市场化条件下，水务投资公司进行污水处理厂投资、建设和运营时，在投资决策前期阶段、设计阶段、建设阶段以及运营阶段等各水务价值链重要环节的成本控制方法，为水务投资公司在污水厂投资全过程的成本控制提供了参考。     

Use of an Action‐Selection Framework for Human‐Carnivore Conflict in the Bangladesh Sundarbans

Abstract: Human–carnivore conflict is manifested in the death of humans, livestock, and carnivores. The resulting negative local attitudes and retribution killings imperil the future of many endangered carnivores. We tailored existing management tools to create a framework to facilitate the selection of actions to alleviate human–carnivore conflict and applied the framework to the human–tiger conflict in the Bangladesh Sundarbans. We identified potential actions that consider previous management efforts, local knowledge, cost‐effectiveness, fieldwork experience of authors and project staff, previous research on tiger ecology by the authors, and recommendations from human–carnivore conflict studies in other countries. Our framework includes creation of a profile to improve understanding of the nature of the conflict and its underlying causality. Identified actions include deterrents, education, direct tiger management, and response teams. We ranked actions by their potential to reduce conflict and the monetary cost of their implementation. We ranked tiger‐response teams and monitoring problem tigers as the two best actions because both had relatively high impact and cost‐effectiveness. We believe this framework could be used under a wide range of human–wildlife conflict situations because it provides a structured approach to selection of mitigating actions.     

Domestic water conservation potential in Saudi Arabia

Domestic water conservation in arid climates can result in efficient utilization of existing water supplies. The impacts of conservation measures such as the installation of water-saving devices, water metering and pricing schemes, water rationing and public awareness programs, strict plumbing codes, penalties for wasting water, programs designed to reduce leakage from public water lines and within the home, water-efficient landscaping, economic and ethical incentives are addressed in detail. Cost savings in arid climates, with particular reference to Saudi Arabia, in relation to some conservation techniques, are presented. Water conservation technology and tentative demonstration and implementation of water conservation programs are discussed.
