基于IPA分析的西安江村沟垃圾填埋场 景观生态修复策略

通过对西安江村沟垃圾填埋场内及周边村民生活生产区共57处土壤进行实测与问卷调查，运用IPA分析方法，从村民景观生态感知角度出发，探讨村民对周边垃圾填埋场实际景观生态感知与期望之间的关系，以及影响村民景观生态感知的重要因素，得出景观生态满意度模型。对影响景观生态感知因素的重要性与满意度进行测量，同时生成IPA表现值与期望值，并以此为依据结合土壤实验结论，运用景观生态恢复技术，对垃圾填埋场的景观生态恢复提出了相关设计策略。     

Managing solid waste in small hotels

Collectively, small hotels constitute a significant solid waste management (SWM) problem. Little research has focused on the SWM practices of small hotels. In the United Kingdom, much of the solid waste generated by small hotels goes to landfill. This study uses a constructionist approach to investigate SWM issues in small hotels in a local authority in Wales and examines the role of the public sector in helping small hotels manage their solid waste effectively. The results revealed that only a minority of small hotels were considering the adoption of sustainable SWM practices, either because hoteliers felt negatively about sustainable SWM alternatives or perceived challenges – an issue which necessitates government intervention. At the time of this study, the public sector provided only very modest services to enhance SWM practices. This study proposes a best practice model for the public sector to encourage small hotels to manage their solid waste effectively, in order to reduce or even eliminate waste for landfill. Local authorities' support is required to make waste management hierarchy options more accessible to small hotels and should incentivise better waste management through increasing the gap between the costs of landfill and recycling waste.     

填埋技术在工业废物处置场贮存作业中的应用

将填埋作业技术应用于工业渣场贮存作业,按照分区贮存、分期建设、分单元作业和临时覆盖等原则进行作业设计,可最大限度地减少工业废物处置场对地下水、地表水及大气的环境污染以及节省投资.     

渗滤液处理工程升级改造实例

以某地生活垃圾填埋场渗滤液处理工程升级改造为例,介绍了一种有效的渗滤液处理工艺.实践证明,采用“均质—MBR超滤—纳滤”工艺,并预留反渗透等深度处理工艺接口,是生活垃圾填埋场渗滤液处理工程升级改造的可行途径.     

垃圾渗滤液回用工程工艺设计

南方某城市垃圾填埋场为解决垃圾渗滤液污染环境和生产杂用水短缺问题,建设了垃圾渗滤液回用工程。该工程处理工艺采用物化 SBR 反渗透技术,出水水质达到了生产杂用的水质要求,取得了良好的社会效益和经济效益。介绍了工程的工艺流程、设计参数及设计特点。     

危险废物刚性填埋场设计造价初析

2019年9月30日,《危险废物填埋污染控制标准》(GB 18598—2019)颁布。新标准中明确提出了刚性填埋场的适用范围,补充了旧标准中对原柔性填埋场未能约定的固体废物的处置手段。文章以广东某拟建的刚性填埋场为案例,在其结构规划过程中对不同设计高度下的危险废物填埋场的主体结构造价成本进行了分析。通过对同条件下不同高度的刚性填埋单元进行结构建模,对主要建设成本横向比较,指出较佳的单元高度,为危险废物刚性填埋单元进行高度决策提供较优的参考选项和建议,从而实现危险废物刚性填埋场投资控制的更优化管理。     

城市垃圾填埋场生态修复综合施工技术

文章以重庆长生桥垃圾填埋场施工为实例,介绍了大体量、高水位、未完全降解、高浓度有毒有害气体溢出的城市垃圾填埋场生态修复综合施工技术,为大型运营状态下垃圾填埋场封场施工提供了关键技术支撑。该技术能够有效保障填埋场综合整治,最大限度满足场地后期开发利用,为改善城市生态环境,保证资源可持续利用,实现人与自然的和谐发展具有重要意义,为同类工程施工提供借鉴。     

昆明市生活垃圾处理与利用情况调查和评价

昆明市采用原生垃圾卫生填埋的单一方式处理垃圾,资源化程度低,同时对环境造成了严重的二次污染.昆明市生活垃圾处理应该采用基于垃圾分类(分选)的综合处理技术,即对于易降解的有机生活垃圾采用厌氧消化的处理方式,可以得到绿色能源和肥料;不易降解的部分进行回收或生产废弃物复合材料.卫生填埋只能作为垃圾产业化处理的最终处置方式.     

An Economic Analysis of the UK Landfill Permits Scheme

The UK will introduce in 2004 a system of tradable permits for the landfill of municipal waste, in response to an EU directive setting limits on such activity. Tradable permits are becoming an increasingly popular method of dealing with some environmental issues — for example, sulphur dioxide (SO2) emissions in the USA. This paper describes the background to the landfill proposals and provides an analysis of how the permit system might work. Estimates are made of the possible savings in compliance costs of a permit system compared with a conventional ‘command–and–control’ approach. These estimates are subject to a considerable degree of uncertainty, related to factors discussed in the paper.
