绿色创新及其激励机制

环境问题的最终解决需要绿色创新。绿色创新表现为一切关注环境－经济－社会协调发展，并使之得以实现的创新性活动。绿色创新的大量涌现需要从产权、市场、企业内部及政府政策等方面给予激励。     

Renaturing cities using a regionally-focused biodiversity-led multifunctional benefits approach to urban green infrastructure

If a ‘Renaturing of Cities’ strategy is to maximise the ecosystem service provision of urban green infrastructure (UGI), then detailed consideration of a habitat services, biodiversity-led approach and multifunctionality are necessary rather than relying on the assumed benefits of UGI per se. The paper presents preliminary data from three case studies, two in England and one in Germany, that explore how multifunctionality can be achieved, the stakeholders required, the usefulness of an experimental approach for demonstrating transformation, and how this can be fed back into policy. We argue that incorporating locally contextualised biodiversity-led UGI design into the planning and policy spheres contributes to the functioning and resilience of the city and provides the adaptability to respond to locally contextualised challenges, such as overheating, flooding, air pollution, health and wellbeing as well as biodiversity loss. Framing our research to encompass both the science of biodiversity-led UGI and co-developing methods for incorporating a strategic approach to implementation of biodiversity-led UGI by planners and developers addresses a gap in current knowledge and begins to address barriers to UGI implementation. By combining scientific with policy learning and defined urban environmental targets with community needs, our research to date has begun to demonstrate how nature-based solutions to building resilience and adaptive governance can be strategically incorporated within cities through UGI.

Uncovering results in electro-scrubbing process toward green methodology during environmental air pollutants removal

Present findings uncovered the electro-scrubbing process as a green methodology. This green methodology was assessed by an analysis of electrode dissolution into an electrolyte and acid fumes emission to the atmosphere. As an initial experiment oxidation effect of Co(II) by PbO₂ electrode revealed an enhanced oxidation efficiency of ∼20% compared to a Pt-coated Ti electrode. The mist concentration from the first scrubber test was approximately 30 times lower than that of the indoor air particles. In addition, molar mass of Co(II) and SEM analyses revealed no Co(II) or PbO₂ from the first scrubber. An analysis of the second scrubber showed no Co(II), PbO₂ or pH changes during a 24 h study confirming that no sulphuric acid escaped from the first scrubber or mediator containing electrolyte solution. This electro-scrubbing process was applied to the air pollutants removal process, in which a definite ratio between Co(III) and odor gases at given concentrations were identified. These results show that this electro-scrubber can maintain its initial concentration of Co(II) and H₂SO₄ by just adding water, and is become a highly sustainable and green methodology system without a loss of H₂SO₄ and Co catalysts to the environment.     

Experimental studies of removing typical VOCs by dielectric barrier discharge reactor of different sizes

This research conducted both lab-scale and pilot-scale tests by selecting toluene as the typical volatile organic compounds (VOCs) and by using the promising non-thermal plasma oxidation technology – dielectric barrier discharge (DBD). To develop baseline engineering data to demonstrate the feasibility of application of self-made DBD reactors, the peak voltage, gas flow speed, initial toluene concentration, discharge frequency and duty ratio were studied. The results showed that toluene removal efficiency improves with increase of electrical voltage, frequency and duty ratio, and declines with increase of polar distance, gas flow speed and toluene initial concentration. When the voltage increases, the energy efficiency rises first and then drops. The energy efficiency reaches the climax when the energy density reaches 150.8 J/L and 101.7 J/L in the lab-scale experiment and pilot-scale experiment respectively.     

一种以人为本的城市绿地评价方法及其应用——以南京市城市绿地质量评价为例

文章基于"以人为本"的理念,构建了从使用者角度对城市绿地质量评价的简明指标体系,采用多边形综合指标法及德尔菲法,兼顾科学性和可操作性,并应用该指标体系尝试分析南京市城市绿地质量。结果表明:南京城市绿地总体质量处于一般水平,其中公园绿地和风景名胜与自然保护区绿地质量较高。在各项评价指标中,南京居民对绿地管理质量满意度较低,视觉效果满意度、空间布局满意度较高。该评价体系从使用者角度展现了城市绿地的整体水平并直观反映出城市绿地所存在的问题,可为城市绿地规划与管理以及综合评价指标的构建提供重要的依据与参考。     

Bioaugmentation of DDT-contaminated soil by dissemination of the catabolic plasmid pDOD

A plasmid transfer-mediated bioaugmentation method for the enhancement of dichlorodiphenyltrichloroethane (DDT) degradation in soil was developed using the catabolic plasmid pDOD from Sphingobacterium sp. D-6. The pDOD plasmid could be transferred to soil bacteria, such as members of Cellulomonas, to form DDT degraders and thus accelerate DDT degradation. The transfer efficiency of pDOD was affected by the donor, temperature, moisture, and soil type. Approximately 50.7% of the DDT in the contaminated field was removed 210 days after the application of Escherichia coli TG I (pDOD-gfp). The results suggested that seeding pDOD into soil is an effective bioaugmentation method for enhancing the degradation of DDT.
