厌氧氨氧化颗粒污泥的快速培养与形成机理   总被引:2,自引:0,他引:2  
利用反硝化颗粒污泥掺杂少量厌氧氨氧化污泥启动厌氧氨氧化反应器,掺杂体积比为10:1,旨在快速启动厌氧氨氧化反应器并培养厌氧氨氧化颗粒污泥。结果表明,反应器连续运行60 d,成功培养出厌氧氨氧化颗粒污泥。反应器启动可分为细胞自溶期、活性提高期以及活性稳定期3阶段,细胞自溶期,颗粒污泥大量裂解,PN/PS由0.6升高到1.25,VSS/SS由0.45降低至0.38。活性提高期,PN/PS比值降低,VSS/SS比值回升。反应器进入活性稳定期,NH4-N、NO2-N、NO3-N 3种氮素转化比率维持在理论值1:1.32:0.26左右,PN/PS比值继续降低至0.6,VSS/SS比值回升至0.41。培养过程中污泥颜色由黑经棕逐渐变为红色,内部有大量类似于厌氧氨氧化菌的球型菌和椭球型菌。  相似文献

绿色絮凝剂PAS的性能及混凝机理探讨   总被引:2,自引:1,他引:1  
方月梅 《环境工程学报》2009,3(11):2021-2025
通过向聚硅酸中加入一种高价亲生物环保的金属离子Ti4+,制备了一种适合处理长江水的绿色絮凝剂PAS,并且通过实验确定了其处理长江水的最佳处理条件:酸性聚硅酸与Ti金属盐溶液复合,nTi/nSi=0.3;投加量为10 mg/L(以Ti4+计),pH=6~8,UV254的去除率>61.7%,浊度去除率>99%。PAS的混凝效果明显优于聚合铝和聚硅铝,而且矾花形成迅速,絮体密实、沉降快、出水更加清澈,无残留铝。Ti也是亲生物金属,健康环保。因此,PAS是绿色环保友好型絮凝剂,可作为饮用水专用絮凝剂。观察所形成絮体的形貌以及观测红外光谱图均发现,絮凝剂对胶体颗粒污染物有较好的架桥网捕与络合反应作用。  相似文献

As the digital economy develops rapidly and the network information technology advances, new development models represented by the network economy have emerged, which have a crucial impact on green economic growth. However, the relevant previous studies lacked the role of analyzing the direct and indirect effects of internet development on green economic growth at the prefecture-level city level. For this purpose, this paper aims to examine the intrinsic mechanism of the impact of internet development on green economic growth and provide empirical support for cities and regions in China to increase internet construction. Furthermore, the mixed model (EBM), which includes both radial and non-radial distance functions, is applied to calculate the green economic growth index. Fixed effect model and mediation effect model are also employed to test influence mechanisms of the internet development on green economic growth using panel data of 269 prefecture-level cities in China from 2004 to 2019. The statistical results reveal that internet development has contributed significantly to green economic growth. When the internet development level increases by 1 unit, the green economic growth level increases by an average of 5.0372 units. However, regional heterogeneity is evident between internet development and green economic growth, that is, the promoting effect of internet development on green economic growth is gradually enhanced from the eastern region to the western region. We also find that internet development guides industrial structure upgrading improves environmental quality and accelerates enterprise innovation, which indirectly contributes to green economic growth. And internet development mainly achieves green economic growth through enterprise innovation. Based on the above findings, we concluded that policymakers should not only strengthen the guiding role of social actors to promote the stable development of the internet industry, but also foster the construction of the three models of “internet+industry integration,” “internet+environmental governance,” and “internet+enterprise innovation” to promote green economic growth.

The flexible mechanism of the Kyoto Protocol, the clean development mechanism (CDM), should fulfil a twin objective: cost-effective greenhouse gas mitigation and enhancement of sustainable development in developing countries. As most host CDM countries have not established the proper institutional capacity to approve CDM projects and, at the same time, are prerogative to define sustainable development criteria for CDM projects, there is a clear need for a single set of guidelines or one evaluation system that accounts both climate and sustainable development considerations in the approval process of CDM projects. This paper proposes a set of sustainability criteria and indicators for CDM projects screening, reflecting the environmental, social, economic and technological dimension of sustainable development. Sufficient attention has been paid to determine globally relevant criteria and indicators. Priority has been given to energy sector CDM projects.  相似文献

Integrated rice–fish culture is a competitive alternative to rice monoculture for environmental sustainability and food productivity. Compared to rice monoculture, rearing fish in rice field ecosystems could increase food (rice and fish) production from this coculture. Moreover, the water productivity of rice–fish coculture is considerably higher than that of rice monoculture, because of double cropping. Despite these benefits, rice–fish coculture has not yet been broadly practiced. One of the potential challenges for the wider adoption of rice–fish coculture is water management. There are two forms of water involved in rice–fish cultivation: (1) blue water–surface and groundwater, and (2) green water–soil water from rainfall. The aim of this article is to focus on key factors determining the adoption of rice–fish cultivation through the effective utilization of blue–green water. We suggest that the efficient application of blue and green water in rice–fish coculture could help confronting water scarcity, reducing water footprint, and increasing water productivity.  相似文献

Finance plays a crucial role in a fast-growing economy that can lead to environmental degradation. The present study utilizes balanced panel data of 105 countries for the time span 1980–2016 to investigate empirical linkage among environmental degradations: economy and finance. It also unfolds the nonlinear impact of economy and finance on environmental degradation. Existing literature on environmental issues mainly focuses on individual case studies uncovering particular regions, but the comprehensive analysis is not available. To fill this gap, panels were classified into five divisions: global, regional, income-based, OECD-based, and carbon emission. The cross-sectional dependence test is applied to identify the degree of cross-sectional dependence among concerned 16 divisions. The second-generation panel models (CADF and Westerlund cointegration, DOLS, and DH heterogenous causality) are employed on a sample set to compute to unit root, cointegration, and long-run and short-run dynamics among concerned variables, respectively. The findings infer the inverted EKC and U-shaped EKC in 10 and 3 out of 16 divisions with respect to environmental degradation—economy nexus, respectively, while 8 and 2 out of 16 divisions indicate the inverted EKC and U-shaped EKC, respectively, in terms of environmental degradation—finance nexus. In 12 out of 16 divisions, the energy consumption uplifts the CO2 emissions. The DH causality affirmed a bidirectional causality among economy, finance, and energy consumption, respectively.
