常低温下EGSB处理生活污水的影响因素研究 总被引:2,自引:0,他引:2
在15~26℃的常低温条件下,采用EGSB处理生活污水,考察了进水流量、回流比、液体上升流速(Vup)、温度等因素对运行效果的影响。结果表明,当温度为26℃左右时,对于9~11 L/h的低进水流量,宜采用高回流比(1.6~2.5),对COD的去除率最高可达90%;对于15~24L/h的高进水流量,宜采用低回流比(0~0.6),对COD的去除率最高可达84%;当进水流量提高至30 L/h时,不宜回流,对COD的去除率降至77%;当进水流量分别为9、11、15、24、30 L/h时,最佳Vup分别为4.0、(3.1~3.6)、(2.7~3.4)、3.0和3.8 m/h,此时对COD的去除率分别高达90%、(87%~89%)、(83%~84%)、83%和77%;在无回流的条件下,适宜的进水流量为15~24 L/h,相应的HRT为0.5~0.8 h。当温度为15~26℃时,EGSB适宜的运行条件是高进水流量(15~24L/h)、高Vup(3.0 m/h)和低回流比(0~0.6),此时对COD的去除率高达81.9%以上。 相似文献

In recent years, researchers have paid increasing attention to the provision of access to clean and sufficient drinking water, sanitation facilities, and proper waste management in developing countries. This paper examines household access to these services in urban areas of Nepal by studying the comprehensive data of the Nepal Living Standard Survey (NLSS) for the 1995-1996, 2003–2004, and 2010–2011 periods. Multinomial logit models are employed to identify and analyse potentially influential factors. We find that education levels, household wealth, and distance to markets are among the significant determinants of household access to safe and secure drinking water, flush toilets connected to septic tanks, and proper liquid and solid waste disposal. Households located in relatively developed regions, such as the Midwest and Far West, tend to have better access to these services compared to households located in the ecologically sensitive mountainous regions. Education and employment opportunities are also relevant to service access in urban areas of Nepal. Stakeholder involvement and effective governmental intervention are also necessary. 相似文献

Adsorption, desorption and chemisorption are known to impact the dispersal of volatile organic and chemically reactive compounds in buildings. These same three processes may be used to advantage to control the levels of these compounds indoors using building sorption filtration devices. To add to the understanding of these processes, to provide the means to predict the impact of these processes on human exposure and to provide the tools needed to design gaseous filtration systems to mitigate the exposure to these compounds, a general approach to modeling the dynamics of these processes is presented. Equations are presented to account for the elemental advection, diffusion, sorption, and chemical transport steps affecting single component sorption dynamics in rooms and sorption filtration systems. These element equations are based on general principles and formulated in terms of fundamental physical parameters that may be determined using standard procedures. Models to predict room and sorption filtration system dynamics are formulated using assemblages of these element equations and a series of simplified models of these systems are derived. Initial applications to model single-component sorption transport in rooms and sorption filtration systems indicate that the approach has the potential to provide accurate predictions providing the sorption and chemical characteristics of the sorbate-sorbent system being considered are well-characterized. This potential is, however, compromised by the lack (or present uncertainty) of fundamental data relating to sorption equilibrium, porous diffusion, surface chemistry, and boundary layer mass transport 相似文献

Living in the suburbs is founded on mobility, as residents move to the periphery of the city, commute to work and travel for shops, schools and leisure. While there have been numerous studies raising critical questions on the vulnerability of outer suburban residents to loneliness, financial and mortgage stress, the actual experiences and challenges posed by the dependence of suburban life on mobility is rarely singled out for attention. Through purposive sampling and then snowballing, eight outer suburban residents participated in photo-elicited interviewing to detail their lifeworlds and mobility experiences. Problems ranged from getting to work to accessing schools, shops and even neighbourhood services as the suburban car culture was embraced but also constrained patterns of movement. However, there was also an array of positive experiences and alternatives to these patterns, including the pleasures to be found in traffic jams and the suburban environment and local actions to establish new pathways and means of movement as well as set up local employment options. Mobility constraint thereby generated a range of unexpected strategies, as residents exercised their agency to shape their experiences, create alternatives and to build suburban centred lives. 相似文献

ABSTRACTThe articles in this special issue demonstrate how objects can be interpreted as agents, as gendered images that make a statement, and how their impacts can be understood and assessed by human actors. They are differentially placed in matrices of power, and they can be manipulated to shift genders, to play with gendered combinations, to expand the limits of a particular gendered domain, to creatively play with reproductive imagery, and even to sell commodities in new and enticing ways in the mass media. Gendered religious objects are “statements” addressed not only to the eye but to the emotions, and part of a complex cultural field in which things can play important roles in people's lives. The links that connect ritual power to other forms of agency and biographical significance are perhaps the most significant links that we need to examine to understand them better in a world of many diverse cultural forms. 相似文献
