A simplified suspended growth integrated system with an anaerobic zone in front of the aerobic one was used for the development of the bacterium Acinetobacter for phosphorus removal. The pilot plant experimental equipment was built at the Prague municipal works. The tests were carried out on a comparative basis, the control system was operated as a completely mixed activated sludge process. In the integrated system a to phosphate removal of 80 to 86% was achieved only in a biological way. In the control system, there was no development of Acinetobacter and the biological phosphate removal was only 5%. To rise it to the extent comparative with the integrated system, high doses of ferric chloride for a simultaneous precipitation of phosphate were required. The results obtained showed that the strictly biological process in the integrated system could meet normal practice requirements, even though it is not able to compete with the simultaneous phosphate precipitation using high coagulant dosages as for as the attainable efficiency and higher values of the sludge index are concerned. 相似文献

Passive structural control techniques are generally used as seismic rehabilitation and retrofit methodologies for existing structures. A poorly explored and exciting opportunity within structural seismic control research is represented by the possibility to design new structural forms and configurations, such as slender buildings, without compromising the structural performance through an integrated design approach. In this paper, with reference to viscous dampers, an integrated seismic design procedure of the elastic stiffness resources and viscoelastic properties of a dissipative bracing‐damper system is proposed and developed to ensure a seismic design performance, within the displacement‐based seismic design, explicitly taking into account the dynamic behaviour both of the structural and control systems. The optimal integrated seismic design is defined as the combination of the variables that minimizes a suitable index, representing an optimized objective function. Numerical examples of the proposed integrated cost‐effectiveness seismic design approach both on an equivalent SDOF system and a proportionally damped MDOF integrated system are developed defining the design variables, which minimize the cost index. Validation of the effectiveness of the proposed integrated design procedure is carried out by evaluating the average displacement of the time‐history responses to seven unscaled acceleration records selected according to EC8 provisions.

The U.S. Geological Survey numerical groundwater flow model, MODFLOW, was integrated with an agent-based land-use model to yield a simulator for environmental planning studies. Ultimately, this integrated simulator will be used as a means to organize information, illustrate potential system responses, and facilitate communication within a participatory modeling framework. Initial results show the potential system response to different zoning policy scenarios in terms of the spatial patterns of development, which is referred to as urban form, and consequent impacts on groundwater levels. These results illustrate how the integrated simulator is capable of representing the complexity of the system. From a groundwater modeling perspective, the most important aspect of the integration is that the simulator generates stresses on the groundwater system within the simulation in contrast to the traditional approach that requires the user to specify the stresses through time. 相似文献

作为当前高速铁路建造中出现的一种新型客站形式———房桥合一结构体系已经开始应用于实际工程,其抗震设防研究有着迫切需求和重要意义。基于此,本文对房桥合一结构中设置层间隔震来实现减震控制开展研究工作,并重点探讨此类控制方法的参数优化策略。首先建立了房桥合一结构数值模型,通过引入虚拟激励法推导了高效准确的随机计算式,继而指出采用参数域方法进行优化更为合理,它可实现隔震层参数有效配置。最后,通过数值研究对随机地震激励下房桥合一结构层间隔震优化策略进行了验证分析,分别基于单桥模型和多桥模型研究了其减震机理和减震效果,提出可提高减震效果的参数优化策略。本文研究结果表明:设置经过参数合理优化的层间隔震装置对房桥合一结构减震是可行且有效的。 相似文献
