Proceedings of the A and WMA's 97th Annual Conference and Exhibition;Sustainable Development: Gearing Up for the Challenge

作者： Heckel, Pamela F. Cincinnati Earth Systems Science Program Department of Civil and Environmental Engineering University of Cincinnati Cincinnati OH 45221-0071

Several international agreements developed during the past decade have emphasized the reduction of greenhouse gas emissions to delay or reverse the current global warming cycle. Carbon dioxide, as an abundant, global greenhouse gas, has been pegged as the chief villain in global warming. Much of the carbon sequestration research has focused on the largest plants, trees. The goal of this work is to reinforce the idea that planting trees in urban areas and along rural roads can make a measurable difference in air quality.

Biosurfactants produced by microbial activities may potentially promote efficiency of solid waste composting. A study was performed to characterize the effect of biosurfactant on solid waste biodegradation during a composting process. Solid waste was shredded then treated in a 8-L batch reactor. Biosurfactant production, characteristics and maturity degree were monitored every day throughout the process. Biosurfactant was examined on the basis of surface tension and emulsification capacity. The maturity degree was evaluated by measuring indices including C/N, CHA (Humic acid carbon) and CFA (fulvic acid carbon). With the experimental results, the impact of biosurfactant production on compost maturity was studied, which provided important implications in understanding mechanisms of solid waste composting. This research output was also proved to be valuable for improving the composting efficiency and providing technical support for waste management.

This paper describes methodological development of an intuitive river-pollution index (RPI) to allow assessment of priorities for water quality management in a river basin. The proposed RPI improves upon existing approaches as it is directly linked to water quality criteria and designated water uses, and reflects the importance of different water uses in a given reach. The RPI ranges from 1 (ideal water quality) to 5 (worst water quality) for various water-use categories. Through this technique, two types of RPIs can be generated for a river basin: (a) an RPI for each water-use category and (b) weighted RPI. Following the development of the technique, concepts of plan efficiency index (PEI) and benefit/cost (B/C) ratio are introduced to make comparisons of management plans more intuitive. Applicability of the developed RPI is illustrated by applying to a number of examples. Reasonable results have been obtained demonstrating that the proposed RPI is a useful tool for not only rating water quality but also ranking management plans.

Bioremediation is an emerging technology that helps clean up soil and groundwater, which are contaminated with petroleum products. This study investigates the bioremediation of petroleum-contaminated subsurface in a western Canadian context. Screening and enhancement of gasoline degradable local psychrophilic microorganism strains are conducted for the soil samples acquired from petroleum-contaminated sites and yard compost. Four purified strains obtained through the process are applied in batch experiments to determine their performance under various conditions. A factorial design is then conducted with four factors (nutrient richness, inoculation amount, temperature, clay/silt content) at two levels. The results show that clay/silt has the highest negative effect on degradability of the microorganism followed by temperature with positive effect. Validation of these results is being processed in a pilot-scale physical model and on a practical site with one- and six-month experimentation periods, respectively.

Integrated simulation-optimization approach for real-time dynamic modeling and process control of surfactant-enhanced remediation at petroleum-contaminated sites

引用

Practice Periodical of Hazardous, Toxic, and Radioactive Waste Management 2003年第2期7卷 95-105页

作者： Huang, Y.F. Li, J.B. Huang, G.H. Chakma, A. Qin, X.S. Environmental Systems Eng.Program Faculty of Engineering Univ. of Regina Regina Sask. S4S 0A2 Canada Dept. of Chemical Engineering Univ. of Waterloo Waterloo Ont. N2L 3G1 Canada

Surfactant-enhanced remediation is an effective approach for dealing with subsurface-contaminated sites. However, in studying and controlling the related processes, difficulties exist in incorporating a complicated numerical simulation model that is needed for process forecasting within a real-time nonlinear optimization framework that is critical for supporting process control. In this study, an integrated simulation-optimization approach was developed for supporting real-time dynamic modeling and process control of surfactant-enhanced remediation at petroleum-contaminated sites. Subsurface modeling is combined with a dual-response surface method to develop a system for generating optimum operation conditions under various site conditions, through the support of a nonlinear optimization model. The development methodology was applied to a real-world case study in western Canada. Using the developed three-dimensional multiphase and multicomponent model, the surfactant-enhanced remediation process that is being implemented on the study site was simulated. The results provide useful information for further dual-response surface analysis to support the development of an optimization model to determine optimum process operation conditions. Under each initial contaminant concentration, optimum operation conditions can then be identified through this combined dual-response surface method optimization approach. Thus, a decision support system can then be produced to guide decisions of remediation process control under various site conditions.

The domestic production of the most powerful ozone-depleting substances (ODSs) has permanently ceased and the abundant supplies of a number of refrigerants, fire-fighting agents, and solvents, once taken for granted, are now a thing of the past. The Navy has adopted a successful strategy for addressing the threat posed by the unavailability of ODSs. That strategy includes relying on a strategic reserve of ODSs. Considering that the strategic reserve will play a critical role in sustained Fleet operations into the middle of the century, it is important to record the history of the reserve and to document lessons learned in order to educate future generations that may face similar challenges. This is the third of three papers that cover all aspects of the Navy's strategic reserve of ODSs. Breslin (1999) documented the history of the Navy's effort to size, establish, and monitor a reserve designed to support Fleet operations until the middle of the century. Breslin, Smith, and Toms (2000) addressed in detail the process used to estimate the required size of the reserve, including the survey method, statistical analyses, and sizing algorithms. This paper discusses the Navy's plan for monitoring the Navy's strategic reserves of ODSs and describes the methods used in the monitoring process. In particular it discusses the underlying assumptions and statistical techniques associated with the Navy's prediction of the expected drawdown of the reserves. A comparison of actual data, collected since the strategic reserves began operations in 1995, with the predicted reserve drawdown, is included in the paper.

This paper reviews an inexpensive statistical-sampling methodology that can be used to determine the attrition rates of certain types of shipboard equipment. The methodology relies on surveys that are conducted in conjunction with regularly scheduled ship visits over a period of time and a statistical analysis of the survey results. The statistical technique allows for reasonably accurate estimates to be made of attrition rates. The specific example cited in this paper is related to galley-type refrigeration equipment, such as salad chillers, beverage dispensers, et cetera. In the case of galley-type refrigeration equipment, the Navy needs to know whether the Fleet's inventory of equipment relying on Class I Ozone-Depleting Substances (ODSs) will be replaced through natural attrition by the end of fiscal year (FY) 2005, at which time supplies of ODS-based refrigerants will no longer be available for use by ship galleys. This paper outlines the process used to gather data, the analysis of the data, and concludes that the Navy's inventory of galley equipment using Class I ODSs will be replaced through natural attrition by the end of FY05. The methodology reviewed by this paper has wider applications. For various types of shipboard equipment, the methodology can also be used to estimate with reasonable accuracy life expectancies, configurations, conditions, and other items of interest.
