铁炭微电解法预处理浆纱废水的研究

研究了采用铁炭微电解法预处理浆纱废水.试验结果表明,经微电解处理后的废水,COD的去除率达到67.2%,BOD5/COD从0.07提高到0.32,废水的可生化性得到显著提高.通过正交试验考察pH、反应时间及铁炭对比处理效果的影响,并对各因素作了单因素影响试验,确定了最佳工艺条件.

Application of the analytic hierarchy process to select characterization and risk-based decision-making and management methods for hazardous waste sites

Environmental managers at U.S. Department of Defense (DoD) installations overseas are faced with the challenge of managing contaminated sites at these installations with little information on the extent of contamination or the risk posed by the site. In this regard, DoD managers overseas encounter a situation quite similar to the situation faced by decision makers in the U.S. who are managing brownfields. Innovative site characterization and risk-based decision-making methods, which are currently being developed for expeditious application at brownfield sites in the U.S., may also be appropriate for application at overseas DoD sites. In this paper, the analytic hierarchy process (AHP) is used by DoD decision makers to evaluate and rank innovative site characterization technologies and risk-based decision-making and management methods, for use at installations in Korea. Results indicate that for sites with high potential risk the decision makers preferred site characterization technologies that produce data of high quality and a method that can be used to establish credible risk-based remediation goals. This study provides a framework for applying characterization technologies and risk management to poorly characterized contaminated sites in developing countries, where resources for remedial actions may be limited.
