美国环保局提出了一项信息收集规则（ICR），作为reg neg过程的结果，该规则涉及开发这些信息的研究，以便在未来的规则制定中就技术实施和成本做出更明智的决定。这些研究必须由一部分公用事业公司通过评估GAC、膜或两者来进行。具体而言，服务于10万人以上且来源于地表水且进水总有机碳（TOC）浓度大于4.0 mg/L的系统，以及服务于5万人以上且来源于地下水且最终TOC大于2.0 mg/L的系统。 0 mg/L将受到这部分ICR的影响。快速小规模柱试验（RSSCT）是一种解决GAC性能问题的实验室规模方法。DBP前体去除研究的目标是生成具有代表性的工艺性能数据，用于在不同的有机DBP控制水平下估算处理成本。要研究的两种合适的候选技术是GAC吸附和膜分离工艺。这两种方法都被证明对去除DBP前体是有效的。处理研究可以通过实验室规模或中试规模的系统进行，使用已经存在的去除DBP前体的处理工艺产生的废水。 GAC研究中必须调查10分钟和20分钟的空床接触时间（EBCT）。对于实验室规模的GAC系统，必须在GAC研究中调查四次RSSCT运行。对于实验室规模的GAC系统，四次RSSCT运行必须捕捉季节变化。除TOC外，还应测量模拟分布式系统（SDS）条件下的紫外线吸收率（UV 254）以及THM、卤乙酸（HAA）和总有机卤化物（TOX）的形成。只有少数系统必须实施深度处理工艺，以满足拟议的第一阶段D/DBP规则要求，尽管EBCT为10分钟的GAC将被指定为最佳可用技术之一。 然而，在监管谈判期间，预计许多系统在满足潜在的第2阶段D/DBP规则要求方面会有更大的困难，因此可能需要实施先进的前体去除技术，如GAC或膜。为了按照第二阶段的要求评估低MCL对国家的潜在影响，有必要开发一个更强大的数据库，将深度治疗与DBP控制联系起来。本文的目的是:回顾RSSCT的设计和以前的使用，将其作为NOM和DBP形成的现场规模控制预测工具； 介绍一项新的RSSCT研究的结果；并从监管影响和成本方面评估结果。

The USEPA proposed an Information Collection Rule (ICR) as an outcome of the reg-neg process, which addresses studies to develop this information so that more informed decisions regarding technology implementation and cost can be generated in future rule making. These studies must be performed by a subset of utilities through evaluation of either GAC, membranes, or both. Specifically, systems that serve more than 100,000 people and whose source is a surface water with an influent total organic carbon (TOC) concentration greater than 4.0 mg/L, and systems that serve more than 50,000 people and whose source is a groundwater with finished TOC greater than 2.0 mg/L will be affected by this portion of the ICR. The rapid small scale column test (RSSCT) has been proposed as a bench scale method to address the performance of GAC. The objectives of the DBP precursor removal studies are to generate representative process performance data to be used for the development of treatment cost estimates at different levels of organic DBP control. The two appropriate candidate technologies to be investigated are GAC adsorption and membrane separation processes. Both processes have been shown to be effective for the removal of DBP precursors. The treatment studies can be conducted with bench scale or pilot scale systems using effluent from the treatment processes already in place that remove DBP precursors. Empty bed contact times (EBCT) of both 10 and 20 minutes must be investigated in the GAC studies. For bench scale GAC systems, four RSSCT runs must be investigated in the GAC studies. For bench scale GAC systems, four RSSCT runs must capture seasonal variability. In addition to TOC, UV absorbance (UV 254) and the formation of THM, haloacetic acids (HAA) and total organic halide (TOX) under simulated distributed system (SDS) conditions are to be measured. Only a few systems will have to implement advanced treatment processes to meet proposed Stage 1 D/DBP Rule requirements, although GAC with an EBCT of 10 minutes will be designated as one best available technology. However, during the regulatory negotiation it was anticipated that many systems will have more difficulty in meeting potential Stage 2 D/DBP Rule requirements and consequently may require implementation of advanced precursor removal techniques such as GAC or membranes. In order to evaluate the potential national impact of lower MCLs as required under Stage 2, it is necessary to develop a more robust database relating advanced treatment to DBP control. The objectives of this paper are to: review the design and previous use of the RSSCT as a predictive tool of field scale control of NOM and DBP formation; present results from a new RSSCT study; and evaluate the results in terms of regulatory implications and costs.
