一项研究评估了颗粒活性炭（GAC）吸附去除饮用水中痕量有机污染物和替代物的有效性和成本。还评估了废GAC多次再活化的效果。结果表明，当对总有机碳或总有机卤化物进行评估时，重新活化的GAC出水基本上等同于未活化的GAC出水。尽管观察到一些再活化副产物的水平较低，但最大相关风险水平仅为100000000分之三。设计和建造3-mgd GAC吸附和再活化设施需要约220万美元（1983年美元）的资本投资。对于20分钟的空床接触时间和三个月的重新激活周期，该设施的运行和维护成本预计约为0.14美元/1000加仑。包括6个参考文献、表格、图表。

A study evaluated the effectiveness and cost of removing trace organic contaminants and surrogates from drinking water by granular activated carbon (GAC) adsorption. The effect of multiple reactivations of spent GAC was also evaluated. Results indicated that reactivated GAC effluent was essentially equivalent to that of virgin GAC when total organic carbon or total organic halides were evaluated. Although low levels of some reactivation by-products were observed, the maximum associated risk level was only 3 in 1,000,000,000. A capital investment of approximately $2.2 million (in 1983 dollars) was required for design and construction of the 3-mgd GAC adsorption and reactivation facility. The operations and maintenance cost for this facility was projected to be approximately $0.14/1,000 gal for a 20-min empty bed contact time and a three-month reactivation cycle.
