这项工作的目的是确定是否可以通过用粉末活性炭或阴离子树脂修正的硅藻土（DE）预涂层过滤器来去除溶解的有机碳（DOC）。在第一系列实验中，评估了各种预涂层配置（DE尺寸、修正类型和浓度以及预涂层重量）对合成原水源中溶解有机物和浊度的初始去除率。在第二系列实验中，测试了各种身体饲料成分在保持或改善浊度和有机碳去除的能力，通过最佳预涂层实现，同时通过过滤器的水头损失保持在最小。在预涂层和身体饲料中使用强碱阴离子树脂对去滤池进行改进，可显著去除紫外线吸收率和DOC（>50%），并具有良好的浊度降低和可接受的水头损失。 包括22个参考文献、表格和图表。

The purpose of this work was to determine whether dissolved organic carbon (DOC) could be feasibly removed by diatomaceous earth (DE) precoat filters amended with powdered activated carbon or anionic resin. In the first series of experiments, various precoat configurations of DE size, amendment type and concentration, and precoat weight were evaluated for their initial removals of dissolved organic matter and turbidity from a synthetic raw water source. In the second series of experiments, various body feed compositions were tested for their ability to maintain or improve the turbidity and organic carbon removal achieved by the optimum precoat while head loss through the filter was kept to a minimum. Amending the DE filter with a strong-base anionic resin in the precoat and body feed achieved significant removals of UV absorbance and DOC (>50 percent) with excellent turbidity reduction and acceptable head loss development.
