In this study, it was investigated that the removal characteristics of tetrachloroethlene and herbicides using coalescing filtration.The results are obtained as follows :1.The adsorption isotherm of adsorbant treated with n-hexane is approximated by the Freundlich equation. However, the values, k and 1/n of the adsorbant are lower than those of activated carbon.2.After the column experiment using upward flow, it was confirmed that the formation of the coalescence of tetrachloroethylene was at the bottom of the column.3.The adsorption tests using poly propyrene polimer particles treated with n-hexane showed that water solubility of the herbicides is related to the efficiency of the removal rate. Humic acids were not adsorbed on this type of polimer particles.As described above, nonpolar micropollutants such as tetrachloroethylene and herbicides in the waste water are removed using coalescing filtration.

本文研究了聚结过滤对四氯乙烯和除草剂的去除特性，结果表明：1.吸附剂经正己烷处理后的吸附等温线符合Freundlich方程。但吸附剂的k值和1/n值均低于活性炭; 2.采用上向流柱实验，证实四氯乙烯在柱底形成聚结; 3.正己烷处理的聚丙烯高分子颗粒吸附实验表明，除草剂的水溶性与其去除效率有关。腐殖酸不吸附在这种聚合物颗粒上。如上所述，废水中的非极性微量污染物如四氯乙烯和除草剂使用聚结过滤去除。
