由于Ijsel湖水中的农药和微生物含量较高，荷兰Velserbroek的N.V.PWN北荷兰供水公司（PWN）被迫在两个地表水处理厂设置多重屏障。经过深入研究，这两个工厂都采用了基于超滤/反渗透（UF/RO）和紫外线照射/过氧化氢（UV/H2O2）的分离处理方法。本文介绍了两种装置的UF/RO和UV/H2O2研究的重点。包括表格、数字。

Due to high levels of pesticides and microorganisms in Lake IJssel water, the N.V. PWN Water Supply Company North Holland (PWN) of Velserbroek, The Netherlands, is forced to implement multiple barriers at two surface water treatment plants. After thorough research, a split treatment approach was adopted for both plants based on ultrafiltration/reverse osmosis (UF/RO) and ultraviolet irradiation/hydrogen peroxide (UV/H2O2). This paper presents the highlights of both the UF/RO and UV/H2O2 research for both plants. Includes tables, figures.
