一、概述佳木斯市城市给水水源采用地下水。这些地下水中含有过量铁质。去除铁质的水处理工艺为曝气——天然锰砂过滤。过去,我们各净化站的曝气设备有重力式接触曝气架和空气压缩机两种。一九六九年初,我们成功地把水一气射流泵作为曝气设备应用于除铁工艺中。几年来,经过不断的实践和总
I. General description Ground water is used for water supply in Jiamusi City. These groundwaters contain excess iron. The water treatment process for removing iron is aeration - natural manganese sand filtration. In the past, the aeration equipment at our purification stations consisted of gravity contact aeration racks and air compressors. In early 1969, we successfully applied a water-jet pump as an aeration device to the iron removal process. In recent years, after continuous practice and total
