一、概述我国含铁含锰地下水为数不少。国内已开发的含铁含锰地下水水源,主要集中在东北、两广地区及长江中游一带。福建、江西、四川等部分地区,也都有这种地下水水源在使用。国内处理效果较好的几个除铁除锰装置如表1所示。由表1可见,当原水[Fe_4]<5毫克/升, I. Overview China has a large number of iron-bearing manganese-bearing groundwater. The domestically-developed iron-bearing and manganese-containing groundwater sources are mainly concentrated in the northeast, the Guangdong-Guangzhou area, and the middle reaches of the Yangtze River. Some parts of Fujian, Jiangxi, and Sichuan also have such groundwater sources in use. A few domestic iron removal and manganese removal equipments with good treatment effect are shown in Table 1. As can be seen from Table 1, when the raw water [Fe_4] is less than 5 mg/l,
