摘要：Water recharge is a key point to the construction of metro foundation pit, hence recharging water should be treated in order to make sure that the quality of water satisfies the need of protection of environment and recharging well. The aquifers in Nantong contain lots of ferrous ions and manganese ions, and are very heterogeneous in regions and layers. Shanghai Changkai Geotechnical Engineering Co.,Ltd studies about the water treatment and finds the appropriate filter materials, suitable thickness of these materials and size of sieve by the experiment in small water treatment installation. The result of experiment is applied in great water treatment installation and good results have been achieved.
