锰砂除锰中试试验探讨

The discussion of demagnetization by Manganese sand in pilot plant

城市管网中会出现"黄水"主要是由于水中的微量铁锰离子被氧化随水流冲出造成。为控制出厂水中的锰,开展了锰砂除锰中试试验。锰砂对原水中不同浓度的锰去除效果均比较好,在对浊度去除和运行时间方面,锰砂运行效果逊于石英砂滤料。

＂Yellow＂ is mainly due to trace iron and manganese ions in water was oxidized with water out of city pipe network will cause. In order to control the manganese in the factory water,the test experiment of manganese sand except manganese is carried out. Manganese sand to different concentrations of manganese in the raw water to remove the effect of good, in the removal of turbidity and running time, manganese sand running less than quartz sand filter.
