Abstract

The invention discloses complete equipment for removing iron ions and manganese ions from pit water and a removal method thereof. The equipment is composed of a cold water tank, a first water delivering device, a first stirring and water-distributing device, a second water delivering device, a second stirring and water-distributing device, a third water delivering device, a cation column, an anion column, a floating foam scraping plate device, a heating tank, a socket, a water discharge pipe, a hot water tank, a floating foam discharge pipe, a support, and a control system. Pit water sequentially enters the cation column through the first water delivering device, the anion column through the second water delivering device, and the heating tank through the third water delivering device. The hot water, which has been heated by the heating tank in the heating tank, is discharged into the hot water tank through the water discharge pipe. The floating foam in the heating tank is discharged out of the heating tank through the floating foam discharge pipe by the floating foam scraping plate device. The provided complete equipment and removal method thereof have the advantages of novel and reasonable structure, high impurity removing rate, and wide application range.

Description

technical field [0001] The invention belongs to the field of mine water purification devices and purification methods, and in particular relates to a complete set of equipment for removing iron and manganese ions in mine water and a removal method thereof. Background technique [0002] In many areas of my country, mine water sources, especially in major cities and regions in Northeast China, South China, Central South and Southwest China, have excessive iron and manganese. and industrial production are adversely affected. As early as the early days of the founding of the People's Republic of China, "groundwater iron and manganese removal" was established in my country. Its theory and application have experienced three development stages: natural oxidation method, contact oxidation method and biological method. But so far, how to realize the rapid and efficient removal of iron and manganese is still one of the common problems faced and need to be solved by the conventional wa...
