Groundwater iron and manganese removal device

Abstract

The invention discloses an underground water iron and manganese removal device. The device comprises a first submerged pump, an aeration tank, a microorganism filtering device, a second submerged pump, a back flushing tank and a clean water tank, wherein the first submerged pump is arranged between the aeration tank and an underground well; the aeration tank and the microorganism filtering device are connected in sequence; an outlet three-way pipe is arranged at the lower end of the microorganism filtering device and is respectively connected with the back flushing tank and the clean water tank; the second submerged pump is arranged between the back flushing tank and the outlet three-way pipe; the microorganism filtering device comprises a top cover, a filtering column, a bottom cover and a transverse travel trolley; the top cover, the filtering column and the bottom cover are connected in sequence from the top down and are detachably connected with one another; the transverse travel trolley is used for supporting the filtering column. The device has the advantages that the filtering column part can be rapidly mounted and dismounted, so that wall scales inside the filtering column can be washed, the filtering space of the filtering column is guaranteed, and blocking of certain branch pipelines is avoided.

Description

technical field [0001] The invention relates to the field of water quality treatment, in particular to a device for removing iron and manganese from groundwater. Background technique [0002] In many areas of our country, the content of iron and manganese in groundwater is high, which exceeds or far exceeds the sanitary standards of drinking water and industrial water standards, which seriously affects its use value, so it must be removed. [0003] At present, the water quality treatment of groundwater mostly uses microorganisms to remove iron and manganese, but in the process of microbial iron and manganese removal, the divalent iron in groundwater is oxidized by chemical oxidation or iron-oxidizing bacteria into ferric oxide, which is attached to the filter material Or intercepted by the filter material; divalent manganese is oxidized by manganese oxidizing bacteria into manganese dioxide, which is attached to the filter material. Backwashing can wash away most of the iro...

AI Technical Summary

Problems solved by technology

Backwashing can wash away most of the iron oxides and manganese oxides from the filter material, but some of them will also adhere to the wall of the filter column to form wall scale, gradually reduce the filter space, and even block some branch pipes

However, most of the filter devices of the existing microbial iron and manganese removal devices are integrated structures, which is inconvenient to check the use of the intermediate filter column and replace the intermediate filter column; in addition, the filter devices of the existing microbial iron and manganese removal devices are mostly One-piece structure, it is inconvenient to check the use of the middle filter column and replace the middle filter column
