Abstract

The invention discloses a multichannel combined aeration tower which is particularly applicable to an underground water iron and manganese removal process and solves the problems of low oxygen dissolving efficiency, low effluent DO (dissolved oxygen) concentration, large occupied area and high energy consumption of an existing aeration device. The multichannel combined aeration tower comprises a water inlet pipe, a water distribution device, a tower body, a packing group, air pipes, blast aeration devices and a water outlet pipe, a water outlet of the water distribution device is formed in the top of the tower body, a water inlet of the water distribution device is connected with the water inlet pipe, the packing group is arranged inside the tower body, the blast aeration devices are symmetrically arranged on the lower portion of the tower body and connected onto the outer wall of the tower body through the air pipes, the water outlet pipe is arranged at the bottom center of the tower body, and the bottom of the tower body is inclined downwards from the periphery to the center. The multichannel combined aeration tower is used for secondary aeration in a secondary filtering oxidation process with iron and manganese coexistence.

Description

technical field [0001] The invention relates to an aeration tower, which is especially suitable for the process of removing iron and manganese from ground water. Background technique [0002] In many areas of our country, groundwater is used as the water source, and there are few groundwater pollutants, mainly iron and manganese exceeding the standard. Both iron and manganese are essential trace elements for the human body. Small amounts of iron and manganese are beneficial to the human body. Iron-deficient people will suffer from iron-deficiency anemia, anorexia and other diseases. Manganese deficiency will cause growth and reproductive disorders and central nervous system disorders. Wait. However, excessive iron and manganese will also bring a lot of inconvenience and harm to people's life and production. [0003] At present, the groundwater removal of iron and manganese in most areas of the country adopts the contact oxidation method, that is, first oxygenates the water...
