Embodiment Construction

[0028] Such as figure 1As shown, the treatment system for removing manganese in metallurgical industrial wastewater includes 1-collection well, 2-coarse grid, 3-primary sedimentation tank, 4-pH value adjustment tank, 5-modified fly ash vibration adsorption Manganese removal device, 6-aeration tank, 7-biological oxidation filter, 8-secondary sedimentation tank, 9-clean water collection well; wherein, the metallurgical industrial wastewater containing manganese ions enters the collection well 1 through the waste water pipeline, where Centralized collection and preliminary stable adjustment are carried out. The outlet of the collection well 1 is connected to the coarse grid 2 through the wastewater pipeline, where large-diameter solid matter in the wastewater is removed. The outlet of the coarse grid 2 is connected to the primary sedimentation tank 3 through the wastewater pipeline. To further remove the insoluble substances in the wastewater, the outlet of the primary sedimentat...

Abstract

The invention discloses a treatment system for removing manganese from metallurgical industry wastewater. The system comprises a water collecting well, a coarse screen, a primary precipitation tank, a pH adjusting tank, a modified fly ash shaking adsorption manganese removal device, an aeration tank, a biological oxidation filter tank, a secondary precipitation tank and a purified water collecting well. The system creatively utilizes the ion chemical bonding characteristic of artificially modified fly ash, and specially processed fly ash and manganese metal ions in a normal-temperature aqueous solution undergo an ion chemical bonding reaction to make the manganese ions be adsorbed on the surfaces of modified fly ash particles, so adsorption purification of the manganese metal ions in wastewater is realized. The system using an advanced microwave technology, and modifies the fly ash through using microwave radiation with specific frequency, so the volume expansion of the fly ash particles is effectively promoted, and the adsorption capacity of the fly ash is greatly improved. The system realizes secondary use of thermal power plant and coal fired boiler wastes fly ash, and has very high environment benefits.

Description

technical field [0001] The invention relates to a treatment system for removing manganese in metallurgical industrial wastewater, which belongs to the field of wastewater treatment in environmental protection. Background technique [0002] Manganese is one of the elements widely distributed in the earth's crust. Its content in the earth's crust is 0.085%, accounting for about three ten thousandths of the total number of atoms in the earth's crust. Although there is very little manganese in seawater, the silt in the depths of the ocean contains three thousandths of manganese. Manganese dioxide is the most important among the oxides of various valence states of manganese. In nature, there is a large amount of natural manganese dioxide - pyrolusite, which is the main raw material for smelting ferromanganese alloys. When making glass, add a small amount of manganese dioxide as a decolorizer. Manganese dioxide can also be used as a combustion aid in the match industry, an oxidiz...
