Embodiment Construction

[0020] The process of the present invention is as follows: after the mine water is premixed and flocculated and precipitated, it is put into the adjustment tank for preliminary hydrolysis and acidification, after the macromolecules of the organic matter are changed into small molecules, and then the solid suspension is separated through the mechanical grid pool, and then Enter the hydrolytic acidification tank, after hydrolytic acidification, contact oxidation under the action of aerobic organisms, degrade the organic matter in the sewage, and then precipitate the degraded water source, separate the aging biofilm shed by the aerobic organisms, and the clear water flows naturally Enter the reclaimed water pool, in the reclaimed water pool, the water source is filtered by quartz sand or activated carbon according to the nature of use, and the entire mine water treatment process is completed. Each process of the above treatment is in a separate pool, and each pool is independent o...

Abstract

The invention discloses a mine water treatment technique. The characteristic of the technique, which is different from other water source treatment techniques, is that a chemical method is first used for carrying out flocculation and sedimentation before biodegradation, and moreover, the flocculation-sedimentation technique is as follows: polyacrylamide accounting for 1 percent to 2 percent of the total weight of mine sewage is first added in a flocculation-sedimentation tank, solid suspending impurities, such as organic pollutant and pulverized coal ash, are sedimentated, aluminium polychlorid accounting for 10 percent to 15 percent is then added in the sediment, the aluminium polychlorid and the sediment are then mixed by a mixer, and react for 3 to 5 minutes, so that flocculent precipitate is formed, a filter press is used for separating out the flocculent precipitate, and after treatment, the obtained water is drained into a regulation tank. The invention has the advantage that the treatment technique integrated chemical flocculation with biodegradation can effectively purify mine sewage.

Description

technical field [0001] The invention relates to a mine water treatment process, in particular to a mine water treatment process, which is mainly to homogenize the water quality and quantity of the mine water, then brush off the fine suspended solids, enter the hydrolysis acidification tank, and carry out hydrolysis and acidification through the filler, then in the well Under the action of aerobic organisms, contact oxidation is carried out to degrade the organic matter in the sewage, and then the degraded water source is precipitated to separate the aging biofilm shed by the aerobic organisms, and the clear water naturally flows into the reclaimed water pool, in which the water source According to the nature of use, quartz sand filtration or activated carbon filtration is carried out to complete the mine water treatment process of the entire mine water treatment process. In order to realize this process, the present invention also provides a premixed flocculation sedimentation ...
