Mine water treatment technique

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 ...

Problems solved by technology

[0015] At present, there are many types of water purification equipment on the market, among which magnetized water purification equipment occupies a certain proportion, and biochemical treatment is also unique; among them, magnetized water purification equipment magnetizes water through high-frequency resonance, and then changes the structure of water molecules to achieve Anti-scaling and descaling features, this technology is only suitable for water purification of small boilers and other water inlet equipment; while biochemical treatment is suitable for various types of water purification, but a single biochemical treatment often cannot achieve the best effect. In the state of water purification, it is difficult to achieve the effect that the final water quality meets the quality of reclaimed water when treating sewage
