Description
Technical field
The present invention relates to a kind of colliery high suspended matter sour water treatment and purification device purification method, belong to environmentally friendly technical field of water purification.
Background technology
China is with country that coal is main energy resource structure, influenceed by production practice and geological conditions, colliery will produce a large amount of black or yellowish-brown high-turbidity water in process of production, generally contain the suspensions such as a large amount of coal slimes, the index such as Fe, Mn, S is exceeded in various degree simultaneously, also there is fluoride or the situation of other heavy metals exceeding standards in indivedual Mine Systems, and moreover, considerable Mine System with sulfur-containing compound catalytic oxidation in coal seam due to forming H2SO4And making waste water in acidity, directly discharge will cause severe contamination to sewage to farmland and basin, while causing a large amount of wastes of water resource, it is necessary to processed to reach the requirement of reuse or discharge；For now, Mine waste water treatment is always a problem, and the existing most industrial sites in colliery are nervous, such as use relatively simple technique, for example " gravitational settling+lime is neutralized (or aeration up-flow neutralizes filter tank) ", though industrial sites area can be saved, is difficult to reach discharge standard；As used more perfect multilevel processing technology, though can reach discharge standard, because handling process is long, pond quantity is more, capacity is big, floor space is huge, infrastructure investment is high, often it is difficult to implement at the scene again, and because complex operation causes effluent quality unstable.
The content of the invention
（One）The technical problem to be solved
To solve the above problems, the present invention proposes a kind of colliery high suspended matter sour water treatment and purification device purification method, the technique such as neutralization reaction, flocculation reaction, tube settling, multi-medium filtering during traditional wastewater is processed organic assembling is an entirety, its small volume, system investments are few, floor space is small, simple to operate, high degree of automation, processing line is short out, processing cost is low, effluent characteristics are stable, and processing cost is low.
（Two）Technical scheme
Colliery high suspended matter sour water treatment and purification device purification method of the invention；Comprise the following steps：
The first step：Gravitational settling, water quality adjustment, after sewage enters preliminary sedimentation tank from mine, there is natural subsidence by Action of Gravity Field in bulky grain suspension, by suspended particle sedimentation separation bigger than water density in sewage, then sewage self-flowing enters regulating reservoir, is carrying out further sediment fraction suspension while water quality and quantity is adjusted；
Second step：Neutralization, flocculation Automatic Dosing, calculate nertralizer and flocculant dosage, by measuring pump, medicament is accurately added into system pipeline, nertralizer is added in sewer line flow, to realize quickly neutralizing the effect of sewage (regulation pH value to 6 ~ 9), before flocculant adds pipe-line mixer, sewage and liquid are mixed by (1 ~ 2 s) in moment by the helical structure of static pipeline mixer, mixed liquor carries out flocculation reaction by pipeline access arrangement；
3rd step：Flocculation reaction, by colloid electric double layer negatively charged in high valency electrolytes compression sewage, makes elimination of colloid stability；Polymer substance with the charges of different polarity and the strong suction-operated of colloidal particles, the not charged polymer substance even with colloidal particles same sex electric charge also has suction-operated with colloid, form the floccule body of colloid-macromolecule-colloid, floccule body is during settlement, net is caught, the particulate swept in sewage is rolled up, the effect of oil removal is effectively gone to reach；
4th step：Multi-medium filtering, multi-medium filtering area belongs to advanced treatment of wastewater category, it is mainly used in a small amount of flco of residual during removing prime is processed, the organic matter partly gone in water removal, bacterium even or even viral, for coal mine sewage, multi-medium filtering layer can form irony active filter film after activation, be capable of achieving the effective removal to Fe, Mn.
（Three）Beneficial effect
Compared with prior art, colliery high suspended matter sour water treatment and purification device purification method of the invention, the technique such as neutralization reaction, flocculation reaction, tube settling, multi-medium filtering during traditional wastewater is processed organic assembling is an entirety, its small volume, system investments are few, floor space is small, simple to operate, high degree of automation, processing line is short out, processing cost is low, effluent characteristics are stable, and processing cost is low.
Specific embodiment
A kind of colliery high suspended matter sour water treatment and purification device purification method, comprises the following steps：
The first step：Gravitational settling, water quality adjustment, after sewage enters preliminary sedimentation tank from mine, there is natural subsidence by Action of Gravity Field in bulky grain suspension, by suspended particle sedimentation separation bigger than water density in sewage, then sewage self-flowing enters regulating reservoir, is carrying out further sediment fraction suspension while water quality and quantity is adjusted；
Second step：Neutralization, flocculation Automatic Dosing, calculate nertralizer and flocculant dosage, by measuring pump, medicament is accurately added into system pipeline, nertralizer is added in sewer line flow, to realize quickly neutralizing the effect of sewage (regulation pH value to 6 ~ 9), before flocculant adds pipe-line mixer, sewage and liquid are mixed by (1 ~ 2 s) in moment by the helical structure of static pipeline mixer, mixed liquor carries out flocculation reaction by pipeline access arrangement；
3rd step：Flocculation reaction, by colloid electric double layer negatively charged in high valency electrolytes compression sewage, makes elimination of colloid stability；Polymer substance with the charges of different polarity and the strong suction-operated of colloidal particles, the not charged polymer substance even with colloidal particles same sex electric charge also has suction-operated with colloid, form the floccule body of colloid-macromolecule-colloid, floccule body is during settlement, net is caught, the particulate swept in sewage is rolled up, the effect of oil removal is effectively gone to reach；
4th step：Multi-medium filtering, multi-medium filtering area belongs to advanced treatment of wastewater category, it is mainly used in a small amount of flco of residual during removing prime is processed, the organic matter partly gone in water removal, bacterium even or even viral, for coal mine sewage, multi-medium filtering layer can form irony active filter film after activation, be capable of achieving the effective removal to Fe, Mn.
Embodiment described above is only that the preferred embodiment of the present invention is described, and not the spirit and scope of the present invention are defined.On the premise of design concept of the present invention is not departed from; the all variations and modifications that this area ordinary person makes to technical scheme; protection scope of the present invention all should be dropped into, claimed technology contents of the invention have all been recorded in detail in the claims.
