Description

A kind of mine water treatment technique
Technical field:
The present invention relates to a kind of mine water treatment techniques, belong to field of waste water treatment.
Background technique:
China is maximum coal production state and country of consumption in the world, and in the world a few with coal for main energy One of the country in source, Coal mine excavation need to pour a large amount of water, as mine water into coal mine digging space, and mine water is Contaminated underground water in process of coal mining.According to statistics, the China's coal-mine ton coal displacement that is averaged is 2-2.5 tons, however China Coal field is often in water deficient regions, therefore is of great significance to treating mine drainage reuse.
For coal mine in recovery process, there are a large amount of mine waters to need to discharge, and the suspension content of mine water is significantly larger than Table water, sensory properties are poor；And the granularity of contained suspended matter is small, light specific gravity, sinking speed is slow, coagulation effect is poor；In mine water The total ion concentration contained is more much higher than general surface water, increases the difficulty of processing.If the untreated direct outlet of mine water, Not only environment is caused to influence, or to the significant wastage of water resource, faces the above problem, be adequately and reasonably industry using mine water The trend of interior environmental protection development.
Currently, the processing method for mine water is existing very much, including reverse osmosis, electrodialysis, ion exchange etc., but The water quality of guarantee production water that can not be stable belongs to dangerous waste moreover, obtaining mixed salt after treating mine drainage, still has danger to environment Evil.
Summary of the invention:
The purpose of the present invention is to provide a kind of mine water treatment techniques.
The present invention is implemented by following technical solution: a kind of mine water treatment technique comprising following process: process (1) is removed Silicon, process (2) are gone firmly, and process (3) removes SS, process (4) organic concentration, and process (5) divides salt to crystallize, in which:
The process (1) removes silicon: by mine water investment except pH=8-11 is adjusted in silicon pond, sequentially add magnesia mixture, PFS and PAM, removes total silicon in water removal, and control desiliconization produces total silicon≤50mg/L of water；
The process (2) is gone firmly: desiliconization produces water and initially enters a heavy pond, successively adds Ca (OH)2, PFS and PAM, removal Mg in water2+, water production control pH=11-12, production water Mg2+≤10mg/L；Then enter secondary settling tank, adds Na2CO3, PFS and PAM, control go to produce water Ca firmly2+≤10mg/L；
The process (3) removes SS: it is described to go after producing water adjusting pH=6-8 firmly, the production of SS≤1mg/L is obtained after filtering Water；
The organic concentration of the process (4): the production water of the process (3) enters in organic film condensing device, controls influent pressure Power is 3-5MPa, and the concentration for obtaining concentration concentrated water and COD≤100mg/L produces water；
The process (5) divides salt to crystallize: the concentration production water enters nano filter membrance device and carries out a point salt treatment, controls influent pressure Power is 3-5MPa, obtains nanofiltration and produces water and nanofiltration concentrated water；The nanofiltration produces water and is sent into evaporative crystallization in crystallizing evaporator, obtains chlorine Change sodium and sodium chloride distilled water；The nanofiltration concentrated water is sent into evaporative crystallization in crystallizing evaporator, obtains sodium sulphate, sodium sulphate distillation Water and crystalline mother solution, sodium chloride distilled water and sodium sulphate distilled water as it is final produce water can reuse, such as support shrimp.
Further, it is gone in hard in the process (2), it is described to go to produce that water passes sequentially through active carbon filter and ultrafiltration fills firmly Set double-filtration processing.
Further, in described (4) organic concentration, the concentration concentrated water enters in the pond A/O, by the organic place of activated sludge After reason, organic concentration obtains the production water of COD≤100mg/L.
Further, the process (5) is divided in salt crystallization, and the crystalline mother solution returns in the process (4), is carried out again Organic concentration operation.
Advantages of the present invention: the present invention pass sequentially through except silicon, go it is hard, go SS, organic concentration and salt divided to crystallize, having obtained can The distilled water of reuse, an and point salt treatment is realized to mine water, and can stably obtain high quality sodium chloride crystal salt and Sulfate crystal salt avoids in conventional processes silicon, magnesium, calcium, SS or organic matter in crystal salt and not can avoid to be entered Problem solves the problems, such as that high quality salt can not be stably obtained in conventional processes.
By being arranged in organic concentration and before dividing salt to crystallize the two film process except silicon, going firmly and go SS's in this programme Process ensure that stablizing for film process carries out, avoid the problem of technique can not carry out caused by blocking up because of film dirt, and sodium chloride Distilled water and sodium sulphate distilled water as it is final produce water can reuse, such as support shrimp.
