Abstract
The invention discloses an ecological northern alkaline mine water treatment system and an ecological northern alkaline mine water treatment method. Firstly, alkaline mine water passes through a primary sedimentation basin, so that large-grain suspended matters in the sewage are sedimentated, the sewage enters a primary filtering basin and is filtered after primary sedimentation, the primary filtering basin is mainly built with mixed Liyang soil and coal gangue, which are used as adsorbent for removing pollutants in the sewage, and in order to enhance the water treatment effect, the filtering basin consists of a plurality of alternate filtering basins and sedimentation basins; the sewage enters a sedimentation basin after primary filtration, aquatic weeds in the sedimentation basin are utilized to separate sludge from water and concentrate the sludge, pollutants in the sewage are further sedimentated, the sewage enters a secondary filtering basin and is filtered after sedimentation, the filtering basin is built with peat granules, and can effectively remove pollutants in the mine water containing waste machine oil, emulsified oil and other organic pollutants, and the salt balance and pH value of the water are regulated; finally, the filtered water flows into an ecological pool, and is used for raising ornamental fishes, and thereby the sewage is recycled.
Description
Technical field
The invention belongs to northern alkaline pit water processing technology field, relate in particular to alkaline pit water ecological treatment system in a kind of north and method.
Background technology
Coal mine water is meant that in the coal mining process all infiltrate down-hole mining spatial water, and the discharging of pit water is that colliery industry has one of source of pollution of industry characteristic, has a large capacity and a wide range.When pit water is flowed through coal-face and tunnel, influence because of receiving human activity, the coal petrography powder gets in the water with some organism; Generally contain in China's pit water with the coal petrography powder is master's suspended substance; And soluble inorganic salts, organic pollutant is less, does not generally contain Toxic matter.Therefore, pit water is carried out the purifying treatment utilization, with producing huge economic benefit and social benefit.
It is Coagulation Method that existing pit water is handled method commonly used, and dosing is big and mud that form is more hard to manage, is prone to form secondary pollution like miscarriage; Reverse osmosis method is handled and the running cost height; The simple filtering method of pit water treatment station; Adopt sand filtration or charcoal filter (gac or hard charcoal are filtrate); Except that the suspended substance in the water is had a spot of removal; Most of salinity is not almost had removal, and the pit water after handling still is alkalescence, can't satisfies the requirement of filtering boiler water coolant and landscape water.
At present, various types of pit water is handled and is all had such-and-such problem, is necessary various types of pit water is carried out deep research, inquires into corresponding New Method for Processing, improves the recycling rate of pit water, solves " bottleneck " problem of restriction coal mining enterprise development.
Summary of the invention
Problem to present existence; This programme has been invented alkaline pit water ecological treatment system in a kind of north and method; This method relates to the ecological pit water purification system of a kind of northern low temp area, is composed in series by preliminary sedimentation tank (dividing plate)-filtering basin (coal gangue of modification)-settling tank-filtering basin (peat particle)-ecological pool (aquarium fish).The flexible baffle that the preliminary sedimentation tank setting is from bottom to top interlaced, filtering basin are made up of modified gangue, and these filtering basin alternately are made up of some filtering basin, settling tank.The peat filtering basin are by the peat granulometric composition, and this system takes underground open tunnel type, but winter coating film, play antifreeze function.
This method makes full use of mine waste and raw material, has the treatment process that integrates pit water stage treatment-view, and filtering basin are main raw material with mine modified gangue and gac, and whole device flows automatically along massif.
The embodiment of the invention is achieved in that the alkaline pit water ecological treatment system in a kind of north, and this system comprises:
Preliminary sedimentation tank is used for precipitating the suspended substance of pit water, is provided with by from bottom to top interlaced flexible baffle, and block board thickness is too not thick, and the deposition certain thickness can come off voluntarily;
The one-level filtering basin are removed pollutent with modified gangue as water treatment absorbent, and these filtering basin alternately are made up of some filtering basin settling tanks;
Settling tank carries out mud-water separation and mud and concentrates, and the water outlet overflow after the clarification effluxes;
The pollutent in the pit water that contains used oil, emulsification wet goods organic pollutant by the peat granulometric composition, can be removed effectively in the cascade filtration pond, and regulates the pH value of pit water;
Ecological pool is used for pit water is carried out eco-filtration, the processing of waterplant digestion even depth, and the inside aquarium fish is main with carp.
Further, modified gangue is to be mixed by Li Yang soil and coal gangue.
Further, the peat particle is that peat+chestnut soil calcic horizon soil mixes.
Another purpose of the embodiment of the invention is to provide a kind of north alkaline pit water ecological treatment method, it is characterized in that this treatment process comprises:
The alkalescence pit water precipitates the macrobead suspended substance in the sewage through primary clarifier, gets into the one-level filtering basin through elementary oettIed sewage and filters;
Sewage behind primary filter gets into settling tank; Utilize the pasture and water in the settling tank; Carry out mud-water separation and mud and concentrate, further precipitate pollutants in sewage, get into the cascade filtration pond through oettIed sewage and filter; Removal contains the pollutent in the pit water of used oil, emulsification wet goods organic pollutant, regulates salt balance and pH value in the water;
Water after final the filtration flows in the ecological pool, is used to raise aquarium fish, reaches the cycling and reutilization of sewage.
Further, the one-level filtering basin mainly contain Li Yang soil and coal gangue mixes, and are used for the pollution that sorbent material is removed sewage, and in order to improve the water treatment effect, these these filtering basin alternately are made up of some filtering basin settling tanks.
Further, pasture and water are the seed of jog's tears or Caulis Miscanthis floriduli.
The present invention is a main raw material with the waste that the local mine of coal field produces, and has raw material and is prone to obtain, and have the effect that turns waste into wealth; This ecologic assemblage device is taked underground film covering method, but feedwater part round-robin method is taked in four seasons operation simultaneously, keeps water temperature; Pit water after the apparatus processes less than 7, can satisfy the requirement of boiler water coolant and northern landscape water near neutrality and pH; Pit water is carried out stage treatment, and the sludge quantity of generation is few, invests for a short time, effective, and running cost is low, has remarkable economic efficiency and ecological benefits.
