Abstract
This invention discloses a method for treating mine wastewater by membrane technology. The method comprises passing mine wastewater sequentially through a water storage tank, a water output pump, a mechanical filter (for removing large particles and some organic matters), a fiber ball filter (for removing floating oils, some colloids and organic matters), an activated carbon filter (for removing organic matters, chrome and residual chlorine), a fine filter (for removing impurities larger than 0.005 mm), and a reverse osmosis membrane unit (for capturing and removing heavy metals such as cadmium, zinc, molybdenum, copper, etc.) to obtain clean water with high quality for industrial and domestic use. Besides, heavy metals can be recovered from concentrated water. The method has such advantages as high efficiency, low cost, no secondary pollution, and high water resource conservation, and is environmentally friendly.
Description
Technical field
What the present invention relates to is a kind of processing method of handling mine wastewater, specifically a kind of processing method of methd for treating mine wastewater by using membrane technology.
Background technology
Metal mine, particularly sulfide metal mine all can produce acid waste water during ore dressing.Contain metal ions such as copper, zinc, molybdenum in these waste water, and the suspension content height, free settling does not present finely divided glue; Characteristics are that quantity discharged is big, and direct contaminate environment is being destroyed the water resources of growing tension.Current, the processing of beneficiation wastewater comparatively the method for widespread usage by natural sedimentation method, neutralization precipitation method and coagulant sedimentation.Natural sedimentation method is to utilize broad place to make suspended substance natural sedimentation in the waste water, and makes labile material natural oxidation; The shortcoming of this method is to need large stretch of soil, and the treatment time is long, easy again polluted underground water resource.Neutralization precipitation method and coagulant sedimentation are that a large amount of medicament of Xiang Shuizhong adding carries out wastewater treatment; Because the adding of medicament has increased processing cost, causes secondary pollution easily, add this method again and can only make portion water discharging, portion water reuse, can not realize whole recycles.
Summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this invention is to provide a kind of processing method of methd for treating mine wastewater by using membrane technology, the water purification that obtains after the processing can be used as production, domestic water.
Realize that the technical scheme that purpose of the present invention adopts is: the technical process of this methd for treating mine wastewater by using membrane technology is: waste water → water reservoir → water transfer pump → mechanical filter → fiber ball filter → activated charcoal filter → accurate filter → reverse osmosis membrane group → water purification; Concrete processing method is earlier beneficiation wastewater to be deposited in the water reservoir that can precipitate elimination bulk foreign material, with water transfer pump the waste water in the pond is flowed to application quartz sand again and leach large particulate matter and some organic mechanical filters in the waste water as filtrate, water after the filtration enters the fiber ball filter that inside is filled with fiber-ball filter media, by the oil slick in the filtrate filtrate in the fiber ball filter and some colloids and organism, water after the filter enters the strainer of filling gac, lean on gac except that the organism in anhydrating, colourity and chlorine residue, water enters the accurate filter of making by mould material then, but directly be impurity in 0.005 millimeter the water greater than filter opening in the elimination water, enter again the reverse osmosis membrane group by principle of reverse osmosis to the heavy metal cadmium in the water, zinc, molybdenum, impurity such as metal ions such as copper and superfine organism and colloid are held back removal, the high quality pure water that obtains is drawn as producing by pipeline, domestic water, the condensed water under holding back is carried out metal recovery.
The invention has the beneficial effects as follows: this processing method has adopted the wastewater processing technology of suitable ore dressing water treatment characteristics, used fibre-ball filtration and membrane separation technique beneficiation wastewater has been carried out multiple-stage treatment, removed the objectionable impurities in the waste water effectively, make the water purification that obtains after the processing can reach national drinking water standard, can be used for fully producing and life, make water resources obtain recycle.Compare the treatment time with other water treatment method short; saved land resources; reduce processing cost, avoided secondary pollution, realized the recycle of water; protected ecotope; save production cost, improved the processing efficiency of waste water, simultaneously; the recovery of the recycle of waste water and metal is combined, created economic benefit and social benefit.
Embodiment
The processing method of a kind of methd for treating mine wastewater by using membrane technology of the present invention, the technical process of this methd for treating mine wastewater by using membrane technology is: waste water → water reservoir → water transfer pump → mechanical filter → fiber ball filter → activated charcoal filter → accurate filter → reverse osmosis membrane group → water purification; Concrete processing method is earlier beneficiation wastewater to be deposited in the water reservoir, make the bulk foreign material be deposited at the bottom of the pond after, with water transfer pump the waste water in the pond is flowed to mechanical filter; Be placed with the quartz sand as filtrate in this mechanical filter, the quartz sand modes of emplacement is a bottom particle diameter 16-20 millimeter, middle level particle diameter 12-16 millimeter, particle diameter 2-5 millimeter at the middle and upper levels, upper strata particle diameter 0.5-0.8 millimeter, the height of each layer is 150 millimeters, filtering velocity be 8-10 rice/hour; Quartz sand by different-grain diameter leaches large particulate matter and some organism in the waste water.Water after the filtration enters the fiber ball filter that inside is filled with fiber-ball filter media, and this fibrous nodules is pricked knot by fiber yarn and formed, and in filtration procedure, the space of filtering layer diminishes gradually along water (flow) direction; By the oil slick in the filtrate fibrous nodules filtrate in the fiber ball filter and some colloids and organism, advantage such as it is good that its filtrate of this kind filter method has an elastic effect, do not emerge, and anticorrosive, the work period is long, and head loss is little.Water after the filter enters the strainer of filling gac, leans on gac except that organism, colourity and chlorine residue in anhydrating; Water enters the accurate filter of making by mould material then, but is impurity in 0.005 millimeter the water greater than the aperture in the elimination water; Entering the reverse osmosis membrane group again uses principle of reverse osmosis impurity such as metal ion such as the heavy metal cadmium in the water, zinc, molybdenum, copper and superfine organism and colloid is held back removal, the high quality pure water that obtains is drawn as production, domestic water by pipeline, and the condensed water under holding back is carried out metal recovery.Reverse osmosis is a kind of separation method that selectively solute in the solution and solvent is separated by means of semi-permeable membranes under pressure.Use this processing method and can reclaim metallics in mine wastewater, production can reach the water purification of national drinking water standard.
