Abstract
A process of treating mine wastewater through applying a membrane technique is disclosed. The process includes allowing mine wastewater to sequentially flow through a water storage tank, a water output pump, a mechanical filter, a fiber ball filter, an activated carbon filter, a precision filter and a reverse osmosis membrane unit to obtain clean water. The mechanical filter is used for removing large particles and some organic matters in the wastewater. The fiber ball filter is used for removing floating oils, some colloids and organic matters in the wastewater. The activated carbon filter is used for removing organic matters, chrome and residual chlorine in the wastewater. The fine filter is used for removing impurities with a size of 0.005 mm or above. The reverse osmosis membrane unit is used for capturing and removing heavy metals such as cadmium, zinc, molybdenum and copper. The obtained clean water with high quality is discharged through pipes for industrial and domestic use. Heavy metals can be recovered from concentrated water. The method is advantaged by a high efficiency, a low cost, no secondary pollution, water recycle and reutilization and capability of protecting the ecological environment and increasing economic benefit.
Description
Technical field
What the present invention relates to is a kind of process of processing mine wastewater, specifically a kind of process of methd for treating mine wastewater by using membrane technology.
Background technology
Metal mine, particularly sulfide metal mine, all can produce acid waste water when ore dressing. In these waste water, contain the metal ions such as copper, zinc, molybdenum, and suspension content is high, not free settling, presents finely divided glue; Feature is that discharge capacity is large, and directly contaminated environment is being destroyed the water resource of growing tension. Current, the method that the processing of beneficiation wastewater is comparatively generally applied is by natural sedimentation method, neutralization precipitation method and coagulant sedimentation. Natural sedimentation method is to utilize broad place to make the suspension natural sedimentation in waste water, and makes labile material autoxidation; The shortcoming of this method is to need large stretch of soil, and the processing time is long, again easy polluted underground water resource. Neutralization precipitation method and coagulant sedimentation are that Xiang Shuizhong adds a large amount of medicaments to carry out wastewater treatment; Due to adding of medicament, increase processing cost, easily cause secondary pollution, then add this method and can only make part water discharge, the reuse of part water, can not realize all and recycling.
Summary of the invention
In order to solve the deficiencies in the prior art, the object of this invention is to provide a kind of process of methd for treating mine wastewater by using membrane technology, the water purification obtaining after processing can be done
For production, domestic water.
Realizing the technical scheme that object Bian of the present invention uses is: the technological process of this methd for treating mine wastewater by using membrane technology is: waste water cistern water-delivery pump mechanical filter fiber ball filter active carbon filter accurate filter one reverse osmosis membrane group water purification one by one, concrete process is first beneficiation wastewater to be deposited in the cistern that can precipitate elimination bulk foreign material, with water-delivery pump, the waste water in pond is flowed to application quartz sand again and leach large particulate matter and some organic mechanical filters in waste water as filtrate, water after filtration enters inside and is filled with the fiber ball filter of fiber-ball filter media, by the oil slick in the filtrate filtrate in fiber ball filter and some colloids and organic matter, water after filter enters the filter of filling active carbon, remove the organic matter in anhydrating by active carbon, colourity and chlorine residue, then water enters the accurate filter of making by membrane material, can in elimination water, be greater than impurity in the water that filter opening footpath is 0.005 millimeter, enter again reverse osmosis membrane group by principle of reverse osmosis to the heavy metal cadmium in water, zinc, molybdenum, the metal ions such as copper and the superfine impurity such as organic matter and colloid are held back removal, the high-quality pure water obtaining is drawn as production by pipeline, domestic water, condensed water under holding back is carried out metal recovery.
The invention has the beneficial effects as follows: this process has adopted the wastewater processing technology of applicable ore dressing water treatment feature, apply fibre-ball filtration and membrane separation technique beneficiation wastewater has been carried out to multistep treatment, effectively remove the harmful substance in waste water, make the water purification obtaining after processing can reach national drinking water standard, completely can for generation of with life in, water resource is recycled. Processing time is short compared with other method for treating water; save land resource; reduce processing cost, avoided secondary pollution, realized recycling of water; protect ecological environment; save production cost, improved the treatment effeciency of waste water, simultaneously; recycling with the recovery of metal of waste water combined, created economic benefit and social benefit.
Detailed description of the invention
The process of a kind of methd for treating mine wastewater by using membrane technology of the present invention, the technological process of this methd for treating mine wastewater by using membrane technology is: waste water cistern water-delivery pump mechanical filter fiber ball filter active carbon filter ^ accurate filter reverse osmosis membrane group water purification one by one one by one; Concrete process is first beneficiation wastewater to be deposited in cistern, after making bulk foreign material be deposited at the bottom of pond, waste water in pond is flowed to mechanical filter with water-delivery pump, in this mechanical filter, be placed with the quartz sand as filtrate, quartz sand modes of emplacement is 16 1 20 millimeters of bottom particle diameters, middle level particle diameter 12-16 millimeter, particle diameter 2-5 millimeter at the middle and upper levels, 0.5-0.8 millimeter of upper strata particle diameter, the height of each layer is 150 millimeters, filtering velocity is 8-10 ms/h, leaches large particulate matter and some organic matters in waste water by the quartz sand of different-grain diameter. Water after filtration enters inside and is filled with the fiber ball filter of fiber-ball filter media, and this fibrous nodules is formed by filament ligation, and in filter process, the space of filtering layer diminishes gradually along water (flow) direction; By the oil slick in the filter media fibre ball filtrate in fiber ball filter and some colloids and organic matter, the advantage such as it is good that this kind of its filtrate of filter method has elastic effect, do not emerge, and anticorrosive, the work period is long, and the loss of flood peak is little. Water after filter enters the filter of filling active carbon, removes organic matter, colourity and the chlorine residue in anhydrating by active carbon; Then water enters the accurate filter of making by membrane material, is greater than aperture in can elimination water and is impurity in the water of 0.005 millimeter; Enter again reverse osmosis membrane group application principle of reverse osmosis the metal ions such as the heavy metal cadmium in water, zinc, molybdenum, copper and the superfine impurity such as organic matter and colloid are held back to removal, the high-quality pure water obtaining is drawn as production, domestic water by pipeline, and the condensed water under holding back is carried out metal recovery. Counter-infiltration is a kind of separation method selectively solute in solution and solvent being separated by means of pellicle under pressure. Apply this process and can in mine wastewater, reclaim metallics, production can reach the water purification of national drinking water standard.
