Abstract
A mine sewage depth treatment recycling device belongs to a sewage treatment device and includes a filtering apparatus and a membrane permeability apparatus connected by a pipeline. A lift pump for treated water of front grade is arranged in front of the filtering apparatus and a high lift pump is arranged in front of the membrane permeability apparatus. The back of the membrane permeability apparatus is connected with a clarified box for water yielding. The filtering apparatus is connected with a porcelain filter, an active carbon filter and an ultrafilter in sequence by pipelines. A quartz sand filter is replaced by the porcelain filter, thereby greatly saving the investment cost in mine sewage depth treatment. Combined membrane elements are adopted in the membrane permeability apparatus, thus not only having the advantages of high water yielding quantity and low operation cost, but also leading the water quality to be better than the quality standard of urban water supply.
Description
Technical field
The utility model belongs to waste disposal plant, refers in particular to a kind of mine advanced treatment of wastewater reclamation set.
Background technology
The mine sewage disposal generally divides two portions, be preprocessing part and advanced treatment part, preprocessing part reaches the reclaimed water standard by common process such as flocculation, precipitation, filtrations, in order further to reach the Urban water supply water quality standard, need carry out advanced treatment, current, advanced treatment is that the water after prime is handled is promoted in the more medium filter, through quartz sand filtration, activated carbon filtration, ultrafiltration is then removed molecule with accurate filter again, pumps up to enter the processing of membrane permeation device.Adopt quartz sand filtration because of elder generation in this technology, treatment effect is restricted, in order to satisfy the water inlet requirement that film is handled, also be equipped with ultra-filtration equipment behind the activated carbon filtration, can attended operation in order to protect postorder not cut off the water supply, other is required to be ultrafiltration and sets water tank separately, on the one hand increased investment in fixed assets greatly, on the other hand, because of the ultra-filtration equipment backwash frequent, water consumption is a lot, and technology running cost is big; Secondly, in the technology in the membrane permeation device two-segment film all adopt single film, can make water production rate low with a kind of film, system's operating pressure raises, whole membrane permeation is short device lifetime.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, provide a kind of cost of investment low, the processing efficiency height, the mine advanced treatment of wastewater reclamation set that working cost is few, main innovation is to filter selects for use porcelain sand to filter earlier, because of the prosperity of porcelain sand micropore, porosity is big, have good adsorptive power, its filtration treatment is effective, does not need to join in addition ultra-filtration equipment in the post-order process, just can satisfy the water inlet requirement of membrane permeation treatment unit, greatly reduce cost of investment, in addition, in the membrane permeation device, adopt built-up type assembling membrane element, promptly two sections are adopted different films respectively, improve water production rate, reduce running cost.Specifically implement like this: mine advanced treatment of wastewater reclamation set, the filtration unit, the membrane permeation device that comprise pipe connection, be equipped with the lift pump of prime treating water before the filtration unit, be equipped with high-pressure pump before the membrane permeation device, connect the water outlet filtered water tank behind the membrane permeation device, it is characterized in that filtration unit is successively by porcelain filter, activated charcoal filter, accurate filter order pipe connection.Porcelain sand in the porcelain filter is the uniform spherical particle, is the multiple spot contact between the sphere, porous nickel, and the many sinuate passages of intermediate formation, circulation distance during current process filtering layer is for impurity causes a very ideal mode of deposition.There are many micropores on porcelain sand surface, makes suspended substance be easy to be held back by porcelain sand surface adsorption, and forms regeneration membrane, and super retaining power is big to the filtration effect, and porcelain sand specific surface area is approximately 8.5cm
2/ cm
3, its maximum saturation body refuse amount is 30.5kg/m
3, be general quartz sand can not compare.Again because porcelain sand is spherical, flow resistance is little, and self light specific gravity is when carrying out back flushing, can borrow self rolling and mutual friction mutually, make the body refuse that is attached on the sphere be easy to be cleaned and remove, the backwash time is short, and the water consumption is little, effective, the rate of expansion of filtrate only 10% during backwash, and much smaller than quartz sand filter media rate of expansion 40-50%, backwash intensity is 4.5-6L/S.m
2, also much smaller than quartz sand backwash intensity 12-15L/S.m
2
Delivery turbidity＜the 0.5NTU of porcelain sand filter, back level membrane permeation device water inlet requirement can be satisfied in SDI＜3.Porcelain sand in the porcelain sand filter can be not damaged when operation, the cycle of operation is long, be about 10 years and do not change, general quartz sand will be changed once or increase a part every year, dispose the porcelain sand filter in the technological process and can save ultra-filtration equipment one, can save investment 30-50%, water consumption, power consumption are also greatly saved.
Membrane permeation device of the present utility model is to adopt built-up type assembling membrane element, and promptly first section and second section is adopted different membrane elements, adopts the high film of the relative ratio of desalinization of the big flow of ultralow pressure as first section, second section lower film of the relative ratio of desalinization of employing, on the contrary also can.The membrane permeation device of this built-up type assembling membrane element, membrane element consumption about 15% in can the minimizing system, reduce investment, and water production rate height, system's operating pressure is lower, the work-ing life of membrane permeation device is also long, and through the water outlet behind the membrane permeation device, the water quality leading indicator all satisfies and is better than the Urban water supply water quality standard.
The utility model is equipped with the water cycle connecting tube between the washing unit water outlet of the backwash water tank of porcelain filter, activated charcoal filter and backwashing pump and membrane permeation device, the water outlet of the washing unit of membrane permeation device can be used as the backwashing water of porcelain filter by pipeline, make whole technology compacter, minimization of cost.
The utility model adopts porcelain filter to substitute the quartz sand filtration device just, make and saved cost of investment in the mine advanced treatment of wastewater greatly, use the combination membrane element in the membrane permeation device, not only make the water production rate height, running cost is low, and effluent quality is better than the Urban water supply water quality standard.
