Abstract
The present invention relates to the improvement of a water treating device and ferrous stuffing of an inner electrolytic bed, which is characterized in that the water treating barrel is provided with a shorter inner barrel in the axial direction; a sludge collecting hopper is arranged at the bottom of the water treating barrel; the ferrous stuffing is a polyhedron having a three-dimensional structure and occupying large space and is arranged on the sandwich layer between the inner barrel and an outer barrel; an air distributing device is arranged at the bottom of the sandwich layer between the inner barrel and the outer barrel. The water treating device for an inner electrolytic bed overcomes the inherent defects of easy cicatrization and passivation of the ferrous stuffing and has the advantages of large material transfer area, high keeping activity and good treating effect.
Description
Technical field
The present invention relates to a kind of wastewater treatment equipment, especially internally the improvement of bed electrolysis water treatment device and iron filler.
Background technology
Chinese patent 98242534 disclosed a kind of lasting highly active Fe bed apparatus for treating water, for guaranteeing that the iron filler has high activity, employing is returned treating water at a high speed by extracorporeal circulation, with high flow velocity the iron filling surface is advanced flushing, desire is discharged iron filling surface accumulative bubble hydrogen and deposit dirt flushing, the effect of mass transmitting that keeps the high reactivity and the raising filler of iron filler.This by filtrate extracorporeal circulation raising flow velocity cleaning filler, though filling surface is had stronger cleanup action, but this end, rush to floating cleaning way, easily cause the obstruction of three-phase (vapour, water, the dirt) separator at water treatment device top, and heavier dirt is difficult for going out clearly external, still can fall the upper strata filling surface, influence treatment effect.Secondly, dress iron filler is the sheet erratic composition in this treatment unit, the tap density height, and the overlapped phenomenon of filling surface is serious, and it is few to participate in the effective contact area of mass transfer.Besides, the overlapped surface void that causes of filler is little, and dirt is difficult to obtain effective cleaning, and the inner dirt of packing layer is discharged difficulty, can reduce the filler activity, and intercept the electrolysis mass transfer of filler and treating water.Iron filler tap density increases, and also can increase filler and throw in once investment, but treatment effect does not obtain increasing.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of and can effectively guarantee the high reactivity of iron filler and the interior bed electrolysis water treatment device of mass transfer ability.
The object of the invention realizes, the main improvement is flushing changes internal recycle into by external following to filler, and the blowdown sludge hopper is set in the treatment unit bottom, the iron filler adopts nature tap density at random low, filler is piled up the high three-dimensional arrangement polyhedron of voidage, as big three-dimensional multiaspect fillers of various spaces occupy-place such as cuboid, arcuation body, triangular prism, multiple edge body, circle (awl) body, prismatoid, crosswises.Specifically, internal electrolytic iron bed apparatus for treating water of the present invention, comprise water treatment cartridges and built-in iron filler, and Inlet and outlet water device, it is characterized in that said water treatment cartridges axially is provided with the inner core that highly is lower than cylindrical shell, sludge hopper, said iron filler are arranged at said water treatment cartridges bottom is the big three-dimensional arrangement polyhedron of space occupy-place, place interlayer or inner core between inner/outer tube, said inner core and inner/outer tube interlayer bottom are provided with aerating apparatus.Design can have two kinds of basic structure forms according to the present invention, and a kind of is that the iron filler is placed the inner/outer tube interlayer, and a kind of is that the iron filler is placed inner core, does not have essential distinction between the two in the present invention's design.When disposing of sewage, sewage is entered by iron packing layer one end, the iron packing layer of under the air-flow plug-flow, flowing through, fully contact with the iron filler and to carry out electrolytic reaction, and the circulation space by non-placement filler refluxes, make treating water in device, form internal recycle, reach with the abundant electrolysis mass transfer of iron filler filler is washed; During backwash, back flushing source of the gas in ON cycle space forms the high speed air water stream reverse with handling current, refluxes between the circulation space and packing layer, and the iron filler is carried out back flushing, washes away and takes the dirt that is deposited in the iron filling surface out of.Handle the macrobead dirt of taking out of with the positive and negative circulation of anti-cleaning, then sink down into sludge hopper, thereby effectively guaranteed the high reactivity and the high pass mass-energy power of iron filler in action of gravity.
Take the deposition of dirt separating effect out of for improve cleaning, the present invention bottom sludge hopper is preferably made pyramidal structure, and can therein swash plate be set or inclined tube helps tripping device.For eliminating the foam that microelectrolysis process produces, can the froth breaking annular groove be set, interior placement defoamer in device urceolus upper inner.
The said iron filler of the present invention is three-dimensional polyhedral shape, be meant and have apparent in view three-dimensional multi-plane structure, filler is under stacking states at random naturally, and the contact surface of adjacent two blocks of fillers is portion or all overlapping greatly not, for being different from the description that flats and fine-grannular filler are done.This three-dimensional polyhedral shape filler, under stacking states at random naturally, (especially between filling surface) space is big between each filler, big of filler adjacent contact face or whole overlapping probability are little, thereby guaranteed the tap density that filler is low, and big mass transfer area, dirt is also easily discharged between packing layer.The said three-dimensional multiaspect filler of the present invention is excellent with criss-cross construction especially wherein, not only have than low bulk density and big surface-area, and unit weight is light, casts easy.Right-angled intersection, a kind of easy method has " recessed " word structure by the iron filler is cast, and two blocks of " recessed " shape ingot pigs is intersected plug together." recessed " sheet thickness is excellent with 5-20mm especially.The said right-angled intersection of the present invention is not to intersect on the mathematical concept to be the right angle, can be the distortion of right angle right-angled intersection yet.
Internal electrolytic iron bed apparatus for treating water of the present invention, owing to adopt inside and outside sleeve jacket structured, increase by a water cycle space in the iron packing layer centre or the outside, and adopt nature tap density at random low, the filling surface space is big, the three-dimensional multiaspect iron filler that occupy-place is big and below iron filler and water cycle space aerating apparatus is set promotes treating water by air-flow and forms cycle of treatment and backwash cycles through the circulation space at packing layer.Not only keep the advantage of internal electrolytic iron bed apparatus for treating water, and overcome the easily inherent defect of " scabbing ", " passivation " of interior bed electrolysis iron filler.Make internal electrolytic iron bed apparatus for treating water, iron filler mass transfer area is big, the active height that keeps, and treatment effect is good.And air purge is counter circulates, and cleans thoroughly, intensity is high, and anti-scavenging period is short, the efficient height.The bottom sludge hopper, the blowdown thing is thorough, and dirt can not return packing layer.
Below in conjunction with several indefiniteness embodiment, advance the present invention is described.
