Background technology
The absorption method dephosphorization is the most effectively one of dephosphorizing method of eutrophication water, and red mud particularly changed red mud be present focus and field, forward position to the absorption research of phosphorus.To the adsorption applications of red mud, be divided into two kinds at present substantially, a kind of is to fire red mud porcelain granule to be spread in the sewage, sintering procedure need drop into a large amount of funds and manpower and materials, and is comparatively complicated; Another is that red mud is carried out modification, as adopts method modifications such as acid modification agent commonly used or heating, and the red mud after the modification directly is added in the sewage and adsorbs.Along with the continuous progress of method of modifying, the space that a kind of method in back develops is increasing, and the progressively raising of adsorption effect more and more comes into one's own, but also has the problem that needs power whipping device, the red mud recovery inconvenience of processing back etc. in actual applications.
Summary of the invention
The present invention is directed to the problem that red mud adsorption and dephosphorization technology exists in the existing sewage disposal, a kind of advantages of good adsorption effect is provided, is convenient to the spiral suspended type red mud membrane bag adsorption and dephosphorization apparatus that red mud reclaims.
Spiral suspended type red mud membrane bag adsorption and dephosphorization apparatus of the present invention is by the following technical solutions:
This device is made up of film bag, hanger and float, hanger is hung with the film bag below by rope, float be connected hanger above, be provided with support in the film bag and be filled with changed red mud, be suspended on each film bag below the hanger when overlooking from inside to outside in the shape of a spiral shape distribute, shape distributes the suspension height of each film bag by putting in order also in the shape of a spiral simultaneously.
The film bag can adopt nylon, bolting silk, terylene, non-woven fabrics, 3 D filter cloth etc. to make, spherical in shape or the square and acid and alkali-resistance of support in it, and the purpose of putting support is to keep the shape of film bag in current.
Changed red mud adopts existing method modification commonly used.
Hanger adopts thistle board or reticulation, and material can be lightweight plank or plastic plate,
During use, whole device is positioned in the sewage lagoon, at the bottom of whole device under the effect of float can not be sunken to the pond, but free-floating moves in sewage, thereby reaches ideal adsorption treatment effect.Can in sewage lagoon, set up baffle plate,, better make the film bag be distributed in the pond, can avoid simultaneously that rope twines mutually between the different floats the zoning, pond.Adjust the quantity and the distribution of facial mask bag under the hanger according to the pollution level of water and the factors such as the degree of depth of handling the pond, can hang a plurality of film bags on the rope, better to reach adsorption effect.After red mud reaches maximum adsorption, can directly from the pond, pull float out, take off the red mud bag, outwell used red mud, clean the film bag, changing red mud again can come into operation once more.
Also can adopt the method for direct suspension, in the pond, draw in the net wiring, with rope with the film bag in the shape of a spiral shape hang on netting twine below.
The present invention adopts film bag parcel red mud to carry out dephosphorization absorption, the filtered and recycled problem that can effectively avoid adsorbing the back red mud, convenience simple to operation.Simultaneously, in the film bag, put into sphere or quadrate support, can keep the shape of film bag under the waterpower state, guarantee the distribution of red mud.And the three-dimensional in length and breadth spiral of film bag can make the red mud in the film bag be distributed in each layer of sewage lagoon, thereby reaches red mud adsorption treatment phosphorus effect to greatest extent.In addition, made full use of the effect of current to the film bag, and the floating effect of float in the current, the film bag is fully moved freely under the effect of float and current, water is evenly adsorbed, therefore can increase power and stir facility, can reduce fund input effectively.

Embodiment
Structure of the present invention as shown in Figure 1, this device is made up of film bag 1, hanger 3 and float 4.Float 4 be connected hanger 3 above, be used for whole device is suspended in the pond.Hanger 3 adopts lightweight plank or plastic plate to make.Film bag 1 adopts flexible materialss such as nylon, bolting silk, terylene, non-woven fabrics, 3 D filter cloth to make, and its inner support has the support of sphere or quadrate acid and alkali-resistance, such as the support made from rigid plastics, to keep the shape of film bag in current.Fill full changed red mud in the film bag 2.As shown in Figure 2, each film bag 1 by rope 2 hang on hanger 3 below, each film bag 1 from inside to outside in the shape of a spiral shape distribute and (to overlook effect, promptly hang upper end shape arrangement in the shape of a spiral in a plane of the rope of each film bag), make film bag uniform in lateral extent, the suspension height difference of each film bag simultaneously, shape distributes by putting in order also in the shape of a spiral, make the film bag at the vertical uniform liter of scope, thereby constitute interior three-dimensional uniform of the horizontal and vertical scope of film bag.One deck can be adopted or multilayer is identical or the film bag of differing materials according to the sewage situation, a plurality of film bags can be hung on the same rope, better to reach treatment effect.
The process that the present invention disposes of sewage is:
Baffle plate or retaining line are set in the pond, artificially the pond is divided into a plurality of zones, place one to two device of the present invention in each zone, thereby make the film bag be distributed in the pond better, also can avoid because current are too drastic simultaneously, the rope between the different floats that float too much causes twines problem mutually.Sewage enters from the water inlet in pond, through the adsorption of red mud in the film bag 1, gets rid of the phosphorus in the sewage.The three-dimensional helical pattern that the film bag adopts can make the red mud layering be dispersed in the sewage to greatest extent, can the phosphorus of each water layer in the pond be adsorbed.The water of handling well flows out from water outlet 9, need not to filter red mud.After red mud reaches maximum adsorption, can directly from sewage, pull the film bag out, pour out the red mud after the use, the film bag is cleaned slightly, can change red mud and come into operation once more.
