Abstract
The invention discloses filler for sewage treatment. The filler is cuboid, and at least one surface of the cuboid is an inwards bent arc-shaped concave surface. The filler has the advantages that the contact area of the filler with water can be greatly increased, and the adsorption effect can be improved.
Description
Technical field
The present invention relates to the technical field of a kind of sewage disposal, particularly to a kind of filler for sewage disposal。
Background technology
It is currently used for the filler of sewage disposal mainly based on circular, square, rectangle。Singly in operational management engineering, square, rectangular pack are packed together, and between filler, adjacent surface fits tightly, and cause that resistance to water-flow is big, current are short-circuit, greatly reduce the contact area of sewage and filler simultaneously, affect the adsorption effect of filler。Circular filler is unfavorable for the attachment of microorganism, running easily occurs current straight under, the problem of pore plugging, these problems all cause that filler can not give full play to adsorption, ultimately cause system fluctuation of service, and effluent quality is not up to standard。
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of filler for sewage disposal, and this filler can be greatly increased the contact area of filler and water, thus reaching to improve the purpose of adsorption effect。
In order to solve above-mentioned technical problem, the technical scheme is that a kind of filler for sewage disposal, described filler is cuboid, and at least one face of this cuboid is aduncate arc-shaped concave。
As preferably, six faces of described cuboid are arc-shaped concave。
As preferably, described arc-shaped concave curves inwardly 15 °～20 °；The arc length of described arc-shaped concave is 7～10cm。
As preferably, described filler offering several through holes。
As preferably, described through hole is cylindrical。
As preferably, the ratio of the aperture of described through hole and the arc length of described arc-shaped concave is 1～3:7～10。
A kind of filler for sewage disposal, described filler comprises following components: alkali modification attapulgite, natural diatomaceous earth, cement and hydrogen peroxide。
As preferably, the mass ratio of described natural diatomaceous earth, alkali modification attapulgite and cement is 1:3:1.5。
As preferably, the preparation method of described alkali modification attapulgite comprises the following steps: mixed by the weight ratio of 1～10:1～30 by the sodium hydroxide solution of attapulgite and 3～6mol/L, 20 DEG C～40 DEG C constant temperature oscillation several minutes, centrifugation, distilled water flushing precipitates, it is neutral to washing liquid pH, dries, be ground to 80～100 orders。
A kind of method preparing described filler, by proportioning, mixes alkali modification attapulgite, natural diatomaceous earth and cement, obtains compound, add the hydrogen peroxide of described compound gross weight 40%～50%, insert in mould, press mold。
Preparation principle of the present invention is as follows:
Attapulgite has the layer chain structure feature of uniqueness, there is crystal lattice in structure, containing Ca in crystal2+、Fe3+、Al3+, can the pollutant such as active adsorption phosphorus。Attapulgite, after alkali modification, makes needle bar shape group loose porous, increases specific surface area and the absorbability of filler。Containing higher Fe in natural diatom soil structure3+、Al3+, be conducive to the absorption to pollutant such as phosphorus, and kieselguhr have certain cohesive force。Adsorption stuffing makees foaming agent with hydrogen peroxide, makes filler present loose porous form, is greatly increased void content and specific surface area, thus improving the absorbability of filler。Filler is designed to the cambered surface square of middle part perforate, makes can not fit tightly between filler, and the adjacent surface between left and right, upper and lower filler forms a water stream channel, makes current unimpeded, increases the contact area of filler and water simultaneously。
Adopt technique scheme, filler is designed to cambered surface, relatively conventional cuboid filler, surface area increases 20～30%, cambered design makes filler not fit tightly, and the adjacent surface between left and right, upper and lower filler forms a water stream channel, and filler voidage increases more than 10 times, improve because the overstocked current caused short circuit piled up by filler, increase filler simultaneously and amass with water engaging surface。
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention。
In figure, 1-cuboid, 2-arc-shaped concave, 3-through hole。
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further。At this it should be noted that be adapted to assist in for the explanation of these embodiments and understand the present invention, but it is not intended that limitation of the invention。As long as just can be mutually combined additionally, technical characteristic involved in each embodiment of invention described below does not constitute conflict each other。
Embodiment 1
By proportioning, alkali modification attapulgite, natural diatomaceous earth and cement being mixed, obtain compound, add the hydrogen peroxide of described compound gross weight 45%, insert in mould, press mold, after the demoulding, watering moisture-keeping maintaining 6 days, natural air drying, obtain cambered surface square filler finished product。
Wherein, the mass ratio of natural diatomaceous earth, alkali modification attapulgite and cement is 1:3:1.5；The volume by volume concentration of hydrogen peroxide is 0.8%；The preparation method of described alkali modification attapulgite comprises the following steps: mixed by the weight ratio of 5:15 with the sodium hydroxide solution of 5mol/L by attapulgite, 30 DEG C of constant temperature oscillation several minutes, centrifugation, distilled water flushing precipitates, it is neutral to washing liquid pH, dries, be ground to 100 orders。
Embodiment 2
By proportioning, alkali modification attapulgite, natural diatomaceous earth and cement being mixed, obtain compound, add the hydrogen peroxide of described compound gross weight 50%, insert in mould, press mold, after the demoulding, watering moisture-keeping maintaining 8 days, natural air drying, obtain cambered surface square filler finished product。
Wherein, the mass ratio of natural diatomaceous earth, alkali modification attapulgite and cement is 1.5:5:3；The volume by volume concentration of hydrogen peroxide is 1%；The preparation method of described alkali modification attapulgite comprises the following steps: mixed by the weight ratio of 10:30 with the sodium hydroxide solution of 6mol/L by attapulgite, 20 DEG C of constant temperature oscillation several minutes, centrifugation, distilled water flushing precipitates, it is neutral to washing liquid pH, dries, be ground to 100 orders。
