Abstract
The invention provides a suspended inorganic filler for sewage treatment, which is composed of montmorillonite powder, fly ash, activated carbon, biological bacterium sludge, water glass, a foaming agent, a titanium dioxide sol and water. The preparation method comprises the following steps: adding the montmorillonite powder, fly ash and activated carbon into a stirrer, adding water, stirring, and slowly adding the water glass; and stirring uniformly, adding the titanium dioxide sol, foaming agent and biological bacterium sludge, stirring uniformly, and standing for 24 hours.
Description
Technical field
The present invention relates to a kind of sewage disposal filler, is more particularly a kind of suspension mineral filler for sewage disposal, belongs to environmental protection and field of energy-saving technology.
Background technology
At present, biological sewage treatment adopts biological contact oxidation process, it is large to there is investment in its technology and equipment of traditional biological method for treating waste water, consume energy high, the shortcomings such as complex management, to be attached to the microbial film on carrier, a kind of High-efficient Water treatment process of purification of organic waste water, now be widely used in textile printing and dyeing, wool spinning is knitting, beer food, petrochemical complex, process such as medicine papermaking and sanitary sewage etc., and obtain obvious social effect, the method filler used has rock wool, sandstone, wood palm fibre, soft-filler, filler lift onlift-off type filler and the ball floats such as combined stuffing, polyhedron empty ball, the suspension fillers such as soft-filler, lift onlift-off type filler cost is low, two ends are needed to be fixed on sewage lagoon inwall by through metal during use, long period of soaking is in sewage, support is very easily corroded, support is easily caused to cave in, filler is caused to be scrapped.
For the sewage of difficult degradation, particularly treatment of dyeing wastewater difficulty is large, investment and running cost high, along with the development of science and technology, increasing Persistent organic pollutants in dyeing, add the difficulty for the treatment of of dyeing wastewater as additive application.For this kind of waste water, adopt conventional biochemistry, materializing strategy mode at present, but all there is the problem that processing cost is high, be difficult to reach better treatment effect, and the present invention proposes to solve above-mentioned technical problem just.
Summary of the invention
An object of the present invention is the technical problems such as above-mentioned processing cost is high, mass-transfer performance is poor in order to solve, not corrosion-resistant, work-ing life is short, replacing is inconvenient, and a kind of suspension for sewage disposal proposed inorganicly is filled out.
Technical scheme of the present invention: montmorillonite powder, flyash and gac are added in agitator, add water stirring, slowly adds water glass; Add whipping agent, the colloidal sol of titanium dioxide and biological bacteria mud after stirring, after stirring, leave standstill 24 hours.
Beneficial effect of the present invention:
Owing to employing the TiO2 with photocatalysis, under solar light irradiation, the sewage to difficult degradation can be realized, the particularly photocatalytic degradation of dyeing waste water, simultaneously owing to being embedded with microorganism in load layer, make biological treatment closely be coupled with photodegradation, act synergistically, improve the treatment effect of dyeing and printing sewage, improve processing efficiency.For in sewage treatment process, degradation product occurs after redox reaction on TiO2 surface, and valence band is got back electronics, recovers virgin state.When light irradiates again, can there is same transition again in the electronics on valence band, such that TiO2 is reusable does not affect that it is active.
Specific embodiment
Below by embodiment, the present invention is explained further, but do not limit the present invention.
Embodiment 1;
Montmorillonite powder 61
Flyash 50
Gac 52
Biological bacteria mud 42
Water glass 20
Whipping agent 21
The colloidal sol 12 of titanium dioxide
Appropriate water.
Preparation scheme: montmorillonite powder, flyash and gac are added in agitator, add water stirring, slowly adds water glass; Add colloidal sol and the biological bacteria mud of titanium dioxide after stirring, after stirring, leave standstill 24 hours.
The present invention is that the energy floats on the water surface with sunlight, without the need to applying power equipment, without the need to fixed sturctures such as truss, greatly reduces processing cost.
Embodiment 2:
Montmorillonite powder 64
Flyash 55
Gac 54
Biological bacteria mud 46
Water glass 24
Whipping agent 26
The colloidal sol 16 of titanium dioxide
Appropriate water.
Preparation scheme is the same.
The present invention is in sewage treatment process, and degradation product is after redox reaction occurs on TiO2 surface, and valence band is got back electronics, recovers virgin state.When light irradiates again, can there is same transition again in the electronics on valence band, such that TiO2 is reusable does not affect that it is active.
Embodiment 3:
Montmorillonite powder 70
Flyash 59
Gac 58
Biological bacteria mud 50
Water glass 29
Whipping agent 30
The colloidal sol 18 of titanium dioxide
Appropriate water.
Preparation scheme is the same.
The present invention due to density little, floating with the water surface on, without additional binding, therefore it is in fluidized state in water, and mass-transfer performance is good, without the need to fixing truss, at the sewage for difficult degradation, particularly dyeing and printing sewage process aspect, has cost low, processing cost is low, long service life, changes the advantage convenient, treatment effect is good.Thus solve existing filler and easily corroded by waste water because of fixing truss, cause the problem that the work-ing life of filler is short.
Foregoing be only the present invention conceive under basic explanation, and according to any equivalent transformation that technical scheme of the present invention is done, all should protection scope of the present invention be belonged to.
