Description
Technical field
The invention belongs to environmental engineering water body recovery technique field, relate to a kind of mud-zeolite purified water type eco-concrete and preparation method thereof.
Background technology
In recent years, along with the development of social economy and urbanization, China river, lake, reservoir water environmental situation are on the rise.How to prevent and treat water pollution and the research of the recovery technique of polluted-water has been become to the emphasis that water environment protection is studied.The later stage sixties 20th century, the western developed country such as Germany and Switzerland heightened awareness is the basic reason that causes stream pollution to concrete revetment, start ecological principle to be applied to civil engineering work, recover the experimental study of the damaged riverside ecosystem, in eighties of last century, proposed " natural type shore protection " technology the end of the eighties; The country concrete river course that all extensive dismounting has been built such as the nineties in 20th century Germany, the U.S., Japan, France, Switzerland, Austria, Holland etc., carries out ecological recovery to it.The U.S. and Japan's working actively and fruitful in this respect, riverbank ecotope has obtained good recovery.Wherein, first Japan proposed " hydrophilic " idea, ecological revetment technology is applied in the construction of urban river, and puts into practice, and released eco-concrete.
Eco-concrete is by material screening, add functional additive, adopt certain technique producedly to have special construction and function, carrying capacity of environment is little, ecotope Harmony is high, and the concrete that can contribute for environmental protection.Due to the vesicular structure of eco-concrete, various microorganisms can be attached to up one-tenth microbial film, when this cellular concrete is for river, and lake, in the time of in the water of wetland and seashore, water quality is purified the various physics chemical action by these biologies.
Zeolite has absorption and ion mapping function, and ammonia nitrogen is had to good removal effect, is the good material of purification of water quality.Mud is the fittings after sewage disposal, is a kind of extremely complicated heterogeneous body being comprised of organic relic, bacterium thalline, inorganic particle, colloid etc.Because mud organic substance content is high, it is smelly easily to degenerate, if mud is not carried out to ultimate disposal, again bring pollution will to environment.Landfill be take as main to the disposal of mud in China at present, and has a small amount of compost and burning.Mud is useful surplus resources, how to avoid the secondary pollution of sludge creation and rationally utilizes the effective constituent in mud, and be one of study hotspot urgently to be resolved hurrily for a long time.Having research is that raw material making is non-burning brick by mud, and intensity is high, good endurance.Take natural zeolite and excess sludge prepares eco-concrete as raw material, has concurrently and plants raw and two kinds of functions of water purification, while being applied to the situations such as river channel ecology bank protection, purifying eutrophication water body and greenbelts on river bank is had to wide future in engineering applications.
Summary of the invention
The object of the invention is, for the low drawback of current Sewage Treatment by Using Eco-concrete performance, provides a kind of mud-zeolite purified water type eco-concrete and preparation method thereof.
Technical scheme of the present invention is:
Mud-zeolite purified water type eco-concrete, this mud-zeolite purified water type eco-concrete, comprises following material, by weight meter:
Described mud is the excess sludge that waste water produces after second-stage treatment, and its water ratio is 20～30%, and its composition mainly contains SiO
2, CaO, Fe
2o
3, Al
2o
3, SO
3, P
2o
5, K
2o and MgO.
Described coarse aggregate is that particle diameter is the zeolite of 20～30mm.
After above-mentioned material stirring is even, use forming mould casting, the demoulding, maintenance is no less than 28 days under field conditions (factors), obtains mud-zeolite purified water type eco-concrete.
Described cement type is ordinary Portland cement.
Described water reducer is high-efficiency water-reducing agent of poly-carboxylic acid, and water-reducing effect reaches more than 20%.
The described method of stirring is: first by whole coarse aggregates and whole mud mix and blend 1～2min; Then add total Water 1/4,1/4 and cement total amount of water reducer total amount 1/2, stir 1～2min; Add again total Water 1/4,1/4 and cement total amount of water reducer total amount 1/4, stir 1～2min; Finally add remaining water, remaining water reducer and remaining cement, stir 1～2min to mixing completely.
Effect of the present invention and benefit are:
1. present method combines the characteristic that dewatered sludge has certain water ratio and strong water suction, and concrete preparation only needs a small amount of additional moisture, is beneficial to preparation and initial stage moulding, dry;
2. in concrete preparation process, due to mud dewater gradually after volume-diminished, be beneficial to self-assembling formation porosity characteristic in concrete formation.The eco-concrete porosity of preparation is about 18～22%, thereby has larger specific surface area, and pollutent is had to good adsorption effect.
3. utilize absorption and the ion exchanging function of zeolite, further improve its decontamination effect improving to water pollutant.
4. after moulding, in cellular concrete, mud can slowly-releasing N, P etc., promotes microorganism colonization growth, relies on biochemical action to purify waste water;
When 5. prepared by biological concrete, be the process to sludge treatment and recycling, have the advantages that to turn waste into wealth;
6. the method technique is simple, and finished product is cheap, and the eco-concrete of preparation can be for Channel slope nursing greening, natural water purification of water quality and restoration of the ecosystem etc.
