Description
Technical field
The present invention relates to a kind of ecological bank protection material and preparation method that can receive the pollutents such as water body nitrogen phosphorus.Technical field belongs to river regulation, eco-concrete and environment-friendly materials field.
Material of the present invention has the material of special grating and consolidating material to make; its mechanical property is in meeting engineering service requirements; there is cellular structure, porous and continuous feature and good water-permeable and ventilation property; plant and microorganism can grow therein; can ensure the safety and stablization of river bank slope; can, for the restoration of the ecosystem of river bank slope provides favourable condition, protect water ecological setting and the effect that improves water body self-purification ability thereby play again.
Background technology
For a long time, for effectively preventing erosion, ensure river bank slope safety and stablization, conventionally adopt the material revetment river bank slopes such as conventional concrete or cemented rock, the disadvantage of these ways is, it,, only from meeting the stability of river course bank slope and the angle of river course flood water drainage function is designed and constructed, is seldom considered environment and ecological impact.
Along with socioeconomic development, the ecological revetment technology based on harmony between man and nature development starts to obtain people's extensive concern.Ecological slope protection is exactly eco-concrete, also within nearly more than 10 years, carries out about eco-concrete development research.Abroad begin one's study and can improve the concrete material of water quality from the nineties in 20th century, wherein Japan maintains the leading position.Nineteen ninety-five, Japan proposed the concept of eco-concrete.1995 Japanese Nagasaki Universities have carried out eco-concrete test in place, find that eco-concrete has the function of enrichment nutritive substance.Foreign applications is generally coarse porous concrete in the eco-concrete of water treatment, has a large amount of communicating apertures in concrete, therefore has good water-permeable and relies on physics, chemistry and the biochemical action of coarse porous concrete to reach the object of water purification.But external practical application is less, and major cause is that the solid matter in sewage is deposited on concrete, can stop up very soon the hole of coarse porous concrete, makes it lose water purification function; And common coarse porous concrete purifying water effect (especially turbidity etc.) is desirable not enough, concrete calcium ion in flowing water runs off in a large number.Hydrolysis product of cement is decomposed and cause strength decreased until destroy, so concrete weather resistance is inadequate.
Summary of the invention
The object of the invention is to open a kind of prepare burden, environment-friendly high-efficiency simple, with low cost with proportioning, and can receive bank protection material and the making method of the pollutents such as water body nitrogen phosphorus as ecoalimental matrix.This material receives unit take waterworks sludge waste and Zeolite modifying material as nutritive element core, and carry out organic proportioning and make with materials such as cement, its mechanical property is in meeting engineering service requirements, can receive water body nitrogen phosphorus nutrition element and organic matter, there is cellular structure, porous and continuous feature and good water-permeable and ventilation property simultaneously, plant can grow therein, reaches bank protection and improves self purification of water body function, ensures the long-lasting performance of river improvement engineering.
In order to realize above-mentioned target, the present invention takes following technical solution:
A kind of ecological bank protection material that can receive the pollutents such as water body nitrogen phosphorus, build levee slope Eco-Environment System, improve water body self-purification ability, it is characterized in that containing aluminium sesquioxide and iron oxide modified special composition in core material, can enrichment water body in phosphoric and organic matter; Secondly the zeolite after modification has and receives water body nitrogen element and organic structure; And cement in batching and the honeycomb structure of plant type whipping agent to material, permeable and ventilation property and mechanical property play control action kou.In engineering application, be built into the bank protection structure that " absorbing fixing nutritive element and organic biological self reproducing one purifying water body " has ecological functions.
Material making method is: by the ageing of waterworks sludge nature to water ratio below 40%, mud granule (crossing 200 orders) after ageing drops into natural zeolite (crossing 200 orders), the ratio that both mix is 3: 1～4: 1 (weight), compound is put into baking oven dries at 100 ℃, put into again muffle furnace roasting 1.5 hours at 300 ℃, the elementary material of cooling rear formation.The elementary material and the 525R normal silicate that form are 8: 1～12: 1 by weight ratio, form secondary material; Secondary material and water loss weight proportion are 3: 1～4: 1, form grog.Grog and plant type whipping agent weight proportion are 1000: 2～1000: 5, form ecological bank protection material.
The present invention has following advantage:
1, utilize iron useful in waterworks sludge, aluminium, silicon, carbon, calcium etc. can receive the feature of nutritive element, realize turning waste into wealth of mud, the heat modification of mud and natural zeolite is further strengthened it and received simultaneously the level of nutritive element, set up the matrix environment of ecosystem growth demand.Therefore, the present invention have efficiently, the outstanding advantage of low consumption and ecological, environmental protective.
2, by 525R normal silicate and the cellular structure and material of plant type whipping agent control aperture, reach good water-permeable and ventilation property, realize the mechanical property of material and the ecosystem grow demand humidity, moisture and air.Realize bank protection and water body purification joint effect, and simple to operate, be easy to realize.
3, the good ecosystem characterization of the ecological bank protection material of the present invention, not only guarantee the intercommunication between river bank slope air, water, soil, make insect and microorganism in soil, river course have the living environment of balance, and can improve atmospheric environment around, produce good landscape effect.
4, the ecological bank protection material of the present invention can be used as cast-type and two kinds of forms of construction work of prefabricated components formula, easy construction, applied widely.
5, the ecological bank protection material of the present invention, by the ecosystem building, can be set up effective purifying ecological food chain, realizes the renewal to bank protection structure internal contamination thing and nutritive element, guarantees that core material receives the lasting performance of nitrogen phosphoric and organic function.Invention material has long-lasting to environmental purification control.
