Description
Technical field
The present invention relates to garbage loading embeading processing technology fields, and in particular to it is a kind of without soil spraying covering material additive and
Preparation method.
Background technology
While economy grows continuously and fast, living standard improves rapidly, urbanization process is constantly accelerated, the life of China city
The yield of rubbish living is also growing day by day.Contained in rubbish and generation harmful components can cause air, soil, water body
Pollution, not only seriously affects city environmental quality, but also directly threaten health, becomes one of social effects of pollution.Therefore, city
House refuse is treated as great environmental problem urgently to be resolved hurrily.Municipal refuse landfill is the most basic disposition side of municipal refuse
Method.Usually metropolitan wastes sorting is recycled, after unrenewable drying garbage is filled, utilize hollow area fill city rubbish
Rubbish, in China, the vast majority of soot are also covered using clay compaction, but are carrying out landfill yard using clay compaction
When covering, there is occupy storage capacity, price are high, be unfavorable for garbage degradation and the collection of Leachate site the problems such as.
Therefore the new approaches that new covering material is the current garbage problem for solving getting worse are made.
Strong and convenient for plant growth the ability of erosion resistibility, phosphorus tailing need to be met by being applied to the cover soil material of rubbish covering
It is a kind of lean property tailing, phosphonium ion can not be discharged for plant absorption, be usually to be given up not having in the use of cover soil material,
But treated phosphorus tailing has certain viscosity, can be used as cohesive material, simultaneously because containing in phosphorus tailing
A large amount of P elements can not only provide required P elements, because sticky, antiscour if can fully utilize to plant
Ability can also enhance, if in cover soil material, it is clear that can administer field to garbage loading embeading and provide a new approaches.
Invention content
The invention is intended to provide a kind of additive without soil spraying covering material, solves the prior art and do not answer phosphorus tailing
The problem of improvement field being filled used in rubbish.
In this programme includes following raw material：Reverse flotation phosphorus tailing, fertile soil and cement, the parts by weight of each raw material
For 20 ~ 30 parts of 50 ~ 60 parts of reverse flotation phosphorus tailing, 20 ~ 30 parts of fertile soil and cement.
Beneficial effects of the present invention：1, the additive of the invention without native sprayed on material can largely utilize reverse flotation phosphorus tail
Mine, the ratio of reverse flotation phosphorus tailing can largely, integrally consume the industry of this type of reverse flotation phosphorus tailing between 50 ~ 60%
Waste solids reduce and discharge consumed floor space, adequately utilize the resource of P elements, turn waste into wealth, increase phosphorus ore enterprise
Additional income, reduce without soil spraying covering material manufacturing cost；2, saprophytic bacteria can be to reverse flotation phosphorus tailing in fertile soil
P elements and alkali metal ion are decomposed and are activated, and are released the absorbent available phosphorus of a large amount of plants, so that it is largely enriched with, together
When degrade alkali metal ion, the alkalinity of soil is reduced, in favor of the reparation of rubbish soil and the growth of later stage plant.3, cement
Used primarily as bonding agent, used in spraying covering material without soil, the form for stablizing covering material avoids
Rubbish is lost in the loss of water and soil, and then influences the reparation to rubbish soil and degradation effect.The present invention's sprays without soil
The additive of covering material can not only largely utilize reverse flotation phosphorus tailing, while utilize the effect of fertile soil and cement, viscosity
Stronger, stability higher, erosion resistibility is enough, while available phosphorus being made to be enriched with, and is conducive to the absorption of plant, and reduces additive
Alkalinity, it is ensured that the using effect of covering material.
It is further preferred that the parts by weight of each raw material are 60 parts of reverse flotation phosphorus tailing, 20 parts of fertile soil and cement
20 parts.
Further preferred, the parts by weight of each raw material are 50 parts of reverse flotation phosphorus tailing, 20 parts of fertile soil and water
30 parts of mud.
Another step is preferred, and the parts by weight of each raw material are 50 parts of reverse flotation phosphorus tailing, 30 parts of fertile soil and cement
20 parts.
Aforementioned proportion is the best proportion of the present invention, carries out washing away rainwater experiment to sample after being respectively configured and examines basicity
Experiment, for formula of the invention in the case where being washed away under water is the rainfall intensity of 1320mm/h, the stable form of test sample resists rain
The flushing time of water is 130 ~ 150min, and ability to resist splash erosion is strong.
Further, the fertile soil is fallen leaves by paper pulp mud, Panasonic and garden mould is according to 1:1:4 configure.Garden mould is again
Claim vegetable garden soil, rural area soil, is through farming and to cultivate the soil of flowers and trees, vegetables；The fertile soil of the recipe configuration, can be by acidity
The alkaline matter in reverse flotation phosphorus tailing is gradually neutralized, while conducive to the degradation of rubbish soil, reduces and sprays covering material without soil
The basicity of material.
Further, the cement is portland cement.Very fast with condensation hardening, early strength is higher, the heat of hydration compared with
Greatly, frost resistance is preferable, and drying shrinkage is smaller, and corrosion resistance is poor, and the poor feature of heat resistance is taken with reverse flotation phosphorus tailing and fertile soil
With use, degradation property is more excellent.
Preparation method without soil spraying covering material additive, will use the rubble for being ground into a diameter of 5 ~ 20cm, be put
1.5 ~ 2h of calcining at 900 ~ 1000 DEG C is set, it is 10 ~ 20 mesh particles to be ground into grain size again, mixed with fertile soil and cement in proportion
It closes.
The preparation method of the present invention is simple, and exploitativeness is strong, is calcined after reverse flotation phosphorus tailing is crushed, obtains CaO
And MgO, increase viscosity, then with fertile soil and cement mixing, you can obtain without soil spraying covering material additive, storeroom phase
Mutually cooperation, makes the available phosphorus of additive largely discharge, and is conducive to the growth of plant, and the sprayed on material made using the additive can be prevented
Water, fire prevention, deodorization and fly eradication can effectively facilitate landfill area's vegetation growth, while resisting rainwater and taking out brush, relative to traditional landfill
For material, 20% is improved to landfill yard environment restoration degree.
