Description
Technical field
The present invention relates to waste material utilization and black and odorous water and eutrophic water sedimentary Treatment process fields, especially
It is related to a kind of mud repair material and its preparation and application.
Background technique
Production and sanitary wastewater are directly discharged to river or lake without processing up to standard, so that the total amount of pollutant exceeds water body
Self-purification capacity, cause water body that eutrophication is presented, or even form black and odorous water, and eutrophication water and black and odorous water are long-term
Operation will lead to a large amount of pollutant siltations in Sediments, even if cutting after the completion of dirty work and water body treating work, still have big
Measure pollutant can from Sediments sustained release.
The domestic bed mud administration way for eutrophication water and black and odorous water mostly uses the means of engineering at present, i.e.,
Sediments are all removed by engineering dredging, but can not accomplish all to remove polluted sludge, Huo Zhezhen during dredging
It is unrealistic using engineering dredging to the water body or the great water body of dredging difficulty that some siltation situations are lighter, therefore how in original
Pollutant in the effective removal Sediments in position will be a problem of urgent need to resolve during water body treating.
Summary of the invention

Deng it will be understood by those skilled in the art that the iron-bearing materials can discarding into for main oxygen-containingization iron or iron hydroxide ingredient
Lease making cross high-temperature calcination go water removal and other impurities after it is obtained.
The present invention by improve Sediments repair materials formula, can not only recycle waste reed bar, stalk,
Sawdust etc. is rich in the biomass waste resource of cellulose components, can also recycle the discarded money such as iron content rejected ore or waste
Source, and finally formed product can be used for Sediments and administer in situ, decrease or even eliminate pollutant in Sediments
Release.
Present invention simultaneously provides the preparation method of Sediments repair materials described in above-mentioned any one technical solution, packets
Include following steps:
The iron-bearing materials and the biological material are reacted at 600-950 DEG C jointly, then added with the auxiliary
Agent mixing, after solidification to obtain the final product.
It will be understood by those skilled in the art that the iron-bearing materials need pre-treatment: the Iron-ore Slag containing iron oxide is crushed, or
It is crushed after the waste residue of hydrogeneous iron oxide composition is heated；Carry out above-mentioned carburising step again after pre-treatment.
Preparation method of the present invention, the solidification are that the above-mentioned material that is stirred is carried out stable curing processing, most
End form is at a kind of powdery or granular product.Curing mode of the present invention uses conventional method in that art, herein
It does not do specifically limited.
Preparation method proposed by the invention, can simplicity the said goods are prepared, method is simple to operation, at low cost
It is honest and clean.
Present invention simultaneously provides the application method of Sediments repair materials described in above-mentioned any one technical solution, institutes
The bed mud that the targeted process object of Sediments repair materials can be high for the content of organic matter is stated, it can be to bed mud and close to bed mud circle
COD, BOD in the water body in face5, nitrogen, phosphorus play degradation.
It is provided by the invention to repair material using waste biomass material and iron slag as the Sediments of primary raw material
Material can recycle the biomass waste resource that waste reed bar, stalk, sawdust etc. are rich in cellulose components, can recycle
Using waste resources such as iron content rejected ore or wastes, finally formed product can be used for Sediments and administer in situ, reduce
It even is eliminated the release of pollutant in Sediments.
