Description
Technical field
The present invention relates to a kind of method of recycling desilting sediment and its application, more particularly to one kind utilizes desilting
The method that bed mud prepares soil-repairing agent.
Background technology
At present, with economic and society fast development, the water body such as river and lake receives different degrees of pollution
And destruction.Wherein, bed mud (also referred to as mud) is derived mainly from the silt entrained by rainwash, terrestrial organism residuum, pollution
Thing and aquatic animals and plants residuum etc., under each factor collective effect of water environment, precipitation is formed.Bed mud not only can river course is silted up,
Reduce lake to regulate and store the ability of flood, but also water body can be become to water body release nutritive salt, heavy metal and organic pollution
Endogenous pollution, feedwater ecological safety bring serious threat.
Desilting is to solve water body endogenous pollution, the effective measures of dredging channel.But, if a large amount of bed muds that desilting is produced
It is mishandling, it will huge destruction is produced to ecological environment.Desilting sediment is deposited in storage mud field usually as solid waste, this
Sample, does not only take up a large amount of places, and is also easy to produce secondary environmental pollution.Therefore, the recycling of desilting sediment has become system
The bottleneck that about desilting engineering and black and odorous water are repaired.
In addition, the water plant in the water body such as river, lake can effectively absorb the pollutant in water body in growth period.But
After its maturation, rot in water body if not gathering in and allowing, its growth period absorbs and stores the difficult degradations such as heavy metal in vivo pollution
The organic matter rich in nitrogen P elements of thing and itself synthesis all will be discharged in water body, become the endogenous pollution of water body.
And with the development of science and technology, scientific research personnel is successfully prepared for having efficiently suction using biological material anaerobic pyrolysis
The cheap charcoal of attached efficiency, its adsorption capacity are 2～3 times of activated carbon.The reparation for being applied to polluted-water was both solved
Water pollution problem, realizes the recycling of biomass waste again.And water plant is a kind of biological material of high-quality,
Desilting sediment is a kind of material rich in organic matter.This provides the possibility for solving for the problems referred to above.But have not yet to see
The technology for preferably solving the above problems.
The content of the invention
The invention aims to overcome the shortcomings of above-mentioned background technology, there is provided a kind of recycling desilting sediment
Method.
In order to realize object above, a kind of method of recycling desilting sediment that the present invention is provided, including following step
Suddenly：
(1) water plant of desilting sediment and maturation is separately dried；
(2) the dried desilting sediment and the water plant are crushed respectively；
(3) by crushing after the desilting sediment and the water plant in mass ratio 1:3～5 ratio is sufficiently mixed,
Mixture is obtained, if the water plant in material is inadequate, can be replaced with debirs such as agricultural stalk, feces of livestock and poultry；
(4) by the mixture, high temperature pyrolysis obtain charcoal under anoxic conditions；
(5) charcoal is obtained activating charcoal through acid activation, the activation charcoal is soil-repairing agent.
In such scheme, the particle diameter of the desilting sediment and the water plant after crushing is respectively less than 1mm.
In such scheme, when the organic pollution contained in the desilting sediment is exceeded, the temperature of the high temperature pyrolysis
Spend for 600～800 DEG C, time of high temperature pyrolysis pyrolysis is 1～2h, the exceeded standard of the organic pollution is《Industry
Enterprise's soil environment quality risk assessment benchmark》(HJ/T25-1999) soil benchmark (directly contact).
In such scheme, when the organic pollution contained in the desilting sediment is not exceeded, the high temperature pyrolysis
Temperature is 400～600 DEG C, and time of high temperature pyrolysis pyrolysis is 1～2h, and the exceeded standard of the organic pollution is《Work
Industry enterprise soil environment quality risk assessment benchmark》(HJ/T25-1999) soil benchmark (directly contact).
It is in such scheme, described to obtain activating concretely comprising the following steps for charcoal through acid activation by the charcoal：Will
The charcoal obtains activating charcoal with hydrochloric acid solution and water washing successively.
In such scheme, the concentration of the hydrochloric acid solution is 0.5mol/L.
When the activation charcoal is used for soil pollution to be repaired, the consumption of the activation charcoal is soil dry to be repaired
The 5～20% of weight.
When the activation charcoal is used for soil improvement, the consumption of the activation charcoal is to treat improved soil dry weight
1～10%.
The beneficial effect brought of technical scheme that the present invention is provided is：
1st, after the water plant of desilting sediment and maturation is separately dried and is crushed, mix in proportion, and in anoxic
Under the conditions of high temperature pyrolysis obtain charcoal, and charcoal as high-performance sorbing material after acid-wash activation, its adsorptivity
Can be further enhanced；
2nd, as the organic pollution that desilting sediment is carried is pyrolyzed during high temperature pyrolysis, and charcoal attachment
Heavy metal is removed during acid-wash activation, so the activation charcoal for obtaining fullys meet safe disposal desilting sediment
Requirement, and the activation charcoal can be widely used for soil pollution reparation and soil improvement；
3rd, the present invention can not only safe disposal desilting sediment, and desilting sediment and water plant can also be realized simultaneously
Recycling, also reached the purpose of soil pollution reparation and soil improvement.
Description of the drawings
Fig. 1 is the flow chart of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is described in further detail, but the embodiment should not be construed as it is right
The restriction of the present invention.
Embodiment 1：
Referring to Fig. 1, present embodiments provide a kind of method of recycling desilting sediment, first, by desilting sediment and
Ripe water plant is respectively dried, and by drying after the desilting sediment and the water plant to be crushed to particle diameter respectively little
In 1mm；Then, by crushing after the desilting sediment and the water plant in mass ratio 1:4 ratio is sufficiently mixed, and obtains
Mixture；Then, by the mixture 450 DEG C under anoxic conditions (organic pollution contained in desilting sediment is not exceeded) or
700 DEG C (organic pollution contained in desilting sediment is exceeded) pyrolysis 1h obtains charcoal；Finally, the charcoal is used successively
The hydrochloric acid solution and water washing of 0.5mol/L obtains activating charcoal, and the activation charcoal is soil-repairing agent.
Above-mentioned soil-repairing agent does not detect the heavy metal or organic pollution of solubility.The soil-repairing agent for obtaining is used for
The reparation of certain heavy metal cadmium and Pyrene contaminated soil, consumption are the 10% of soil dry weight to be repaired.Above two
The soil-repairing agent that pyrolysis temperature is obtained --- soil-repairing agent (450 DEG C) and soil-repairing agent (700 DEG C) repairing polluted soil
After one month, biologically effective state cadmium and pyrene in soil is determined.It was found that biologically effective state cadmium content reduces more than 76%, biology
