Description
Technical field
Saline-alkali soil conditioner is prepared the invention belongs to reclamation of salinep-alkali soil technical field, more particularly to a kind of use cinder
Method.
Background technology
At present, China produces cinder per year more than hundred million tons, and, more than 30,000,000 tons, huge solid waste resource yield is only for municipal sludge
By landfill or orderly treatment of banking up, the environment dirt of underground water, air to effective solution of solid waste, cannot be far ultimately caused
Dye.There is the hm2 of all kinds of salt-soda soils about 100,000,000 in China, wherein the modern hm2 of (activity) wetland with saline-alkaline about 0.37 hundred million, remaining saline-alkali soil ground
0.45 hundred million hm2, and the hm2 of potential wetland with saline-alkaline 0.17 hundred million, 80% salt-soda soil also having in China are not yet developed.
How research utilizes cinder, the recycling of sludge, for improveing saline and alkaline soil, with good economic results in society.Tool
Body is：Improve the saline and alkaline proterties of Soils In The Region, improve plant survival rate and crop yield；Cinder, the landfill of sludge is saved to bank up expense
With；Reduce water body, atmosphere pollution, Revegetation of Eco-environment.Using cinder and sludge with improvement salinization of soil soil is applied, can reach " with
Useless controlling is moved back ", " useless moving back mutually is controlled ", it is the special efficacy of double profits to become double evils, can preferably realize that environmental benefit is mutually tied with economic benefit
Close, and the social and economic comprehensive significance with environment.
The content of the invention
Originally the purpose for being invention is to provide a kind of method that use cinder prepares saline-alkali soil conditioner, above-mentioned to solve
Problem.
The invention provides a kind of method that use cinder prepares saline-alkali soil conditioner, including：
By gasifier slag, municipal sludge, mushroom residue, 4 are compared according to weight:5:1 is mixed and stirred for uniformly；
Standing for fermentation is carried out after mixture stockpile is high, after temperature is higher than 45 DEG C, turning was carried out every 3 days, temperature is less than
After 35 DEG C, turning treatment is not done to mixed material, using spontaneous fermentation；
After mixed material ferments 45 days, control the water content of mixed material to be less than or equal to 40%, obtain final product the reclamation of salinep-alkali soil
Agent.
Further, the method also includes sieving gasifier slag, chooses gasification of the particle diameter less than or equal to below 2cm
Slag is used as the raw material for preparing saline-alkali soil modifying agent.
Further, municipal sludge is municipal sewage plant sludge, and water content is less than or equal to 80%, and mushroom residue is cultivating mushrooms
Waste material afterwards, water content is less than or equal to 50%.
Further, the method also includes carrying out metering packing to the saline-alkali soil modifying agent for obtaining.
Compared with prior art, the beneficial effects of the invention are as follows：The modifying agent preparation method is simple, can be provided waste
Source, environmental pollution can be largely mitigated using the modifying agent, improve salt affected soil physicochemical character, improve saline-alkali soil
Suitable kind, workability of soil, there is good demonstration to promote meaning to dispose and recover surface vegetation ecological environment to solid waste pollution treatment.
Specific embodiment
The present invention is described in further detail below by specific embodiment.
Present embodiments provide a kind of method that use cinder prepares saline-alkali soil conditioner, gasifier slag after screening,
Once particle diameter is municipal sewage plant sludge, aqueous≤80%, mushroom residue as modifying agent raw material, municipal sludge is prepared to choose 2cm
It is waste material after cultivating mushrooms, aqueous≤50%.Modifying agent preparation method is：Choose gasifier slag (≤2cm), municipal sludge, mushroom
Mushroom slag, 4 are compared according to weight:5:1, it is delivered to biaxial rneader using belt conveyor and mixed material is mixed, stirs
Uniformly, to fermentation process workshop, high to mixture stockpile 1.5 meters, 2 meters of bottom width is long 100 meters, carries out standing for fermentation, treats temperature for transport
After degree is higher than 45 DEG C, turning was carried out using turning machine every 3 days, after temperature is less than 35 DEG C, turning is not done to mixture stockpile body
Treatment, using spontaneous fermentation.After 45 days fermentation phases of mixed material terminate, mixed material moisture ＜ 40% is transported to semi-finished vehicles
Between, stored for future use.Semi-finished product are carried out with metering packing, as saline-alkali soil modifying agent finished product.
The present embodiment, by the fermentation of banking up of 45 days, is prepared a kind of using cinder, municipal sludge, the compound proportioning of mushroom residue
Saline-alkali soil conditioner.Modifying agent composition and part by weight are：Cinder 40%, municipal sludge 50%, mushroom residue 10%, the stove
Slag is gasifier slag, and sludge is municipal administration domestic sludge.The modifying agent prepared by the method can comprehensively improve the organic of salt-soda soil
Matter, N P and K and micronutrient and the quality in improvement salt-soda soil, can improve the physicochemical character and regulation saline-alkali soil in salt-soda soil
Ratio, adjust saline-alkali soil value and desalination drop alkali simultaneously reduce some harmful elements, reach it is economical and practical, rapidly and efficiently, benefit
Comprehensive effect, realizes the unification of social benefit, environmental ecological benefit and economic benefit.
Embodiment 1
Saline-alkali soil conditioner preparing raw material is originated：
Slag：It is China Shenhua Coal to Liquid and Chemical Co., Ltd., Texaco gasifier slags.
