Abstract
The invention discloses a soil repairing agent by taking garden waste as a main raw material. The soil repairing agent comprises the following raw materials in parts by weight: 65-68 parts of garden waste, 4-6 parts of limestone powder, 3-4 parts of malt roots, 9-11 parts of bean curd residues, 2.6-2.8 parts of chitosan oligosaccharide, 2-3 parts of potassium sulfate, 12-14 parts of rice chaff ash, 2-3 parts of sodium bicarbonate, 34-36 parts of polluted pen manure, 6-7 parts of papermaking black liquor, 2.2-2.4 parts of a nitric acid solution with concentration being 10%, 6-8 parts of alum slurry, and a proper amount of water. The soil repairing agent employs the waste in garden as the main raw material, uses a lot of cellulose, lignin and organic nutrients in the waste, and combines addition of the fermentation products such as bean curd residues, and potassium sulfate and sodium bicarbonate, so that soil nutrients supplementing is realized, the soil aggregate structure and microflora in the shallow soil layers can be greatly improved, cost of the waste is low, so that the repairing agent has high usage value.
Description
Technical field
The present invention relates to technical field of soil remediation, particularly relate to the soil-repairing agent that a kind of garden waste is primary raw material.
Background technology
Soil improvement is the bad quality for soil and structure, takes corresponding measure to improve soil property, increases soil fertility, and soil improvement renovation agent is a kind of important application of soil improvement.But seen soil remediation modifying agent has many defects in the market: one is to use raw material with synthetic macromolecular compound, and it is not easily decomposed and extended residual in soil, has potential safety hazard;Two is function singleness, for variety classes soil, such as acid and basic soil, heavy metal pollution degree, nutrient are deficient etc. without effectively for, cause improveing remediation efficiency low, even play retroaction;Three is that the cycle of improving the soil is long, and relatively costly, it is impossible to large-scale application.For problem above, low cost, high specific aim and environmentally friendly soil remediation modifying agent become soil improvement aspect prior development direction.
Pig dung and urine is as a kind of renewable biological source wide, with low cost of originating, the nutrients such as abundant organic matter and N P and K are contained because of it, use as the raw material of soil improvement reparation and there is great potential, and owing to economization cultivation needs, during pig is fed, feedstuff contains a large amount of additive, cause heavy metals exceeding standard, indirect pollution Excreta.And by pickling and ultrasonication, the metallic compound of indissoluble state in Pig dung and urine can be made to form soluble metal ion, and utilize acoustic cavitation effect to make the pulverizing of pig manure granule, cell wall crack, the heavy metal release of order absorption and parcel is out, the two is used in combination and reaches to purify purpose, makes this cheap raw material of pollution Pig dung and urine apply and is possibly realized in the preparation of soil improvement renovation agent.
Alumen slurry is Alumina by-product when " water seaoning " produces Alumen, through dried gained white powdery solids, its main component is silicon oxide, aluminium oxide and the silicate mineral of water composition, and containing macroelement and various trace elements such as abundant Ca, Mg, Fe, K, S, P, because it has the features such as granule is thin, specific surface area is big, absorption affinity is strong, there is in terms of soil improvement good application prospect.
The above being conjointly employed in the exploitation of soil remediation modifying agent, is simply easily achieved, the development for soil improvement renovation agent opens new way.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of garden waste is the soil-repairing agent of primary raw material.
The present invention is achieved by the following technical solutions:
A kind of garden waste is the soil-repairing agent of primary raw material, is prepared by the raw materials in: garden waste 65-68, limestone powder 4-6, root of Cornu Cervi Pantotrichum 3-4, Glycine max (L.) Merr. 9-11, oligo-chitosan 2.6-2.8, potassium sulfate 2-3, rice chaff ash 12-14, sodium bicarbonate 2-3, pollution Pig dung and urine 34-36, black liquid 6-7,10% salpeter solution 2.2-2.4, Alumen slurry 6-8, water are appropriate.
Described garden waste is specifically comprising the following steps that of the soil-repairing agent preparation method of primary raw material
(1) root of Cornu Cervi Pantotrichum, rice chaff ash, Glycine max (L.) Merr. are mixed and added into the water of gross weight 1.5-2 times, and after mixing, in retting fermentation 3-4 week, obtain fermentation residue and fermentation liquid be standby after fermentation material crushes expression separation;
(2) put into after black liquid being dried in calcining furnace, calcine 80-90 minute at 430-450 DEG C, it is mixed and added into gross weight 3-4 times quality water with pollution Pig dung and urine after taking-up, 10% salpeter solution is added after stirring evenly, and compound is carried out supersound process, supersonic frequency is 40kHz, compound is pressed after ultrasonic 120-140 minute 60-80 rev/min and stirs 3 hours, stand 60-90 minute afterwards, after removing upper solution, lower floor's drying materials is pulverized stand-by;
(3) garden waste is pulverized, it is placed in high temperature furnace and is heated to 480-500 DEG C under conditions of isolation air, obtain biomass charcoal powder, and with step 1 gained fermentation residue, step 2 gained material, limestone powder, oligo-chitosan mixing granulation, obtain spheroidal particle standby;
(4) Alumen starch comminution is crossed the most afterwards 100-120 mesh sieve, and mix homogeneously by solid-liquid mass ratio 1:4 with 1mol/L sodium hydroxide solution, be again heated to 74-76 DEG C, filter after being incubated 60-80 minute and take out Alumen slurry, clean to neutral with water, dry for standby;
(5) step 1 gained fermentation liquid is mixed with step 4 gained modification Alumen slurry, potassium sulfate, sodium bicarbonate and other residual componentss, again step 3 gained granule is placed in the roller machine with shower nozzle of the top, during rolling granule, granule is uniformly sprayed by mixed fermentation liquid through shower nozzle, the coated particle oven drying at low temperature at 40-45 DEG C that finally will obtain.
The using method of the present invention is for being embedded at upper soll layer 10-15cm by renovation agent after being turned over by contaminated soil, and every mu of soil uses 80-100kg renovation agent.
The invention have the advantage that
The mixing scrubbing of Pig dung and urine and black liquid uses and soil organic level is greatly improved, and erodable Alumen slurry surface after thermokalite modification Alumen slurry, it is made to become rough porous, surface texture loosens, and specific surface area improves, and strengthens the lattice fixation of its heavy metal ion, serve not only as improvement reparation grain skeleton and there is good stability, and the residuals such as heavy metal-passivated, chemical medicine can be adsorbed, alkaline modification Alumen slurry mixes with the Pig dung and urine of acidifying, also ensure that stablizing of P in soil H-number.The garbage that the soil-repairing agent of the present invention produces in being produced in gardens is as primary raw material, utilize a large amount of celluloses, lignin and the organic nutrient wherein contained, coordinate tunning and potassium sulfate, the interpolations of sodium bicarbonate such as Glycine max (L.) Merr., i.e. achieve supplementing of soil nutrient, there is bigger improvement in microbiologic population to soil aggregate and shallow soil layer again, dead meal is with low cost simultaneously, makes renovation agent have higher use value.
