Abstract
The invention discloses water-retaining organic fertilizer. The water-retaining organic fertilizer is prepared from the following materials in percentage by weight: 40-60% of municipal sludge, 30-35% of a swelling agent, 5-10% of flue gas desulphurization gypsum, 2-7% of calcium nitrate, 2-7% of diammonium phosphate and 1% of a zymophyte agent. The invention also discloses a preparation method of the water-retaining organic fertilizer. The water-retaining organic fertilizer has the beneficial effects that municipal sludge is mixed with the swelling agent and flue gas desulphurization gypsum and aerobic fermentation is carried out, so that the water-retaining organic fertilizer is obtained, the void content and fermentation rate of sludge are increased while both total content of calcium and organic matter content are increased; and the added flue gas desulphurization gypsum can be used for improving the water solubility and microbial activity of the water-retaining organic fertilizer, the municipal sludge, the swelling agent and the flue gas desulphurization gypsum in the used main materials are low in cost and easy to obtain and can be recycled, waste materials are changed into things of value, and the preparation technology is simple.
Description
Technical field
The present invention relates to municipal wastewater process reclaiming organic waste and utilize field, be specifically related to a kind of water retention type organic fertilizer material and preparation method thereof.
Background technology
The process of municipal sludge is a global difficult problem, the mishandling secondary pollution easily causing the wasting of resources and environment.From composition angle analysis, mud is a kind of complicated component, unstable Biological resources, but the nutritive substance be rich in needed for plant, organic content is generally about 40%, and N P and K macroelement and micronutrient levels are also quite abundant, very valuable manure resources.In mud, the content of polyacrylamide is between 5-10% simultaneously, and having stronger water-retentivity, is the good material producing water-holding agent fertilizer.If therefore municipal sludge, through reasonably disposing and processing, can be recycled usually, being administered on farmland or forest and flowers, both can improving soil quality, and can fertility be improved again.Be 60% in state's mud agricultural use rates such as English, U.S., method, Holland, embody the validity feature that sludge circulation utilizes just, but not only a kind of waste.
NORTHWEST CHINA area drought and water shortage, ecological environment frailty, desertification of land is serious.In desert edge region, be caught in a sand storm, pasture, good farmland, village are ruined or are buried; The facilities such as railway, highway, reservoir, feed ditch are all threatened and are destroyed, therefore Ecological Afforestation and restoration of the ecosystem task heavy, significant.Due to this regional drought lack of water, soil depletion and basicity and pH high, the surviving rate of forest flower is extremely low.If municipal sludge can be applied to restoration of the ecosystem field, the Northwest, not only can save the processing costs of waste, also can improve region and even national ecotope, increase farmers' income, to regional circular economy development, improve the ecological environment, ensure that ecological safety is all significant.
Forest and flowers huge by fertile demand, but because of the reason such as the inadequate and transportation cost of originating is more expensive, amount of application reduces gradually.Municipal sludge not only containing abundant nutrient, and has stronger water-retentivity, and water-holding power can reach more than 200%, and is valuable forest and the fertile source of flowers, administers significant to the restoration of the ecosystem of Northwest arid district and desertification and desertification.
Summary of the invention
Object of the present invention is exactly for above-mentioned defect of the prior art, provides the water retention type organic fertilizer material of the ecological purposes in a kind of arid area utilizing municipal sludge to prepare.
To achieve these goals, technical scheme provided by the invention is: a kind of water retention type organic fertilizer material, prepared by the following material according to weight percent meter: municipal sludge 40-60% (gives money as a gift heavily, water content about 10%), leavening agent 30-35%, desulfurated plaster 5-10%, nitrocalcite 2-7%, diammonium phosphate 2-7%, fermenting agent 1%.
The harmful substance contents, particularly heavy metal content such as all raw material heavy metals need meet woods content limit standard, preferably meet agricultural content limit standard.
Second object of the present invention there is provided the preparation method of above-mentioned a kind of water retention type organic fertilizer material, municipal sludge is taken according to above-mentioned proportioning, leavening agent, desulfurated plaster, nitrocalcite, diammonium phosphate and fermenting agent, by desulfurated plaster natural air drying, make its moisture content≤10%, then 0.5mm sieve was pulverized, oven drying method is adopted to measure water content the municipal sludge that appropriate resourcesization utilizes again, conversion dry weight after proportionally with leavening agent, desulfurated plaster and fermenting agent mix, after adjustment water content to 50-60%, pile bar heap in echelon and carry out aerobic fermentation, every turning in 3-5 days 1 time, trapezoidal bar heap is about bottom width 2m, top width about 1m, high 1.5m, when heap temperature continous-stable more than 3 days, and close to after free air temperature, the material after heap corruption is spread out, air-dry, make its moisture content≤10%, ferment rear air-dry or dry, after composite nitrocalcite and diammonium phosphate, made nitrocalcite account for the nitrocalcite 2-7% of total mass, diammonium phosphate accounts for the 2-7% of total mass, and pulverize, prepare water retention type organic fertilizer material, particle diameter≤5mm finally by the granulation process extruded or transfer shares.
Further, the preparation method of above-mentioned a kind of water retention type organic fertilizer material, described desulfurated plaster is the byproduct of means of flue gas desulfurization of power plant, calcium contents >=30%.
Further, the preparation method of above-mentioned a kind of water retention type organic fertilizer material, described leavening agent is the byproduct or the maize straw that utilize corn cob to produce Xylitol, organic content >=75%.
Further, the preparation method of above-mentioned a kind of water retention type organic fertilizer material, in described diammonium phosphate, phosphorus content (P
2o
5)>=46%, nitrogen content>=18%; In nitrocalcite, nitrogen content>=15.5%.Nitrocalcite and diammonium phosphate nutrient content should meet corresponding fertilizer standard.
Effect test:
Minqin County of Gansu is slight saline and alkaline excessive area fix the sand this fertilizer on probation on forest, if contrast (0), 4,8,15 tons/hm2, after 1 Growing season, soil pH comparatively contrasts and can reduce 0.09-0.14 unit, and farming sodium ion and magnesium ion content comparatively contrast and reduce 9-12% and 6-12% respectively.The surviving rate of sapling is 86.7%, and comparatively contrast improves 45-70%, and footpath slightly comparatively contrasts increases 8-16%, and height comparatively contrasts increases 9-19%.
Beneficial effect of the present invention is: municipal sludge and raising agent and desulfurated plaster are mixed into aerobe fermentation of acting charitably by the present invention, prepare water retention type organic fertilizer material, the total content of calcium is not only increased while the voidage that improve mud and fermentation rate, make it >=3%, and add organic content, make its organic content be up to state standards require content >=45%, abundant calcium ion can with sodium ion exchange in soil, reduce the saline and alkaline of soil, improve Soil structure, abundant organic mass-energy promotes soil organic matter content and soil fertility, increase microorganism active, promote the generation of soil agreegate, the desulfurated plaster added, improves the water-soluble of desulfurated plaster and microorganism active, and in main raw used, municipal sludge, leavening agent and desulfurated plaster, with low cost, easily obtain, cycling and reutilization, turn waste into wealth, preparation technology is simple.
