Embodiment
Below in conjunction with embodiment, the present invention is described in detail.
The present invention uses changing food waste to make the material compositions of organic fertilizer, be made up of following raw material according to mass percent: changing food waste powder 20% ~ 95%, straw powder 3.5% ~ 50%, humic acid powder 1% ~ 30%, lactobacillus powder 0.5% ~ 1.5%, above-mentioned each constituent mass per-cent sum is 100%; Wherein, in humic acid powder, organic content is not less than 50%; The fineness of changing food waste powder, straw powder, humic acid powder, lactobacillus powder is 20 ~ 70 orders.
Use changing food waste to make the method for organic fertilizer, comprise the following steps:
Step 1: the changing food waste reclaimed from machine-operated brick kitchen range, restaurant, hotel etc. is poured into impurity elimination sorting in vibratory screening apparatus, after sifting out the foreign material such as the plastic skin in changing food waste, bottle, wooden chopsticks, enter again in centrifugal type solid/liquid separator and carry out solid-liquid separation, waste water waste oil is thrown away, oily(waste)water is poured in water-and-oil separator and carry out oily water separation, waste water after separation is used for the water source of brick sintering plant or boiler smoke abatement dedusting, make oil fuel after adding used oil in waste oil, residual moisture content is not more than the solid-state changing food waste of 80%;
Step 2: solid-state changing food waste step 1 obtained is put into kiln after pouring into and carrying out pulverization process in pulverizer and carried out drying, drying utilize boiler heat or power plant, cement mill, brick sintering plant waste heat as thermal source, the carrier bar rotating adjustable speed carries out drying, dry temperature is 60 DEG C ~ 110 DEG C, germ in changing food waste can be killed, do not destroy nutrition again, dried water content is not more than 3%, obtains dry changing food waste powder;
Step 3: add straw powder, humic acid powder, lactobacillus powder according to a certain percentage in the changing food waste powder of the drying obtained to step 2, wherein, changing food waste powder 20% ~ 95%, straw powder 3.5% ~ 50%, humic acid powder 1% ~ 30%, lactobacillus powder 0.5% ~ 1.5%, above-mentioned each constituent mass per-cent sum is 100%, wherein, in humic acid powder, organic content is not less than 50%, the fineness of changing food waste powder, straw powder, humic acid powder, lactobacillus powder is 20 ~ 70 orders, then stirs, to obtain final product.
During use, according to land fertility or farm crop to organic requirement, in the native ditch organic fertilizer that a certain amount of changing food waste makes is sprinkled into dark 13 ~ 18cm, holding from crop root part 28 ~ 33cm boot successfully, then earthing compacting.What be buried in the earth absorbs moisture content with the organic fertilizer that changing food waste makes, and under the effect of Soil Microorganism, humic acids and milk-acid bacteria, starts slaking of fermenting, through fermentation slaking after a while, changes into the fertilizer that can be absorbed by farm crop.Milk-acid bacteria can carbohydrate in fermented garbage from kitchen powder, changes into the multiple nutrition that can be absorbed by farm crop; Humic acids with the metal ion clutch in water, can be conducive to nutritive element and transmits to farm crop, promotes crop growth; Straw powder is the general name after farm crop cauline leaf (fringe) part drying is pulverized, and returns crop stocks to the field and can improve farmland ecological environment, plays water conservation and breathes freely, suppress weed growth, increase the effects such as fertilizer efficiency to soil.
The invention has the beneficial effects as follows: be main raw material with changing food waste, add straw powder and some compatible batching making organic fertilizer containing a large amount of microorganism, the changing food waste after process is made to form solid fertilizer, without the need to building changing food waste fermenting container and purchasing the load carrier for vehicles of roping natural pond liquid, natural pond slag.Produce and do not limit by temperature and season, can produce throughout the year, and be easy to preservation, transport, fertilising simply.The changing food waste composition of spontaneous fermentation slaking in soil, the fertilizer of formation can be absorbed by farm crop, and can prevent from transition from using chemical fertilizer causing soil compaction phenomenon.Both solved the problem of " sewer oil ", " swill pig ", the secondary pollution preventing again changing food waste from causing environment, has less investment, instant effect, and land occupation area is little, turns harm into good, and turns waste into wealth, and realizes the object of resource utilization kitchen rubbish.
