Abstract
A mixed organic-inorganic fertilizer contains organic fertilizer (30-90 Wt.%) including mud and/or seaweed dregs and inorganic fertilizer (10-50 Wt.%) including N (2-8%), P2O5 (2-8%) and K2O (2-10%), and serves to update and collect organic matter in soil, promote the multiplication of microbe in soil and increase fertility of nutrients in soil.
Description
The present invention relates to a kind of serves as that main fertilizer raw material is equipped with the mixed fertilizer that inorganic fertilizer makes and the production method of this mixed fertilizer with algae-residue, mud.
Chinese patent application CN1097409A (application number 94105987.1) discloses a kind of " composite organic bacterial fertilizer made from algae dregs and method for making ", this compound bacterial fertilizer contains algae-residue, peat, slag, cement mill kiln ash and fixed nitrogen bacterial classification, wherein the content of algae-residue is 60-80%, peat 15-35%, slag 2-3%, cement flue Dust 1-2%, fixed nitrogen bacterial classification 0.5-1.5%, and its preparation method adopts following steps: the collection of algae; The dehydration of algae; The pulverizing of algal biscuit and hydrolysis treatment thereof; The preparation and the interpolation of peat end, cement mill kiln ash mixture; Add the fixed nitrogen bacterial classification; Humidity, ventilation and packing.Chinese patent application CN1097724 (application number 94105972) discloses a kind of " method of utilizing municipal sludge, ight soil to produce highly efficient granular organic fertilizer ", handling the mud, the ight soil that produce with the urban domestic wastewater is main raw material, through production technique such as slaking, dehydration, pulverizing, batching, granulation, oven dry, screening, packings, make organic fertilizer.
Purpose of the present invention aims to provide a kind of waste that utilizes---and algae-residue that water treatment produces and mud that is produced from the municipal sewage plant are that main fertilizer raw material is equipped with the various crops special use mixed fertilizers that inorganic fertilizer makes and the preparation method of this mixed fertilizer.
Fertilizer made from algae residue and sludge of the present invention mainly is grouped into (weight percent) by following one-tenth: fertilizer 30-90%, inorganic fertilizer 10-50%, described fertilizer is one or both the mixing in mud, the algae-residue, contains effective N2-8%, P in the described inorganic fertilizer
2O
52-8%, K
2O2-10%.
The preparation method of organic-inorganic mixed fertilizer of the present invention comprises following steps:
One, to water ratio 70-80%, further dewater to water ratio 5-30% again by drying through mechanical dehydration for algae-residue;
Two, mud is dried to water ratio 5-30%;
Three, above-mentioned algae-residue is mixed with mud, or use algae-residue or mud separately, handle in the normal temperature bottom fermentation;
Four, add that inorganic fertilizer is mixed, granulation, drying, cooling, pack, dispatch from the factory by prescription.
Algae-residue of the present invention is mainly the phycophyta that produces in the water treatment procedure, its water content is generally more than 98%, mud is mainly the active sludge that produces in the urban sewage purification, the water content of algae-residue and mud is all higher, the algae-residue processed was divided into for two steps, add earlier flocculation agent through mechanical dehydration to water ratio 70-80%, the drying method is not destroyed biological activity and is dried to water ratio 5-30% again, the side also carries out fermentative processing, the bacterial classification of fermentation is gibberella or actinomycetes, fermentation can be carried out at normal temperatures, and fermentation time was generally 2-7 days, did not also add bacterial classification during fermentation, because all contain natural bacterial classification in algae-residue and the mud, can carry out from fermentation, but fermentation time mixes by formula rate after algae-residue and mud also can ferment separately more generally at 7-10 days, is dried between the water ratio 5-30%.Algae-residue that mixes and mud add inorganic fertilizer by prescription, make add effective N, P in the inorganic fertilizer
2O
5, K
2O content reaches the prescription requirement, and can adjust prescription according to soil and crop species, adds a small amount of effectively Fe, Mn, B, Cu, trace elements such as Zn, Mo.Fertilizer of the present invention is a mud, the mixing of one or both in the algae-residue, and inorganic fertilizer can adopt general inorganic fertilizer, as urea, ammonium nitrate, vitriolate of tartar, phosphate fertilizer or the like.
Fertilizer made from algae residue and sludge of the present invention contains organic and nitrogen, phosphorus, potassium and various trace element simultaneously, can influence the renewal and the accumulation of the soil organism in being manured into soil, produce priming effect, promote the breeding of microorganism in the soil, help the effectuation of nutrient in the soil.The refuse that the main raw material algae-residue of this mixed fertilizer produces during for water treatment, mud all is the refuse that produces in municipal water purification and the sewage disposal, and the present invention is turned waste into wealth, and has both obtained the mixed fertilizer of high efficiency, low cost, administered environmental pollution again, kept ecological balance better.
Embodiment:
1, the fresh algae-residue of water intaking factory, water ratio 98% carries out centrifugal compression earlier and dewaters to water ratio 76%, is dried to water ratio 20% again, get the municipal wastewater mud that sewage work produces, water ratio is 80%, is dried to water ratio 10%, gets the algae-residue 10kg of above-mentioned processing, mud 52.5kg, mix, add gibberella liquid 200g, in normal temperature bottom fermentation three days, (perhaps get and stacked 7 days left and right sides algae-residue mud, no longer through fermentative processing), be dried to water ratio 5-10%, add ammonium nitrate 7kg again, general calcium 6.6kg, vitriolate of tartar 12kg, composite fertilizer 11.84kg, making effective N wherein is 3-5%, P
2O
53-5%, K
2O 6-10%, above-mentioned mixing of materials is even, and the granulation cooling packing gets final product.This kind fertilizer is mainly used in the land for growing field crops cash crop.
2, get mud, water ratio is 80%, to water ratio 10%, gets mud 70kg through mechanical drying, adds urea 8.7kg again, vitriolate of tartar 4.8kg, and coarse whiting 15kg, N, P, K composite fertilizer 4.5Kg are dried to water ratio 5-12% and make wherein, and effectively N is 3-5%, P
2O
53-5%, K
2O 1.5-3%, above-mentioned mixing of materials is even, and packing is dispatched from the factory.The main land for growing field crops of this kind fertilizer food crop.
