Abstract
The invention discloses a sludge bio-organic fertilizer. The sludge bio-organic fertilizer is characterized by being mainly prepared from the following substances in percentage by weight: 50-60% of sludge, 15-20% of humic acid, 15-20% of grass-wood charcoal and 10% of binder, wherein the sludge is raw sludge which is subjected to composting fermentation. A preparation method of the sludge bio-organic fertilizer comprises the steps of carrying out composting fermentation, granulating, drying, cooling, screening, metering, packaging and warehousing. According to the sludge bio-organic fertilizer and the preparation method thereof, the raw sludge is adopted as a raw material and is subjected to microbial fermentation, organic substances are subjected to biodegradation so as to form stable humus, and thus, the pollution to environment caused by the fertilizer can be reduced; and meanwhile, the organic fertilizer with good fertilizer effect is produced, and the waste is changed into the valuable.
Description
Technical field
The invention belongs to technical field of fertilizers, especially a kind of sludge organism fertilizer, also relates to its preparation method.
Background technology
Water resources is to guarantee the most basic condition of human survival, thereby water conservation, prevents the pollution of sewage to environment, is that the mankind benefit substantial responsibility throughout the ages.In order to improve the serious present situation of China's water resource pollution, from the enforcement period of the ninth five-year plan waste water control problem, fully to be paid attention to, city sewage treatment works project development is very fast.Yet for a large amount of mud that produce thereupon, China adopts landfill disposal mostly at present, deals with improperly still and can cause the secondary pollution to environment.The processing of mud is disposed and utilized has more and more become the large problem that solution is badly in need of in China.Mud is the sedimentable matter producing in sewage treatment process, it comprises the solid particulates such as silt particle in sewage, fiber, plant and animal residues and the floss condensing thereof, the integrated solid materials such as the metallic element of various colloids, organism and absorption, microorganism, germ, worm's ovum, weed seed.Because major ingredient in the mud of municipal sewage plant is organism, thereby itself be exactly good agricultural fertilizer raw material, can fully utilize, by its changing waste into valuable.This engineering adopts the innoxious farm technology of municipal sludge; municipal sludge is mixed with substance (its composition is mainly bacterial classification, flyash, grass meal and N, P, K nutrient substance etc.); make the biological organic fertilizer, the organic and inorganic compound granular fertilizer that can be used for seed sower and sow; this compound fertilizer product belongs to efficient biologic-organic fertilizer and organic-inorganic slow-release fertilizer; to improving crop yield, soil protection has positive effect, is the agricultural fertilizer kind with large development potentiality.Therefore utilize municipal sludge to add flyash, grass meal composting, can be agricultural renewable resource product is provided, meet the needs of China's agrochemical product restructuring, realized the comprehensive utilization to environomental pollution sources such as municipal sludge and flyash, grass meals simultaneously, make changing waste into resources.There are very big, long-range social benefit and certain economic benefit.
From world wide, the processing method of disposal of municipal sludge mainly contains the various ways such as burning, landfill, throwing sea and compost.The technology of burning method and equipment are complicated, and energy consumption is large, invest high, and with atmosphere polluting problem; Landfill method is subject to the restriction of land used; Throwing sea can Marine Pollution, to the marine ecosystem human foods chain of unifying, can threaten, and international convention is prohibited; With the municipal sludge of producing after fertilizer method is processed, carrying out agricultural use, have the advantages such as economical and convenient, resourcebility, caused extensive attention, is the highest optimal processing approach of current cry.During High-Temperature Composting technology is that developed country is successful in the development research of 20 beginnings of the century, at present in Britain, the U.S., Germany, Japan and other countries, all extensively adopting During High-Temperature Composting technology to carry out the harmless treatment ，Ru U.S. to municipal sludge approximately has 49% municipal sludge to make fertilizer to impose on farmland or forest land every year.The innoxious farm technology of municipal sludge of Germany ETH/OAM regeneration company research and development overcomes and has solved the innoxious problem with fully utilizing of dewatered sludge, has reduced the cost of municipal sludge harmless treatment, in Germany, is widely used.
Sludge organism fertilizer, organic-inorganic fertilizer are a kind of innoxious, comprehensive treatment techniques of subtracting appearanceization, stabilization.It is to utilize aerobic mesophile, the effect of thermophile bacteria, by organic substance decomposing in mud, and kills disease carrying germ, parasitic ovum and virus, improves mud nutriment in a fertilizer.Effective work for the treatment of of mud is very urgent, and this project solves the good approach of mud hidden danger pressure just.Therefore the technical feasibility that, this project has and in the urgent need to property.
Summary of the invention
For the problem existing in current environmental requirement and this area, the object of the present invention is to provide and a kind ofly can effectively utilize sludge organism fertilizer that mud produces for raw material and preparation method thereof.
The present invention adopts following technical scheme to realize its object: a kind of sludge organism fertilizer, is characterized in that: mainly by following material, according to weight percent proportioning, formed:
Described mud is the primary sludge through compost fermentation;
Described tackiness agent is attapulgite;
The preparation method of described sludge organism fertilizer, it is characterized in that: the preparation process of sludge organism fertilizer is: a. compost fermentation: in primary sludge, be added into enzymatic microorganism starter, the fermentation of banking up of plane buttress formula ground, insert thermometer, by mechanical turning, make it keep 30 ℃-45 ℃ of temperature, moisture 35%-45%, pH5.5-8.0; B. granulate: according to quality proportioning, add humic acids, vegetation charcoal and tackiness agent, stir, utilize pulverizer, stirrer and spray granulating machine to carry out physics granulation, when wherein humidity of materials reaches 40%, it is carried out to granulation, particle diameter remains on 2.5-4mm; C. dry: the particle of moulding is sent into dryer by conveying belt, and dryer inlet temperature is controlled at 80 ℃, and temperature out is controlled at 60 ℃; D. cooling: the product particle after oven dry is sent into cooler by conveying belt, method of cooling mainly be take air-cooled as main, and product particle exceeds the whereabouts of evenly scattering most in cooler, and meanwhile, blower fan blows into a large amount of wind, and product particle is carried out to redrying and cooling; E. screening: cooled product is transported to screen-dividing machine, by specification sub-sieve, one class qualified product, two class substandard products, qualified product metering, packing, warehouse-in and to be tested, substandard product returns to pulverizer, enters secondary granulation, and the diameter of described substandard product is for being less than 2.5mm or being greater than 4mm.
The beneficial effect that adopts technical scheme provided by the invention to reach is: the present invention adopts primary sludge to carry out microorganism fermentation as raw material, organism is carried out to biological degradation and form stable soil ulmin, can reduce its pollution to environment, the organic fertilizer that production fertilizer efficiency is simultaneously good, turns waste into wealth.
