Abstract
The invention discloses a method for producing an organic fertilizer by using activated sludge, belonging to the field of biological organic fertilizers and aiming to reduce the pollution of the activated sludge to the environment, change wastes into wealth and produce the organic fertilizer by recycling the activated sludge. The technological method disclosed by the invention comprises the steps of: by utilizing the characteristic that the activated sludge contains rich starch, cellulose, fat, proteins and other substance, comprehensively treating the activated sludge by using biological bacterial liquid and an enzymic preparation, wherein the enzymic preparation contains the components as follows: 30-40% of amylase, 25-35% of cellulase, 20-30% of lipase, and 25-35% of protease; and adding bran and other auxiliaries, fermenting in a solid-state fermentation tank at 60 DEG C for 7 hours, drying and crushing to obtain the organic fertilizer. According to determinations based on national standards on the organic fertilizer of the ministry of agriculture in China, relevant indexes of the produced organic fertilizer are all qualified.
Description
Technical field:
The invention belongs to biological technical field, be specifically related to utilize biological bacteria liquid and zymin to handle active sludge jointly, behind microorganism solid fermentation, finally make organic fertilizer.
Background technology:
At present, the fast development along with industry, rural economy produces a large amount of active sludge in activity in production, and the unpleasant gas that these active sludge produced can pollute environment, also is a kind of significant wastage to resource simultaneously.Because active sludge rich in starch class, fats, cellulose family and protein-based etc., these materials all are organic substances, and it is unfortunate really as offal treatment.Based on the needs of China's sustainable economic development, demand finding a kind of method of rational processing active sludge urgently, realize sludge decrementization on the one hand, realize the recycling of active sludge on the other hand.
One Chinese patent application CN200810174378.8, a kind of method of utilizing municipal sludge to produce granular organic fertilizer with high content of humic acid, patent are that municipal sludge, exsiccant weathered coal powder and the phosphogypsum weight proportion according to 80-100: 30-50: 10-30 is mixed; The 2%-4% that presses the raw material gross weight inserts enzymatic microorganism, and fully mixing gets into fermentation vat; Aeration, carry out 10-15 days the fermentation, after ted; Pulverize, the organic aqueous binders granulation of 0.05%-0.1% that adds the comminuting matter amount gets final product.The present invention can improve the balling ratio of granulation process, and making does not have fiber impurity in the product, but fermentation time is longer.
It is the common processing active sludge of biological bacteria liquid and zymin that the present invention utilizes the method for biotechnology with active sludge; After active sludge is realized degraded; Obtain organic fertilizer through the microorganism solid fermentation processing,, the organic fertilizer that is obtained by active sludge production is carried out index of correlation detect according to the national standard of Ministry of Agriculture's organic fertilizer; Through measuring, index of correlation all meets the national standard of Ministry of Agriculture's organic fertilizer.The organic fertilizer that utilizes active sludge to make can be used for agricultural, aquaculture and livestock industry etc.; Can realize the recovery and reuse of resource on the one hand; Alleviate national energy present situation in short supply, also can alleviate pressure on the other hand, purified environment environment; Turn waste into wealth active sludge the final cleaner production that realizes industry and agricultural.
Summary of the invention:
The technical problem that the present invention solves provides a kind of method of utilizing active sludge to produce organic fertilizer.
Utilize active sludge to become the method for product organic fertilizer following:
In active sludge, adding mass ratio is the biological bacteria liquid of 1.5%-7.5%; Said biological bacteria liquid is made up of Bacillus licheniformis, bacillus megaterium, bacillus natto, subtilis, plant lactobacillus, lactobacillus delbrueckii subspecies bulgaricus liquid; Adding mass ratio is the mixing enzyme preparation of 1%-6%, and the active sludge that is added with biological bacteria liquid and zymin is gone into solid-state fermenter, by carrying out solid state fermentation behind the auxiliary materials such as the mass ratio interpolation water of 60%-100% and 10%-30% and wheat bran; Wherein, Solid-state fermenter stirs, and handles initial stage 5h, leavening temperature 40-50 ℃; Handle 1h in mid-term, leavening temperature 55-60 ℃; Handle later stage 1h, leavening temperature 65-70 ℃, fermentation time 1h, fermentation ends is after oven dry promptly gets organic fertilizer after pulverizing.
Said Bacillus licheniformis, bacillus megaterium, bacillus natto, subtilis, plant lactobacillus, lactobacillus delbrueckii subspecies bulgaricus bulk concentration are all 4 * 10
8Individual/ml to 8 * 10
8Individual/ml.
Said Bacillus licheniformis, bacillus megaterium, bacillus natto, subtilis, plant lactobacillus, lactobacillus delbruockii subspecies bulgaricus adopt conventional strain culturing method through the inclined-plane, a secondary shake-flask culture obtains.
Said mixing enzyme preparation is made up of glycase, cellulase, lypase, proteolytic enzyme, polygalacturonase and saccharifying enzyme.
The mass ratio of said mixing enzyme preparation is a glycase: cellulase: lypase: proteolytic enzyme: polygalacturonase: saccharifying enzyme is 0.8-1.2: 1.0-1.2: 0.8-1.0: 1.0-1.4: 0.8-1.2: 0.6-0.8.
The solid-state fermenter mixing speed is at 10-50r/min;
With the cotton-shaped active sludge in sewage work's Aerobic Pond is material; Because organic substances such as active sludge rich in starch, Mierocrystalline cellulose, fat, protein; So the method for utilization biotechnology can effectively be handled the active sludge that is rich in organic substance; The organic fertilizer that finally makes is through measuring, and indexs of correlation such as moisture, organic matter, living bacteria count, pH, excrement colibacillus group number meet Ministry of Agriculture's organic fertilizer standard, and final yield can reach 16%-19%.
Beneficial effect:
The invention provides a kind of technology that can effectively handle active sludge, realized the recycling of active sludge.Simultaneously; The present invention is directed to active sludge rich in proteins class, starch based, fats and cellulose family; Utilization can produce the microbial strains of proteolytic enzyme, glycase, lypase and cellulase, and it is joined in the active sludge, adds a certain proportion of zymin associated treatment active sludge simultaneously; Degradation biological larger molecular organics faster just in fermentation place process effectively improves the speed and the efficient of solid state fermentation.In solid ferment process, pass through the temperature of adjustment hot blast; Under 50 ℃ to 70 ℃ hot conditions, can the pathogenic bacterium in the active sludge be killed, and the microbial strains of in active sludge, adding is high-temperature resistant strain; Can in the higher environment of temperature, well breed; Can increase the probiotics number in the finished product, in addition, Maillard reaction can take place in the reaction process make the product flavouring.Use this method to handle active sludge, meet the treatment principle of innoxious, resource utilization, minimizing, the fertilizer that makes through active sludge; Contain abundant organic matter; By the plant absorbing utilization, use among a small circle more easily, can effectively promote increasing crop yield, instant effect through the experiment field; And can effectively eliminate environment stench, environment purification, and application cost is lower.
