Abstract
The invention provides a production method for a liquid organic fertilizer by using starch wastewater. The method comprises the following steps: step 1, filtering wastewater discharged during production of corn starch or wheat starch to remove foreign materials and adding the wastewater having undergone filtration into an enclosed container; step 2, inoculating a starter accounting for 5 to 10% of the weight of the wastewater for anaerobic fermentation, wherein the starter is prepared from lactobacillus acidophilus and saccharomyces cerevisiae in a weight ratio of 1: 1, fermentation temperature is 30 to 35 DEG C, and fermentation is completed when the pH value of fermentation broth decreases to less than 3.5 according to detection results; and step 3, adding 3 to 5 wt% of ferrous sulphate into the fermentation broth. The method provided by the invention can both effectively mitigate pollution of the wastewater to the environment and realize utilization of the waste, and the prepared liquid organic fertilizer has the advantages of small investment, simple process, substantial fertilizer efficiency, low production cost, remarkable competitive advantages and great market potential.
Description
Technical field
The present invention relates to a kind of production method of agricultural fertilizer, be specifically related to a kind of method of utilizing starch wastewater to produce liquid organic fertilizer.
Background technology
Wheat starch and W-Gum extensively use in industrial production and daily life, but can produce a large amount of waste water in its production process, in waste water, contain the organic constituents such as a certain amount of starch, piperylene, protein, directly discharge can cause serious environmental pollution.The treatment process of starch wastewater all adopts the treatment process of sanitary sewage at present, and activated sludge process, can discharge after COD is up to standard.The research of utilization of starch wastewater is a lot, as utilizes starch wastewater to produce biogas, and because natural pond liquid cannot effectively utilize and process, the treatment process of this maturation is also gradually abandoned.Utilize in addition starch wastewater to produce microbial flocculant, single cell protein, pulullan polysaccharide, microbial pesticide etc., because complex process, the reasons such as product cost height also cannot be implemented.
Summary of the invention
The technical problem that the present invention solves: a kind of method of utilizing starch wastewater to produce liquid organic fertilizer is provided, overcome the defect of above-mentioned prior art, can effectively alleviate the pollution of waste water to environment, can realize utilization of waste material again, and invest littlely, technique is simple, fertilizer efficiency is remarkable, production cost is low, and competitive edge is strong, and market potential is large.
The present invention is achieved through the following technical solutions:
Step 1: will be added in encloses container after the waste water filtering foreign material of production W-Gum or wheat starch discharge;
Step 2: carry out anaerobically fermenting by the 5-10% inoculating starter that adds waste water weight, it is formulated that described starter is pressed 1:1 weight ratio by Lactobacterium acidophilum, yeast saccharomyces cerevisiae, leavening temperature 30-35 ℃, drops to 3.5 when following when detecting fermented liquid PH, and fermenting process completes;
Step 3: press the interpolation of 3-5% weight ratio and press ferrous sulfate in above-mentioned fermented liquid.
The discharge of wastewater time of using in described step 1 is no more than 2 hours.
In described step 1, use the stainless steel mesh filtering foreign material that sieve aperture is 2-3mm.
The advantage that the present invention has and effect:
1, the present invention's metabolism and conversion through microorganism by starch wastewater, finally becomes the liquid microbe fertilizer that is rich in beneficial microbe colony and multiple secondary metabolite.
2, the liquid organic fertilizer that contains milk-acid bacteria, organic acid (take lactic acid as main), ferrous sulfate that the present invention produces, can Promoting plant growth, regulating plant rhizosphere PH, promote the release of soil phosphorus, potassium, calcium and various trace elements, the have additional nutrients validity of element, can also directly supplement highly active ferro element.
3, the present invention can effectively alleviate the pollution of waste water to environment, can realize utilization of waste material again, and invests littlely, and technique is simple, and production cost is low, and market potential is large, has competitive edge.
Embodiment
Step 1: be added in encloses container after the waste water of producing W-Gum or wheat starch discharge is used to the stainless steel mesh filtering foreign material that sieve aperture is 2-3mm;
Step 2: carry out anaerobically fermenting by 8% inoculating starter that adds waste water weight, it is formulated that described starter is pressed 1:1 weight ratio by Lactobacterium acidophilum, yeast saccharomyces cerevisiae, leavening temperature 30-35 ℃, drops to 3.5 when following when detecting fermented liquid PH, and fermenting process completes;
Step 3: add and press ferrous sulfate by 4% weight ratio in above-mentioned fermented liquid.
The discharge of wastewater time of using in described step 1 is no more than 2 hours.Because surpass 2 hours above starch wastewaters, to grow miscellaneous bacteria quantity too many, can not use as fermentation raw material.
The organic fertilizer of above-mentioned explained hereafter has following effect and feature:
1, physicochemical property: light brown liquid, has acidic smell, below PH3.5.Main component is milk-acid bacteria, organic acid (take lactic acid as main) and ferrous sulfate.
2, main effect:
1) Promoting plant growth: structure and the effect of lactic acid similar plants Endogenous auxin (indolylacetic acid), milk-acid bacteria is beneficial microbe colony in soil, lactic acid and milk-acid bacteria foliage-spray, filling root, have the plant stem-leaf of promotion tissue growth, promotes the effect of root system development.
2) regulating plant rhizosphere PH, promotes the release of soil phosphorus, potassium, calcium and various trace elements, the validity of the element that has additional nutrients.
3) directly supplement highly active ferro element.
3, effect: the soil in NORTHWEST CHINA area mostly is calcareous soil, and soil ph is higher, the fruit trees such as plantation peach, Kiwifruit, apple, normal appearance is because the fruit tree yellowing that iron deficiency, scarce zinc bring out is sick.Produce at present the upper main method that adopts foliage-spray, soil to execute ferrous sulfate and prevent and treat, but effect is all undesirable.The organic fertilizer that the present invention produces, contains highly active ferrous ion, and foliage-spray can effectively supplement ferro element, fills with root and can improve rhizosphere environment.A large amount of field tests have been made in Mei County, Yi Shaanxi Province, Pucheng County, Liquan County etc. at present.Test-results shows, the organic fertilizer that the present invention produces has significant prevention effect to yellows, the little leaf disease of the multiple fruit trees such as Kiwifruit, apple, crisp pears, grape.
The present invention compared with prior art market outlook is wide, the EM microbial inoculum of selling on agricultural materials market at present, in fact be exactly lactic acid bacteria formulation, with edible sugar, be that raw material is produced by anaerobically fermenting, 20 yuan/kilogram of market price, and the present invention utilizes 2 yuan/kilogram of the market price of the organic fertilizer that starch wastewater produces, and lactic acid content is higher than the former, has competitive power on market.
Above-described embodiment, is preferred embodiment of the present invention, is not used for limiting the scope of the present invention, thus all equivalent variations of being done with content described in the claims in the present invention, within all should being included in the claims in the present invention scope.
