Description
Technical field
The invention belongs to biofermentation industry Wastewater treating fields, and in particular to include xanthan gum fermentation waste
The preparation method of compound fertilizer.
Background technique
Xanthan gum is the biotechnology for passing through aerobic fermentation using carbohydrate as primary raw material by Xanthomonas campestris,
A kind of high viscosity water soluble polysaccharide is generated, the modern production of xanthan gum is to issue with purebred culture medium in strict control condition
Ferment generate, due to the polysaccharide have very high viscosity, rheology thixotropy and stable physicochemical property, and it is nontoxic pretend for addition
Agent has a vast market foreground in field of household chemical, is widely used in food, medicine, oil recovery, weaving, ceramics, printing and dyeing, perfume (or spice)
The fields such as material, cosmetics and fire-fighting.The waste generated in xanthan gum production process, including mycoprotein and high-concentration waste water its
Processing difficulty is larger, higher cost, it is difficult to obtain the relatively high byproduct of sexual valence.Patented technology " a kind of benefit before applicant
The fertilizer prepared with Threonine Fermentation waste " prepares amino acid chelate fertilizer by the way of hydrolyzing mycoprotein, but the party
Method contains metal ion and is not suitable for preparing bacterial manure.
It is Main Stage that the development of China's fertilizer and application history, which are from farmyard manure to inorganic fertilizer is used, because of farmyard manure dirt
Dye source is more, and freight volume is big, and operationally time-consuming and laborious and effect is not particularly evident；And inorganic fertilizer composition is single, utilization rate
It is lower, and often will cause soil hardening and with soil erosion polluted source, influence ecological environment.Currently, market is adopted more
With the inorganic composite fertilizer etc. of Nitrogen-and Phosphorus-containing potassium, the fertilizer efficiency of the compound fertilizer is comprehensive, not lasting but there is also fertilizer efficiency, is easy loss etc. and lacks
It falls into；Importantly, the price of compound fertilizer is higher at present, biggish burden is brought to peasant, how to reduce fertilizer cost, improved
Farmers' income is the agricultural modernization technical issues that need to address.
Summary of the invention
In order to overcome the drawbacks of the prior art, the present invention provides the preparations of the compound fertilizer comprising xanthan gum fermentation waste
The compound fertilizer of method, this method preparation is effectively utilized amino acid fermentation waste, reduces fertilizer production cost, and it is useless to realize change
For treasured, and fertilizer efficiency is lasting, has both weeding function.
For achieving the above object, the invention adopts the following technical scheme:
The preparation method of compound fertilizer comprising xanthan gum fermentation waste comprising following steps: step 1) xanthan gum hair
The filtering of ferment waste, step 2 hydrolysis, step 3) prepare microorganism formulation A, and step 4) prepares microorganism formulation B, step 5) system
Preparation zymotic fluid A, step 6) prepare fermentation liquid B, and step 7) prepares regulator, and step 8) mixes and drying.
Specifically, the preparation method includes the following steps:
Step 1) xanthan gum fermentation waste filtering: the xanthan gum fermentation waste mistake that microbial fermentation xanthan gum is generated
Mycoprotein and waste water are collected in filter；
Step 2 hydrolysis: mycoprotein is dried, and pulverizer is pulverized into powder, and is subsequently placed in reactor tank, is added
The hydrochloric acid of 5mol/L is subject to and does not cross raw material, and stirring hydrolysis 24 hours at a temperature of 60 DEG C, mixing speed is 300 turns/min, instead
With, with remaining hydrochloric acid, the pH for controlling solution is 6.8-7.2 in ammonium hydroxide after should terminating；
Step 3) prepares microorganism formulation A: by arthrobacterium, bacillus megaterium, azotobacter chroococcum, bacillus polymyxa point
It Pei Yang be not 1 × 10 to concentration8Then the bacterium solution of a/ml is mixed according to the volume ratio of 2:2:1:1 to get microorganism formulation A；
Step 4) prepares microorganism formulation B: trichoderma aureoviride, pseudomonas aeruginosa, candidiasis are cultivated respectively to dense
Degree is 1 × 107Then the bacterium solution of a/ml is mixed according to the volume ratio of 3:2:2 to get microorganism formulation B；
Step 5) prepares fermentation liquid A: rice straw is crushed to obtain rice straw powder, then with wheat bran, rapeseed dregs and
Fishbone dust is mixed evenly to obtain mixture, and the waste water for accounting for the step 1) of twice of mass of mixture is added, and impregnates 12 hours, then
Boil 15min, be cooled to room temperature, according to 10%(v/v) inoculum concentration kind microorganism formulation A, be 28-30 DEG C of condition in temperature
Fermentation 36 hours, obtains fermentation liquid A；Wherein, rice straw powder, wheat bran, rapeseed dregs and the mass ratio of fishbone dust are 5-9:4-
7:3-4:2-3；
Step 6) prepares fermentation liquid B: rice straw being ground into rice straw powder, is added in the solution of step 2, is stirred
It mixes uniformly, stands 12 hours, then successively add dregs of beans, vinasse, conch meal, potassium dihydrogen phosphate and glucose, 500 revs/min
Clock stirs 3 minutes, then is heated to 100 DEG C with the heating rate of 5 DEG C/min, then keeps the temperature 30min, cooled to room temperature is pressed
According to 10%(v/v) inoculum concentration microbe inoculation preparation B, in pH6.8-7.2, the condition fermentation 36 that temperature is 28-30 DEG C is small for control
When, obtain fermentation liquid B；Wherein, rice straw powder, the solution of step 2, dregs of beans, vinasse, conch meal, potassium dihydrogen phosphate and Portugal
The mass ratio of grape sugar is 15-20:100-120:12-18:6-7:6-7:3-5:1-2；
Step 7) prepares regulator: humic acid, bentonite and attapulgite being mixed according to the mass ratio of 2:1:1 and stirred
It mixes uniformly, then grinds, cross 200 meshes up to regulator；
Step 8) mixes and drying: fermentation liquid A, fermentation liquid B, regulator are mixed according to the mass ratio of 6-9:5-7:1-2,
Stir evenly, then freeze-drying be prepared into dry powder to get.
Preferably, the arthrobacterium is CGMCC No.7779, and the bacillus megaterium is CGMCC No.3770, described
