Abstract
The present invention disclose a kind of production method of humic acid liquid compound fertilizer, mainly by papermaking wastewater it is acidified reaction, precipitation extract,（OH）Root dissolving reaction, the synthesis of ammonium humate phosphorus, the synthesis of humic acid potassium, the synthesis of zinc humic acid and total synthetic reaction produce humic acid liquid compound fertilizer.The present invention can make full use of the humic acid in papermaking wastewater, reduce farmland, water quality and environmental pollution, production equipment and technique used is also fairly simple, and 12 kilograms of its effects of liquid composite fertilizer produced using the inventive method are suitable with 50 kilograms of chemical fertilizer effect.
Description
Technical field
The present invention relates to a kind of production method of chemical fertilizer, particularly a kind of production method of humic acid liquid compound fertilizer.
Background technology
At present, most area still largely applies chemical fertilizer, its consequence is soil alkali year by year during proportion of crop planting
Change, be hardened, the organic matter in soil lacks, and production cost also improves year by year, and Higher output is not accompanied by a higher income;On the other hand, paper mill is daily
Many waste liquids for containing a large amount of humic acids are given off, and humic acid can effectively prevent alkalization of soils and hardened, substantial amounts of papermaking
After discharging of waste liquid, the humic acid of many is not only wasted, also creates the pollution of farmland, water quality and environment.
The content of the invention
It is an object of the invention to provide a kind of production method that liquid composite fertilizer is produced using papermaking wastewater.
The object of the present invention is achieved like this：
The dense black waste liquid under papermaking roll is taken, its pH value typically in 12-14, is then produced as steps described below：
（1）, acidification reaction：The 1-2% concentrated sulfuric acid is instilled in the papermaking wastewater that pH value is 12-14, is anti-when pH value is 1-2
Answer terminal.
（2）, precipitation extraction：Cloudy solution after acidifying is precipitated into 1-2 hours, clarified solution is excluded and dries sediment, make
Its water content reaches 13-15%, and humic acid is made.
（3）、（OH）Root dissolving reaction：9-10% ammoniacal liquor is added in Manufactured humic acid（NH4CH）Or 3-4% causticities
Sodium, stir under normal temperature, fulvo acid is made.
（4）, ammonium humate phosphorus synthesis：23-24% fulvo acid is taken, adds 16-17% Diammonium phosphate (DAP)
[（NH4）2HPO4], stirring hydrolysis carries out metathesis reaction 20-30 minutes, and ammonium humate phosphorus is made.
（5）, humic acid potassium synthesis：22-23% fulvo acid is taken, adds potassium sulfate 6-7%（K2SO4）, stir
Mix hydrolysis and carry out metathesis reaction 20-30 minutes, humic acid potassium is made.
（6）, zinc humic acid synthesis：22.5-23% fulvo acid is taken, adds 7-8% zinc sulfate（ZnSO4
7H2C）, stirring hydrolysis progress metathesis reaction 20-30 minutes, zinc humic acid is made.
（7）, synthetic reaction：Take the phosphorus humic acid phosphorus 39-41% produced, humic acid potassium 28-30%, zinc humic acid 29.5-31%
Stirring at normal temperature is uniform in input reactor, that is, humic acid liquid composite fertilizer is made.
Humic acid liquid compound fertilizer production technology of the present invention has the following advantages that：
1st, the humic acid in papermaking wastewater can be made full use of, reduces the pollution of farmland, water quality and environment.
2nd, production equipment and technique are simple.
The inventive method will be further described by embodiment below.
Embodiment 1
After 3000 kilograms of the papermaking wastewater that pH value is 14 is put into reactor, the concentrated sulfuric acid that content is 93% is added
（H2SO4）60 kilograms, stirred when instilling, be acidification reaction terminal when pH value is 1;Cloudy solution after acidifying is being precipitated
Precipitation 2 hours in groove, exclude clarified solution, centrifuge dripping sediment, make its water content that the humic acid for being insoluble in water be made up to 14%
1000 kilograms;After 1000 kilograms of humic acid is put into reactor, then 100 kilograms of the ammoniacal liquor that content is 16% is instilled, stirring is equal
It is even, fulvo acid is made;Each 240 kilograms of fulvo acid of input in a kettle, 230 kilograms, then be separately added into
Diammonium phosphate (DAP) [（NH4）2HPO4] 170 kilograms;Potassium sulfate（K2SO4）60 kilograms, zinc sulfate（ZnSO4 7H2O）70 kilograms, stirring
20-30 minutes are hydrolyzed, produce 410 kilograms of ammonium humate phosphorus, 290 kilograms of humic acid potassium, 290 kilograms of zinc humic acid respectively.By
Manufactured ammonium humate phosphorus, humic acid potassium, zinc humic acid are put into a reactor, and humic acid liquid is made after stirring
990 kilograms of bluk recombination fertilizer.
Embodiment 2
Manufactured 239.5 kilograms of fulvo acid, 229 kilograms, 229.5 kilograms are put into reactor, then divided respectively
Not Jia Ru Diammonium phosphate (DAP) [（NH4）2HPO4] 170.5 kilograms;Potassium sulfate（K2SO4）60.5 kilograms, zinc sulfate（ZnSO4 7H2O）
70.5 kilograms, stirring hydrolysis 20-30 minutes, 410 kilograms of ammonium humate phosphorus, 290 kilograms of humic acid potassium, zinc humic acid are produced respectively
300 kilograms, other techniques can obtain 1000 kilograms of humic acid liquid compound fertilizer with embodiment 1.
