Description
Technical field：
The present invention relates to the technique that a kind of organic sludge produces organic fertilizer, belong to the processing of biofermentation industry fermentation wastes
Field.
Background technology：
Some waste water are inevitably produced in the production process of starch, glucose and monosodium glutamate, are rich in the waste water
The organic matters such as polysaccharide, amino acid, protein；Waste water after microbiological treatment, obtains sewage and rich in organic matter in environmentally friendly process
Sludge, sewage recycles or qualified discharge after recycled water advanced treatment；The sludge of generation is delivered in glutamic acid concentrated mother liquor,
Directly mixed with glutamic acid concentrated mother liquor, carry out slurry-spraying pelletizing.First, the sludge rich in organic matter concentrates female with glutamic acid
The processing mode of liquid mixing slurry-spraying pelletizing causes very big pressure to simple glutamic acid concentrated mother liquor slurry-spraying pelletizing, adds
Workload；Secondly as sludge and the mixed solution concentration of glutamic acid concentrated mother liquor are high, sediment is more, easily blocks whitewashing
Pipette tips, to production bring certain difficulty, add production cost；Furthermore, the sludge rich in organic matter is concentrated with glutamic acid
The product that mother liquor mixing slurry-spraying pelletizing is obtained, its content of organic matter and total nutrient can not meet organic fertilizer rower (NY525- simultaneously
2012), economic value added is low, can only be used as soil conditioner.
The content of the invention：
It is an object of the invention to provide a kind of by the use of organic wastewater as raw material, high economic value added organic fertilizer is produced
Technique.
The purpose of the present invention is implemented by following technical scheme, and a kind of organic sludge produces the technique of organic fertilizer, its process (1)
Prepared by powder sludge, prepared by process (2) organic fertilizer；Wherein
It is prepared by process (1) the powder sludge：The organic sludge is dried and pulverization process successively, obtains moisture content
≤ 5%, the mesh powder sludge of fineness >=40；
It is prepared by process (2) organic fertilizer：By the powder sludge and Baume degrees is 26-28, temperature is 70-95 DEG C paddy
Propylhomoserin concentrated mother liquor is by weight (4-6)：1 mixing back roll granulation, control glutamic acid concentrated mother liquor temperature, be easy to fertilizer into
Ball；Powder sludge is sufficiently mixed with glutamic acid concentrated mother liquor, by rolling, mutual extruding granulating between granule；Then pass through successively
Cross after drying and sieving, obtain moisture content≤30%, the organic fertilizer of granularity (1-4.75mm) >=90%, the organic fertilizer is packaged into
Storehouse；The unqualified material of granularity returns in prepared by the process (1) powder sludge and re-starts pulverization process.
Further, the glutamic acid concentrated mother liquor is concentrated by glutamic acid mother liquor and is made, and glutamic acid mother liquor is corn fermentation
Afterwards, remaining aminoacids solution after glutamic acid is extracted, mainly containing N, P, K, organic matter and amino acid, making organic fertilizer can be used as
Liquid phase feed；After glutamic acid mother liquor is concentrated, the content of its nutrient and organic matter is improved, and viscosity is improved, it is easy to
Organic fertilizer granulating.
In the glutamic acid mother liquor evaporating concentration process, when its Baume degrees reaches 26-28, glutamic acid concentrated mother liquor is obtained.
Further, the organic sludge is made as follows：Alkaline conditioner is added into organic wastewater, institute is adjusted
State organic wastewater pH to 6-8；The processing of aerobic and anaerobe is then sequentially passed through, activated sludge process AO works can be specifically used
Precipitated after the organic matters such as polysaccharide, amino acid, protein in skill, consumption waste water；Treat that the organic wastewater settling ratio reaches 60-
When 80%, separation of solid and liquid obtains N, P and K in sediment and supernatant, organic wastewater through flocculation sediment, into sediment, makees
For the nutrient of organic fertilizer, the sediment obtains sewage and organic sludge after compression, and the supernatant and the sewage are carried out
Sewerage disposing, obtains recirculated water, the recirculated water is produced available for enterprise, therefore non-wastewater discharge.It is heavy that separation of solid and liquid is obtained
Starch is the organic sludge.
Further, the organic wastewater be starch, glucose and glutamate production during produce waste water any one,
Or two of which or three kinds of mixed liquor.
Further, the alkaline conditioner is KOH or lime.
Advantages of the present invention：
1st, the waste water produced in the present invention using during starch, glucose and glutamate production has been concentrated to give as raw material
Machine sludge and sewage, organic sludge, which is produced, obtains the organic fertilizer of high economic value added, solves the process problem of sludge, change give up into
Treasured, steady quality improves the use value of sludge.
2nd, in the present invention when roller is granulated, added in powder sludge, not only carried using glutamic acid concentrated mother liquor as liquid phase
Nutrient has been supplied, but also has neutralized pH value, while also mitigating the pressure of soil conditioner production.
