Embodiment 1

[0046] (1) Cut off the crop straw through pretreatment and dedust it, and then enter the separation section to separate hemicellulose, cellulose and lignin. Among them, the separation process produces a small amount of waste liquid, and the lignin stock solution is filtered to produce membrane treatment. Supernatant liquid and lignin, the separated hemicellulose is liquid phase, that is, hemicellulose liquid;

[0047] (2) The first liquid phase is obtained after the hemifiber liquid is mixed with a small amount of waste liquid, enters the waste water treatment system, and enters the sump through the grid machine;

[0048] (3) The first liquid phase in the sump passes through the sewage lifting pump and enters the microfilter to filter to obtain the second liquid phase;

[0049] (4) Add flocculant to the second liquid phase, and enter the first settling tank to settle to obtain the third liquid phase;

[0050] (5) The third liquid phase enters the pre-acidification tank, and n...

Abstract

The invention relates to a straw organic liquid and particularly relates to a preparation method of the straw organic liquid specially used for crops. The preparation method includes the steps of: 1) pre-treating crop straws and separating the crop straws to obtain hemi-cellulose liquid, cellulose and lignin, wherein a less amount of waste liquid and membrane treatment supernatant are generated during the separation; 2) mixing the hemi-cellulose liquid with the waste liquid, filtering, flocculating and precipitating the mixed liquid, adding nitrogen and phosphorus and performing membrane treatment to obtain a fourth liquid phase, and performing anaerobic fermentation and vacuum pressure reduced concentration, and adding a strong activator and a plant nutritional growth promoter to produce the straw organic liquid specially used for crops. The straw organic liquid specially used for crops has comprehensive and balanced nutrients, is quick in effect and can increase germination ratio of crop seeds and seedling quality, is short in production period and is low in production cost and high in yield, can solve the problems of long production period, high production cost and low yield of a liquid fertilizer in the prior art.

Description

technical field [0001] The invention relates to a straw organic liquid, in particular to a preparation method of a special straw organic liquid for crops. Background technique [0002] The hemicellulose liquid separated from biomass raw materials (crop straw) has the characteristics of incomplete nutrition, poor fertilizer efficiency, short duration, and does not have both bactericidal and insecticidal effects, so it needs anaerobic fermentation treatment. However, these anaerobic fermentation liquids (biogas slurry) are not fully recognized as fertilizers due to their low nutrient concentration, poor fertilizer efficiency and short duration, and do not have both bactericidal and insecticidal effects. processed or directly discharged into rivers and lakes by people. The air is polluted above, the earth is polluted in the middle, and the water source is polluted below. Most of the large-scale straw resource utilization enterprises are restricted by the relevant departments ...
