C, addition Fermentation Function bacterium solution, stir, and is placed in sealing container, is placed in 35 DEG C of incubators cultivation 1-2
In week, the venting of sealing article handling once and is stirred, until pH drops to less than 4, is obtained fermentation liquid by every day；
D, above-mentioned fermentation liquid filter, and cross 300 mesh sieves, stay cleaner liquid, using the solid portion of separation as SOLID ORGANIC
Fertilizer, the liquid portion of separation is through high temperature sterilize；
E, add the KOH of 0.1-0.3%, the pH to 6-7 of regulation liquid；
F, the above-mentioned liquid through KOH regulation both can be directly used as Liquid Fertilizer, it is also possible to as one of Liquid Fertilizer raw material, add
Add other nutrient element, make various Liquid Fertilizer.
The innovative point of the present invention is: 1. using molasses regulation pH, play multi-effect, the pH of stock solution is typically at 8.5-
10.5, be not suitable for doing liquid fertilizer, and cane molasses pH is less than 6, therefore, is good regulator；2, cane molasses self has very
Many nutritional labelings, can do Liquid Fertilizer；3. cane molasses can promote the Fast-propagation of EM, uses the method for EM fermentation to kill through a step
Extremely, contain some pathogenic bacterias, worm's ovum, manufacture clean nutritional solution, increase available nutrient content in liquid；4. use doing of fermentation
Method, utilizes beneficial microbe population to kill miscellaneous bacteria, meanwhile, makes full use of the nutrient element such as nitrogenous, phosphorus in cultivation waste liquid higher
Feature, makes Liquid Fertilizer, and processing cost is low, effective.
As preferably, the flocculant that described flocculence uses is PAMC, and consumption accounts for pig farm cultivation waste liquid
The 0.01-0.05% of weight.
As preferably, described molasses are cane molasses, and pH value is 4-6.
As preferably, Fermentation Function bacterium solution is EM bacterium solution, and bacterium solution bacterium number content is no less than 1,000,000,000/milliliter, and addition is
The 0.3-0.5% of total liquid volume.
The invention has the beneficial effects as follows: use the way of fermentation, utilize beneficial microbe population to kill miscellaneous bacteria, fill meanwhile
Point utilizing the feature that in cultivation waste liquid, the nutrient element such as nitrogenous, phosphorus is higher, make Liquid Fertilizer, processing cost is low, effective.
