Problems solved by technology

Because it is slightly soluble in water, or even insoluble in water, it cannot decompose various chemical residues and drug residues in the soil, and cannot achieve the effect of improving the soil. Its nutrients are difficult to be absorbed and utilized by plants, and it cannot achieve organic The role of fertilizers, resulting in a waste of resources

Abstract

The invention relates to a production method for preparing water-soluble humic acid fertilizer by utilizing waste water of bean products. The production method comprises the following steps: 1, addingwaste water of a bean product factory into a reaction kettle, heating to 80 to 90 DEG C, adding strong alkali, adding mineral humic acid according to the proportion of the waste water of the bean products to the mineral humic acid being 100mL:(1.0-1.3)g, adjusting the PH value to be 9, and heating the mixed liquid until boiling; 2, adding mineral humic acid into the boiling mixed liquid accordingto the proportion of the mineral humic acid to the mixed liquid being 1g:(3-3.5)mL, and continuously heating and stirring; and 3, controlling the temperature of the reaction kettle to 90 to 95 DEG C,maintaining for 3 hours, cooling to 85 DEG C and maintaining for 2 hours. The waste water of the bean products and the mineral humic acid serve as the raw materials and are organically combined, so that the resources can be recycled, and the water-soluble humic acid which is easily absorbed and utilized by crops and can effectively improve soil, improve the growth environment of the crops and improve the quality of the crops is produced.

Description

technical field [0001] The invention belongs to the technical fields of environmental protection and fertilizers, and in particular relates to a production method for preparing water-soluble humic acid fertilizers from wastewater of bean products. Background technique [0002] With the progress of the times, in order to protect the health of the people, the country has stricter and stricter requirements on food hygiene and food safety. Some soybean product producers and operators in the form of small manual workshops have been eliminated and replaced by those that can guarantee hygienic conditions. A modern industrial production enterprise that meets the standards and guarantees food safety. The industrial production of soybean products industry will produce a large amount of wastewater discharge, which is also an important source of environmental pollution. However, the soybean peptides, plant proteins, medium and trace elements and some invisible substances required by cr...
