Problems solved by technology

However, 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 the fertilizer effect is not good. , resulting in a waste of resources

Abstract

The invention relates to a water-soluble humic acid production method, which mainly comprises: adding potato-to-starch wastewater and a strong alkali to a reaction kettle according to a certain ratio,adding mineral humic acid to the boiling mixing solution, controlling the temperature of the reaction kettle, and maintaining for 2-3 h. According to the present invention, potato-to-starch wastewater and mineral humic acid are used as the raw materials, and are organically combined to produce the water-soluble humic acid, wherein the produced water-soluble humic acid is easily be absorbed and utilized by potatoes and other crops, and can effectively improve the soil, such that the potato-to-starch wastewater achieves the zero-emission standard, the problem of resource recycling is solved, and the problem that mineral humic acid cannot effectively improve soil and cannot be absorbed and utilized by crops is solved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a production method of water-soluble humic acid. Background technique [0002] Since the reform and opening up, the national three-agricultural policy has been further broadened to encourage farmers to get rid of poverty and become rich as soon as possible. However, in some areas in the north, restricted by the geographical and climate environment, especially in Gansu, Inner Mongolia, Ningxia, Yulin, Shaanxi and other areas in the north, potatoes have become the mainstay of our country. In the production area, the income of farmers has increased year by year, the planting area has also expanded year by year, and the deep processing of potatoes has also been further accelerated. Large-scale potato deep-processing factories emerged as the times require. A large amount of untreated wastewater after potato starch production has been discharged indiscriminately, causin...
