Abstract

The invention discloses an inorganic conditioner using production wastewater in the starch industry and a preparation method of the conditioner, and belongs to the technical field of conditioner preparation. The inorganic conditioner is prepared from, by weight, 70-80 parts of soil conditioner, 50-60 parts of humic acid, 15-20 parts of distilled water and 0.6-0.8 part of insecticide composition. The inorganic conditioner using production wastewater in the starch industry is prepared through the steps of humic acid preparation, insecticide composition preparation, mixing, granulation, drying and the like. The inorganic conditioner can promote rooting of crops on the basis of achieving the soil conditioning effect, the lodging phenomenon is reduced, insect pests can be effectively prevented, and yield can be improved.

Description

technical field [0001] The invention belongs to the technical field of conditioning agent preparation, and in particular relates to an inorganic conditioning agent utilizing starch industrial production wastewater and a preparation method thereof. Background technique [0002] The starch industry is an industry that uses corn, potatoes, wheat, rice and other agricultural products as raw materials to produce starch or starch deep-processing products (starch sugar, glucose, starch derivatives, etc.). At present, the annual output of starch in my country is more than 3 million tons. In the starch production process, the water demand is very large, and the waste water discharge is also large. The waste water discharged per ton of starch is 10-20m 3 . Starch industry production wastewater is high-concentration organic wastewater containing a large amount of starch, protein, sugar, fat and other organic matter. If it is not treated and directly discharged into the water body, it ...
