Abstract

The invention relates to a method for preparing humic acid-containing water-soluble fertilizer from alcohol biogas slurry. The fertilizer is composed of alcohol biogas slurry, nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, yellowish-brown potassium humate and an organosilicon surfactant. The fertilizer is prepared from, by weight, 74.0 to 82.0 g of fermented alcohol biogas slurry, 1.2 to 1.4 g of citric acid, 0.19 to 0.21 g of copper sulfate, 12.0 to 14.5 g of potassium nitrate, 7.8 to 8.5 g of diammonium phosphate, 15.5 to 16.5 g of urea, 5.5 to 6.5 g of yellowish-brown potassium humate and 0.1 g of the organosilicon surfactant by uniformly mixing the materials at normal temperature at a pH value of 7.0 to 7.5 under stirring for 25 min so as to allow the materials to be fully reacted and dissolved, stopping stirring of liquid and carrying out filling. The prepared fertilizer is reasonable to prepare and is applied in a fertigation or foliar fertilization manner; and the fertilizer can improve the properties of soil and provide comprehensive nutrient elements for plant growth, is beneficial for crop growth and output improvement and can effectively improve crop quality.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for producing humic acid-containing water-soluble fertilizers by utilizing alcohol biogas slurry. Background technique [0002] The alcohol industry is an important basic raw material industry for the national economy. Alcohol is widely used in chemical, food, daily chemical, medical and health fields. The annual output of alcohol in my country is about 3,000,000 tons, and the raw materials for production are mainly grain (corn, cassava, etc.), and about 80% of the grain alcohol is made from cassava. The alcohol biogas slurry discharged from the distillation process in the alcohol production process is a kind of high-suspended solids and high-concentration organic waste liquid. Its BOD is as high as 20,000-30,000 mg per liter, and its COD is as high as 40,000-50,000 mg per liter. According to statistics, for every 1 ton of ethanol produced, the content of organic m...
