Embodiment 1

[0023] Take 100L of wastewater from an alcohol production plant and put it into a microwave digestion tank, add 47L of nitric acid digestion solution with a hydrogen ion concentration of 2mol / L to soak the wastewater for 1.5h, and then turn on microwave irradiation for digestion. The microwave frequency is 110GHZ, and the duration of the digestion reaction is 15min. After the digestion reaction, add ammonia water to adjust the pH value to 7, and add 10 kg of nano-diatomaceous earth.

[0024] The above-mentioned acid solution was selected from the product of Shenzhen Dingqing Chemical Co., Ltd., and the microwave digestion instrument was the ETHOS A type digestion instrument produced by Milestone Company in Italy.

Embodiment 2

[0026] Take 100L of wastewater from an alcohol production plant and put it into a microwave digestion tank, add 47L of nitric acid digestion solution with a hydrogen ion concentration of 2mol / L, soak for 2h, and then turn on microwave irradiation for digestion. The microwave frequency is 300GHZ, and the duration of the digestion reaction is 20min. After the digestion reaction, add ammonia water to adjust the pH value to 8, and add 20 kg of nano diatomite.

[0027] The above-mentioned acid solution was selected from the product of Shenzhen Dingqing Chemical Co., Ltd., and the microwave digestion instrument was the ETHOS A type digestion instrument produced by Milestone Company in Italy.

Embodiment 3

[0029] Take 100L of wastewater from an alcohol production plant and put it into a microwave digestion tank, add 47L of nitric acid digestion solution with a hydrogen ion concentration of 2mol / L, soak for 1h, and then turn on microwave irradiation for digestion. The microwave frequency is 300MHZ, and the duration of the digestion reaction is 3min. After the digestion reaction, add ammonia water to adjust the pH value to 6, and add 1 kg of nano-bentonite.

[0030] The above-mentioned acid solution was selected from the product of Shenzhen Dingqing Chemical Co., Ltd., and the microwave digestion instrument was the ETHOS A type digestion instrument produced by Milestone Company in Italy.

Abstract

The invention discloses a preparation method of carbon balance organic liquid fertilizer. The preparation method comprises that organic waste as a raw material and an acid undergo a digestion reaction in an enclosed reaction vessel under microwave irradiation for 3-20min, wherein the acid for the digestion reaction comprises one or more of nitric acid, sulfuric acid, perchloric acid and hydrogen peroxide, a mass ratio of the organic waste to the acid is (10-1): 1 and microwave frequency is in a range of 300MHz-300GHz, and after the digestion reaction, a nanometer synergist is added into the digestion reaction product, wherein the nanometer synergist comprises one or more of nanometer diatomite, nanometer bentonite and nanometer silica. Through synergism of acid digestion and microwave digestion, the micromolecule organic compound easily absorbed by crops is obtained and can provide carbon for the crops and balance crop carbon content.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing organic liquid fertilizers that meet the carbon balance requirements of crops by using organic wastes as raw materials. Background technique [0002] Agriculture is one of the pillars of national economic development, and chemical fertilizers are the material basis for sustainable agricultural development and the guarantee for increasing grain production. With the gradual expansion of construction land and the relative shortage of arable land, improving soil fertility through fertilization is an important guarantee for sustainable land use and agricultural development. It has been reported in the literature that the utilization rate of nitrogen fertilizer in my country is only 20-50%, that of phosphorus fertilizer is 15-25%, and that of potassium fertilizer is 30-35%. The low utilization rate of fertilizers leads to huge waste of resources, and also re...
