Embodiment 1~4

[0035] A kind of organic fertilizer based on waste alcohol fermentation waste water is alcohol fermentation waste liquid obtained through the following steps:

[0036] S1. Anaerobic: Send the slag-containing alcohol fermentation wastewater into the anaerobic tank for anaerobic treatment of the whole slag. There are fillers and anaerobic bacteria covering the filler in the anaerobic tank. The anaerobic filler is composed of the following components: As shown in Table 1; the purpose of the above-mentioned anaerobic is to produce the highest concentration of humic acid, not to eliminate COD to the greatest extent in the traditional sense. Specifically, the anaerobic cycle of the anaerobic treatment is 10 days;

Embodiment 1

[0050] Nutrient ingredient is urea among the embodiment 1, and trace element is formed by mixing the trace element in organism and the trace element in non-organism with weight ratio 1:5, and the trace element in described organism is cobalt, and the trace element in non-organism Trace elements in living organisms are rare earths.

Embodiment 2

[0051] Nutrient ingredient is ammonium polyphosphate in embodiment 2, and trace element is formed by mixing trace element in organism and non-organism with weight ratio 1:4, and the trace element in described organism is cobalt, so The trace elements in the above-mentioned non-biological organisms are rare earths.

Abstract

The invention provides an organic fertilizer based on waste alcoholic fermentation wastewater. The organic fertilizer is obtained by the following steps: anaerobic treatment: feeding slag-containing alcoholic fermentation wastewater into an anaerobic jar for full-slag anaerobic treatment, wherein a filler and anaerobic bacteria covering the filler are arranged in the anaerobic jar; solid-liquid separation: carrying out centrifugal separation on the anaerobic wastewater and solid substances in the anaerobic wastewater, and carrying out primary separation on the separated clear liquid; primary purification: realizing separation of insoluble substances, colloids, bacteria, dissolved substances and water, and purifying organic matters; secondary purification: separating soluble organic matters, salt and water; first-stage concentration: enabling the concentrated liquor subjected to reverse osmosis to pass through a low-pressure nano filtration membrane to remove moisture and retain fertilizer components; second-stage concentration: enabling the permeate liquid subjected to the first-stage concentration to pass through a nano filtration membrane, further removing moisture and retaining fertilizer components; and third-stage concentration: enabling the permeate liquid subjected to the second-stage concentration to pass through a reverse osmosis membrane. According to the organic fertilizer based on the waste alcohol fermentation wastewater, humic acid can be obtained to the maximum extent, the ultraviolet radiation resistance of the anaerobic filler is improved, anaerobic filler failure caused by ultraviolet radiation is avoided, and humic acid can be obtained to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production and reclaimed water reuse, in particular to an organic fertilizer based on waste alcohol fermentation wastewater produced by using alcohol fermentation wastewater. Background technique [0002] At present, fertilizers are developing in the direction of high-efficiency compounding, bioactivation and pollution-free. One of the important directions is humic acid fertilizer. Biochemical humic acid is a kind of artificial humic acid. It is a new resource of non-coal humic acid. It contains high biologically active organic acids, which can stimulate the growth of crops. It has obvious advantages and broad application prospects. The advantages of humic acid-rich organic fertilizers based on waste alcohol fermentation wastewater are as follows: small molecular weight, stronger penetration, and easier absorption and utilization by crops; richer active groups, stronger physiological an...
