Problems solved by technology

[0002] Most of the oil feet after refining in vegetable oil factories are discarded, incinerated or buried. This is not in line with the current principle of full utilization of energy resources. At the same time, it also causes great pollution to the natural environment.
With the advancement of energy resources recycling technology, there are also methods of recycling vegetable oil and oil residues, such as the technology of using vegetable oil residues to synthesize oil residue asphalt -- "China Building Waterproofing" 2001 04, the method of comprehensive utilization of vegetable oil residues- - "Food and Oils" 1999 04 - Oil recovery from rancid vegetable oil residues, but so far, there is no method of using vegetable oil residues to produce fertilizers

Embodiment 1

[0009] After saponification of the cottonseed oil feet from the vegetable oil factory to remove neutral oils, 60% of the cottonseed oil feet after saponification and removal of neutral oils and 40% of waste plant ash from biological power plants are fully After stirring, add 10% ammonium bicarbonate, and ferment in the fermentation tank, the fermentation temperature is 20-35°C, and the fermentation time is about 15 days. After the fermentation is completed, the organic compound fertilizer product is obtained by granulation, drying, and aseptic treatment. After inspection, the product meets the NY525-2002 standard, and the test results are shown in Table 1.

Embodiment 2

[0011] After the rapeseed oil feet from the vegetable oil factory are saponified to remove neutral fats, 50% of the cottonseed oil feet after saponification and removed neutral fats, and 30% of the waste plant ash from the biological power plant are taken based on the total weight of the fermented material After fully stirring, add 20% ammonium bicarbonate, and ferment in the fermentation tank, the fermentation temperature is 20-35°C, and the fermentation time is about 15 days. After the fermentation is completed, the organic compound fertilizer product is obtained by granulation, drying, and aseptic treatment. , the product was tested and met the NY525-2002 standard, and the test results are shown in Table 1.

Embodiment 3

[0013] After saponifying the soybean oil residues from the vegetable oil factory to remove neutral oils, 55% of the cottonseed oil residues after saponification and removal of neutral oils, and 35% of the waste plant ash from the biological power plant are taken as the total weight of the fermented material. After stirring, add 10% ammonium bicarbonate, and ferment in the fermentation tank, the fermentation temperature is 5-10°C, and the fermentation time is about 20 days. After the fermentation is completed, the organic compound fertilizer product is obtained by granulation, drying, and aseptic treatment. After inspection, the products meet the NY525-2002 standard.

Abstract

The invention discloses a method for producing fertilizer by utilizing vegetable oil residues, which comprises extracting neutral oil from vegetable oil residues, adding plant ash and ammonium bicarbonate, stirring well, stacking and fermenting or fermenting in a fermentation tank, and then It only needs to be processed; the post-processing includes granulation, drying and aseptic treatment. The method of the present invention can turn waste into valuables in vegetable oil factories, and turn pollutants into beneficial objects, which is in line with the current theme of saving energy resources and environmental protection. At the same time, the method has simple operation and low production cost. The compound fertilizer obtained by the method has reached the industry standard NY525‑2002 of the Ministry of Agriculture.
