Example Embodiment

[0009] The present invention will be further described below in conjunction with specific embodiments.

[0010] (1) Orthogonal experiment selects the above 4 factors and 3 levels, choose L 9 Orthogonal table arranges the experiment to find out the best reaction conditions for the production of superphosphate by traditional methods, see Table 1 and Table 2. The mass ratios of phosphate rock powder and sulfuric acid are: 100 / 60, 100 / 70, 100 / 80; the concentrations of sulfuric acid are: 60%, 65%, 70%; the mixing temperature is: 60℃, 70℃, 80°C; stirring time is 1min, 2min, 3min respectively.

[0011] Add the weighed phosphate rock powder to the sulfuric acid preheated to the specified temperature and stir. The best reaction conditions obtained from the experiment are (that is, the conversion rate of available phosphorus is the highest): the mass ratio of phosphate rock powder and sulfuric acid is 100 / 60, the mass fraction of sulfuric acid is 70%, the mixing temperature is 60°C, and th...

Abstract

The invention provides a method for preparing an organic phosphorus fertilizer by using coenzyme Q10 fermentation liquor. In the method, the coenzyme Q10 fermentation liquor reacts with phosphate rock powder according to a certain proportion to produce calcium superphosphate. The method is rational in technology; high acidity of the coenzyme Q10 fermentation liquor is effectively utilized; and the coenzyme Q10 fermentation liquor reacts with the phosphate rock powder to prepare the calcium superphosphate. By adopting the method, the high-quality organic phosphorus fertilizer can be produced, so that the waste liquor resource can be effectively utilized, the production cost can be reduced, and the pollution caused by the fermentation liquor to the environment can also be relieved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to a method for preparing coenzyme Q10 fermentation liquid into organic phosphate fertilizer. Background technique [0002] Coenzyme Q10 is a quinone ring compound, which plays an important role in proton translocation and electron transfer in the redox carrier of mammalian cell transport chain. Q10 is widely used in the fields of clinical medicine, nutraceuticals, food and cosmetics. At present, coenzyme Q10 is mainly produced by microbial fermentation. However, a large amount of fermentation liquid is produced during the fermentation process, which has the characteristics of low pH (pH value 2-3) and high COD. These fermentation liquids are not treated or treated incompletely. Entering the water body will deteriorate the water quality, cause environmental problems, and destroy the ecological balance. However, using conventional wastewater treatment methods will easily cause exc...
