Abstract
The invention discloses a raw material preparing method of liquid fertilizer, which comprises the following steps: adding sulfuric acid into waste liquid from mother liquid of alcohol; breaking residual yeast; sedimenting metal salt; adding pH value to 1-2.5 through surplus sulphuric acid; stewing; sedimenting completely; filtering the sediment to obtain the filtrate as raw material of liquid fertilizer.
Description
Technical field:
The present invention relates to a kind of fertilizer.
Background technology:
A lot of sugar refinery all have and utilize sugar refinery to separate the operation that mother liquor (being commonly called as tangerine water) after the sucrose is made alcohol, tangerine water can produce a large amount of waste liquids after making alcohol, waste liquid is through becoming the liquid of black after concentrating, these liquid normally use as the water reducer of cement, therefore, people are referred to as water reducer again.Because this water reducer contains the composition that great number of organic matters, amino acid etc. can be used as fertilizer, therefore, domestic a lot of liquid fertilizer factory with it as raw material production fluid in next life body fertilizer (as foliage fertilizer).But, because the liquid of this black contains a large amount of yeast and impurity such as calcium, magnesium inorganic salt of comprising, make the liquid of black in the fertiliser production process, generate the paste solid substance easily, these paste solid substances have destroyed liquid fertilizer homogeneous phase structure, have seriously influenced the quality product of final product (liquid fertilizer product).
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of raw material that can not produce the paste solid substance, be the manufacturing liquid fertilizer of homogeneous single-phase liquid state.
The present invention realizes like this, mother liquor after sugar refinery utilizes separation sucrose is made in the waste liquid that produces behind the alcohol and is added sulfuric acid, to destroy unnecessary yeast wherein, and make metal salt precipitate, use in the ammoniacal liquor again and excessive sulfuric acid, add phosphoric acid at last and regulate its pH value, leave standstill then to 1-2.5, throw out is wherein fully precipitated, and the filtrate that obtains after throw out is filtered promptly becomes the raw material of making liquid fertilizer.The present invention is owing to adopted sulfuric acid that the yeast in the waste liquid is destroyed, and metal-salt (mainly being calcium, magnesium metal-salt) is precipitated, the species precipitate that may form paste in the waste liquid is got off, then by regulating its pH value, it is met make the needed acid or alkali environment of liquid fertilizer, like this, the liquid fertilizer made from this raw material (as foliage fertilizer) just can not produce the paste that has a strong impact on its quality.
Here, sulfuric acid is that the weight ratio of sulfuric acid and water is 0.5-1.5: 1 dilute sulphuric acid, the consumption of dilute sulphuric acid are the 10-15% of waste liquid weight.
The concentration of ammoniacal liquor is that the weight ratio of ammonia and water is 1-3: 1.
Concentration of phosphoric acid is 60-80%.
In order to make sulfuric acid can give full play to its effect, sulfuric acid adds under whipped state.
For throw out can fully be precipitated, behind the adding phosphoric acid, stirred at least 10 minutes, and then left standstill at least 1 day.
Compared with the prior art the present invention has the advantage that can not produce the paste solid substance, be homogeneous single-phase liquid state.
Embodiment:
Now in conjunction with the embodiments the present invention is described in further detail:
The mother liquor of the present invention after sugar refinery utilizes separation sucrose made in the waste liquid that produces behind the alcohol and add sulfuric acid under whipped state, to destroy unnecessary yeast wherein, and make metal salt precipitate, use in the ammoniacal liquor again and excessive sulfuric acid, add phosphoric acid at last and regulate its pH value to 1-2.5, leave standstill then, throw out is wherein fully precipitated, the filtrate that obtains after throw out is filtered promptly becomes the raw material of making liquid fertilizer.Sulfuric acid is that the weight ratio of sulfuric acid and water is 0.5-1.5: 1 dilute sulphuric acid, preferably the weight ratio of sulfuric acid and water is 0.8-1.2: 1 dilute sulphuric acid, the consumption of dilute sulphuric acid are the 10-15% of waste liquid weight, preferably 12-13%.The concentration of ammoniacal liquor is that the weight ratio of ammonia and water is 1-3: 1, and preferably 3: 1.Concentration of phosphoric acid is 60-80%, preferably 65-75%.After adding phosphoric acid, stirred at least 10 minutes, preferably more than 20 minutes, and then left standstill at least 1 day, preferably left standstill at least 5 days.
