Abstract

The invention relates to the technical field of sewage treatment, in particular to a method for producing organic fertilizer from wastewater produced in a process for extracting chlorophyll from silkworm excrement. The organic fertilizer is prepared from raw materials as follows: 80.47-88.9 parts of silkworm excrement wastewater, 1-3 parts of urea, 0.3-1.2 parts of potassium fulvate, 0.3-1.5 parts of enzymes, 1-2 parts of compound amino acid, 0.2-0.3 parts of multivitamins, 0.1 parts of nitrogen fixing, phosphate solubilizing and potassium releasing bacteria, 0.1 parts of trichodermin, 0.1 parts of polypeptin, 0.1 parts of phytohormone, 3-10 parts of silkworm excrement micro powder, 3-6 parts of an emulsifier, 0.2-1 part of a thickening agent and 0.4 parts of a preservative. The wastewater produced in the process for extracting the chlorophyll from the silkworm excrement is utilized as the raw material and contains multiple nutritive substances capable of being absorbed by plants, so that the problem that a large amount of wastewater produced in the process for extracting the chlorophyll from the silkworm excrement is difficult to treat is solved, meanwhile, the water resource is saved, and requirements of energy conservation and environmental production are met.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for producing organic fertilizer by using the waste water produced in the process of extracting chlorophyll from silkworm excrement. Background technique [0002] Silkworm excrement is the feces excreted after eating mulberry. It is dark green in color and granular, and its size increases with age. It is as small as fine sand at the first age, and as large as mung bean at the fifth age when it is full of food. One box of silkworm eggs (10g ants, 25,000 silkworms) ), 100-150kg of fresh silkworm manure can be obtained at the whole age, and 50-55kg of air-dried silkworm excrement or about 45kg of dried silkworm excrement can be obtained after air-drying. Composition of silkworm manure: crude protein accounts for 16.7 parts, crude fat accounts for 3.7 parts / crude fiber accounts for 19 parts, soluble nitrogen-free matter accounts for 45 parts, and ash content accoun...
