Problems solved by technology

[0007] At present, there are three kinds of industrial enzyme preparation filter residues, one is high-temperature calcination, and the fertilizer is returned to the field, which is characterized by high investment and high cost.
The second is drying, but a lot of peculiar smell will be produced during the drying process, causing secondary pollution
The third is not to deal with it, and to discharge it randomly, causing environmental pollution problems. At present, most domestic manufacturers adopt the third method

[0022] The slow-release fertilizer of the present invention comprises the following components: carbon ammonia, superphosphate, potassium sulfate, industrial enzyme preparation filter residue, and clay binder.

[0023] For the fermentation of industrial enzyme preparation filter residue, dig 5 meters wide and 3 meter deep ponds on the ground, and adjust the length according to the annual production of enzyme preparation filter residue. The filter cake of the preparation is stacked in the pond, 30-50 cm higher than the pond, and after regularization, it is tightly covered with a plastic film and sealed for 4 months for fermentation and maturation, and then it is recycled in sequence.

[0024] By weight, 20% carbon ammonia, 10% superphosphate, 5% potassium sulfate, 40% fermented industrial enzyme preparation filter residue, 20% white clay binder are stirred in a mixer, and the water is adjusted. up to 40%.

Abstract

The invention discloses a slow release fertilizer which comprises the following components: a nitrogen source, calcium superphosphate, potassium sulfate, industrial enzyme preparation filter residuesand an adhesive. The invention is a low-cost technical solution provided aiming at the post-extraction filter residue treatment of industrial enzyme preparations, particularly high-viscosity fermentation liquor. According to the characteristics that the industrial enzyme preparation filter residues contain lots of bentonite with an adsorption effect, silica, ammonium sulfate, thallus and other organic and inorganic fertilizers, the enzyme preparation filter residues are stacked and fermented, inorganic nitrogen, phosphorus and potassium elements are added, an adhesive is added, and wet granulation and drying are performed so as to prepare the high-value agricultural slow release fertilizer. The slow release fertilizer can be widely applied to fertilizers for wheat, corn, apples, vegetablesand flowers.

Description

technical field [0001] The invention relates to agricultural fertilizers, in particular the invention relates to a slow-release fertilizer produced by using industrial enzyme preparation filter residue. Background technique [0002] my country is a big country in the production of industrial enzyme preparations. There are more than 200 enzyme preparation manufacturers in the country, which produce a large amount of enzyme preparation filter residues every year. How to deal with the filter residue of enzyme preparations has become a headache for manufacturers. After the high-temperature treatment is used by the international enzyme giant in China, the fertilizer is returned to the farmers for free as fertilizer. Due to the high cost of this part, most domestic manufacturers are unwilling to invest, and they basically dump them randomly, causing environmental problems, causing unbearable disturbance to residents, and it is difficult for environmental protection departments to...
