Embodiment 1

[0048] Preparation of secondary isolates

[0049] (1) Livestock and poultry waste water is poured into the regulating tank, and then 0.01-3% of additives are added according to the weight percentage for aeration and stirring, and at the same time, it is treated with ultrasonic waves. The ultrasonic frequency range is 20-100kHZ, and the ultrasonic intensity range is 0.1-70W / cm 2 , Ultrasonic response time 0.1 ~ 60min. The auxiliary agent is one or a mixture of deodorants and microbial regulators.

[0050] Ultrasonic treatment preferably has an ultrasonic frequency of 40kHZ and an ultrasonic intensity of 40W / cm 2 , Ultrasonic response time is 3min.

[0051] (2), the waste water of the regulating tank after the treatment of step (1) is separated through a grid coarse sieve, and large particles are removed to obtain a primary isolate. The waste water of the regulating pond is injected into the separation tank, and 0.01~ 3% of the auxiliary agent is aerated and stirred for aerob...

Embodiment 2

[0068] Preparation of secondary isolate step is the same as in Example 1

[0069] The preparation of organic fertilizer consists of the following components:

[0070] 90kg of secondary isolate; 5kg of humic acid; 7.5kg of ammonium diammonium phosphate; 0.3kg of zinc sulfate; 1kg of potassium sulfate; 4kg of biogas microbial agent; 0.4kg of naphthaleneacetic acid;

[0071] The preparation steps are the same as in Example 1.

Embodiment 3

[0072] Embodiment 3, it is made up of following composition:

[0073] 98kg of secondary isolate; 4kg of humic acid; 6kg of ammonium diammonium phosphate; 0.2kg of zinc sulfate; 1.2kg of potassium sulfate; 5kg of biogas microbial agent; 0.3kg of coenzyme A;

[0074] The preparation steps are the same as in Example 1.

Abstract

The invention relates to a method for preparing organic fertilizers through livestock wastewater separation, in particular to a method for preparing organic fertilizers through mixing livestock wastewater and humic acid type raw materials and an application, and belongs to the technical field of novel organic fertilizers and the technical field of waste resource circulation utilization. Major ingredients of the organic fertilizers are livestock wastewater separation substances, and in addition, humic acid, diammonium phosphate, zinc sulfate, potassium sulfate and other additives are added. The method has the advantages that biogas residues are used for preparing the organic fertilizers, wastes are changed into resources, in addition, the preparation method is simple and convenient, the required equipment is simple, and the method is easily popularized and applied in fertilizer industry. The solubility of the fertilizers is good, the nutrients are complete, and the yield increase and the quality improvement effect are obvious. The organic fertilizers can be widely applied to vegetables, melons and fruits, grains, forests and various cash crops.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to an organic fertilizer prepared by mixing livestock and poultry wastewater separation and humic acid raw materials and a preparation method thereof, belonging to the technical field of new organic fertilizers and the recycling of agricultural waste resources Take advantage of technical areas. Background technique [0002] With the development of large-scale breeding industry, the country regards the development of large and medium-sized biogas projects as an effective measure to relieve energy pressure and reduce the disposal of livestock and poultry manure. According to statistics, by the end of 2007, my country had built 26.5 million households using biogas, 18,000 small-scale biogas projects with a total pool capacity of 700,000 cubic meters; 8,576 large and medium-sized biogas projects, including large-scale biogas projects (greater than 300m 3 ) nearl...
