Problems solved by technology

[0006] At present, the status quo of my country's poultry manure treatment technology is summarized: ① used as energy source - raw material for biogas production, its disadvantages are large area, large amount of wastewater generated, which cannot be completely solved; ② used as feed - feed for aquaculture, its disadvantages are: Disadvantages Transportation and use are inconvenient, if used improperly, it will cause water pollution; ③Used as fertilizer-directly used as fertilizer, its disadvantages are inconvenient to transport and use, if it is processed in a fertilizer factory, it will be more difficult to remove odor

Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific embodiment:

[0019] Preferred embodiment:

[0020] In this example, we implement the following steps:

[0021] a, adopt fresh excrement to obtain 2kg dry basis excrement by drying;

[0022] b. Make fresh feces into a 20-60% solution. If it is made into a 40% solution, the weight of the solution is 5kg=fresh feces 2kg+water 3kg;

[0023] c, nitrogen-fixing agent, wherein the addition of nitrogen-fixing agent is 10% of the weight of the above solution, which is 500g, and it is placed until the pH value of the solution does not change;

[0024] d. Under stirring, neutralize the pH value of the solution to 8.5-10.0;

[0025] e, then filter the neutralized solution twice, the filter cloth used for the first time is 60 mesh, and the filter cloth used for the second time is 200 mesh to obtain filtrate and filter residue, after the filter residue is dried by infrared rays Used as fuel, after...

Abstract

The invention discloses a chemical treatment method for poultry excrement. The invention aims to provide a simple and economic chemical treatment method for poultry excrement; and the method is matched with a poultry intensive culture farm to form industrialized production, is safe, clean and environmentally-friendly, and saves a large amount of cost. The method comprises the following steps of: preparing 20 to 60 percent solution by using fresh poultry excrement; adding nitrogen fixing agent; neutralizing the pH value of the solution to be between 8.5 and 10.0; performing filtration by using filter cloth of 60 to 200 meshes; adding bactericide, deodorant and decolorizing agent into the filtrate, stirring the filtrate uniformly, heating, standing, curing, cooling to room temperature, and filtering; detecting the concentration of the filtrate, reclaiming the filtrate when the Baume concentration of the filtrate is more than 25 degrees Be', and stirring and evaporating the filtrate in an evaporation kettle; and cooling and crystallizing the filtrate when the Baume concentration of the filtrate is 40 to 70 degrees Be', and dehydrating the separated crystal to obtain ammonium compound fertilizers. The method is applied to the treatment of the poultry excrement.

Description

technical field [0001] The invention relates to a treatment method of poultry excrement, in particular to a treatment method through chemical process. technical background [0002] With the continuous improvement of people's living standards and the gradual strengthening of environmental protection awareness, the harmless treatment of poultry manure, resource recycling, prevention and elimination of poultry manure pollution in intensive farms, and healthy poultry farming industry are my country's green food, organic The needs of food production and sustainable development of modern agriculture. However, at present, the pollution of poultry manure in rural intensive farms in my country is relatively serious, the environment around the farm is polluted, the water source is polluted, etc. The focus of the problem is that the method of poultry manure treatment is unreasonable. [0003] my country's animal husbandry production has undergone qualitative changes since the implement...
