Embodiment 1

[0039] The ecological purification device used to treat the excrement of cultured animals, its schematic diagram is as follows Figure 5 Shown, comprise feces input port 1, aerobic digester 2, air pipe input port 3, ecological purification container 4, air pipe input port 6 and solid / liquid output port 7, the ecological purification agent of described ecological purification container 4 and Water, ecological purifier and water enter through the input port 5 of the ecological purifier, and feces enter the aerobic digester 2 through the feces input port 1 for aerobic digestion to form solid digests, which are sent to the ecological purification container 4 for full exposure. Gas is then discharged through the solid / liquid output port 7, and the solid / liquid output port 7 is discharged to connect the separator; wherein, in parts by weight, the excrement of cultured animals is 2 parts by weight, the ecological purifier is 0.06 parts by weight, and water is 40 parts by weight In th...

Embodiment 2

[0046] The ecological purification device for processing the excrement of cultured animals is the same as the ecological purification device of embodiment 1, wherein, in parts by weight, the excrement of cultured animals is 2.5 parts by weight, the ecological purifier is 0.075 parts by weight, and the water is 35 parts by weight; In the aerobic digester, the feces of cultured animals are stored in the presence of oxygen for 4 weeks to obtain solid digestate, and then enter the ecological purification container, where they are contacted with the ecological purification agent for aeration. The aeration time is 7 days, and the aeration The condition is; let the air pass through the air pipe input port 3 under positive pressure at 2.5m 3 The rate of / (L h) passes through the ecological purifier; after the aeration cycle is completed, the solid in the aerated ecological purifier is settled under gravity for 30min, and the air is passed through the air pipe input port 6, under positi...

Embodiment 3

[0053] The ecological purification device for processing the excrement of cultured animals is the same as the ecological purification device of embodiment 1, wherein, in parts by weight, the excrement of cultured animals is 4 parts by weight, the ecological purification agent is 0.1 parts by weight, and the water is 28 parts by weight; In the aerobic digester, the feces of cultured animals are stored in the presence of oxygen for 5 weeks to obtain solid digestate, and then enter the ecological purification container, where they are contacted with the ecological purification agent for aeration. The aeration time is 6 days, and the aeration The condition is; let the air pass through the air pipe inlet 3 under positive pressure at 3m 3 The rate of / (L h) passes through the ecological purifier; after the aeration cycle is completed, the solid in the aerated ecological purifier is settled under gravity for 35min, and the air is passed through the air pipe input port 6, under positiv...

Abstract

The invention discloses an ecological purification device for treating feces of cultured animals, which comprises a feces input port, an aerobic digester, an ecological purification container, an air pipe input and a solid / liquid output port, and the ecological purification container contains an ecological purification agent and water , the ecological purifier and water enter through the input port of the ecological purifier, and the feces enter the aerobic digester through the feces input port for aerobic digestion to form solid digesta, and the solid digesta is sent to the ecological purification container for full aeration, and then passed through solid The / liquid output port is discharged, and the solid / liquid output port is discharged to connect to the separator; the ecological purifier is made of Al-containing 30 The aluminum sol, theaflavin, phytic acid, montmorillonite powder, sweet potato powder, and superphosphate are stirred and mixed in deionized water; The degradation rate, the degradation rate of the total nitrogen concentration and the total phosphorus concentration, and the ecological purifier with excellent bacteria reduction rate are used to treat the ecological purification device of the cultured manure.

Description

technical field [0001] The invention belongs to the field related to the treatment of cultured animal excrement, and in particular relates to an ecological purification device for treating cultured animal excrement. Background technique [0002] With the rapid growth of my country's economy, the quality of life of the people has improved, and the consumption of livestock and poultry products has also increased year by year. The consumption of meat has increased rapidly at an average annual rate of nearly 10%. Intensive large-scale pig farming The rapid rise of the meat market has met the market's large demand for meat food, but it has also brought environmental pollution. The rapid increase of pollutants from livestock and poultry breeding has caused serious pollution to water sources, soil and atmospheric environment. A large amount of high-ammonia nitrogen, high-suspended solids, and high-concentration sewage produced by pig farms is difficult to treat and has become an im...
