Embodiment 1

[0034] Step 1: Mix duck manure with a water content of 92% and bran particles with a particle size range of 1-1.5mm, adjust the water content of duck manure to 72%, and cut the mixture of duck manure and auxiliary materials to make the duck manure and auxiliary materials The mixture is in a semi-fluid state, and the weight of 0.15% of the weight of duck manure associated with black soldier fly larvae is added, and the mixture is uniform to obtain a duck manure mixture, which is set aside;

[0035] Step 2: spread the duck manure mixture obtained in step 1. The thickness of the duck manure mixture is 8cm, and then the 3rd instar larvae of the black soldier fly are placed in the duck manure. The addition of the 3rd instar larvae of the black soldier fly is 130g / t at room temperature Keep it at 30-32°C, and control the relative humidity of the environment at 70%-75%. After 6 days of treatment, the water content of the duck manure mixture will drop to 48%, and the fresh insects will...

Embodiment 2

[0039] Step 1: Mix duck manure with a water content of 89% and edible fungus slag particles with a particle size range of 1-1.5 mm, adjust the water content of duck manure to 68%, and cut the mixture of duck manure and auxiliary materials to make duck manure and The mixture of auxiliary materials is in a semi-fluid state, and the weight of 0.10% of the weight of duck manure associated with bacteria of black soldier fly larvae is added, and the mixture is evenly mixed to obtain the duck manure mixture, which is set aside;

[0040] Step 2: Spread the duck manure mixture obtained in Step 1. The thickness of the duck manure mixture is 10cm, and then connect the 3rd instar larvae of the black soldier fly to the duck manure. The addition of the 3rd instar larvae of the black soldier fly is 150g / t at room temperature. Keep it at 30-32°C and control the relative humidity of the environment at 70%-75%. After 5 days of treatment, the water content of the duck manure mixture will drop to ...

Embodiment 3

[0044] Step 1: Mix duck manure with a water content of 95% and bran particles with a particle size range of 1-1.5mm, adjust the water content of duck manure to 78.8%, and cut the mixture of duck manure and auxiliary materials to make the duck manure and auxiliary materials The mixture is in a semi-fluid state, and the weight of 0.15% of the weight of duck manure associated with black soldier fly larvae is added, and the mixture is uniform to obtain a duck manure mixture, which is set aside;

[0045] Step 2: Spread the duck manure mixture obtained in Step 1. The thickness of the duck manure mixture is 5cm, and then connect the 3rd instar larvae of the black soldier fly to the duck manure. The addition of the 3rd instar larvae of the black soldier fly is 150g / t at room temperature. Keep it at 30-32°C and control the relative humidity of the environment at 70%-75%. After 7 days of treatment, the water content of the duck manure mixture will drop to 43%, and sieve to separate the f...

Abstract

The invention provides a new mode duck manure harmless and resource utilization method which comprises the following steps that 1, duck manure and auxiliary materials are mixed, the mixture of the duck manure and the auxiliary materials is sheared to enable the mixture of the duck manure and the auxiliary materials to be in a semi-fluid state, hermetia illucens larva associated microbial inoculants are added, the mixture is mixed to be uniform, and a duck manure mixture is obtained for use; 2, the duck manure mixture obtained in the step 1 is flatly laid, then 3-year-old hermetia illucens larvae are inoculated into duck manure to be treated for 5-7 days, fresh insects are screened to be separated from duck manure residues, and the fresh insects are processed to be used as livestock, poultry and pet feed; 3, the duck manure residues are uniformly mixed with auxiliary materials, a fermentation inoculant is added and stacked, and static aerobic composting fermentation is performed; and 4,after composting fermentation treatment, aging is performed to be used as an organic fertilizer. According to the method, hermetia illucens is used for biologically converting the duck manure into insect protein, the moisture content of the duck manure is reduced, biological composting is better facilitated, and the problems that the duck manure harmless treatment cost is high, and the resource utilization benefit is low are solved.

Description

technical field [0001] The invention belongs to the field of duck manure treatment, in particular to a new mode and method for harmless treatment and resource utilization of duck manure. Background technique [0002] With the scale and intensification of meat duck breeding, the pollution of duck manure in duck farms to the environment has become more and more prominent, and has become one of the bottlenecks that plague the healthy development of the meat duck industry. [0003] Ducks are waterfowl, and their feces are high in water and rich in nutrients (see Table 1). However, the nitrogen in duck manure is mainly in the form of uric acid, which cannot be directly absorbed and utilized by crops, and is harmful to the growth of crop roots. At the same time, fresh Manure is easy to attract underground pests and requires harmless treatment. The main substance content of duck manure is as shown in Table 1: [0004] average moisture content Average solid content or...
