Problems solved by technology

[0003] According to the survey on the current situation of silkworm excrement treatment in the silkworm area in South China, it is found that in addition to most of the silkworm excrement being discarded at will, some silkworm households will use the silkworm excrement as fertilizer after composting and retting, but most of the processing methods are simple, just simple composting and retting without turning over Therefore, the surface and bottom of the heap, silkworm excrement cannot form aerobic composting fermentation conditions, resulting in insufficient fermentation, and cannot generate enough high temperature to kill pathogens, and the sterilization is not complete
[0004] At present, there are no research reports on the harmless composting of silkworm excrement pathogens. This method is aimed at solving the pollution of silkworm excrement waste in silkworm areas, the harmlessness of silkworm diseases and the reduction of environmental pollution. A simplified static composting method for silkworm excrement

Embodiment 1

[0021] (1) Drain the bottom of the cement pool, use red bricks to elevate it about 10cm, and lay straight bamboo strips. The gap between the bamboo strips should be small to prevent the compost material from leaking from the gap. The bottom of the pool is in a state of natural ventilation without obstructions.

[0022] (2) Spread a layer of dried and crushed fungus chaff about 5cm thick on the bamboo strips, and then mix silkworm sand and fungus chaff with a C / N ratio of 12.5:1 and fungus chaff in a ratio of 8:2 by weight. Pour it into the silkworm sand pond, pile it up to 90cm, spread it flat, and then cover the surface with a layer of fungus chaff about 5cm thick.

[0023] (3) Set up temperature measurement points at different locations in the silkworm sand pond. According to the change of pile temperature, it is decided to turn over the pile.

[0024] (4) Put silkworms infected with silkworm microparticle disease into the compost, take samples at intervals of 24 hours, gri...

Embodiment 2

[0027] (1) Drain the bottom of the cement pool, use red bricks to elevate it about 10cm, and lay straight bamboo strips. The gap between the bamboo strips should be small to prevent the compost material from leaking from the gap. The bottom of the pool is in a state of natural ventilation without obstructions.

[0028] (2) Spread a layer of dried and crushed fungus chaff about 5cm thick on the bamboo strips, then pour 80 catties of silkworm sand with a C / N ratio of 15:1, level it, then add 20 catties of fungus chaff, level it, In this way, add silkworm excrement - fungus chaff - silkworm excrement one by one in sequence until the pile is as high as 90cm, spread it flat, and then cover the surface with a layer of fungus chaff about 5cm thick.

[0029] (3) Set up temperature measurement points at different locations in the silkworm sand pond. According to the change of pile temperature, it is decided to turn over the pile.

[0030] (4) Put the diseased silkworm infected with nuc...

Embodiment 3

[0033] (1) Drain the bottom of the cement pool, use red bricks to elevate it about 8cm, and lay straight bamboo strips. The gap between the bamboo strips should be small to prevent the compost material from leaking from the gap. There is no obstruction at the bottom of the pool and it is in a state of natural ventilation.

[0034] (2) Spread a layer of rice husks about 5cm thick on the bamboo strips, and then pour the silkworm excrement and fungus chaff mixture with a C / N ratio of 10:1 and fungus chaff in a ratio of 7:3 parts by weight. Put it into the silkworm sand pond, pile it up to 90cm, spread it flat, and then cover the surface with a layer of fungus chaff with a thickness of about 5cm.

[0035] (3) Set up temperature measurement points at different locations in the silkworm sand pond. According to the change of pile temperature, it is decided to turn over the pile.

[0036] (4) Put silkworms infected with silkworm microparticle disease into the compost, take samples at...

Abstract

The invention discloses an innocent static aerobic composting treatment method for silkworm excrement. The method comprises the following steps of: 1) putting up an open floor on the bottom of a treatment tank; 2) spreading a layer of conditioner on the open floor; 3) pouring mixture of the silkworm excrement and the conditioner on the layer of the conditioner and spreading, or alternately poring the silkworm excrement and the conditioner to obtain a plurality of composite layer piles and then spreading; and 4) finally covering a layer of conditioner on the surfaces of the piles in the treatment tank. A layer of mushroom residues is coated on the bottom of a silkworm excrement tank and the surface of the silkworm excrement respectively, so that the direct contact between the silkworm excrement and natural environment can be avoided, the function of heat preservation can be exerted, and different parts of silkworm excrement have the high enough temperature; and therefore, the whole high-temperature aerobic fermentation effect of the silkworm excrement tank can be guaranteed, the fermentation and composting speed of the silkworm excrement is accelerated, and the effect of killing pathogens in the silkworm excrement can be improved.

Description

technical field [0001] The invention relates to a method for treating silkworm excrement waste, in particular to a harmless static aerobic composting method for silkworm excrement. Background technique [0002] Silkworm excrement is an important waste in sericulture production. In production, it not only refers to the solid feces discharged by silkworm larvae, but also includes leftover mulberry, bedding in silkworm seats, silkworm body and silkworm seat disinfectants, etc. Some sick and dead silkworms and weak silkworm corpses. Due to the unavoidable existence of various infectious silkworm disease pathogens in silkworm excrement, without safe treatment, it is very likely to cause a major threat to production. Especially in the silkworm areas in South China, silkworms can be raised for 8-9 months of the year. The batches of silkworms are connected end to end, and the amount of silkworm excrement is constantly increasing, and the phenomenon of random discarding is serious. ...
