Embodiment 1

[0031] A harmless treatment process for sericulture waste, specifically comprising the following steps:

[0032] Step 1, take by weighing 50kg of fresh silkworm rearing waste, spray 5kg mass fraction as 10% urea solution; then add 0.25kg ammonium ion solution, 25g feed Bacillus cereus powder, 0.015kg calcium carbonate powder; add to complete Finally, mix the above materials evenly, put them in a 1m*60cm PE plastic bag, and place them in an airtight place for 16 days;

[0033] The ammoniated ion solution is made of 2.5g / L sodium nitrate, 3.0g / L potassium phosphate, 5.0g / L magnesium chloride, 2.0g / L iron sulfate and 2.0g / L ammonium sulfate;

[0034] The number of effective viable bacteria in feed Bacillus cereus powder (Jiangsu Lvke Biotechnology Co., Ltd., 5 billion / g) is 2.5 billion effective viable bacteria per 1 kg of silkworm waste;

[0035] Step 2. Since the excess ammonia generated during the ammoniation process will inhibit the subsequent aerobic fermentation, the materia...

Embodiment 2

[0042] A harmless treatment process for sericulture waste, specifically comprising the following steps:

[0043] Step 1, take by weighing 50kg of fresh silkworm rearing waste, spray 5kg mass fraction as 10% urea solution; then add 0.25kg ammonium ion solution, 25g feed Bacillus cereus powder, 0.015kg calcium carbonate powder; add to complete Finally, mix the above materials evenly, put them into a 50kg plastic bucket, and seal them for 21 days;

[0044] The ammoniated ion solution is made of 2.5g / L sodium nitrate, 3.0g / L potassium phosphate, 5.0g / L magnesium chloride, 2.0g / L iron sulfate and 2.0g / L ammonium sulfate;

[0045] The number of effective viable bacteria in feed Bacillus cereus powder (Jiangsu Lvke Biotechnology Co., Ltd., 5 billion / g) is 2.5 billion effective viable bacteria per 1 kg of silkworm waste;

[0046] Step 2. Since the excess ammonia generated during the ammoniation process will inhibit the subsequent aerobic fermentation, the material put into the plasti...

Embodiment 3

[0053] A harmless treatment process for sericulture waste, specifically comprising the following steps:

[0054] Step 1, take by weighing 50kg of fresh silkworm rearing waste, spray 5kg mass fraction as 10% urea solution; then add 0.25kg ammonium ion solution, 25g feed Bacillus cereus powder, 0.015kg calcium carbonate powder; add to complete Finally, mix the above materials evenly, put them in a 1m*60cm PE plastic bag, and seal them for 30 days;

[0055] The ammoniated ion solution is made of 2.5g / L sodium nitrate, 3.0g / L potassium phosphate, 5.0g / L magnesium chloride, 2.0g / L ferric sulfate and 2.0g / L ammonium sulfate;

[0056] The number of effective viable bacteria in feed Bacillus cereus powder (Jiangsu Lvke Biotechnology Co., Ltd., 5 billion / g) is 2.5 billion effective viable bacteria per 1 kg of silkworm waste;

[0057] Step 2, because the excess ammonia produced in the ammonification process will inhibit the subsequent aerobic fermentation, so the material in the PE pla...

Abstract

The invention belongs to the technical field of comprehensive utilization of sericulture wastes and particularly relates to a harmless treatment technology for silkworm breeding wastes. The harmless treatment technology specifically comprises the following steps: (1) carrying out oxygen-free ammoniation; (2) reducing the concentration of ammonia gas; (3) carrying out aerobic fermentation; (4) detecting the compost maturity and pathogenic microorganisms. By adopting the harmless treatment technology for the silkworm breeding wastes, provided by the invention, the problem that the environment iseasily polluted in storage and centralized transportation processes can be solved; the C / N ratio of the silkworm breeding wastes can be effectively reduced, the aerobic fermentation efficiency at a later stage is improved and the availability of the silkworm breeding wastes is improved.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of sericulture waste, and in particular relates to a harmless treatment process for sericulture waste. Background technique [0002] Sericulture waste contains silkworm excrement (silkworm excrement) and silkworm seat organic waste (undigested mulberry leaves and leftover mulberry branches and leaves and silkworm seat bedding. Silkworm excrement is the solid excrement of silkworms, with a moisture content of 62 to 66 %, containing 18 kinds of amino acids, 2.97% of nitrogen, 1.03% of phosphorus, 3.52% of potassium and trace elements such as copper, iron and zinc in dry matter. According to theoretical calculation, the fertilizer effect of 100kg of dry silkworm excrement is equivalent to 14kg of ammonium sulfate. Silkworm seat Organic waste is mainly some undigested and leftover mulberry branches and leaves and silkworm cushions. Among them, mulberry branches mainly contain cellulo...
