Embodiment 1

[0021] A method for composting mixed composting of discarded edible fungus bags and urban sludge, comprising the steps of:

[0022] 1) Mix the crushed and crushed waste fungus bag, chicken manure and urban sludge evenly, then add water and adjust the water content to obtain the mixed ingredients. Waste bacteria packs, including discarded bacteria packs of oyster mushrooms, shiitake mushrooms, chicken mushrooms, and Coprinus comatus edible fungi, are collected and air-dried naturally, and the urban sludge is fresh sludge with a moisture content of 70-80%, which is discarded in the mixed ingredients The mass ratio of bacterial bag, chicken manure and urban sludge is 100:70:40; the moisture content is 45%;

[0023] 2) Activate the high-efficiency composting fermentation bacteria and inoculate them in the liquid medium for 3 days to cultivate high-efficiency composting fermentation bacteria. The high-efficiency composting fermentation bacteria include deodorizing bacteria and lign...

Embodiment 2

[0027] A method of using edible fungus discarded bacteria bags and urban sludge mixed composting, the steps are basically the same as in Example 1, the difference is:

[0028] 1) The mass ratio of discarded bacteria bag, chicken manure and urban sludge in the mixed ingredients is 100:70:50; the moisture content is 50%;

[0029] 2) The spray inoculation amount of the fermentation bacteria agent is as follows: the inoculum amount of the deodorizing bacteria agent is 2% of the dry matter weight of the composting ingredients, and the inoculum amount of the lignocellulose-degrading bacteria agent is 4% of the dry matter weight of the compost ingredients.

[0030] The experimental results show that after 10 days of fermentation, the compost raw materials can reach maturity, and all indicators meet the requirements of the standard NY525-2002.

Abstract

The invention discloses a method for co-composting waste edible fungi bags and urban sludge. The method comprises the following steps of (1) uniformly mixing squeezed and smashed waste fungi bags, chicken dung and urban sludge, adding water, and adjusting the moisture content to obtain a mixture; (2) respectively activating high-efficiency composting zymophyte, and inoculating the high-efficiency composting zymophyte into a liquid culture medium for cultivation for 3-5 days to respectively prepare high-efficiency composting fermentation bacteria agents; (3) respectively spraying the high-efficiency composting fermentation bacteria agents into the mixture for stacking and fermentation, turning the stacks once every morning and evening, supplementing the water at any time to guarantee the moisture content, and fermenting for 8-12 days to obtain high-efficiency organic fertilizers. The method disclosed by the invention has the advantages of simple technology, easiness in operation and small investment; the prepared fertilizers are high in N, P and K content; solid waste is recycled and is turned into treasures for improving the soil and promoting growth of crops; due to the recycling of the waste edible fungi bags, environmental and economical benefits are achieved.

Description

technical field [0001] The invention relates to the field of organic fertilizer preparation, in particular to a method for mixing and composting waste mushroom bags of edible fungi and urban sludge. Background technique [0002] Edible fungus waste bags are waste materials produced during the production process of edible fungi. Usually, the edible fungus bags are discarded after the mushrooms above the third tide are produced, and the waste bags are often piled up. Because the waste bacteria bag contains a lot of water, it is easy to ferment and deteriorate after being discarded. A large amount of leachate pollutes the soil and flows into rivers and lakes to pollute water sources along the surface runoff. Some bacteria farmers dry the discarded bacteria bags and burn them, but the air pollution is serious. Therefore, the harmless resource utilization of discarded edible fungus bags has attracted people's attention. [0003] In the process of sewage treatment, urban sewage...
