Embodiment 1

[0039] The method for preparing fertilizer by fermenting food waste in this embodiment comprises the following steps:

[0040] (1) crushing the raw material to obtain the crushed raw material;

[0041] Raw materials include straw, perishable vegetables and fruits.

[0042] Perishable vegetables and fruits, including stems and leaves of perishable vegetables Chinese cabbage, lettuce, cabbage, etc., as well as perishable discarded fruits and peels such as apples, bananas, oranges, pears, etc.

[0043] Straws include pepper straws and tomato straws.

[0044] Further, it is crushed until the length and width are less than 5cm.

[0045] In principle, the smaller the raw material is crushed, the easier it is to ferment, but the higher the degree of crushing, the higher the cost. Therefore, the present invention fragments to a size less than 5 cm.

[0046] (2) adding the crushed raw materials in the step (1) into a fermentation tank provided with ventilation pipes at the bottom, ...

Embodiment 2

[0059] The method for preparing fertilizer by fermenting food waste of the present invention comprises the following steps:

[0060] (1) Crushing the raw material until the length and width are less than 5cm to obtain the crushed raw material;

[0061] Further, the raw material includes at least one of straw, perishable vegetables and fruits, and the like.

[0062] Perishable vegetables and fruits, including the stems and leaves of perishable vegetables such as Chinese cabbage, lettuce, cabbage, etc., as well as perishable discarded fruits and peels such as apples, bananas, oranges, pears, etc.

[0063] The straws include vegetable straws, rice straws, etc., and the vegetable straws are at least one of potato straws, cucumber vines, pumpkin vines, loofah vines, pepper straws, tomato straws, and eggplant straws.

[0064] In principle, the smaller the raw material is crushed, the easier it is to ferment, but the higher the degree of crushing, the higher the cost. Therefore, th...

Embodiment 3

[0078] The method for preparing fertilizer by fermenting food waste in this embodiment comprises the following steps:

[0079] (1) crushing the raw material to obtain the crushed raw material;

[0080] The raw materials are perishable vegetables and fruits. Perishable vegetables and fruits, including stems and leaves of perishable vegetables such as Chinese cabbage, lettuce, and cabbage, as well as perishable discarded fruits and peels of apples, bananas, oranges, and pears.

[0081] Broken to less than 5cm in length and width.

[0082] In principle, the smaller the raw material is crushed, the easier it is to ferment, but the higher the degree of crushing, the higher the cost. Therefore, the present invention fragments to a size less than 5 cm.

[0083] (2) adding the raw material crushed in step (1) into a fermentation tank provided with a ventilation duct at the bottom, then adding feces equivalent to 40% of the weight of the raw material after crushing, and adjusting th...

Abstract

The invention discloses a method for preparing a fertilizer by fermenting food wastes. The method comprises the steps of (1) crushing raw materials; (2) adding excrement, and adjusting the moisture content to obtain a mixed solution; and (3) adjusting the pH value to 7.3 to 7.8, and carrying out anaerobic fermentation; after anaerobic fermentation is carried out for 2 to 3 days, when the temperature of the mixed solution is increased to 65 DEG C or above,opening a ventilation pipeline at the bottom of a fermentation tank for air supply and oxygen supply, after ventilation is carried out for 18to 24 hours, closing the ventilation pipeline, repeating anaerobic fermentation and air supply and oxygen supply twice, and obtaining the fermented fertilizer. The fermentation speed is high; microorganisms do not need to be added additionally, and the method is particularly suitable for rural families; the raw materials are wide in application range, rural straw or waste crop resources can be fully utilized for resourceful treatment, reduction and harmless utilization of vegetable straw waste can be effectively achieved, and harm to the environment is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a method for preparing fertilizer by fermenting food waste. Background technique [0002] With the rapid development of my country's social economy, the level of agricultural modernization is increasing day by day, and various characteristic breeding and planting industries are booming all over the country, which not only enriches the ever-expanding market demand, but also greatly drives the increase in the income level of farmers. Agriculture and animal husbandry such as vegetable planting, beef cattle, and dairy cattle breeding have formed a relatively complete industrial structure in some provinces and cities, forming a comprehensive system from planting and raising to post-production primary processing, product deep processing, high value-added product extraction, and domestic and international trade. The whole industrial system. [0003] However, it is worth ...
