[0014] Example 1: Preparation of organic fertilizer

[0015] Such as figure 1 As shown, the fermentation device includes a fermentation tank 1, a liquid pump 8 refill system and an air pump 6 oxygen supplement system. The fermentation tank 1 is divided into a fermentation room 2 and a liquid storage room 5 by a ventilation filter plate 3, and the bottom of the fermentation room 2 is connected to the ventilation filter. A discharge port 4 is set at the joint of the plate 3, the leachate collected in the liquid storage room 5 is refilled into the fermentation room 2 through the nozzle 9, and the air pump 6 provides air for the fermentation room 2 intermittently through the control switch 7.

[0016] The ventilation rate of the air pump 6 is 0.5 L / min, and the continuous ventilation is 10 minutes per hour; the opening rate of the ventilation filter plate 3 is 30%, and the capacity of the liquid storage room 5 is 25% of that of the fermentation room 2; After 3 min the aeration of...

[0019] Example 2: Preparation of organic fertilizer

[0020] Such as figure 1 As shown, the fermentation device was prepared, equipped with an oxygen replenishment system and a leachate refilling system at the same time, the ventilation rate of the air pump 6 was 0.9L / min, and the continuous ventilation was 18min per hour; the opening rate of the ventilation filter plate 3 was 15%, and the liquid storage room The capacity of 5 is 10% of that of fermentation room 2; 5 minutes after liquid pump 8 is drained and recharged, it starts to ventilate and supply air to the fermenter.

[0021] The mixed fermentation materials in the fermentation room 2 are deer dung and corn stalks, the initial moisture content is 70%, the initial carbon-to-nitrogen ratio is 33:1, the crushed length of straw is less than 3.5cm, and the total fermentation time is 15 days. The above fermentation time is 5 days, and the pH is controlled between 6.5 and 7.5.

[0023] Example 3: Preparation of organic fertilizer

[0024] Such as figure 1 As shown, the complete system of the fermentation device is prepared, the ventilation rate of the air pump 6 is 0.6L / min, and the continuous ventilation is 15min per hour; the opening rate of the ventilation filter plate 3 is 20%, and the capacity of the liquid storage room 5 is 20% of the fermentation room 2 ; 4 minutes after the pumping and refilling of the liquid pump 8 is completed, the fermentation tank is ventilated and supplied with air.

[0025] The mixed fermentation material in fermentation room 2 is deer manure and corn stalks, the initial water content is 60%, the initial carbon-to-nitrogen ratio is 30:1, the crushed length of straw is less than 2.5cm, and the total fermentation time is 14 days, of which 50°C and above The fermentation time is 6 days, and the pH is controlled between 6.5 and 7.5.

[0026] By adopting the method of the invention, the prepared organic fertilizer has high ...

Abstract

The invention discloses a method for mixing deer feces and corn straw to prepare organic fertilizer. A fermentation device comprises a fermentation tank (1), a liquid pump (8) refilling system and anair pump (6) oxygen supplementing system; a fermentation chamber (2) is refilled with leachate collected by a liquid storage chamber (5) through a sprayer (9), and an air pump (6) intermittently supplies air through a control switch (7). The ventilation rate is 0.5-0.9 L / min, and ventilation is continuously conducted for 10-18 min per hour; 3-5 min after a liquid pump (8) conducts pumping drainageand refilling, air is supplied for the ventilation of the fermentation tank. Mixed fermented materials in the fermentation room (2) are the deer feces and the corn straw, the initial water content is50-70%, the initial carbon-nitrogen ratio is 28:1-33:1, the crushed length of the straw is less than 3.5 cm, the fermentation temperature is controlled at 50 DEG C or above, and the fermentation timeis 12-15 days. The organic fertilizer prepared by means of the method is high in fertilizer efficiency and low in cost.

Description

technical field [0001] The invention relates to the technical field of environmental ecological energy in environmental science and engineering, in particular to a method for preparing organic fertilizer by mixing deer dung and corn stalks. Background technique [0002] my country's air pollution remains high, especially in the autumn of each year, farmers burn corn stalks, which greatly increases air pollution. The current treatment methods for corn stalks include combustion heat energy utilization, crushing as animal food, anaerobic fermentation to prepare biogas, composting to prepare organic fertilizers, and preparation of trace biochar. Pollution is serious, and the method of burning straw is limited. Except for the leaves of the straw, because the fiber content of the stem body of the straw is high, it is not suitable for digestion by animals after eating. Therefore, the utilization of straw is limited to a certain extent. The application of corn stalk crushing to pr...
