Problems solved by technology

[0014] However, the existing technologies for accelerating the heating rate of compost fermentation have the defects of high energy consumption and high cost.
Existing technologies for applying activated carbon to fertilizers are generally limited to the use of the adsorption properties of activated carbon with medium and low activity, but do not involve its carbon increase and rapid temperature rise characteristics.

Embodiment

[0035] Preparation of activated carbon

[0036] The glass ball is made of a glass composition comprising 50-99wt% glass and 1-50wt% quartz-feldspar porphyry or magnetite, and the diameter of the glass ball is 3 mm for easy handling.

[0037] Take tap water, place the above-mentioned glass balls in a thermos liner-shaped container with a water inlet and outlet, so that the water will pass through instantly as if it were flowing normally. The amount of the glass balls has a certain proportional relationship with the flow of tap water, that is, the water pressure and the thickness of the pipe. Generally, the glass balls of 1 kg to 4 kg can be used for conventional tap water pipes.

[0038] Adopt the following proportioning ratio to prepare glass composition respectively:

example (1

[0039] Example (1): The composition includes: 65.2-79wt% glass and 21-34.8wt% quartz-feldspar porphyry, wherein the glass includes 38-41wt% SiO 2 , 20-23wt% Na 2 CO 3 , 4-6wt% CaCO 3 , 1-3wt% Na 2 B 2 o 4 ·5H 2 O, 1-2wt% NaNO 3 , 1-2wt% Al(OH) 3 , 0.1-1wt% TiO 2 and 0.1-1wt% ZnO, and the glass preferably further includes 3-5wt% Fe 2 o 3 or 0.1-1wt% Li 2 CO 3 .

example (2

[0040] Example (2): The composition includes: 72-85wt% glass and 15-28wt% quartz-feldspar porphyry, wherein the glass includes 49-53wt% SiO 2 , 3-6wt% Al(OH) 3 , 19-23wt% Li 2 CO 3 and 1-3 wt% AlPO 4 .

Abstract

The invention relates to a method for quickly enhancing aerobic fermentation compost temperature, which comprises the following steps: (a) preparing cocoanut active charcoal; and (b) in the early stage of the aerobic fermentation compost temperature rise period, adding the prepared cocoanut active charcoal into livestock manure at one time, thereby quickly enhancing the fermentation temperature to 80 DEG C above. The method provided by the invention fully utilizes the characteristic of high temperature rise speed of carbon, and has the advantages of short compost temperature rise fermentation time, low energy consumption and low cost.

Description

technical field [0001] The invention relates to a method for aerobic fermentation and composting, in particular to a method for aerobic fermentation and composting of poultry manure by adding special coconut shell activated carbon to rapidly increase the fermentation temperature. Background technique [0002] The existing aerobic fermentation composting in my country generally has the following production processes: (1) forced ventilation static pile composting, the temperature of the pile body is above 55 ℃, kept for 20 days, and the production cycle is as long as 90 days; (2) intermittent dynamic condition Stack type high-temperature aerobic fermentation process, the general fermentation period is 50 to 60 days, and the fermentation temperature is above 70°C; (3) intermittent dynamic tank type high-temperature aerobic fermentation process, the fermentation cycle is about 40 days, and the fermentation temperature is above 70°C. [0003] Temperature is one of the important in...
