Problems solved by technology

The secondary solid-state fermentation greatly improves the fermentation efficiency, shortens the fermentation time, and the quality of the fermented product is stable, but the operation is relatively cumbersome
[0003] The production time of organic fertilizer by the existing organic waste treatment process can basically be controlled within 48-72 hours, and the production process is often accompanied by waste water and odorous gas

Embodiment 1

[0025] Chicken manure and garden waste (flowering branches, leaves, plant stalks, etc.) from chicken farms were selected in a ratio of 7.5:2.5, respectively, and put into the thermal enzyme reactor for rapid recycling of organic waste, adding 0.1% heat-resistant enzyme and 0.05% thermophilic bacteria agent, the material temperature is 80 ℃, the stirring speed is controlled at 5r / min, the first fermentation, decomposing and exhausting, the exhaust volume per ton of material per hour is 150m 3 , the exhaust time is 18 hours; then the parameters are automatically changed to the material temperature controlled at 90 ℃, the speed of the stirring blade of the thermal enzyme reactor is 10 r / min, and the second exhaust volume is 700 m per ton of material per hour 3 , the exhaust time is 6 hours; after 24 hours of fermentation, the material is discharged, which is an organic fertilizer product, and the cooled organic fertilizer is sampled for inspection and self-inspection. 2011) and n...

Embodiment 2

[0032] The sludge and wood chips from the sewage treatment plant were added to the thermal enzyme treatment reactor for rapid recycling of organic waste in a ratio of 7:3, and 0.1% thermostable enzyme and 0.1% thermophilic bacteria composite decomposing agent were added. Parameters for the first 18 hours In order to keep the material temperature constant at 80℃, the stirring speed is controlled at 3r / min, the initial material humidity is about 65%, and the exhaust volume is 100m 3 / h; 16 hours; then use the setting program to automatically fine-tune the parameters until the material temperature is constant at 90°C, the stirring speed is controlled at 8rpm, and the induced air exhaust volume is 750m 3 / h. After 24 hours of fermentation, the organic fertilizer produced has been tested for conventional indicators, heavy metals and microbial indicators (see Table 3). :

Abstract

The invention discloses a fast organic waste recycling hot enzyme aerobic treatment technology. The fast organic waste recycling hot enzyme aerobic treatment technology comprises the steps of: according to the proportion of (6-8):(2-4), respectively placing organic wastes and crop straw or wood chips into a hot enzyme reactor for stirring for 5-10min, respectively adding 0.05%-0.2% of heat-resistant enzyme and 0.05%-0.3% of thermophilic bacteria according to the weight percentage of the organic wastes and crop straw or wood chips, carrying out primary enzymatic fermentation, thorough decomposition and exhausting through the reactor, controlling the temperature of materials at 70-80 DEG C, controlling the humidity of the materials in the reactor to be 60%-70%, wherein the first-time exhausting amount is 100-500m<3> of per tonnage per hour, the exhausting time is 16-18 hours, and the rotating speed of stirring blade of the reactor is 1-20r / min; 16-18 hours later, finely adjusting the parameters of the hot enzyme reactor automatically, carrying out secondary enzymatic fermentation, thorough decomposition and exhausting, controlling the temperature of the materials to be 80-95 DEG C, the rotating speed of the stirring blade of the reactor to be 1-20r / min for 6-8 hours, wherein the second-time exhausting amount is 150-750m<3> of per tonnage per hour, and the exhausting time lasts for 6-8 hours; and then cooling and sieving, or further pelletizing or embedding to obtain the finished product.

Description

technical field [0001] The invention relates to a thermal enzymatic aerobic treatment process for rapid recycling of organic wastes, belonging to the technical field of environmental protection and comprehensive utilization of renewable resources, in particular to a processing technology for organic wastes, in particular to a rapid recycling of organic wastes thermally Enzymatic aerobic treatment process. Background technique [0002] The most common organic waste treatment methods are still traditional composting. In addition, mechanically assisted composting and secondary solid-state fermentation methods have also been greatly developed in recent years. Although traditional compost fermentation is low in cost, it takes up a lot of space, requires a lot of manpower, is labor-intensive, has low fermentation efficiency, and takes a long time. It usually takes 3-6 months. There is secondary pollution in the fermentation process, and the quality of fermented products is unstabl...
