Description

Intensive production system for breeding and treating kitchen waste by utilizing hermetia illucens

Technical Field

The invention belongs to the technical field of kitchen waste treatment, and relates to an intensive production system for treating kitchen waste by breeding hermetia illucens.

Background

With the rapid development and urbanization of economy, the production amount of kitchen waste is increased year by year, and the pollution problem caused by the kitchen waste is increasingly serious. The kitchen waste is rich in a large amount of organic matters, the recycling of the solid organic matters becomes an important factor of project profitability, and in the traditional process, the solid organic matters are ground into slurry and injected into an anaerobic tank for digestion to produce biogas. Due to the complex components of the garbage, the problems of mechanical abrasion, pipeline blockage, even anaerobic acidification and the like can occur in the links of grinding, pumping, dehydration and the like. In addition, the generated methane needs to be purified and reused, and the problem of the outlet of the generated methane slag also becomes a great difficulty, so that a new method is needed for the resource utilization of the solid organic matters. The method is a better alternative for breeding insects represented by hermetia illucens and the like. The life cycle of the hermetia illucens is 40-45 days, and after 5 stages of eggs, larvae, prepupa, pupae and imagoes, the adult pupae are broken and mated to lay eggs, and then the hermetia illucens survive for about several days and die. In about 10 days after eggs are hatched into larvae, the hermetia illucens larvae live on the nutritional decay, and the food can be efficiently converted into self nutrient substances by taking rotten organic matters such as kitchen waste, animal excrement, animal and plant corpses and the like as food, so that the hermetia illucens larvae are an important part in a natural debris food chain.

Due to the characteristics and the economic value of the hermetia illucens, the perfect solution is provided for breeding the hermetia illucens by utilizing organic matters in the kitchen waste. By utilizing the mode of treating the organic solid waste by the hermetia illucens, the kitchen waste (with the water content of about 80%) can be fed to hermetia illucens larvae, and finally 80% of high-quality insect protein and 20% of nutrient-rich insect manure organic fertilizer are obtained. The cultured insects can be used as protein source feed for the breeding industry, and the insect manure can be directly used as organic fertilizer to return to the field. The organic solid waste is utilized to cultivate the insects, so that not only is the waste treated in large quantity and the waste is changed into valuable, but also a large quantity of cheap production raw materials are provided for the insect breeding system, the production cost is reduced, and the whole treatment process is harmless and is recycled.

At present, the hermetia illucens are bred in two modes, namely a breeding mode mainly based on manual work, workers operate between simple breeding frames, the efficiency is low, and the hermetia illucens cannot be popularized on a large scale. The other is an automatic system culture mode, and the existing system equipment has the disadvantages of complex structure, complex flow, large occupied area, high cost and inconvenience in maintenance and repair. Particularly, in the material distribution and box turning links, more intensive, simple and efficient automation equipment and systems are needed. In addition, the existing cultivation plants generally face the problems of environmental temperature regulation and deodorization. The environment temperature has obvious influence on the growth, development, oviposition and hatching of the hermetia illucens, and the optimum temperature is about 25-30 ℃. When the temperature is reduced to below 15 ℃, the growth is slow or the people sleep in winter, and when the temperature is lower than 5 ℃ or higher than 35 ℃, the people are easy to die. In the aspect of deodorization, the odor in the breeding workshop is rich in ammonia gas, hydrogen sulfide and the like and mainly comes from the decomposition of kitchen waste materials and the metabolism of hermetia illucens. The odor is directly discharged without being treated, so that the environment is easily polluted; however, if the odor of the whole culture plant is collected and treated, the energy consumption of the air draft fan is huge, and the deodorization cost is high.

Each breeding box 7 is pre-inoculated with 4-day-old hermetia illucens larvae.

After the material beating of one cultivation box 7 is completed, the suspension type feeding vehicle 5 is started to horizontally move along the suspension type feeding vehicle track 8, and the material beating is performed on the next adjacent cultivation box 7 on the same layer. The material distribution of the culture box 7 with a single layer is completed along with the horizontal movement of the suspension type feeding vehicle 5.

From top to bottom, after the material distribution of the culture boxes 7 in a single layer is finished, the corresponding feeding control valves 5-2 are closed, then the feeding control valves 5-2 corresponding to the culture boxes 7 in the next layer are opened, and the subsequent next layer is subjected to movable material distribution. The above steps are repeated until all the culture boxes 7 on all the culture racks 6 are completely filled with the culture materials.
