  餐厨垃圾处理是餐饮垃圾和厨余垃圾的总称,指餐馆、饭店、单位食堂、家庭日常生活等饮食剩余物以及食物下脚料、剩菜剩饭、肉食、油脂、蔬菜瓜果等,是城市生活垃圾的主要组成成分,具有含水率高、有机质占比高、含盐量高、易生化降解等特点。

Eat hutch waste disposal is the floorboard of the food waste and kitchen waste, restaurant, hotel, canteen, family daily life such as eating leftovers and food scraps, leftovers, meat, oil, vegetables, melons and fruits, etc., is a major component of urban living garbage, with high moisture content, organic matter, high proportion, high salinity and easy biochemical degradation characteristics.

 

  目前,我国餐厨垃圾处理技术主要包括传统处理技术和资源化处理技术。其中,传统处理技术主要有填埋法、焚烧法等,资源化处理技术主要有好氧堆肥、饲料化处理、厌氧发酵等。具体来看,在传统餐厨垃圾处理技术中,填埋法具有简单、投资小的特点,但填埋处理资源化水平极低,并以污水量大、污水处理困难、堆体稳定性差及资源浪费为重大代价。

At present, China's kitchen waste treatment technology mainly includes traditional treatment technology and resource treatment technology. Among them, the traditional treatment technology mainly includes landfill method, incineration method, etc., and the resource treatment technology mainly includes aerobic composting, feed processing, anaerobic fermentation, etc. Specifically, in the traditional kitchen waste treatment technology, the landfill method has the characteristics of simple, small investment, but the level of landfill treatment resources is very low, and with a large amount of sewage, sewage treatment difficulties, poor stability and waste of resources for the significant cost. 

 

  焚烧法对餐厨垃圾处理的热值有一定要求,一般用于处理有相当热值的可燃性垃圾,如木材、纸张等,对含水率较高的餐厨垃圾就不适宜直接焚烧,因为水分含量高会增加焚烧燃料的消耗,增加处理成本;且高含水率会导致焚烧炉内燃烧不完全,促进二噁英的生成;因此,餐厨垃圾不适合用焚烧工艺处理。

Incineration method has certain requirements for the calorific value of kitchen waste treatment. It is generally used to treat combustible garbage with a considerable calorific value, such as wood, paper, etc., and it is not suitable for direct incineration of kitchen waste with a high moisture content, because the high moisture content will increase the consumption of incineration fuel and increase the processing cost. The high moisture content will lead to incomplete combustion in the incinerator and promote the generation of dioxins. Therefore, kitchen waste is not suitable for incineration process.

 

  在资源化处理技术中,好氧堆肥是利用微生物对餐厨垃圾中的有机质实现降解的过程,包括好氧生物处理、堆肥化处理。餐厨垃圾含有丰富的有机质、适量的水分、均匀的营养元素配比,十分适合微生物的生长。因此在一定的堆积状态下,餐厨垃圾中的微生物自然生长繁殖,使有机质降解,最终生成稳定的富含腐殖质的有机肥料。

Aerobic composting is a process of using microorganisms to degrade the organic matter in kitchen waste, including aerobic biological treatment and composting treatment. The kitchen waste is rich in organic matter, proper amount of water and uniform ratio of nutrient elements, which is very suitable for the growth of microorganisms. Therefore, in a certain state of accumulation, the microorganisms in the kitchen waste grow and reproduce naturally, degrade the organic matter, and eventually generate stable organic fertilizer rich in humus.

 

  饲料化处理曾被认为是资源化处置的良好方式,因餐厨垃圾处理中含有丰富的淀粉、纤维素、蛋白质、脂类及无机盐,可将其脱水后制成蛋白饲料。但由于餐厨垃圾中含有丰富的淀粉、纤维素、蛋白质、脂类及无机盐,因此将其脱水后制成蛋白饲料。

Feed processing has been considered as a good way of resource disposal, because the kitchen waste is rich in starch, cellulose, protein, lipids and inorganic salts, which can be dehydrated to make protein feed. But because the food kitchen waste contains rich starch, cellulose, protein, fat and inorganic salt, so it will be dehydrated into protein feed.
