  因餐厨垃圾水分含量高,增加焚烧燃料的消耗,增加处理成本。因此,餐厨垃圾处理行业发展中存在的问题,已成为人们关注的焦点。

Due to the high moisture content of kitchen waste, the consumption of burning fuel is increased and the treatment cost is increased. Therefore, the problems existing in the development of kitchen waste treatment industry have become the focus of people's attention.

 

 

  餐厨垃圾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 garbage 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,传统处理技术主要包括填埋和焚烧,资源化处理技术主要包括好氧堆肥、饲料处理和厌氧发酵。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 and incineration, while the resource treatment technology mainly includes aerobic composting, feed treatment and anaerobic fermentation. 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.

 

 

  焚烧法对餐厨垃圾的热值有要求,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;因此,餐厨垃圾不适合用焚烧工艺处理。

Incineration method has requirements on the calorific value of kitchen waste. It is generally used to treat combustible waste 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. And high moisture content will lead to combustion in the incinerator; Therefore, kitchen waste is not suitable for incineration process.

 

 

  在循环利用技术中,好氧堆肥是微生物降解厨余中有机物的过程,包括好氧生物处理和堆肥处理。餐厨垃圾处理含有一个丰富的有机质、适量的水分、均匀的营养物质元素进行配比,十分适合中国微生物的生长。因此,在一定的积累状态下,餐厨垃圾中的微生物自然生长繁殖,降解有机物,最终产生稳定的富含腐殖质的有机肥。

In recycling technology, aerobic composting is the process of microbial degradation of organic matter in kitchen waste, including aerobic biological treatment and composting treatment. Food waste treatment contains a rich organic matter, appropriate amount of water, uniform nutrient elements ratio, is very suitable for the growth of microorganisms in China. Therefore, under a certain accumulation state, the microorganisms in kitchen waste grow and reproduce naturally, degrade organic matter, and eventually produce stable organic fertilizer rich in humus.

 

 

  餐厨垃圾含有丰富的淀粉、纤维素、蛋白质、脂肪和无机盐,脱水后可制成蛋白饲料,餐厨垃圾处理中饲料处理一度被认为是一种很好的资源化处理方式。然而,由于厨房垃圾富含淀粉、纤维素、蛋白质、脂质和无机盐,因此被脱水成蛋白质饲料。

Food kitchen waste is rich in starch, cellulose, protein, fat and inorganic salt, which can be made into protein feed after dehydration. Feed treatment was once considered as a good way of resource treatment in food kitchen waste treatment. However, because kitchen waste is rich in starch, cellulose, protein, lipids and inorganic salts, it is dehydrated into protein feed.
