餐饮废物主要由剩馀食物和其他废物组成。 如果将其直接丢弃或当作一般城市垃圾处理，不仅会污染环境并增加城市垃圾处理量，还会造成这些浪费食品的浪费，目前有几种南京餐厨垃圾污水处理方法：

Catering waste mainly consists of leftover food and other wastes. If it is directly discarded or treated as general urban garbage, it will not only pollute the environment and increase the amount of municipal garbage disposal, but also cause the waste of food. At present, there are several methods for the treatment of food waste in Nanjing:

  1.南京餐厨垃圾污水处理-物理分类处理方法，通常使用一系列方法来分离垃圾中的成分，然后对其进行统一回收。 一方面，这种方法可以最大限度地利用最 佳方法，另一方面，可以将垃圾造成的污染最小化。 但是，由于成本高昂，除少数发达国家外，大多数国家都不需要此方法。

Nanjing food waste treatment - physical classification treatment method, usually use a series of methods to separate the components in the waste, and then the unified recycling. On the one hand, this method can maximize the use of the best method, on the other hand, it can minimize the pollution caused by waste. However, because of the high cost, this method is not needed in most countries except a few developed ones.

  2.南京餐厨垃圾污水处理-粉碎直行法。 早在1940年代，美国就已经成功开发了个人家庭食物垃圾处理器。 原理是：使用高速刀片破坏衬里中的食物垃圾，然后将混合物压入下水道。 为了解决居民丢弃和储存食物垃圾的问题。 同时，日本也很早就研究了厨余垃圾处理机，有些甚至使用臭氧除臭剂来清除厨余垃圾中的各种异味。

Nanjing kitchen waste treatment - crushing straight line method. As early as the 1940s, the United States has successfully developed personal household food waste processors. The idea is to use a high-speed blade to break up the food waste in the lining and then press the mixture down the drain. To address the problem of residents discarding and storing food waste. At the same time, Japan has been researching kitchen waste disposal machines for a long time, and some even use ozone deodorant to remove all kinds of odors from kitchen waste.

  3.南京餐厨垃圾污水处理-填埋方法。 垃圾填埋场处理是一种厌氧消化方法，可以分解有机物形成CH4，可以完全处理废物。 该技术是方便的并且不会留下任何处置问题。 但是，这种方法可以更好地处理食物垃圾，但是其目的是消除食物垃圾，无法实现食物垃圾的回收。

Food waste disposal in nanjing - landfill method. Landfill treatment is an anaerobic digestion method that breaks down organic matter to form CH4 and can completely dispose of waste. The technique is convenient and does not leave any disposal problems. However, this method can deal with food waste better, but its aim is to eliminate food waste, not to achieve the recycling of food waste.

  4.南京餐厨垃圾污水处理-厌氧处理法，是目前最环保，最有利可图的方法。 投资高，厌氧发酵产生的沼气很小。因为厨余中含有各种动物肉，例如饲料，所以类似的食物很容易引起口蹄疫和各种疾病，并传播给人类并造成伤害； 由于含水量高，垃圾填埋场容易产生大量的渗水和滤液污染。 地下水; 化肥的使用，生产过程中气味溢出，影响周围环境； 厌氧处理会产生大量沼气，这是一种清洁的可再生能源，可用于发电和燃料。 由于系统是封闭的且无异味，因此厌氧处理厨余垃圾是未来的发展方向。

Nanjing kitchen waste treatment - anaerobic treatment method, is currently the most environmentally friendly, the most profitable method. The investment is high and the biogas produced by anaerobic fermentation is very small. Food waste contains a variety of animal meat, such as feed, which can easily cause foot and mouth disease and various diseases that can be transmitted to humans and cause harm; Due to the high water content, landfill sites are prone to produce a large amount of seepage and filtrate pollution. Groundwater; The use of chemical fertilizer, the production process of odor overflow, affect the surrounding environment; Anaerobic treatment produces large amounts of biogas, a clean, renewable energy source that can be used to generate electricity and fuel. Because the system is closed and odor free, anaerobic treatment of kitchen waste is the future development direction.

  5.南京餐厨垃圾污水处理-堆肥方式，厨余垃圾有机质含量高，营养成分高，碳氮比合理，适合微生物生长和代谢。 它是生产的良好原料。 厨房垃圾堆肥的基本技术可分为两类：厌氧发酵堆肥和好氧发酵消化。 其中，高温好氧堆肥是比较普遍的方法，可以在短时间内完成物料堆肥的成熟过程。 堆肥过程中产生的高温可显着抑制有害细菌。

The food waste treatment - composting method in Nanjing has high organic matter content, high nutrient composition, reasonable C/N ratio, and is suitable for microbial growth and metabolism. It is a good raw material for production. The basic technology of kitchen waste composting can be divided into two categories: anaerobic fermentation composting and aerobic fermentation digestion. Among them, high temperature aerobic composting is a common method, which can complete the maturation process of material composting in a short time. The high temperatures generated during the composting process significantly inhibit harmful bacteria.
