The problems in the treatment of kitchen waste in Haidian District, Beijing are collected disorderly and the disposal is not standardized. According to the survey, in the catering industry, most of the kitchen waste is directly used to raise “garbage pigs†or to make “water-repellent oilâ€. There are few, no strict and standardized management systems, and there are certain difficulties in the collection, storage and processing. The lags in regulations, the lack of management of kitchen waste, and the wide range of treatments are not obvious.
Lack of mature processing technology At present, the treatment of kitchen waste is still based on the production of organic fertilizer. Due to its high production cost, the fertilizer market is less competitive. At the same time, the kitchen waste treatment technology is currently in the process of development. The resources cannot be fully utilized, resulting in waste of resources.
Beijing Haidian District, kitchen waste treatment measures Beijing Haidian District, kitchen waste treatment started late, the foundation is thin, and more debts. At present, the contradiction between the huge amount of kitchen waste generated and the lack of facilities handling capacity and the serious shortage of funds is very prominent. With the continuous development of the market economy, the existing domestic garbage disposal and management system can no longer meet the requirements, and it is necessary to implement the industrialization development strategy.
From the aspects of government management, law enforcement, education and training, we will reduce the impact of pollution in the food service industry on the water environment through policy-oriented and economic support, supplemented by administrative intervention. The kitchen is resourced. Compared with food waste produced by food processing and food wholesale and retail, kitchen waste is not only high in water content and organic matter, but also has higher fat content and salinity than other garbage. Kitchen waste has a high recycling value. Its main components are starch, dietary fiber, animal fat, etc. It is rich in C, N and protein, and is a rich resource for animal feed and organic matter.
The cost of processing with a small biochemical processor is too high, and the biological strains added to it need to be further studied according to the characteristics of the kitchen waste; how to solve the deodorization problem in the process of efficient and economical research also needs to be studied; composting The quality of the food waste is affected to some extent by the oil content and salt content of the kitchen waste. The high-salt compost product will inhibit the growth of the plant. If it is used for a long time, it will lead to the salinization of the soil, so how to reduce the salt in the compost The amount of the product and its effect on plant growth remains to be further studied.
