Abstract

The invention relates to a kitchen sewage treatment method. The kitchen sewage treatment method comprises stirring crushing treatment, sewage exposure under sun, first-order biodegradation treatment, second-order biodegradation treatment and third-order biodegradation treatment, and the above five processes are circulated. The kitchen sewage treatment method has a scientific and reasonable process design, a low treatment cost, a short period, simple equipment processes and good operationality, is very suitable for centralized treatment on small-scale kitchen waste produced by newly built residential districts and high-grade restaurants and hotels, utilizes constructed wetland characteristics, and realizes effective treatment on sewage. The device used by the method is prepared from easily available materials, can be assembled simply, has short whole cycle time, has a small land occupation area, is convenient for treatment, can be operated easily and has a good ornamental value.

Description

technical field [0001] The invention relates to the technical field of environmental protection sewage treatment, in particular to a kitchen sewage treatment method. Background technique [0002] Food waste refers to leftovers, expired food, leftovers, waste and other wastes formed in the process of processing and consuming food in restaurants, hotels, canteens of enterprises and institutions, and households. At present, the treatment of food waste is mainly landfill and incineration as domestic waste. On the one hand, such treatment wastes the recyclable resources in food waste, and in addition, the high-salt and high-moisture characteristics of food waste are not suitable for landfill and incineration. deal with. Now some food waste is processed by biochemical technology and used as raw materials to produce fertilizers, feed or to prepare glycerin and biodiesel. However, these technologies are still immature and reliable, and the scope of application is not wide enough. ...
