Embodiment Construction

[0031] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0032] The problem to be solved by the present invention is to provide a comprehensive treatment method for kitchen waste that is harmless and can be utilized as a resource.

[0033] Such as figure 1 figure 2 As shown, in order to achieve the technical purpose, the technical solution of the present invention is: a comprehensive treatment method for kitchen waste, characterized in that it comprises the following steps:

[0034] S1: First, dry and wet separation of catering waste is carried out through pretreatment, dry waste is subjected to aerobic fermentation to make organic fertilizer, wet waste is separated by three phases, and concentrated water is input into the anaerobic consumption system for treatment;

[0035] S2: The wastewater is firstly treated through regulation and treatment, and then anaerobic fermentation treatment is carried out, the orga...

Abstract

The invention relates to an integrated treatment method for kitchen waste. By a pretreatment system, an anaerobic consumption system and a sewage treatment system, harmless treatment of the kitchen waste is realized; through resource utilization, integrated governance of the kitchen waste is realized, and grease, organic fertilizers and methane with economic efficiency can be produced; and sewageand odor generated are treated effectively and do not bring secondary pollution to the environment. The technological method is novel and practical; and a recovery rate is high.

Description

technical field [0001] The invention relates to the field of kitchen waste treatment, in particular to a comprehensive treatment method for kitchen waste. Background technique [0002] Food waste is now uniformly treated according to the solid waste treatment method. Treatment methods mainly include physical, chemical, and biological methods. Specific treatment technologies include landfill, incineration, composting, fermentation, etc., and its resource reuse shows a trend of diversification. The landfill method in the prior art is aimed at eliminating garbage, and cannot realize the recycling and reuse of kitchen waste. The requirements for incineration equipment are relatively high, and flue gas treatment equipment is required. The project investment is large and the payback period is long. Moreover, the quality of compost fertilizer is not high, and at the same time, the cost of higher-quality composting methods is relatively high, and it is difficult to promote. The...
