Problems solved by technology

However, aerobic composting cannot solve the pollution of harmful organic substances and heavy metals. The harmlessness is not complete, and the treatment process is not closed, which is easy to cause secondary pollution. In addition, the composting process takes a long time, covers a large area, and has relatively poor sanitation conditions; the anaerobic digestion project requires a large investment, occupies a large area, and has high operating costs; drying feed cannot avoid the problem of protein homology, and product quality is not guaranteed , there are certain hidden dangers when used as feed

Abstract

The invention provides equipment and a method for synthesizing polyhydroxyalkanoate, and relates to the field of kitchen waste treatment. The equipment for synthesizing polyhydroxyalkanoate comprisesan anaerobic acid production device for producing PHA synthesis raw materials, a PHA synthesis device for synthesizing PHA and a PHA extraction device for extracting PHA, wherein the anaerobic acid production device, the PHA synthesis device and the PHA extraction device are sequentially communicated. The method for synthesizing polyhydroxyalkanoate comprises the following steps: inputting raw materials including kitchen waste into an anaerobic acid production device, carrying out anaerobic fermentation, feeding a product into a PHA synthesis device, and synthesizing to obtain a PHA-containingmaterial; and feeding the material containing PHA into a PHA extraction device, and extracting to obtain a PHA final product. The equipment and the method for synthesizing polyhydroxyalkanoate provided by the invention can effectively utilize kitchen waste, and have the advantages of environmental protection, economy, safety, no secondary pollution and the like.

Description

technical field [0001] The invention relates to the field of kitchen waste treatment, in particular to a device and method for synthesizing polyhydroxyalkanoate. Background technique [0002] Kitchen waste is the most important type of food waste, including food residues produced by families, schools, canteens and catering industries. Its composition is complex, and it is a mixture of various substances such as oil, water, fruit peel, vegetables, rice noodles, fish, meat, bones, waste tableware, plastic, paper towels, etc. The characteristics of kitchen waste are mainly high water content, which accounts for 80-90% of the total garbage; high organic matter content, high oil content, high salt content; easy to rot and deteriorate, easy to ferment, easy to smell; easy to breed parasites Harmful substances such as eggs, pathogenic microorganisms and mycotoxins. [0003] At present, the domestic treatment of food waste mainly uses aerobic composting, anaerobic digestion and dr...
