Problems solved by technology

However, in order to obtain the highest production capacity of biogas in various anaerobic processes and equipment currently available, conventional wet mesophilic anaerobic fermentation is mainly adopted. The yield of biogas slurry is very high and the water quality is extremely complicated, which brings great difficulties to the back-end sewage treatment. The extremely high investment cost and processing cost lead to the high operating cost of the entire kitchen project. Therefore, the present invention proposes a new type of anaerobic fermentation treatment device and method for kitchen waste to solve the above problems

Abstract

The invention relates to the technical field of kitchen waste treatment, in particular to a novel kitchen waste anaerobic fermentation treatment device and method. The novel kitchen waste anaerobic fermentation treatment device comprises a slurrying tank, a dehydration tank, a plate-and-frame filter press, a dry-method anaerobic generation tank, a wet-method anaerobic generation tank and a straintank. Meanwhile, the invention further relates to the kitchen waste anaerobic fermentation treatment method; the kitchen waste anaerobic fermentation treatment method comprises the following specificsteps of (1) purification, slurrying and oil extraction; (2) deep dehydration; and (3) dry and wet separation and anaerobic fermentation. The novel kitchen waste anaerobic fermentation treatment device and method have the beneficial effects that the biogas slurry quantity which is generated after anaerobic digestion is completed is much lower than that of a traditional technology, moreover, the water quality is obviously improved, and COD and ammonia concentrations are significantly reduced, so that investments and an occupied area of a sewage treatment system are greatly reduced compared withthose of a sewage treatment facility of a traditional kitchen waste anaerobic treatment project, and accordingly compared with the traditional kitchen waste anaerobic digestion technology, the novelkitchen waste anaerobic fermentation treatment device and method have significant advantages.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to a novel kitchen waste anaerobic fermentation treatment device and method. Background technique [0002] Food waste, commonly known as swill, is leftovers from catering enterprises and households such as hotels, restaurants, canteens, etc. It mainly includes rice and flour food residues, vegetables, vegetable oils, animal oils, meat grains, fish bones, etc. Animals and plants are rich in Biomass is organic matter. The main directions of food waste are: first, it is used as raw material to feed swill pigs without treatment, which endangers human food safety through the food chain; It harms the health of consumers and endangers food safety; third, it is directly discharged as garbage, which not only blocks urban sewer pipes, emits rancid smell, but also seriously pollutes water sources, causing great pressure on environmental sanitation. [0003] At present, anaero...
