Problems solved by technology

At present, at the national policy level, although food waste is required to be classified, there is no effective treatment and disposal method, and food waste cannot be effectively reused as resources.
[0005] In addition, with the continuous expansion of the city scale, a large number of dead branches, leaves, grass, straw, wood, sawdust, etc. will be produced in the process of landscaping. Due to the lack of effective treatment methods, most of them are related to domestic waste Together, they are transported to the landfill, causing a lot of waste of resources

Abstract

The invention discloses a method and apparatus for producing biomass fuel by using urban waste. The method comprises: (1), classifying biomass waste, removing metals and plastics, and crushing; (2), classifying kitchen waste, removing metals and plastics, crushing, and dewatering; (3), mixing and stirring the biomass waste, the dewatered kitchen waste and sludge according to a dry-base ratio of parts by weight: 5.5-6.0:1.5-2.0:2.5-3.0, adding 0.001-0.005 L / kg per DS of biological enzyme deodorant into a mixture; (4), extruding the mixture in an extruder into strips; (5), drying the strips at a high temperature of 400 DEG C, and drying at a low temperature of 60-80 DEG C; (6), cooling a dried product to normal temperature to obtain the finished biomass fuel 3500 c / kg in caloric value. The invention has the advantages that the process is simple, the fuel can be produced from the mixture of biomass waste, kitchen waste and sludge, and the method and apparatus are easy to implement, save energy and reduce secondary pollution of environment.

Description

technical field [0001] The invention relates to the technical field of treatment of kitchen garbage, biomass waste and sludge produced by urban landscaping. Background technique [0002] By the end of 2014, a total of 3,717 sewage treatment plants had been built in cities and counties (hereinafter referred to as towns, excluding other administrative towns) nationwide, with a sewage treatment capacity of 157 million cubic meters per day, an increase of about 8 million cubic meters per day compared with 2013. day. [0003] A total of 2,107 sewage treatment plants have been built and put into operation in cities across the country, with a sewage treatment capacity of 129 million cubic meters per day, an increase of about 6 million cubic meters per day compared with 2013. [0004] With the substantial increase in sewage treatment capacity, the amount of sludge produced has also increased significantly. According to statistics, by the end of 2014, the national production of wet...
