Abstract

PURPOSE: A fermentation process of food waste is preferably provided to mass produce good quality of compost and feed by fermenting food waste or excretions from livestock breeding with aerobic bacteria. CONSTITUTION: A fermentation and composting process of food waste is performed by introducing aerobic thermopile into the waste, together with air and heating source to ferment the waste. During fermentation process, fermentation heat is generated and used for the process. Microorganisms and promotor or catalyst can be added to the process and particularly, the catalyst stimulates bacteria to alter sodium ions and to make gaseous chlorine in food waste to be discharged outside. The aerobic fermenting stage is continued for 3-7 days followed by ageing stage for 3-7 days.

Description

A food refuse for fermentation and coposting the waste water and device

The present invention relates to a method and apparatus for fermenting and composting food waste, while producing high quality compost and feed by fermenting livestock manure and food waste with moisture regulators (sawdust, rice husk, rice bran, rice straw) and microorganisms and microbial catalysts. The present invention relates to a method and apparatus for fermenting and composting food waste, which completely prevents environmental pollution by non-discharge treatment.

An object of the present invention is to provide a method and apparatus for fermenting and composting food waste, which economically treats a large amount of food waste livestock manure and prevents environmental pollution by non-discharge treatment.

Food waste fermentation and composting method according to the present invention for achieving the above object is

① A passage tube should be prepared so that microbial and microbial promoter forming solution can be sprayed into the aging tank.

② Sprinkle water and food waste in the storage tank with a water conditioning agent (sawdust, rice husk, rice bran, rice straw).

③ Make a hole by attaching a band heater to the air supply nozzle. It consists of fermentation tank, ripening tank, broa, and transfer means that can stack feed and compost materials at a certain height.

1 is a flow chart illustrating a method of fermentation and composting of food waste according to the present invention, consisting of a storage tank, a microorganism and a microbial catalyst formation tank and watering, and a waste water mixture in a moisture control agent, aerobic fermentation (adding heat source), and aerobic ripening. The order is as follows.

First, the low temperature, mesophilic and high temperature bacteria are mixed with the catalyst and sprayed on the bottom of the fermenter.

Second, buy a food waste, livestock manure, and make the water content of a mixture of water adjuster (rice bran, rice hulls, sawdust, straw) to the fermentor to 60% ^to 70%.

Third, the height of the fermentation tank is about ^3-4 m and air is injected into the bottom of the fermenter using an air supply fan and an air supply nozzle to maintain aerobic fermentation. At this time, the band heater is fixed at 80 degrees and indirect heat source is maintained at 60 degrees thermophilic bacteria and radiation germs to ferment for 4 ^to 8 hours. Thereafter, the fermentation process is naturally performed for 3 ^to 7 days by the main nutrients and organic matter containing organic wastewater in the temperature, humidity, air and C / N ratio.

Fourth, it is installed in the transfer tank to be matured by injecting the bottom of the tank for 1 hour a day using an air fan and an air supply nozzle. Aging for one week in aerobic state.

After packing can be shipped.
