Embodiment 1

[0049] The continuous dynamic aerobic fermentation treatment system for organic waste provided in this embodiment can treat municipal solid waste, such as treating dewatered sludge produced in a sewage treatment plant, so that the treated sludge meets the stabilization requirements.

[0050] Such as figure 1 As shown, the system includes: auxiliary silo 1, organic waste silo 2, conveyor 3, mixer 4, mixing silo 5, aerobic fermentation drum 6, first fan 7, second fan 12, waste gas treatment Tower 8, screening machine 9, online detector 10 and control subsystem 11;

[0051] Among them, the conveyor 3 is connected to the auxiliary silo 1 and the organic waste silo 2 respectively. The discharge of the auxiliary silo 1 and the organic waste silo 2 is connected to the mixing silo 5, the aerobic fermentation drum 6 and the screening machine in turn through the conveyor. 9 connections;

[0052] The aerobic fermentation drum 6 is a fully enclosed external rotary fermentation drum. Through the...

Embodiment 2

[0066] This embodiment provides a continuous dynamic aerobic fermentation treatment system for organic waste. The system structure is basically the same as the system given in the first embodiment above. The difference is that a crushing device is provided in the auxiliary silo 1 and the organic waste silo 2. , The crushing device can crush the reprocessed domestic garbage after screening.

[0067] Use the above aerobic fermentation system to ferment the municipal solid waste, and place the municipal solid waste fully mixed with the fermentation auxiliary materials and part of the fermentation materials in the auxiliary silo 1 and the organic waste bin 2 for temporary storage, and pass the conveyor 3 The organic waste and auxiliary materials in the auxiliary silo 1, the organic waste silo 2 are sent to the mixing silo 5 for mixing by the mixer 4, and the mixed materials are temporarily stored or passed through the mixing silo 5. The conveyor 3 is transported to the aerobic fermen...

Embodiment 3

[0070] This embodiment provides a continuous dynamic aerobic fermentation treatment method for organic waste, which can treat municipal solid waste so that the treated product meets the stabilization requirements. Such as image 3 As shown, the method is a method of using the organic waste continuous dynamic aerobic fermentation treatment system of the foregoing embodiment 1 or embodiment 2, and includes the following steps:

[0071] Under the control of the control subsystem of the treatment system, the conveyor of the treatment system preprocesses the organic waste through the pretreatment subsystem of the treatment system;

[0072] The pretreated organic waste is transported by a conveyor to the aerobic fermentation drum for fermentation treatment, and the material after the fermentation treatment is output;

[0073] The control subsystem of the processing system controls the operation status of each device to complete the continuous dynamic aerobic fermentation treatment of orga...

Abstract

The invention discloses a treatment system and a treatment method for continuous dynamic aerobic fermentation of organic waste. In the system, a pretreatment part comprises an auxiliary storage bin, an organic waste bin, conveyors, a mixer, a mixing bin and a sieving machine, and the moisture adjustment, nutritive ratio proportionment, mixing, storage and sieving of the organic waste are achieved. An aerobic fermentation roller is a totally-closed external-rotation fermentation roller; the charging and discharging are accomplished by the conveyors; and the air supply and waste gas treatment are conducted by fans and a waste gas treatment tower. A control subsystem immediately adjusts operating conditions of the aerobic fermentation roller and the pretreatment part by monitoring parameters fed back by an on-line detector on the aerobic fermentation roller to achieve the continuous, dynamic and steady operation and timely condition correction of the whole system; the treatment efficiency is improved greatly; the fermentation time is shortened; a treatment effect is improved; and the harmless and resourceful treatment of the organic waste such as sludge, garbage and kitchen waste can be achieved.

Description

Technical field [0001] The present invention relates to the field of urban organic waste treatment, in particular to a continuous dynamic aerobic fermentation treatment system and method for organic wastes for processing urban organic wastes such as dewatered sludge, domestic waste, kitchen waste and the like of urban sewage treatment plants . Background technique [0002] With the acceleration of my country’s economy and urbanization, cities have produced a large amount of urban organic waste, such as dewatered sludge from urban sewage treatment plants, household waste, kitchen waste, garden waste, etc., which have caused "garbage siege" and "garbage siege". "Sludge dumping" and other phenomena. According to incomplete statistics, in 2010 alone, 100 million tons of domestic waste (including 60 million tons of food waste) and 30 million tons of dehydrated sludge were generated. These pollutants contain high levels of organic matter, including parasite eggs, pathogenic microorgan...
