Embodiment 1

[0065] For example, in one embodiment according to the present disclosure, when using the sludge aerobic fermentation drum equipped with the air supply system of the above-mentioned organic waste aerobic fermentation drum to perform aerobic fermentation on the dewatered sludge produced by the municipal sewage treatment plant , divide the fermentation drum into 3 functional areas, configure 3 sets of air supply subsystems and 4 air supply main pipes. Each independent gas supply subsystem contains a set of online monitoring system (such as an integrated oxygen concentration and temperature detector), varying numbers of aerators, a gas supply branch pipe regulating valve, a gas supply main pipe regulating valve, And the corresponding gas supply pipeline 5, etc.; the online monitoring instrument passes through the barrel of the aerobic fermentation drum, monitors the real-time data of the fermentation process of the organic waste in the barrel and sends it to the controller. The c...

Embodiment 2

[0068] This embodiment provides an air supply system for the aerobic fermentation drum of organic waste. The structure of the system is basically the same as that given in the first embodiment above. Air sub-system and 6 air supply pipes.

[0069] The sludge aerobic fermentation drum of the above-mentioned organic waste aerobic fermentation drum air supply system is used to ferment municipal solid waste. The fermentation drum is divided into 4 functional areas, equipped with 4 sets of air supply subsystems and 6 Air supply mains. Each independent gas supply subsystem contains a set of online monitoring system (such as an integrated oxygen concentration and temperature detector), varying numbers of aerators, a gas supply branch pipe regulating valve, a gas supply main pipe regulating valve, And the corresponding gas supply pipeline, etc.; the online monitoring instrument passes through the barrel of the aerobic fermentation drum, monitors the real-time data of the fermentation...

Abstract

The invention discloses an air supplying system and an air supplying method for an organic waste aerobic fermentation roller. The air supplying system comprises a fan, an air supplying pipeline, an air distributing device, a monitoring device and a controller, wherein the air supplying pipeline is divided into an air supplying main pipe and an air supplying branched pipe, a main pipe adjusting valve is arranged on the air supplying main pipe and a branched pipe adjusting valve is arranged on the air supplying branched pipe; the air distributing device is arranged at the end of the air supplying branched pipe; the monitoring device is provided with a sensor arranged in the aerobic fermentation roller; the air supplying system supplies air to multiple functional divisions in the fermentation roller, the monitoring device is arranged in at least one functional division of multiple functional divisions in the aerobiotic roller, and the controller controls at least one of the main pipe adjusting valve, the branched pipe adjusting valve, the air distributing device and the fan according to the data detected by the monitoring device, and the air is supplied to the corresponding functional division as required. The invention also provides an air supplying method of the air supplying system.

Description

technical field [0001] The invention relates to the field of urban organic waste treatment, in particular to an air supply system for an aerobic fermentation drum of organic waste for treating urban organic waste such as dewatered sludge, domestic waste, and kitchen waste in urban sewage treatment plants and method. Background technique [0002] With the improvement of urban residents' living standards and the rapid advancement of urbanization, people's living standards have gradually developed from well-to-do to wealthy. Urban organic waste (such as dewatered sludge from urban sewage treatment plants, domestic waste, kitchen waste, garden waste, etc.) ) has also increased with the rapid economic growth, the harmless treatment and resource utilization of urban organic waste has become an environmental issue that people are increasingly concerned about, and it has also become an urgent issue for the government to solve. Since the aerobic fermentation technology can make full...
