Problems solved by technology

[0002] Composting treatment to produce organic fertilizer is the best way to dispose of solid organic waste. Composting treatment can be mainly divided into aerobic composting and anaerobic composting. The decomposition products of anaerobic composting microorganisms usually contain NH 4 、CH 4 , and other malodorous gases, causing environmental pollution. At the same time, it is easy to cause nitrogen nutrition loss and reduce the quality of compost. Therefore, most people choose aerobic composting. Aerobic composting is divided into static aerobic composting and dynamic aerobic composting. Composting, dynamic aerobic composting, on the one hand, requires a lot of equipment, on the other hand, it also needs a lot of power in the composting process, and the operating cost is high

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and implementation examples.

[0022] The invention provides a method for aerobic rapid composting of municipal domestic sludge, which is characterized in that it comprises the following steps:

[0023] (1) After the required composting and fermenting objects are mixed evenly according to the composting formula ratio, they are sent to the fermentation tank and stacked to a height of 1.2~1.5m;

[0024] (2) Blow the tail gas of the drying furnace evenly from the bottom of the pile to the pile, raise the temperature of the pile to 6~10°C, and then stop blowing the tail gas;

[0025] (3) When the stockpiling temperature exceeds 55°C, the exhaust gas of the drying furnace is evenly blown to the stockpiling from the bottom of the stockpiling;

[0026] (4) When the stacking temperature exceeds 65°C, blow the air evenly from the bottom of the stacking to the stacking, so that th...

Abstract

The invention relates to a method for aerobic quick composting of urban domestic sludge as well as a device and a using method thereof. In the invention, an air duct is installed at the bottom of a fermentation tank, and the temperature of the fermentation tank is controlled by using a draught fan, therefore, a composting treatment effect is enhanced, the compost environment is improved, the quality of a compost product is improved; and the method for aerobic quick composting of the urban domestic sludge has important meaning for promoting organic solid wastes to realize recycling of cultivated lands.

Description

technical field [0001] The invention relates to a method for rapid aerobic composting of urban domestic sludge, a device and a use method thereof, and is particularly useful for rapid and harmless treatment of organic waste. Background technique [0002] Composting treatment to produce organic fertilizer is the best way to dispose of solid organic waste.
