Circulating sludge biological fermentation tank, processing system and processing method

Abstract

The invention discloses a circulating sludge biological fermentation tower which comprises a tower body, an openable tower cover, a storage tank and a plurality of rotatable fermentation devices, wherein the openable tower cover is arranged on the top of the tower body; the storage tank is arranged at the bottom of the tower body; the rotatable fermentation devices are arranged in the tower body in parallel; the fermentation devices divide an inner cavity of the tower body into a plurality of layers of fermentation bins along the axial direction; the lower part of each layer of fermentation device is provided with a ventilating oxygen supply pipeline communicated with a blower; the upper part of each layer of fermentation device is provided with an air outlet pipeline communicated with aninduced draft fan and a monitoring device; the monitoring device is controlled by a control room; and a mechanism for driving the fermentation devices and the tower cover to move, the blower and the induced draft fan are all controlled by the control room. The invention also discloses a circulating sludge biological processing system and a processing method. By the circulating sludge biological fermentation tower, the circulating sludge biological processing system and the processing method, industrial biological fermentation desiccation treatment can be continuously and stably carried out onsludge under the conditions of high efficiency and low energy consumption.

Description

technical field [0001] The invention relates to equipment for industrialized biological drying treatment of sludge, in particular to equipment and a treatment method for biological fermentation and drying of sludge capable of realizing a continuous cycle fermentation process. Background technique [0002] Urban sludge not only has a high water content, but also contains organic substances, heavy metals, nitrogen and phosphorus, pathogenic microorganisms and parasite eggs, which is perishable and emits a strong odor. If it is not treated effectively, it will damage the environment and pollute the soil and water bodies, endangering human health. The conventional disposal methods of sludge mainly include incineration, landfill, composting and throwing into the sea. Incineration disposal is not only limited by technology and equipment, but also consumes a lot of energy and costs, and will cause air pollution; the landfill method is affected by site and environmental conditions;...
