Buffer tanks for hydrolysis of small particulate organic waste

Abstract

The invention relates to a buffer pool for the hydrolysis of small-granular organic wastes. The buffer pool comprises a first-level buffer pool, a second-level buffer pool and a third-level buffer pool, wherein the first-level buffer pool and the second-level buffer pool are used for storing organic wastewater, the third-level buffer pool is used for carrying out the hydrolysis on the organic wastewater, the first-level buffer pool and the second-level buffer pool are connected by a separating wall, an electric gate valve is arranged on the separating wall, the bottom of the second-level buffer pool is provided with a submersible sewage pump, the submersible sewage pump is connected with the third-level buffer pool by a pipeline, and a heat supply device is arranged in the third-level buffer pool; and the volume of the second-level buffer pool is greater than the wastewater quantity produced by an organic wastewater source in the hydrolysis cycle of the organic wastewater. According to the buffer pool, due to the arrangement of the three levels of buffer pools, the first-level buffer pool and the second-level buffer pool can be used for storing and accommodating the newly produced wastewater, and the third-level buffer pool can be used for carrying out the hydrolysis on the organic wastewater, so that the newly produced wastewater can be separated from the wastewater which is being hydrolyzed, so that the sufficient hydrolysis of the organic wastewater is ensured, and the effect of late anaerobic digestion is ensured.

Description

Technical field

[0001] The invention relates to the field of energy and environmental protection, in particular to a buffer tank used for the hydrolysis of small particle organic waste. Background technique

[0002] At present, the use of anaerobic fermentation technology to treat organic waste such as kitchen waste and organic waste is widely used. After the organic waste is broken into small particles by the crusher, the organic matter needs to be hydrolyzed to prepare for the subsequent anaerobic digestion of the organic matter. Therefore, it is necessary to design a buffer pool to allow these small organic matter to complete the hydrolysis process. At present, a buffer tank is generally used to complete the process of storing and hydrolyzing organic wastewater. However, since the hydrolysis of organic substances requires a certain period of time, during the hydrolysis process, new wastewater is constantly entering, so the newly entered wastewater has been hydrolyzed for a per...
