Description

Technical Field

[0001] This utility model relates to the field of domestic sewage treatment technology, specifically a fermentation device for the disposal of rural domestic sewage. Background Technology

[0002] Rural domestic sewage typically includes kitchen wastewater, bathroom wastewater, toilet wastewater, and livestock and poultry breeding wastewater. Direct discharge of this sewage can lead to pollution of surface water and groundwater. Since domestic sewage contains a large amount of organic matter, it can be decomposed into simple compounds such as methane, carbon dioxide, and water through fermentation, thereby reducing the organic matter content in the sewage.

[0003] The publication number CN118724282A discloses a biological fermentation treatment device for rural domestic sewage, which includes: a sewage tank for storing sewage for fermentation; and a filter box located outside the sewage tank, wherein the filter box is provided with a filter structure inside.

[0004] The aforementioned fermentation treatment equipment can treat wastewater with both aerobic and anaerobic processes, and can also use aquatic plants for wastewater treatment. However, when discharging wastewater after fermentation, various large impurities remain in the wastewater, making it inconvenient to filter them during discharge, which affects subsequent treatment processes. Furthermore, the impurities in the wastewater tend to accumulate and adhere to the inner wall of the tank over a long period of time, making it inconvenient to automatically scrape and clean them. Utility Model Content

[0005] The purpose of this invention is to provide a fermentation device for the treatment of rural domestic sewage, so as to solve the technical problems in the background art.
