Description

Technical Field

[0001] The utility model belongs to the technical field of novel rural sewage purification tanks, and more specifically, particularly relates to a novel rural sewage purification tank. Background Art

[0002] According to statistics, my country has over 19,000 administrative towns, over 600,000 administrative villages, and over 2.5 million natural villages (collectively referred to as villages and towns), accounting for approximately 55% of the country's total domestic sewage discharge. The sources of sewage in villages and towns are dispersed, making centralized treatment difficult. This requires localized treatment through the construction of small-scale sewage treatment facilities (processing a few to several thousand tons per day). Currently, the domestic sewage treatment rate in my country's villages and towns is very low, making it a significant source of pollution in regional water environments. This is primarily due to the low investment in sewage treatment facilities in villages and towns, but more importantly, the existing decentralized sewage treatment processes are not suitable for China's national conditions, resulting in a very low rate of normal operation of existing sewage treatment facilities.

[0003] When using the current new rural sewage purification tank, it needs to be buried in the ground and connected to the corresponding sewage pipe for use. It is used to purify rural domestic sewage to protect the environment. However, rural sewage often contains some solid impurities. For example, water used for washing vegetables and rice is often mixed with rice grains or vegetable leaves and fruit peels and other impurities. When these impurities enter the purification tank with the sewage, it is easy to cause blockage of the purification tank, resulting in the inability of the purification tank to treat the sewage normally.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a new type of rural sewage purification tank is provided in order to achieve a more practical purpose. Utility Model Content
