Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass septic tanks, specifically a fiberglass septic tank with anti-backflow odor. Background Technology

[0002] A septic tank is a device for treating and filtering feces. Its principle is that solids decompose at the bottom of the tank, while the upper layer of water flows away through pipes, preventing blockages and allowing sufficient time for the solids (feces and other waste) to hydrolyze. A septic tank refers to a structure that separates and settles domestic sewage and anaerobically digests sludge. Traditional septic tanks are made of brick and mortar, requiring on-site construction, which results in long construction periods, large land areas, and high costs. Furthermore, most traditional septic tanks suffer from numerous problems in design, construction, use, and management, easily leading to leaks and groundwater pollution. To address these shortcomings of traditional septic tanks, the government is actively promoting fiberglass septic tanks, composite material products specifically designed for treating domestic sewage, which are widely used in various fields.

[0003] The existing fiberglass septic tank (CN202022890899.2) has a mixing device located at the inlet end. This device stirs and breaks down solid materials entering the fiberglass inner cylinder, reducing the occurrence of blockages. Simultaneously, the mixing device stirs the incoming sewage or feces, ensuring rapid and uniform mixing, further improving fermentation efficiency and effect. However, it has shortcomings: the existing equipment has poor backflow prevention, and parts replacement is inconvenient, resulting in unsatisfactory performance. Therefore, a fiberglass septic tank with backflow prevention is needed to solve these problems. Utility Model Content
