Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of self-cleaning septic tanks, and in particular relates to a self-cleaning septic tank. Background Art
[0002] Traditional septic tanks originated in Europe in the late 19th century, with a history of more than 200 years. They began to be widely used in my country in the 1970s and 1980s. The septic tanks currently used in my country have always used the traditional three-stage structure, mainly using the principle of natural sedimentation and anaerobic fermentation technology to perform anaerobic digestion of human and animal feces. They are primary facilities for domestic sewage treatment, mainly used to remove suspended organic matter in sewage, prevent pipe blockage, and achieve harmless treatment of feces. Generally, septic tanks need to use suction trucks to clean the settled sludge every 3-9 months, but the suction capacity of general suction trucks is often limited, especially for dry and compacted solid sludge. In practice, it can only be diluted with a large amount of clean water, resulting in high cleaning costs. Therefore, it is necessary to design a new type of septic tank with self-cleaning and purification capabilities.
[0003] Since 2013, my country's Ministry of Construction has promulgated the "Regulations on Urban Drainage and Sewage Treatment," implementing a drainage permit system. This mandates that any wastewater discharger must meet required discharge standards and obtain a drainage permit before discharging wastewater into the municipal network. However, traditional septic tanks, due to their low design payload and poor treatment efficiency, are no longer able to meet my country's current requirements for meeting wastewater discharge standards in the face of increasingly complex wastewater discharge conditions.
[0004] Based on the above analysis, it is imperative to design a new type of high-efficiency septic tank with certain self-purification capabilities (or to transform traditional septic tanks). This product technology utilizes the self-purification principle of water bodies that is prevalent in nature, and uses modern bionic biological technology to accelerate the self-purification process of water bodies, and designs a self-cleaning septic tank purification product that is in line with my country's national conditions.

[0025] It should be noted that while traditional septic tanks originated in Europe in the late 19th century, dating back over 200 years, they began to be widely used in my country in the 1970s and 1980s. Septic tanks currently used in my country still utilize a traditional three-stage structure, primarily utilizing natural sedimentation and anaerobic fermentation to anaerobic digest human and animal feces. They are primary facilities for domestic sewage treatment, primarily used to remove suspended organic matter from sewage, prevent pipe blockages, and achieve harmless treatment of feces. Typically, septic tanks require suction trucks to clean out settled sludge every 3-9 months. However, these trucks often have limited suction capacity, especially for dry, compacted solid sludge, which can only be diluted with large amounts of clean water, resulting in high cleaning costs. This solution, by installing a preliminary treatment tank 1, a filling and filtering tank 2, a mixing and stirring tank 3, and a sterilization and disinfection tank 4, breaks up large pieces of solid waste to prevent large particles of domestic waste from clogging the pipes. Septic tank water that fills filter tank 2 enters mixing and stirring tank 3, where it mixes with oxygen, ozone, and the water to maintain a certain level of dissolved oxygen and water activity. This further reduces odor, color, and oil content in the water, as well as high concentrations of COD, nitrogen, phosphorus, and organic matter. It also kills a large number of bacteria and other microorganisms in the water, thereby cleaning the water and restoring its self-purification capacity, ensuring that the wastewater meets the specified inlet standards for municipal sewage treatment plants. This solution addresses the inconveniences of manual oil removal, odor removal, and slag removal. It is practical, efficient, and durable, making it an ideal replacement for traditional septic tanks.
