Ecological septic tank

Abstract

The invention discloses an ecological septic tank, comprising a septic tank body. A fermentation tank, a decomposition tank and a digestion tank are arranged sequentially from left to right in the septic tank body. The upper left corner of the fermentation tank is provided with a feces inlet, the upper right corner of the fermentation tank is provided with a feces outlet, the upper portions of the fermentation tank, decomposition tank and digestion tank are each provided with a clearing port, the fermentation tank and the decomposition tank are communicated through a first feces pipeline, an opening of the first feces pipeline is provided with a strainer, the strainer includes a fine asbestos mesh layer, a stainless steel mesh layer is arranged on the right of the fine asbestos mesh layer, the decomposition tank and the digestion tank are communicated through a second feces pipeline, an opening of the second feces pipeline is provided with a filter cover, the filter cover includes a compressive foam layer, an active carbon layer is arranged in the compressive foam layer, and a support mesh is disposed in the active carbon layer. The ecological septic tank is simple in structure, is effective in preventing blockage, helps treat feces and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of excrement treatment devices, in particular to an ecological septic tank. Background technique [0002] A septic tank is a device for treating feces and filtering sediment. The principle is that the solidified matter decomposes at the bottom of the pool, and the hydrated objects on the upper layer enter the pipeline to flow away, preventing the pipeline from being blocked, and giving the solidified objects (feces and other garbage) enough time to hydrolyze. Grid sedimentation, and small treatment structures for anaerobic digestion of sludge. [0003] The existing septic tanks have poor treatment effect, prone to incomplete fermentation, and easy to block pipelines. The suspended solids retained in the septic tank undergo anaerobic decomposition to generate some organic acids, ammonia, carbon dioxide and hydrogen sulfide, resulting in sewage Germs, viruses, and organic matter cannot be completely fermented and deco...

[0003] The existing septic tanks have poor treatment effect, prone to incomplete fermentation, and easy to block pipelines. The suspended solids retained in the septic tank undergo anaerobic decomposition to generate some organic acids, ammonia, carbon dioxide and hydrogen sulfide, resulting in sewage The acidification and odor of bacteria, viruses, and organic matter cannot be completely fermented and decomposed, and the odor spreads and spreads diseases, endangering people's health
