Ecological energy-saving septic tank

Abstract

An ecological energy-saving digestion tank consists of head sewage well, anaerobic pool, anaerobic filtering pool, oxidizing channel and ecological pond. Head sewage well is arranged on the top of anaerobic pool and communicated with anaerobic pool, plunge pool is set on the top of anaerobic filtering pool, and sludge pipe is inserted in head sewage well. It achieves lower environmental pollution and energy saving.

Description

technical field [0001] The invention belongs to a septic tank, in particular to an ecological energy-saving septic tank. Background technique [0002] The treatment of fecal sewage with septic tanks has a history of more than one hundred years. Septic tanks are also called septic tanks. Initially, septic tanks were used as a feces interception facility to avoid pipeline blockage. The positive effect has continued until now and is still widely used. Its functions are also constantly improving and changing. The septic tank can store and anaerobically digest the sludge that settles at the bottom of the tank, and concentrate the sludge, which is convenient for sludge cleaning and treatment, and plays a role in protecting the environment to a certain extent. effect. my country's newly released national water supply and drainage standard atlas 02S701 and 03S702 can prove that septic tanks still play a huge role in my country's current situation.

AI Technical Summary

Problems solved by technology

[0005] (1) After being treated in a septic tank, the sewage is acidic, contains some impurities and has a foul smell. When it is cleaned up, the stench is suffocating, which affects environmental sanitation and is prone to biogas poisoning accidents. Residents have great opinions

[0006] (2) The construction of the septic tank fails to meet the design requirements, resulting in poor treatment effect

The sewage treated by the septic tank is directly discharged into the water body, causing the water source to become black and smelly, and the water outlet forms a stinky pond. In summer, mosquitoes and flies are born, and sometimes the suspended solids discharged from the septic tank can be seen with the naked eye, seriously polluting the environment

Some septic tanks are seriously leaking, polluting groundwater

[0007] (3) The facilities are scattered and the daily management is not in place. As a result, the septic tank has been cleaned by no one for a long time, and the sludge is accumulated at the bottom of the tank. The effective volume of the septic tank is gradually decreasing. At the same time, the accidents caused by the septic tank continue, such as the gas in the tank is sprayed out to burn the human body, and the explosion occurs when the manure is sucked; the workers suffocate and die when they go to the tank to clear the slag, etc.

[0008] (4) The sewage treated by the septic tank enters the centralized sewage treatment plant, resulting in insufficient microbial nutrients in the secondary biochemical treatment, inhibiting the reproduction of biochemical bacteria, and reducing the use effect
