Rural domestic sewage treatment modular equipment

Abstract

The invention relates to the technical field of domestic sewage treatment equipment, and discloses rural domestic sewage treatment modular equipment which comprises a primary sedimentation tank, a biochemical treatment tank arranged on one side of the primary sedimentation tank, a pre-filtration treatment tank arranged in the biochemical treatment tank, and a purification and disinfection tank arranged on one side of the biochemical treatment tank. A water inlet pipe is arranged at the top of the primary sedimentation tank, a first motor is arranged on the outer wall of one side of the primary sedimentation tank, a first rotating shaft is arranged at one end of the first motor, propellers are arranged on the periphery of the first rotating shaft, a sludge suction pump is arranged at the bottom of the primary sedimentation tank, and sludge tanks are arranged at the bottoms of the biochemical treatment tank and the purification and disinfection tank. According to the rural domestic sewage treatment modular equipment, manual maintenance and use are facilitated, the situation that soil and dust are hardened at the bottom of the tank due to the fact that the soil and dust are not discharged in the primary tank for a long time is avoided by arranging a spiral stirring structure, and later maintenance and replacement are facilitated due to the fact that the filtering structure is adjustable.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment equipment, in particular to a modular equipment for treating domestic sewage in villages and towns. Background technique [0002] Water pollution treatment has been widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc. In order to make the sewage discharge meet the corresponding indicators, it is necessary to carry out corresponding water pollution treatment procedures for sewage, and at the same time , Water pollution treatment is also increasingly entering the daily life of ordinary people. [0003] Domestic sewage in villages and towns includes all kinds of washing water, sewage and feces in daily life. Most of them are non-toxic inorganic salts with relatively fixed components. They mainly contain organic matters such as carbohydrates, proteins, amino acid...

AI Technical Summary

Problems solved by technology

[0005] The existing domestic sewage treatment equipment in villages and towns is generally buried, but because the dirt and dust in villages is much larger than that in cities and towns, the dirt and dust will settle in the primary sedimentation tank, and if the dirt and dust are not discharged for a long time, they will be in the pool. Hardening occurs at the bottom, which affects the sedimentation and use of the primary tank, and because the buried type is inconvenient for manual maintenance and use, and the filter structure in the existing sewage treatment device is generally fixedly installed in the sewage tank, it is not convenient for later maintenance and replacement, affecting Subsequent sewage treatment effect
