An underground stuffy pool structure for physical purification of domestic sewage

Abstract

The invention discloses an underground stuffy pool structure for physical purification of domestic sewage, comprising a sewage pool, a cutting knife is arranged on the outer side of the turntable, a stirrer is installed on the bottom of the turntable, an electromagnetic heating coil is arranged on the inner wall of the heating chamber, and an air inlet fan and An oxygen-enriched membrane is arranged between the air pipes, the water pump and the sedimentation chamber are connected through a connecting pipe, and a filter screen is arranged between the connecting pipe and the sedimentation chamber. The invention drives the turntable to rotate by the drive motor through the rotating rod, which facilitates the high-speed rotation of the cutting knife on the outside of the turntable and the agitator at the bottom of the turntable, prevents the stains in the sewage from clogging the water inlet pipe, and improves the stains in the sewage by raising the temperature. Decomposition rate, improve sewage purification efficiency, make sewage purification more comprehensive, and through the input of oxygen, domestic sewage can be separated from oil and water, and it can also accelerate the rapid reproduction of aerobic microorganisms in the sedimentation chamber in an oxygen-enriched environment, improve the decomposition rate, and more Facilitate the discharge of sewage.

Description

technical field [0001] The invention relates to the field of sewage treatment and purification, in particular to an underground stuffy pool structure for physical purification of domestic sewage. Background technique [0002] Domestic sewage is the wastewater discharged in the daily life of residents, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets, etc. The pollutants contained in domestic sewage are mainly organic matter ( Such as protein, carbohydrate, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infection virus, etc.), the organic matter existing in domestic sewage is extremely unstable, easy to rot and produce stench, bacteria and pathogens The large-scale reproduction of organic matter in domestic sewage as nutrition can lead to the spread of infectious diseases. Therefore, domes...

[0002] Domestic sewage is the wastewater discharged in the daily life of residents, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets, etc. The pollutants contained in domestic sewage are mainly organic matter ( Such as protein, carbohydrate, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infection virus, etc.), the organic matter existing in domestic sewage is extremely unstable, easy to rot and produce stench, bacteria and pathogens The large-scale reproduction of organic matter in domestic sewage as nutrition can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge. In general, during the treatment of domestic sewage, impurities in domestic sewage and large particle stains will affect the water pipes. Cause blockage, resulting in low sewage purification efficiency, and domestic sewage contains a large amount of oil stains mixed with water, which is difficult to separate, increasing the cost of sewage purification
