Novel digestion cell device capable of lowering sludge discharge

Abstract

The invention relates to digestion cell devices, in particular to a novel digestion cell device capable of lowering sludge discharge. The novel digestion cell device comprises a digestion cell body which is of a tetragonal structure, and a plurality of activated sludge flow-in pipelines are arranged on the upper portion of the outer surface of the left side wall of the digestion cell body; an aeration device is arranged in the middle of the inside of the digestion cell body, and a plurality of activated sludge output mechanisms are arranged in the middle of the outer surface of the right sidewall of the digestion cell body; the bottom of the digestion cell body is of an arch-shaped structure with the middle higher and two ends lower, a sludge discharging mechanism for scraping sludge along the bottom of the digestion cell body is arranged on the inner side wall of the digestion cell body, and a plurality of residual sludge discharging pipelines are arranged at the bottom of the outerside wall at each of the left and right ends of the digestion cell body. The novel digestion cell device can provide friendly sludge treatment environment for microorganisms, is sufficient in aerationand can lower the sludge discharge.

Description

Technical field [0001] The invention relates to a digestion tank device, in particular to a novel digestion tank device for reducing sludge discharge. Background technique [0002] With the development of economy, people’s requirements for sewage treatment are getting higher and higher. Traditional process treatment adopts the method of adding chemical materials for sewage treatment. During this period, a large amount of chemical sludge waste will be produced, which has serious odor and chemical pollution. Mud waste also caused secondary pollution of the environment. [0003] In order to solve the large-scale production of chemical sludge waste, the current industry is developing towards the direction of treating wastewater with microorganisms. The amount of sludge produced by treating wastewater with microorganisms will be drastically reduced. However, while the process of treating wastewater with microorganisms is developing, the conventional use is still The digestion tank devi...

Problems solved by technology

[0002] With the development of the economy, people have higher and higher requirements for sewage treatment. Traditional process treatment uses the method of adding chemical materials for sewage treatment, during which a large amount of chemical sludge waste will be produced, the odor is serious, and the chemical pollution produced Mud waste also causes secondary pollution to the environment

[0003] In order to solve the large amount of chemical sludge waste, the industry is currently developing towards the use of microorganisms to treat wastewater, and the amount of sludge produced by using microorganisms to treat wastewater will be greatly reduced. However, while developing towards the use of microorganisms to treat wastewater, conventional methods are still The digestion tank device used in the traditional chemical process cannot meet the technological requirements of using microorganisms to treat wastewater. Its aeration is insufficient, and the effect of microbial sludge treatment is not friendly to the environment, which limits microbial sludge treatment and reduces the amount of sludge produced. The effect is reflected without processing
