Description

Movable immersed biological reaction box

Technical Field

The invention relates to the technical field of biological reaction boxes, in particular to a movable immersed biological reaction box.

Background

The activated sludge process is a main method for biologically treating wastewater mainly comprising activated sludge, and is a sludge-like flocculate formed by the proliferation of aerobic microorganisms after air is continuously introduced into the wastewater for a certain period of time, on which microorganisms mainly comprising the zoogloea inhabit, and which has a strong ability to adsorb and oxidize organic substances. Under the condition of artificial oxygenation, sewage and various microbial populations are continuously mixed and cultured to form activated sludge, and the biological coagulation, adsorption and oxidation effects of the activated sludge are utilized to decompose and remove organic pollutants in the sewage. Then separating the sludge from the water, returning most of the sludge to the aeration tank, and discharging the rest of the sludge out of the activated sludge system.

The existing biochemical system is often used for solving the problem through a newly-built sewage treatment tank, the emergency of a sewage treatment plant is difficult to deal with in a short time, the sewage treatment plant is timely modified, the construction period is long, and the sewage treatment capacity is influenced.

Furthermore, the mud suction pipe is connected with a mud suction pump.

Further, the specific filler is positioned below the suspended filler.

Compared with the prior art, the invention has the advantages that: aiming at the problems that part of sewage treatment plants or sewage treatment stations are difficult to bear the change of water quality and water quantity in a short time due to early design, so that part of biochemical indexes have the risk of exceeding the standard;

the pretreatment capacity of a regulating reservoir or a reservoir in a part of sewage treatment plants or sewage treatment stations is improved, pretreatment is carried out under the condition that the space of the regulating reservoir or the reservoir is not occupied, and simultaneously mud is easy to accumulate at the bottom of the regulating reservoir or the reservoir due to the operation problem;

the manufacturing period is short, and the processing and the dismounting are convenient; the device can be quickly put into use, the pollutant removal rate is improved, and the operating pressure of the conventional biochemical tank is relieved; the aeration time and the air quantity are automatically adjusted by adopting an automatic control dissolved oxygen technology; the technical advantages of the biomembrane reaction bed are combined, the defect of heavy civil structure is overcome, and the treatment capacity of a sewage treatment plant can be effectively improved; the regulating reservoir or the reservoir of a sewage treatment plant or a sewage treatment station is utilized, no additional modification is needed, the cost is low, and the effect is quick; the sewage treatment system is integrated with manufacturing, modular design and automatic control, and realizes unattended sewage treatment.
