Description

Aeration pipe for sewage treatment

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to an aeration pipe for sewage treatment.

Background

Aeration is one of the common methods in the sewage treatment industry, and the organic matters in the sewage are subjected to oxidative decomposition reaction by introducing air into the sewage to contact microorganisms and dissolved oxygen, and the dissolution speed of oxygen in the air and the sewage is accelerated due to the stirring effect of the air, so that the oxygenation purpose is achieved.

The aeration technology mainly comprises compressed air aeration, mechanical aeration, jet aeration and other modes. The compressed air aeration is a common aeration mode, compressed air is generated by an air compressor and is conveyed to an aerator arranged in water through a pipeline, so that the air contacts with water as much as possible, and oxygen in the air is dissolved in sewage. At present, when compressed air aeration is adopted in some sewage treatment, an aeration hose is required to be laid at the bottom of a tank, and compressed air is discharged into sewage through an air outlet slot arranged on the aeration hose, so that aeration is realized. After compressed air is introduced into the aeration hose, the air outlet slot is opened under the action of air pressure, so that air smoothly enters water to form aeration. And, because the air outlet seam is formed by cutting, along with the air pressure reduction, the air outlet seam is recovered to be closed under the elastic action of the aeration hose, thereby avoiding suspended matters in sewage from entering the pipe.

However, the aeration mode has the defects in the actual use process, mainly characterized in that the air pressure generated by an air compressor is unstable and can fluctuate within a certain range, for example, the opening and closing of other air utilization equipment can influence the air pressure, the thickness and the strength of an aeration hose are uneven, and the bearing capacity on the pressure is also different, so that the aeration hose can have the effects of the unstable air pressure, a part of air outlet gaps are widened, and the other part of air outlet gaps are narrowed, so that the aeration is uneven, and the speed of oxygen dissolved in sewage is greatly reduced; in addition, the service life of the aeration hose is short, and the local pressure of the aeration hose is increased suddenly and the deformation is increased along with the increase of the air outlet of the air compressor, so that the probability of bursting of the aeration hose is greatly increased, the aeration device is disabled, and the operation is stopped.
