Shock absorber of air pressure and air supplying system using the same applied in the biological process for sewage treatment system

摘要

The present invention relates to an air supply system applied to a biological treatment method of sewage and wastewater, and more particularly, to supply air for supplying necessary air in an aeration tank for activating microorganisms to remove contaminants contained in sewage and wastewater and sewage. In the system, by attenuating or removing the impact energy of the blower due to the blower's deterioration or self-defect, and the pulsation of the pulsation caused by the blower's intermittent operation, the amount of air discharged from the various diffusers can be kept uniform. In addition to maximizing treatment efficiency, it prevents damage to the connections of the diffuser by impact energy, thereby maximizing the lifetime of the diffuser, thereby reducing maintenance costs and preventing wastewater discharge from abnormal operation. The present invention relates to an air supply system applied to a treatment method.;The present invention comprises an aeration tank having a predetermined size, a plurality of diffusers installed on the bottom of the aeration tank, a plurality of blowers installed on the outside of the aeration tank, and the air configured to communicate the plurality of blowers and the diffuser pipes In the supply system, a blower or air transfer is provided on the air conveying pipe by installing an air pressure buffer including an expansion pipe having a predetermined length having a larger diameter than that of the air supply pipe. It is characterized in that to absorb and buffer the fluctuations in air pressure and impact energy generated in the pipe.
