Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] An upflow circulating aerobic aeration system. The upflow circulating aerobic aeration system includes an anoxic tank and an aerobic aeration tank; The aeration tank is divided into an upflow end and a downflow end, wherein an aeration device is provided at the upflow end, and a weir is provided at the bottom of the barrier; the aeration device includes a blower and a jet aerator, and the water outlet of the anoxic tank It is pumped to the jet aerator; the aerobic aeration tank is a two-stage aerobic aeration tank, and the two-stage aerobic aeration tank is connected through the weir at the bottom, and each aerobic aeration tank is equipped with The block divides the two-stage aerobic aeration tank into four sections, and the upflow end and the downflow end are arranged at intervals; the aeration device is arranged at the upflow end of the aerobic aera...

Abstract

The invention discloses an up-flow circulating aerobic aeration system which comprises an aerobic aeration tank and aeration devices, the aerobic aeration tank is divided into two stages, and the aeration devices are mounted in the two stages of aerobic tanks; and each aeration device comprises an air blower and a jet aerator, when the jet aerator is used for aeration, the density of the end where the aerator is located is far lower than that of the other end of the block, the density difference pushes water flow at the aeration end to rise and water flow at the other end of the block to fall, and water flow circulation is formed through a water passing weir at the bottom of the tank. By changing the structure of the aeration tank and the positions of the aeration devices, the oxygen utilization rate in the aeration tank is increased, the mixing effect of activated sludge and wastewater is improved, and the use energy consumption of the aeration devices is reduced.

Description

technical field [0001] The invention relates to the field of sewage biochemical treatment, in particular to an aerobic pool circulation aeration system. Background technique [0002] Aeration in sewage treatment is the process link with the highest operating cost in the sewage aerobic biochemical treatment system. Sufficient oxygen supply must be completed by aeration equipment. However, the power consumption of aeration equipment generally accounts for the total power of sewage treatment. Therefore, it is of great significance to choose aeration equipment with low energy consumption and low cost. [0003] In view of the low aeration efficiency of the aerator in the current conventional aerobic tank; the motor equipment used for supporting equipment has a large power and high pressure; the sludge in the tank is not uniformly dispersed, and there is sludge deposited in the corner, which leads to incomplete nitrification reaction. The aeration effect is improved by optimizing...
