Submersible plug-flow aeration device and sewage treatment method

Abstract

The invention discloses a submersible plug flow aeration device and a sewage treatment method, and belongs to the technical field of sewage treatment. The device comprises an aeration fan, a main aeration pipe and a rotary aeration pipe, the rotary aeration pipe is connected with the aeration fan through the main aeration pipe, and an aeration part with the aeration direction perpendicular to the axial direction of the rotary aeration pipe is arranged on the rotary aeration pipe; the rotary aeration pipe is horizontally arranged at the bottom of the sewage pool and is rotatably connected with the aeration main pipe, the rotation of the rotary aeration pipe can drive the aeration component to rotate in a vertical plane, and a rotation plane formed by the rotation of the aeration component is parallel to the flowing direction of sewage. Aeration and submersible plug flow equipment can be integrated, submersible plug flow, stirring and internal reflux equipment can be reduced or even canceled, and the problem that an aeration part in a single aeration direction is easy to block is avoided.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and more specifically relates to a submersible push flow aeration device and a sewage treatment method. Background technique [0002] Existing A N / O biological pool design, in order to deal with the problems of low influent water quality concentration and large water quality fluctuations in the initial stage of sewage plant commissioning, on the basis of configuring biological pool aeration equipment according to the designed water quality, a large number of push flow equipment was added, borrowed from push flow The flow equipment and aeration equipment are alternately started and stopped to adjust the volume ratio of anoxic and aerobic, so as to achieve the purpose of energy-saving operation and coping with water quality fluctuations. However, due to the relatively fixed positions of the auxiliary plug-flow equipment and aeration equipment, there is limited room for adjustment, and th...
