High-efficiency aeration tank for municipal wastewater treatment

Abstract

The invention discloses a high-efficiency aeration tank for municipal wastewater treatment. The high-efficiency aeration tank comprises an aeration cavity, a transmission cavity and a blower, whereina motor is arranged inside the transmission cavity; a rotating shaft is fixedly connected with the output end of the motor; a threaded sleeve is uniformly sleeved to a screw rod; a first rotating rodis arranged on the outer side of the screw rod; lantern rings are articulated with the left and right ends of the first rotating rod; a stirring rod is glidingly connected with the interior of the sleeve; rack boards are symmetrically arranged at the left and right ends of the aeration cavity; a rectangular plate is arranged on the outer side of each rack board; second rotating rods are rotationally connected with the inner side of the rectangular plate in a longitudinally symmetrical way; the other end of each second rotating rod is communicated with a coil pipe. The high-efficiency aerationtank is novel in design, improves the stirring effect of wastewater, ensures that gas is more sufficient to be in contact with the wastewater, is good in aeration effect, ensures that air exhausted through an aeration head is more sufficient to be in contact with the wastewater as the coil pipes are driven through the second rotating rods to rotate while moving longitudinally, and improves the aeration efficiency.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a high-efficiency aeration tank for municipal sewage treatment. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. It is generally used for the preliminary treatment of sewage. The mixing condition of activated sludge fully contacting. The aeration tank is mainly composed of three parts: the tank body, the aeration system and the water inlet and outlet. The aeration methods are mainly divided into blast aeration and mechanical aeration. The existing aeration tanks often have a relatively single aeration mechanism, long aeration time, and low aeration efficiency, which are difficult to meet people's growing sewage treatment needs. . Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency aeration tank for municipal sewage treatment to solve the problems raised...
