Anaerobic water jet stirring device for sewage treatment

Abstract

The invention relates to an anaerobic water jet stirring device for sewage treatment. The anaerobic water jet stirring device comprises a water pool, wherein a water pump, a main pipe and a plurality of manifold pipes communicated with the main pipe are arranged in the water pool, a water outlet of each manifold pipe is respectively provided with a nozzle, a water outlet of the water pump is communicated with a water inlet of the main pipe, a sensor is arranged on the main pipe, a controller is arranged outside the water pool, the controller is electrically connected with the sensor through a data wire, and the controller is electrically connected with the water pump through an electric wire. The anaerobic water jet stirring device disclosed by the invention has the advantages that original sewage in the water pool is used as a stirring medium, the sewage in the water pool is pumped into the main pipe by using the water pump, and the sewage enters all the manifold pipes and is jetted from the nozzles at a high speed, so that the sewage in the water pool can be effectively stirred. When the anaerobic water jet stirring device is used, because no rotary stirring component is needed, the faults and the maintenance amount can be reduced; and the anaerobic water jet stirring device is reliable in operation and free of dead angle during stirring due to reasonable arrangement of the plurality of manifold pipes and the nozzles in the water pool.

Description

technical field [0001] The invention provides a sewage treatment stirring device, specifically a sewage stirring device applied in the anaerobic section of sewage treatment. technical background [0002] The existing sewage mixing device in the anaerobic section of sewage treatment uses a submersible mixer. The submersible mixer puts the stirring fan blade with the motor under the water and stirs the sewage by the rotation of the fan blade. However, the impurities in the sewage Many, this kind of submersible mixer has rotating parts, and flexible impurities are often wound on the fan blade or shaft, so the failure rate is high in sewage and the operation reliability is low. There are dead angles when stirring the sewage in the pool. Another sewage stirring method is trace gas stirring, but this method is not suitable for the anaerobic section of sewage treatment because air is used as the stirring medium.
