Aeration-type treatment equipment utilizing centrifugal force to swing and expand and contract for domestic wastewater

Abstract

The invention discloses aeration-type treatment equipment utilizing centrifugal force to swing and expand and contract for domestic wastewater. A structure of the equipment comprises a sewage funnel,a filter box, a sludge storage tank and an aeration device. According to the equipment provided by the invention, aeration check devices together with stirring blades rotate quickly by using a stirring rod as a center to stir the sewage and activated sludge, at the time, the tops of air ejecting pipes are connected with an air storage space, an airflow enters the interiors of the aeration check devices through the air ejecting pipes, after the air ejecting pipes are ventilated, the aeration check devices directly perform aeration treatment from the center to the periphery, so that the aerationeffect is greatly improved, the sludge and the sewage can be fully neutralized, and the sewage blowing effect can be improved; when a movable ball is thrown out by the centrifugal force, the movableball is located in the position of a through opening of a straight-through pipe, so that the splashed sludge can be prevented from entering directly; and if the sludge is splashed into an opening expending ring under stirring and drops to the movable ball, guide blocks are tilted along with the centrifugal force to slide the sludge out, so that sludge residues in movable ball can be avoided, and the aeration device is prevented from being clogged.

Description

technical field [0001] The invention relates to an aeration type domestic wastewater treatment device which utilizes centrifugal force to swing and expand, and belongs to the field of sewage treatment devices. Background technique [0002] With the improvement of the quality of life, the sewage in life continues to increase. Due to the presence of various food residues and chemicals in the sewage, if it is directly discharged, it will cause oxidative enrichment of the water body. The bacteria in the sewage are likely to cause a vicious cycle, pollute the water quality, and cause ecological pollution Destruction, usually requires the use of sewage treatment equipment to treat sewage, which needs to be fully contacted and mixed with activated sludge. Among them, the effect of aerated sewage treatment is more significant. [0003] However, the existing sewage treatment has the following disadvantages: [0004] 1. When using aeration-type sewage treatment, it is mostly used to ...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an aeration-type domestic wastewater treatment device that uses centrifugal force to swing and expand, so as to solve the problem that when aeration-type sewage treatment is used, most of them are used on the outer wall of the stirring box, that is, the aeration box or Vents are installed on the top, and the fan is used to send air into the aeration box. This aeration method can only supply oxygen to the sludge and sewage exposed on the upper side, and the effect is poor, because the sludge and sewage are easily splashed during stirring. Therefore, after long-term stirring, it is easy to make the sludge splash to the nozzle of the exhaust pipe. When the fan is stopped, because the airflow inside the exhaust pipe still has a low-speed flow in a short period of time and the atmospheric pressure is low, the sludge from the nozzle will be Suck back into the pipeline, prone to clogging
