The Sludge a layer Sedimentation prevent Equipment in Oxidation Ditch use of water power and air bubble.

摘要

The present invention is a technique related to the oxidizing sphere used as a microbial reaction tank in sewage treatment or wastewater treatment. ; It is an object of the present invention to provide an apparatus capable of preventing the sludge deposition occurring near the start of the straight line of the inner wall of the curved portion of the oxidation sphere. ; In order to achieve the above object, in order to achieve the above object, in order to prevent the sludge layer (D) accumulated on the floor near the start of the straight portion (B) of the oxidizing sphere bow (B) of the curved portion for a certain period of time, the inner wall surface of the straight portion (B) By operating the air / water supply valve (4) from the air / water supply valve (4) according to the situation by the nozzle through the air / water supply pipe (2) where the sludge layer (D) is stacked by using a flotation force to prevent sludge deposition I made it. ; The device for preventing sludge deposition in the oxidative sphere using air / water of the present invention has the effect of preventing the deposition of sludge in a specific part of the oxidizing sphere by air discharge or water action, thereby improving water treatment efficiency.
