Background

The effect of secondary sedimentation tank is mud-water separation, make mixed liquid clear away, mud concentration and the mud with the separation return the biological treatment section, the quality of its effect, the quality of water and the concentration of backward flow mud of direct influence play water, because precipitation and concentration effect are not good, will increase the activated sludge suspended solid in the play water, thereby increase the BOD mass concentration of play water, simultaneously, backward flow mud concentration also can reduce, thereby reduce mixed liquid concentration in the aeration tank, influence purifying effect secondary sedimentation tank activated sludge's another characteristics and be matter light, easily be taken away by play water, and produce the secondary flow phenomenon easily, make the water section of crossing of reality be less than the water section of design far away. Therefore, when the secondary sedimentation tank is designed, the maximum allowable horizontal flow rate is smaller than the effluent overflow of a half of the primary sedimentation tank by a certain distance and is buried in the range of the other end of the tank; the radial flow secondary sedimentation tank can also improve the flowing distance and sedimentation effect of the mixed liquid in the tank by using a peripheral water inlet and peripheral water outlet mode. The secondary sedimentation tank goes out water and is the play water mode that adopts the triangle weir mostly, and clear water turns over after the triangle weir evenly and gets into in the water collecting channel and outside the discharge pond, requires during the design that the whole pond weir crest elevation error is no longer than 2mm, but during actual construction, often hardly satisfies this requirement and the weir plate height also is difficult for adjusting in the operation, causes whole pond weir load inequality.

However, for the radial sedimentation tank with a larger tank diameter, when wind exists, the load of the weir on the windward side is obviously higher than that of the leeward side, so that more suspended solids enter the water from the high weir load side, and the effect of mud-water separation of the secondary sedimentation tank is influenced. Therefore, the technical personnel in the field provide a uniform water outlet device of a secondary sedimentation tank to solve the problems in the background technology.
