Technical problem to be solved in the utility model is: the sewage transport system providing a kind of biochemical sewage treating pond, the gas volume brought into when this sewage transport system can reduce the draining of biochemical sewage treating pond, reduce the air supporting phenomenon of settling tank, improve the sedimentation effect of settling tank.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of sewage transport system of biochemical sewage treating pond, comprise sewage running piping, one end of this sewage running piping connects the water port of biochemical sewage treating pond, the other end connects the water-in of settling tank, the water port height of biochemical sewage treating pond is higher than the water-in height of settling tank, described sewage running piping comprises Upstream section and tract, Upstream section is communicated with by surge tank with tract, this surge tank is provided with the flowrate control valve controlling tract flow.
As the preferred scheme of one, described flowrate control valve comprises the valve seat be fixed on surge tank, and this valve seat is vertically slidably fitted with valve plate, and the plate face of this valve plate coordinates with the entrance of tract, is provided with valve plate driving device between this valve plate and valve seat.
As the preferred scheme of one, described valve plate driving device comprises the screw rod vertically rotating and be installed on valve seat, rotate loose joint between the lower end of this screw rod and valve plate, described valve seat is provided with the nut coordinated with screw flight, the upper end of screw rod is fixedly installed handwheel.
As the preferred scheme of one, the entrance of described tract is provided with elbow, and this elbow and surge tank are fixed, and described valve plate coordinates the open area controlling elbow inlet with elbow.
As the preferred scheme of one, described valve seat comprises the vertical guide rail of two of the sidewall being fixed on surge tank, and the upper end of two vertical guide rails is fixed with top end rail, and described nut is fixed on top end rail.
As the preferred scheme of one, described handwheel is near one of them sidewall of surge tank.
As the preferred scheme of one, described valve seat comprises the rectangular frame be fixed on elbow, and the both sides of this rectangular frame are provided with vertical guide rail, and described nut is installed on rectangular frame, and described valve plate is vertically slidably mounted on the vertical guide rail of rectangular frame.
After have employed technique scheme, effect of the present utility model is: the one end due to this sewage running piping connects the water port of biochemical sewage treating pond, the other end connects the water-in of settling tank, the water port height of biochemical sewage treating pond is higher than the water-in height of settling tank, described sewage running piping comprises Upstream section and tract, Upstream section is communicated with by surge tank with tract, this surge tank is provided with the flowrate control valve controlling tract flow.This sewage running piping adopts segmental structure and utilizes surge tank as buffering, even if so the water displacement of biochemical sewage treating pond is anxious greatly, after so entering into surge tank, buffering slows down flow velocity, a large amount of sewage of buffer memory in surge tank, then flowrate control valve is utilized to control the flow entering tract, the sewage that tract entrance enters is positioned at the sewage below surge tank liquid level, like this, the inlet of gas greatly reduces, reduce the air supporting phenomenon of settling tank, improve the sedimentation effect of settling tank.
Again because the entrance of described tract is provided with elbow, described valve plate coordinates the open area controlling elbow inlet with elbow, utilizes elbow can play certain drainage to current, avoids sewage vertically enter and introduce gas.
