Description

Pump drainage type decanter

Technical Field

The utility model relates to a water decanter technical field that is relevant, concretely relates to pump drainage formula water decanter.

Background

SBR is a short name of a sequencing batch activated sludge process, and is an activated sludge sewage treatment technology which operates in an intermittent aeration mode. The main characteristic is orderly and intermittent operation in operation, the core of SBR technique is SBR reaction tank which integrates the functions of homogenization, primary sedimentation, biodegradation, secondary sedimentation and the like in a first tank without sludge reflux system. The device is particularly suitable for occasions with insufficient construction space, intermittent discharge and large flow change. Has wide application in China. The decanter is a key device of a sequencing batch activated sludge process.

The decanter is a device for periodically removing clear water adopted by SBR technology, and has the function of decanting the clear water from the surface of a static tank without stirring and precipitating to ensure the quality of the discharged water. The water decanter can be divided into a siphon water decanter, a rotary water decanter, a self-floating water decanter and a mechanical water decanter, and is widely applied to China and is mainly a rotary type (belonging to one of the mechanical water decanters).

The rotary decanter pushes the vertical decanting pipe by a mechanical push rod to drive the decanting weir notch to descend so as to discharge the pool water out of the pool. The decanter is most commonly applied in China, and has the advantages that weir flow is adopted for water discharge, and the water discharge is uniform. The siphon decanter is fixed in the tank and does not change along with the change of the water level, and the periodical drainage can be realized by controlling the opening and closing of the siphon valve. The flexible tube type floating decanter is used for decanting water, the decanting hole tube is generally hung about 600mm below the floating barrel, when the water is decanted, a floating decanting head on the hole tube and a gate of a bottom drain pipe are opened by an electric and pneumatic device to drain water, and the device can automatically realize uniform decanting because the decanting hole tube is always kept at a depth of about 600mm below the water surface, does not need manual adjustment and is convenient to operate.

The rotary decanter mainly has two problems, one is that the decanter can only be mounted by the tank wall, the outlet weir is short and is generally about 10m, and the weir groove only has one side for decanting, the water yield of the unit weir width is large, and the sludge is easy to be carried, and the other problem is that the decanter rotates and descends, and the vertical descending speed of the weir crest is greatly increased due to the fact that the vertical pipe of the decanted water is close to the horizontal state when the water is decanted to the tail end, and the descending speed of the weir crest needs to be slowed down by adopting a frequency conversion control technology, so that a more complex automatic control technology is required, and the prior art needs to be improved. The siphon decanter drains water through the inlet of the pipe orifice below the vertical pipe, which has two adverse factors for decanting water, on one hand, when the decanter starts, the bottom opening of the vertical pipe is at a deeper position and is closer to a mud surface, so that mud is easily carried, and on the other hand, the area of the bottom opening of the vertical pipe is small, so that the flow velocity entering the pipe orifice is larger, and the mud carrying phenomenon is easily generated. The flexible tube floating decanter has the defect that the phenomenon of mud entering and carrying is easy to occur due to the small area of the water inlet hole of the hole tube.
