Description
Technical field
The invention belongs to a kind of wastewater processing technology, a kind of new technique with regard to sedimentation tank, specifically a kind of rectangle is from week
Side intakes and the second pond from peripheral effluent.The new second pond structure is novel, and operational effect is good, efficiency high.
Background technology
Sedimentation tank is widely used in sewage treatment process, it using the sludge or various float in mixing liquid from
Heavy sensation of the body amount, is precipitated under gravity, is then concentrated the sludge and various float removed in water, is reached solid-liquid separation dirty
The purpose of Water warfare.The effect of second pond mainly carries out the precipitation of sludge, and its precipitation is non-in sewage treatment process
It is often important.Traditional second pond, side water inlet, side water outlet.The shortcoming of this structure is：Wastewater influent is disturbed to the water body in pond
It is dynamic larger, it is unfavorable for the rapid precipitation of sludge；Wastewater influent concentrates side, it is impossible to is uniformly distributed in pond as early as possible, makes full use of
The volume of cell body, accelerates sludge settling；Spoil disposal row froth structure is also not efficient enough, thus operational effect and efficiency are not ideal enough.
Hence it is highly desirable to propose that a kind of structure is more reasonable, rapid water distribution of intaking is uniform, and sludge settling is fast, and spoil disposal deslagging is quick, fortune
Row effect and the more preferable second pond of efficiency, to obtain more preferable productivity effect.
The content of the invention
The invention aims to solve above-mentioned technical problem, propose that a kind of rectangle Zhou Jinzhou goes out second pond.This two sink
Pond, using the structure of circumferential water feed peripheral effluent, in making pond, sewage is quickly and evenly distributed, and forms the water beneficial to rapid precipitation
Stream flow direction；The collection discharge structure of more rational sludge scum silica frost and sludge is set, reached that Inlet and outlet water is quick, water distribution is uniform,
Sludge settling is fast, and mud extraction is slagged tap easily effect, is a kind of new second pond of ideal sewage disposal.
