Abstract

The utility model provides a sewage and sludge treatment pond, which is used for solving the problems of high mounting cost and inconvenience for maintenance of the treatment pond in the prior art. The sewage and sludge treatment pond comprises a sewage and sludge settling pond and a plurality of sewage settling ponds which are arranged sequentially, wherein a sewage inlet from which sewage to flow in is formed in the sewage and sludge settling pond; an overflow port is formed between the two adjacent settling ponds; and the bottoms of the sewage and sludge settling pond and the sewage settling ponds are shaped like an oblique cone. The regular conical pond bottoms of the settling ponds are changed into the oblique conical bottoms, so that the sediment of the sewage and the collection of sludge liquid are facilitated, and the mounting and the maintenance of sewage treatment related equipment in the treatment pond are facilitated; and a primary sewage settling pond and a sludge storage and settling pond are combined into the sewage and sludge settling pond, so that the occupying area and the engineering cost of the treatment pond are reduced and the good practicability is achieved.

Description

Sewage and sludge treatment pond

Technical field

The utility model relates to the water treating equipment technical field, relates in particular to a kind of novel sewage and sludge treatment pond

Background technology

At present, in middle-size and small-size sewage disposal and sludge treating system, the design for the treatment of pond mainly contains two kinds:

A kind of is flat treating pond, easy construction, and construction costs is lower, for the system of three grades of precipitation process of sewage, generally designs 4 treating ponds, is respectively sewage one-level settling tank, sewage second-level settling pond, three grades of settling tanks of sewage, mud settlement on storage pond; The sewage disposal flow process is generally: sewage at first enters the one-level settling tank, enter sewage second-level settling pond, three grades of settling tanks of sewage after overflowing successively, waste disposal plant extracts sewage from three grades of settling tanks, in forming after the comprehensive treating process water and enter in the water bin, the sludge liquid that produces in the sewage treatment process enters mud settlement on storage pond; The flow process of sludge treatment is: center large-scale whipping appts of installation stirs sludge liquid above mud settlement on storage pond, sludge treatment equipment extracts sludge liquid from mud settlement on storage pond, handle the isolated sewage in back through sludge treatment equipment and return sewage one-level settling tank, isolated mud is unified to handle as solid waste.

In use mainly there is following problem in the above flat treating pond: one, the whipping appts power of sludge sump is big, the installation cost height, and maintenance is inconvenient; Two, because the flowability of pool bottom sludge liquid is poor, the sludge liquid in having only around the pump very among a small circle can extract, and needs repeatedly the position of moving pump at the bottom of the pond, has both bothered also dangerous; Three, three settling tanks need regularly clear pond, and workload is very big, have between the cleaning Vehicle of 2 high capacity cars, just need employ crane, excavator, dump truck average per 2 weeks and carry out once clear pond operation, need consumption great amount of manpower and material resources and financial resources.

Another kind is the positive cone treating pond, compare with flat treating pond, the flow process of sewage disposal and sludge treatment is identical, because the pond bottom structure changes down positive taper into, be conducive to the precipitation of sewage and the collection of mud, pump is placed on center at the bottom of the pond, can exhaust the sludge liquid at the bottom of the pond basically, and the position of mobile pump repeatedly, but the other problem that flat treating pond exists still is not resolved.

The utility model content

The utility model proposes a kind of sewage and sludge treatment pond, solved treating pond installation cost height in the prior art, the inconvenient problem of maintenance.

The technical solution of the utility model is achieved in that sewage and sludge treatment pond, comprise the sewage sludge settling tank and a plurality of detention tank that are arranged in order, have on the described sewage sludge settling tank for the sewage inlet that flows into sewage, be equipped with overflow port between two adjacent settling tanks; Be at the bottom of the inclined to one side conical tank at the bottom of the pond of described sewage sludge settling tank, described detention tank.

As preferred embodiment a kind of, comprise an awl end horizontal plane and four sides at the bottom of the described inclined to one side conical tank, one of them side is the treating pond vertical side perpendicular with horizontal plane at the bottom of the described awl, and other three sides are and the inclined to one side awl inclined-plane in obtuse angle of horizontal plane at the bottom of the described awl.

As to improvement of the technical scheme, in the described sewage sludge settling tank, be equipped with sludge pump in the described detention tank.

As preferred embodiment a kind of, the number of described detention tank is two.

After having adopted technique scheme, the beneficial effects of the utility model are: change at the bottom of the inclined to one side awl pond at the bottom of the positive cone pond with settling tank of this sewage and sludge treatment pond, be conducive to the collection of precipitation and the sludge liquid of sewage, be conducive to the I﹠M of sewage disposal relevant device in the treating pond; In addition, sewage one-level settling tank and mud settlement on storage pond are merged into the sewage sludge settling tank, reduced floor space and the engineering cost for the treatment of pond.

This sewage and sludge treatment pond in sewage sludge settling tank, detention tank all design and installation sludge pump, solved the online timely cleaning problem of settling tank bottom sludge liquid.
