Description
Technical field
The present invention relates to urban combined sewerage process fields, and in particular to a kind of combined sewage shuts off purification device.
Background technique
Rain, dirty combined system construction are substantially pressed in the old town of China's early stage construction, according in " urban drainage statistical yearbook "
Investigation result show that currently, China has 20% city still to retain combined drainage system.In recent years, environmental problem highlights,
The problem of more and more places are faced with drainage system pipe network improving.For old town, construction and transformation difficulty are larger, close
Stream pipe network improving, major alterations are interceptive combined system drainage pipeline networks.
But rainy day interflow tubing giving sufficient strength combined sewage water is larger, and direct overflow, which enters river, will lead to the water ring of receiving water body
Border is contaminated, therefore results in the inland river water degradation in many cities, but to reduce environmental pollution, promoting interception ratio can be led
The water for causing rainy season to enter sewage plant is huge, and influent concentration is low, causes very big puzzlement to sewage plant operation.
Summary of the invention
The present invention provides a kind of combined sewage and shuts off purification device, to solve Vatch basin combined sewage of the existing technology
Part overflow outlet cause water pollution the problem of.
Shut off purification device, including water inlet pipe, filtering in order to solve the above technical problems, the present invention provides a kind of combined sewage
Layer, rainwater-collecting cylinder, backwash pump, Backwash pipeline, overflow weir and Vatch basin, the water inlet pipe is connected to Vatch basin, described
It is provided with filter layer in Vatch basin, is provided with overflow weir below the filter layer in Vatch basin, filter layer divides Vatch basin
At first area and second area, first area connects the first outlet pipe, for the sewage to shut off to be discharged into sewage network, second
Region connects the second outlet pipe, and for the clean water for passing through filter layer filtering to be discharged into river, the Vatch basin is nearby provided with
Rainwater-collecting cylinder is equipped with backwash pump in rainwater-collecting cylinder, and backwash pump is connect with Backwash pipeline, the backwash
Pipeline is the aqueduct for hanging over filtering layer surface, the apopore of face filter layer is provided on aqueduct, for filter layer
Automatic backwash.
The rainwater-collecting cylinder is embedded in underground, and filter layer is provided with around the cylinder of rainwater-collecting cylinder, and cylinder top is set
It is equipped with and receives water hole, cylinder upper layer receives water hole position and is higher than level of ground water, receives water hole aperture and is less than filter layer particle.
The rainwater-collecting cylinder is set on the ground, and rainwater-collecting cylinder top is equipped with disk shaped opening, and lower part is cylinder
The cylinder of shape, rainwater enter rainwater-collecting cylinder cylinder from opening.
The Vatch basin uses slot type Vatch basin, weir formula Vatch basin or slot weir convolution Vatch basin.
Bring of the present invention purification device the utility model has the advantages that (1) combined sewage of the invention shuts off, can be further processed conjunction
Sewage is flowed, environmental pollution caused by combined sewage is reduced.
(2) combined sewage of the invention shuts off purification device, it can be achieved that the automatic backwash based on rainfall, saves manpower
Cost makes filter layer be maintained at ideal operation state.
(3) combined sewage of the invention shuts off purification device, and outlet effect is preferable, easy to maintain, not only water outlet preferably, dimension
Shield is simple, and can suitably reduce interception ratio, to reduce sewage plant operating cost.

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with drawings and the specific embodiments, to this
Invention is described in further detail.
As shown in Figs. 1-2, the present invention provides a kind of combined sewage and shuts off purification device, including water inlet pipe 7, filter layer 1, rain
Water surge drum 2, backwash pump 3, Backwash pipeline 4, overflow weir 5 and Vatch basin 6, the water inlet pipe 7 are connected to Vatch basin 6, institute
It states and is provided with filter layer 1 in Vatch basin 6, be provided with overflow weir 5 below the filter layer 1 in Vatch basin 6, filter layer 1 will be cut
Stream well 6 is divided into first area 8 and second area 9, and first area 8 connects the first outlet pipe 10, for arranging the sewage to shut off
Entering sewage network, second area 9 connects the second outlet pipe 11, for the clean water for passing through filter layer filtering to be discharged into river, institute
It states Vatch basin 6 and is nearby provided with rainwater-collecting cylinder 2, backwash pump 3 is installed in rainwater-collecting cylinder 2, backwash pump 3 and anti-
