Abstract

The invention relates to an urban rain water purification pipe network, which comprises a rain water pipe, an intake pipe of a sewage plant and a river entrance pipe, wherein the intake pipe and the river entrance pipe are connected with the rain water pipe respectively. A detachable mud storage tank is arranged at the lower part of the inside of the rive entrance pipe. A sudden expansion ceramic pipe of which the upper part of the inside is in a concave-convex indented shape is arranged in the river entrance pipe behind the detachable mud storage tank. A ceramsite filter tank is arranged at a river entrance in the river entrance pipe. Rain water not processed by the sewage plant flows into the river entrance pipe, passes through the detachable mud storage tank for mud sedimentation and flows into the sudden expansion ceramic pipe to be stirred and filtered for further reducing the content of harmful substances and water purification, and then passes through the ceramsite filter tank arranged at the river entrance of the river entrance pipe or an arranged platform having nitrogen and phosphor absorbing plants for filtration and absorption before being discharged into a river, so the discharge of the rain water meets quality standards for discharge and avoids river pollution.

Description

Urban rainwater purification pipe network

Technical field

The present invention relates to a kind of sewage network, especially a kind of pipe network that can purify urban rainwater.

Background technology

Traditional Storm Sewer Network is directly rainwater to be entered the korneforos.But the rainwater that washes away ground during rainfall can be always unclean, and is especially true behind prolonged drought.The rainwater that washes away ground at first can run into a lot of pollutents, as lead, dust, polycyclic aromatic hydrocarbons, and the salt of separating out winter, rubber etc.The more important thing is that storm sewer also can more residual rainwater, before raining, pump back severe contamination water body.

Summary of the invention

The purpose of this invention is to provide a kind of pipe network that can purify urban rainwater.

The present invention includes storm sewer with the Sewage Plant inlet channel that is connected respectively with it, go into the river pipeline, the bottom is provided with detachable storage mud groove in going into the river pipeline, go into the sudden expansion ceramic tube that is provided with the concavo-convex indentation of its inside upper part in the pipeline of river after detachable storage mud groove, the debouchment place of going in going into the river pipeline is provided with the haydite filtering basin.

And the entrance end at detachable storage mud groove, sudden expansion ceramic tube and haydite filtering basin is provided with filtering net.

At the Sewage Plant inlet channel, go into a conversion gate is arranged between the pipeline of river, be provided with under meter, water quality testing meter in the described storm sewer, this under meter and water quality monitoring system link to each other with the conversion gate by electric control unit.

Go into the platform that the debouchment place is provided with adsorption of nitrogen phosphorus plant outside going into the river pipeline, the platform rear side is equipped with by supported arm and controls liftable collapsible impeller.

The under meter, the water quality testing meter that are provided with in the pipeline can be according to the unlatchings of the water yield and the in good time control gate of water quality, regulate rainwater and enter sewage work, carry out purifying treatment, the water quality of rainwater is discharged in allowed limits, unlikely river water is polluted.

The rainwater of handling without sewage work enters into the river pipeline, flows into sudden expansion ceramic tube after the sludge settling process through detachable storage mud groove, and rainwater carries out the disturbance filtration therein, further reduces the content of nuisance, purifies water; Enter the river after the platform that adsorption of nitrogen phosphorus plant is arranged of haydite filtering basin of going into the setting of place, river mouth through going into the river pipeline or setting filters, adsorbs again, guaranteed the discharging of rainwater water quality reaching standard, avoid pollution the river.

The platform rear side is equipped with collapsible impeller, and supported arm 15 can drop to impeller with river plane contact place and start, and can play the aeration effect, simultaneously river is kicked up, and gets on the bank, with the secondary action of adsorption of nitrogen phosphorus plant, plays the effect of further purifying water body.

Fig. 2 is the haydite filtering basin synoptic diagram that the place, river mouth is provided with of going into into the river pipeline;

Fig. 3 is into the platform of the attached nitrogen phosphorus plant that goes into the setting of place, river mouth of river pipeline and the synoptic diagram of the liftable collapsible impeller of platform rear side.

Embodiment

Below in conjunction with description of drawings the present invention.

The present invention includes storm sewer 1 with the Sewage Plant inlet channel 5 that is connected respectively with it, go into river pipeline 6, at the Sewage Plant inlet channel, go into a conversion gate 4 is arranged between the pipeline of river, be provided with under meter 2, water quality testing meter 3 in the storm sewer, this under meter links to each other with the conversion gate by electric control unit 10 with water quality monitoring system.The interior bottom of river pipeline of going into of urban rainwater purification pipe network is provided with detachable storage mud groove 8, is provided with sudden expansion ceramic tube 9 in the pipeline after storage mud groove.Sudden expansion ceramic tube is the pipeline of the concavo-convex indentation in top.Be provided with haydite filtering basin 11 at the place, river mouth of going into of going into the river pipeline.The sewage in-out end of described detachable storage mud groove, sudden expansion ceramic tube and haydite filtering basin is provided with filtering net 7.Go into the platform 12 that the debouchment place is provided with adsorption of nitrogen phosphorus plant 13 outside going into the river pipeline, the platform rear side is equipped with by supported arm and controls liftable collapsible impeller 14.

Under meter in the pipeline, water quality testing meter are according to the unlatching of the water yield and the in good time control gate of water quality, when rainwater water quality is relatively poor, opens control gate and make rainwater enter sewage work, carry out purifying treatment, the water quality of rainwater is discharged in allowed limits, unlikely river water is polluted.

When the rainwater water yield is big, harmful substance contents in the rainwater is relatively low, at this moment, to open rainwater and go into the river pipeline, close the Sewage Plant inlet channel, the rainwater of handling without sewage work is entered into the river pipeline, flow into sudden expansion ceramic tube after the sludge settling process through detachable storage mud groove, rainwater carries out the disturbance filtration therein, further reduces the content of nuisance, purifies water; Enter the river after the platform that adsorption of nitrogen phosphorus plant is arranged of haydite filtering basin of going into the setting of place, river mouth through going into the river pipeline or setting filters, adsorbs again, guaranteed the discharging of rainwater water quality reaching standard, avoid pollution the river.
