Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2, a kind of embankment formula of the present invention early-stage rainwater interception-storage-processed group assembly system, comprise the catchpit 1 be communicated with municipal rain pipe 7 be arranged on river levee, weir 2 of damming is provided with in catchpit 1, catchpit 1 is communicated with storage/sediment tube 3, and storage/sediment tube 3 is arranged along river levee length direction under river levee, and storage/sediment tube 3 is communicated with catch-basin 4 and manhole 5, wherein catch-basin 4 is between catchpit 1 and manhole 5, and catch-basin 4 is connected with system outlet pipe 6.System outlet pipe 6 can be communicated to river course, also can be communicated to other advanced treatment apparatus.In figure, A is river course, and B is river levee, and C is road along the river.
As shown in Fig. 3, Fig. 4 and Fig. 5, municipal administration rain pipe 7 is connected to the middle and upper part of catchpit 1, the bottom of catchpit 1 is connected to river course by rainwater outlet pipe 8, and storage/sediment tube 3 is arranged on the medium position of catchpit 1, spatially all vertical with rainwater outlet pipe 8 with municipal rain pipe 7.Weir 2 of damming retains weir plate for rectangle, with grid 9, be arranged on the nozzle position of rainwater outlet pipe 8, between the overhead height that its overhead height is in storage/sediment tube 3 and bottom level, its height demand fulfillment i.e.: during (1) rainfall, ensure certain rain water storage storage, when the water level in catch-basin lower than dam weir 2 time, can will carry in region area source pollutants early-stage rainwater interception in storage/sediment tube 3; (2) ensure that the non-flowing full of storage/sediment tube 3 stores rainwater, dam weir 2 highly a little less than or equal the design height of storage/sediment tube 3.
Precipitation/storage tube 3 is for temporarily storing rainwater, and have precipitation to the area source pollutants that rainwater carries, its design caliber need meet: (1) Guan Weifei flowing full designs, the degree of filling of about 70% ~ 90%, actual storage rainfall should guarantee temporary storage area early-stage rainwater amount of calculation; (2) caliber is unsuitable excessive, and absolute altitude at the bottom of pipe is higher than the river water surface, and control river pours in down a chimney; (3) conduit slope is 0.1% ~ 0.5%, and wherein the second half section is the reverse gradient of first half section.Namely, two sections can be divided into, it is first paragraph between catchpit 1 and catch-basin 4, it is second segment between catch-basin 4 and manhole 5, in first paragraph, direction along from catchpit 1 to catch-basin 4, has the gradient of downward 0.1% ~ 0.5%, passes through deadweight flow to catch-basin 4 from catchpit 1 to make deposit; In second segment, the direction along manhole 5 to catch-basin 4, has the gradient of downward 0.1% ~ 0.5%, passes through deadweight flow to catch-basin 4 from manhole 5 to make deposit.
As shown in 2 and Fig. 6, catch-basin 4 is positioned at the centre position of storage/sediment tube 3, and the height of storage/sediment tube 3 is higher than the shaft bottom height of catch-basin 4, and rainwater is by realizing sandstone precipitation after catch-basin 4, system outlet pipe 6 is connected to the position, middle and upper part of catch-basin 4.The bottom of catch-basin 4 than catchpit 1 and the dark 0.5 ~ 0.7m of manhole 5, be conducive to deposit in both sides storage/sediment tube 3 along the unpowered remittance of the gradient to catch-basin 4 in store.
System outlet pipe 6 communicates with catch-basin 4, and storage/sediment tube 3 has the ponding ability of 10% ~ 20%, for ensureing that storage/sediment tube 3 can not be stored by blank pipe, the position of system outlet pipe 6 a little more than or equal with 10% ~ 20% of storage/sediment tube 3.System outlet pipe 6 water outlet directly can enter river, or accesses other percolating devices and enter in river course after reaching better Effects of Water Quality again.
The present invention can arrange the dam main parallel with water body along bank of river, the appropriate location of main of damming arranges catchpit 1, makes to exceed the dam part combined sewage of dry tube designs conveyance power of water and can be smoothly through catchpit 1 and enter water body (i.e. river course) nearby.
Rainwater interception of the present invention, area source pollutants handling process and operating principle are as follows:
1) just rain interception step: in predetermined first rain period, the rainwater that municipal administration rain pipe 7 is collected enters catchpit 1, the rainwater not exceeding weir 2 height that dams is dammed and is got off to enter storage/sediment tube 3, overage directly enters river course by rainwater outlet pipe 8, dam to realize alternative, efficiency is higher;
2) first rain treatment and discharge step: the area source pollutants that rainfall runoff carries sedimentation in storage/sediment tube 3, the rainwater after process enters river course or other advanced treatment apparatus at catch-basin 4 by system outlet pipe 6.
3) sedimental disposal: after first rain diafiltration to river course, deposit is by bottom storage/sediment tube 3, bottom catch-basin 4 and the bottom deposit of manhole 5.Adopt perforated pipe douching technique, sectional flushing storage/sediment tube 3, deposit is rinsed the downstream manhole 5 to every section.Finally unification siphons away disposal by silt pumping car.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For those skilled in the art, without departing from the inventive concept of the premise, some equivalent to substitute or obvious modification can also be made, and performance or purposes identical, all should be considered as belonging to protection scope of the present invention.
