Specific embodiment

Illustrate the content of the utility model below in conjunction with specific embodiments.

In conjunction with Fig. 1, the utility model proposes a kind of rainwater purification recovery system, including collecting pit 1, filtering ponds 2, flocculation Pond 3 and tank 4.

Rain inlet pipe is connected at the top of the collecting pit 1,1 bottom of collecting pit has dirt discharge groove, in the dirt discharge groove Equipped with dredge pump 11, the bottom of the collecting pit 1, which is equipped with, leads dirty plate 16, and described to lead dirty plate 16 with the gradient, lower end is close The dirt discharge groove.

The water inlet of the filtering ponds 2 is connected to by the first water inlet pipe 81 with the water outlet of the collecting pit, and described first The first elevator pump 5 is connected on water inlet pipe 81；Be equipped in the filtering ponds 2 is in height bit distribution three layer filtration net 25, three layers of mistake It is respectively formed with metalling 22, sand stone layer 23 and active carbon layer 24 on strainer 25, is linked on the filter screen 25 of bottom Biochemical filler 26.

The water inlet of the flocculation basin 3 is connected to by the second water inlet pipe 82 with the water outlet of the filtering ponds 2, and described second It is connected with the second elevator pump 6 on water inlet pipe 82, is equipped in the flocculation basin 3 by the rabbling mechanism 31 of the driving rotation of motor 32, institute It states and is additionally provided with the dosing box 33 for being loaded with flocculant on flocculation basin 3.

The water inlet of the tank 4 is connected to by third water inlet pipe 83 with the water outlet of the flocculation basin 3, the water storage The bottom in pond 4 is equipped with sewage draining exit 43, is equipped with filter bowl 41 in the tank 4,41 lower end closed of filter bowl, on the filter bowl 41 It is equipped with the second outlet pipe, the import of second outlet pipe is located in the filter bowl 41, the outlet position of second outlet pipe In the outside of the tank；The outlet of the third water inlet pipe 83 is located at the outside of the filter bowl 41.

In above scheme, rainwater enters collecting pit 1 by rainwater inlet pipe, and accumulates in 1 bottom of collecting pit.1 bottom of collecting pit Portion leads dirty plate 16 and can import the impurity such as sludge in dirt discharge groove, and the impurity such as sludge is discharged in time by dredge pump 11, has The turbidity for helping reduce rainwater in collecting pit 1, mitigates subsequent filter processing load.

The rainwater in collecting pit 1 can be introduced filtering ponds 2 by the first elevator pump 5.In filtering ponds 2, rainwater successively by The filtration of metalling 22, sand stone layer 23 and active carbon layer 24 makes the solid impurity being mixed in rainwater be separated.Filtering Rainwater afterwards falls into the bottom of filtering ponds 2, and by the effect for the microorganism for being attached to biochemical filler 26, has got rid of in rainwater Organic matter.

Flocculation basin 3 is introduced by the second elevator pump 6 with the rainwater after biochemical treatment by filtering, can be inhaled by adding flocculant Remaining impurity in attached water.Rainwater after flocculation treatment introduces tank 4 by third elevator pump 7, due to being provided with filter bowl 41, And second outlet pipe water inlet be arranged in filter bowl 41, because flocculation treatment generate impurity be isolated in outside filter bowl 41.It is needing When with water, the valve on the second outlet pipe can be directly opened, is flowed out by repeatedly treated rainwater by the second outlet pipe 93, It is discharged the use that can be used for irrigating or washing one's face and rinsing one's mouth.

It is connected with L shaped plate 13 in the collecting pit 1, permeable hole, the L shape plate are penetratingly offered in the L shaped plate 13 Collecting tank 15 is cooperatively formed between 13 and 1 side wall of the collecting pit, is equipped in the collecting tank 15 and is blocked dirty basket 14；The collecting pit Garbage barrier net 12 is also connected in 1, the garbage barrier net 12 is obliquely installed, and lower end is overlapped on the L shape plate 13, higher End is overlapped on the side wall of collecting pit 1.

Primary filtration can be carried out to rainwater by garbage barrier net, rainwater can fall in collecting tank 15 through the mesh on garbage barrier net 12 Interior, impurity is then isolated in garbage barrier net.Since garbage barrier net is obliquely installed, impurity can be moved along garbage barrier net, and eventually fallen into and blocked In dirty basket 14, the certifiable available capacity for blocking dirty basket 14 of dirty basket 14 is blocked by timing cleaning.

Due to blocking in dirty basket 14 there is also a certain amount of water, the water in dirty basket 14 is blocked in the mesh by blocking dirty basket 14 Afterwards, it falls in L shaped plate 13, and is fallen into collecting pit 1 by permeable hole.

Sparge pipe 21 is connected in the filtering ponds 2, the sparge pipe 21 is closed at one end, the other end and first water inlet The water outlet of pipe 81 is connected to, and the sparge pipe 21 is located at the top of the metalling 22, and the sparge pipe 21 is horizontally disposed, edge Axially it is communicated with multiple spray heads.Rainwater can be made uniformly to fall into filtering ponds 2 by this design, can effectively to rainwater filtering effect Rate.

The collecting pit 1 is communicated with the first outlet pipe 91, can be arranged the rainwater in collecting pit 1 by the first outlet pipe 91 Out, water outlet can be used for irrigating.

The tank 4 has overflow port 42, is communicated with return pipe 92, second outlet pipe at the overflow port 42 93 outlet is located at the top of the metalling 22.When amount of rainfall in tank 4 reaches design capacity, rainwater can be by overflowing Head piece 42 and return pipe 92 flow back into filtering ponds 2.Since there are a certain amount of impurity in the rainwater in tank 4, in rainwater After flowing back into filtering ponds 2, the rainwater of reflux can also be refiltered by multiple filter layers.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
