1 grid pond, 2 sections of dirty grooves, 3 artificial grids, 4 drainage tanks, 5 bleed off pipes, 6PP module combination collecting pit, 7 composite geo-membranes, 8 blowdown manholes, 9 dredge pumps, 10 blow-off lines, 11 reuse manholes, 12 reuse pumps, 13 reuse pipelines, 14 strainers, 15 ultraviolet ray disinfectors, 16 blowdown pipelines, 17 collecting pits, 18 sludge pumps, 19 outlets of sewer
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Rainwater collecting and treating system of the present utility model as shown in Figure 1, comprises the grid pond 1, drainage tank 4, the combination of PP module collecting pit 6, strainer 14 and the ultraviolet ray disinfector 15 that by pipeline, are linked in sequence.
Rainwater is by the pipe network grid pond of flowing through, and the other end with respect to water inlet in this grid pond is obliquely installed artificial grid 3, and the impurity that artificial grid 3 is greater than 5mm by particle diameter in rainwater is held back, and the rainwater that has then been trapped impurity flows into drainage tank 4 by pipeline.In drainage tank, arrange overflow weir and/bleed off pipe 5, collection at rainwater utilizes in process, the water quality of initial rainfall is poor, the abandoned stream of rainwater adopts the synchronous abandoned stream mode of overflow weir formula, abandoned stream, overflowing rain water enter sewage collecting pool, the clean rainwater of rainfall intermediary and later stages enters pipeline, flows to PP module combination collecting pit 6.In PP module combination collecting pit, interval arranges blowdown manhole 8 and reuse manhole 11; The dredge pump 9 in the shaft bottom of blowdown manhole is sent into sewage collecting pool 17 by the sewage that enters blowdown manhole by blow-off line 10; The lift pump 12 in the shaft bottom of reuse manhole pumps into strainer 14 by the rainwater that enters reuse manhole by reuse pipeline 13; Through the filtration of strainer, the rainwater of purification by the pipeline ultraviolet ray disinfector 15 of flowing through, carry out disinfection by ultraviolet light process after reuse, the rainwater of reuse can be for such as greening water etc.
In this example, the pond body of PP module combination collecting pit is processed with impermeable composite geomembrane, to prevent the seepage of the rainwater of Chi Tizhong.
In this example, pipeline used all adopts PE pipe, and anticorrosion antiwear performance is good, long service life.
In this example, PP module combination collecting pit 6 is provided with backwashing system, and the water in PP module combination collecting pit is carried out after backwash, and the water after backwash enters blowdown manhole 8, and drains into sewage collecting pool 17 through dredge pump 9.
Strainer is after operation a period of time, and the pollutant of holding back can stop up the space of filtrate, and disposal ability declines, and therefore needs regularly strainer to be carried out to backwash.
In this example, on the pipeline between strainer and ultraviolet ray disinfector, directional control valve is set, by directional control valve, recycle-water is oppositely sent into strainer, strainer is carried out to backwash, and the sewage after backwash institute filter and mud drain into sewage collecting pool 17 through outlet of sewer 19 and the blowdown pipeline 16 of filter.
Above-mentionedly only the specific embodiment of the utility model is illustrated; but be not that protection domain of the present utility model is done to any pro forma restriction; every equivalence of making according to the design spirit in the utility model changes or modifies, and all should think and fall into protection domain of the present utility model.
