Detailed description of the invention:
Below the specific embodiment of the present invention is described in detail.
Specific embodiment 1
As depicted in figs. 1 and 2, a kind of town-property system for reclaiming rainwater, comprise safe shunting well, Split-flow Control device, combined-flow strainer and reservoir, the external rainwater conflux pipe 10 of safe shunting well, safe shunting well is communicated with Storm Sewer Network by abandoned stream pipe 20, safe shunting well is connected with Split-flow Control device by rainwater collection collector 30, Split-flow Control device is connected with combined-flow strainer by pipeline, combined-flow strainer is communicated with reservoir by pipeline, reservoir be provided with bleed off pipe higher than reservoir water water surface 50mm place, bleed off pipe is communicated with Storm Sewer Network by pipeline.
In the present embodiment, rainwater conflux pipe 10 is consistent with the absolute altitude of abandoned stream pipe 20, and the absolute altitude of rainwater collection collector 30 is lower than abandoned stream pipe 200mm.
In the present embodiment, the caliber of rainwater collection collector 30 is not more than the caliber of rainwater conflux pipe 10.
In the present embodiment, the caliber of rainwater conflux pipe is 200mm;
In the present embodiment, rainwater collection collector 30 is connected by bell socket with Split-flow Control device.
In the present embodiment, the bottom of Split-flow Control well is located at by Split-flow Control device, and the external switch board of Split-flow Control device, switch board is located at earth's surface.
In the present embodiment, the bottom of combined-flow filter well is located at by combined-flow strainer.
As shown in Figure 2, the top of safe shunting well is provided with well lid 41.
During use, early-stage rainwater is mingled with a large amount of dust and silt, and water quality is poor, answers abandoned stream to rain-water drainage pipeline, is that limpid rainwater carries out collection storage to the later stage.General rain water on roof for boundary, carries out abandoned stream and collection with initial stage 2 ~ 3mm rainfall runoff.When rain water reservoir reaches high water level, should stop collecting, abandoned stream is carried out to unnecessary amount of rainfall.
Safe shunting well:
Safe shunting well is for connecting rainwater conflux pipe, rainwater collection collector and abandoned stream pipe, and rainwater catchment pipe is identical with abandoned stream pipe absolute altitude, higher than rainwater collection collector.
At the rainfall initial stage, Split-flow Control device cuts out, and early-stage rainwater directly enters rain-water drainage pipe network through abandoned stream pipe; When Split-flow Control device is opened, rainwater enters combined-flow strainer by rainwater collection collector, then enters reservoir.When reservoir reaches high water level, Split-flow Control device cuts out.Rainwater collection collector calculates according to the storm intensity of 1 year recurrence interval.
Split-flow Control device:
Split-flow Control device front end has grid, and for tackling bulky grain suspension, interval of grid strip 3mm, takes out basket grid after rain stops and topple over.Split-flow Control device is generally installed on outdoor underground, and now attach control cabinet and need more than 300mm above ground level, control cabinet has rain sensor, needs outdoor installation.Split-flow Control device, without the need to Artificial Control, carries out multi-point signal Monitoring and Controlling by inside PLC control program, and carries out memory process to the rainfall pattern, the frequency, rainfall, pH value etc. of rainfall, according to test data adjustment abandoned stream time and flow, collects high-quality rainwater.
Be bell socket between Split-flow Control device and rainwater collection collector, and determine according to rainwater collection collector caliber.
Combined-flow strainer:
Combined-flow strainer adopts the combined-flow principle of baffling, reverse flow, uninterruptedly carries out separating and filtering to rainwater.Equipment precision is 1mm, without the need to manual operation, does not establish backwash process.
Be bell socket between combined-flow strainer and rainwater collection collector, and determine according to rainwater collection collector caliber.
Reservoir:
Rain water reservoir adopts reinforced concrete structure, and be arranged at outdoor underground, reservoir should arrange inspection hole, bleed off pipe, the facilities such as ventilating pipe, sewage pressure device for transferring, and reservoir lowest part arranges sludge sump simultaneously, answers slope aspect sludge sump at the bottom of pond.
The subsidiary control cabinet of Split-flow Control device, inside PLC controls with Non-follow control dual-purpose automatically, can and system master cabinet between perform distant communication, abandoned stream mode of operation can be shown in main control cabinet man-machine interface, there is fault alarm function.Rain water drainage control program is multi-point signal programme-control, and its principle is as follows:
Conventional method obtains abandoned stream signal: when being started by rainfall, and record amount of precipitation, when it reaches 2 ~ 5mm, start to record the concentration time, when after the rainwater catchment time that it reaches according to distance setting of confluxing, abandoned stream process terminates, open Split-flow Control device flashboard, allow rainwater to pass through.
Frequently determine the abandoned stream time according to rain: by the end of rainfall, stop to during second time rainfall, record rainfall interval, when it is less than 24h, skips abandoned stream process, directly collects rainwater.
According to the Rainwater Quality determination abandoned stream time: when rainwater passes through the water quality sensor in safe shunting well, record water quality situation, when it drops to below a certain setting value, abandoned stream process terminates.
Reservoir water lev el control: when being in high liquid level in reservoir, closes rain water drainage controller gate, blocks rainwater and enters reservoir.
