Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, a kind of unpowered rainwater reuse device that is applicable to high-rise, comprise first row water pipe 1, water flow indicator 2, PLC automatic control device 3, the first valve 4, the 9th water shoot 5, the 3rd valve 6, the 8th water shoot 7, pressure indicator 8, sandfiltration pot 9, second row water pipe 10, the 4th valve 11, the 3rd water shoot 12, hyperfiltration membrane assembly 13, bracket 14, the 4th water shoot 15, the 5th valve 16, the 5th water shoot 17, the 6th valve 18, the 6th water shoot 19, the 7th water shoot 20, the 8th water shoot 21, the 9th water shoot 22, the tenth water shoot 23.
In this system rainwater treating processes, have bi-level treatment device, wherein coagulation device is mainly used in away the most of impurity in rainwater, comprises larger particulate matter.Coagulation device is comprised of two portions: comprise first part---early-stage rainwater stream abandoning device and second section---sandfiltration pot; Second-stage treatment device is polysulfone hollow fiber ultrafiltration membrane system, for to the further purifying treatment of rainwater, makes water outlet reach respective country standard.The rainwater that roof is collected enters system from first row water pipe 1, because early-stage rainwater contains more impurity, be unfavorable for the steady running of aftertreatment device, thus it is carried out to abandoned stream, when water flows through water flow indicator, water flow indicator produces electrical signal and passes to PLC automatic control device 3 by circuit, by default program, PLC automatic control device is controlled the first valve 4 and is opened, and the 3rd valve 6 is closed, make early-stage rainwater obtain abandoned stream, to guarantee the water quality of water inlet.After ten minutes, same under the time variable control of PLC automatic control device, the first valve 4 is closed, and the 3rd valve 6 is opened, early-stage rainwater stream abandoning end of processing.Meanwhile, rainwater enters sandfiltration pot 9, and quartz sand thickness is 800mm, particle diameter 0.8-1.2mm, and in sandfiltration pot, under the filtration of quartz sand, rainwater obtains rough purification, filtering larger particles, and enter the second-stage treatment device in system---in hyperfiltration membrane assembly.When hydraulic pressure does not reach membrane module operating pressure, rainwater can not see through hyperfiltration membrane assembly, so rainwater starts to accumulate in pipeline.(the 0.1-0.5Mpa when pressure of water column reaches the pressure range of hyperfiltration membrane assembly work in water shoot, amount to into water column and be about 10 meters-50 meters), membrane module is started working, the many tiny micropore gathering in ultra-filtration membrane surface only allows water and small-molecule substance by becoming through liquid, the material that in rainwater, particle diameter is greater than film surface micropore footpath is trapped within the liquid feeding side of film, becomes concentrated solution.Wherein see through liquid by the 5th water shoot 17, the 6th valve 18, the 7th water shoot 20 outputs, concentrated solution is discharged, thereby is realized rain water purification, separation and concentrated object through the 4th water shoot 15, the 5th valve 16, the 6th water shoot 19.Through the bi-level treatment process of native system, rainwater can be processed to the standard reaching in < < urban sewage reutilization city miscellaneous water water quality (GB/T18920-2002) > >.When needs carry out back flushing to membrane module, close the 4th valve 11, open the 6th valve 18 and the 5th valve 16, scavenging solution enters from the 7th water shoot 20, the 5th water shoot 17, and the concentrated solution after back flushing is discharged from the 4th water shoot 15, the 6th water shoot 19.In the technological process of native system, realize the automatic flow abandoning of early-stage rainwater, save manpower, operational efficiency is high; At membrane module, process in rainwater process, its operating pressure comes from the pressure that water column that rainwater accumulates in water shoot produces completely, without extra power, realizes energy-saving and cost-reducingly, has stronger economic worth.
