Kushandiswa kwegeomembrane inodzivirira kuyerera kwemvura mumadziva ehove nemadziva ekurima hove

Matanda emvura mudziva rehove, matanda emvura mudziva uye matangi emvura anodzivirira mvura kupinda mumvura zvese zvinoshandiswa zvakanyanya mumapurojekiti ekuchengetedza mvura nekuchengetwa kwemvura, uye ane hunhu hwakasiyana uye mamiriro ekushandiswa.

Ndezvipi zvinoshandiswa chaizvo pakugadzira ma membrane emumadziva ekuberekesa hove, ma membrane emumvura uye ma geomembrane emumadziva asingadonhedze mvura mumapurojekiti ekuchengetedza mvura nekuchengetwa kwehove?

Ndezvipi zvinhu zvinofanira kutariswa panguva yekuisa nekunamira ma membrane ekuberekesa hove mudziva, ma membrane ekuchengetwa kwehove uye ma geomembranes asingadonhedze mvura mudziva?

1.Kamudzira ketsika yedziva rehove：

• Kamudzira kekuchengetera hove mudziva kanonyanya kushandiswa pakuvaka nekugadzirisa madziva ehove. Basa rayo guru nderekudzivirira kudonha kwemvura mumadziva ehove uye kuchengetedza hunhu hwemvura hwakagadzikana.
• Mafirimu akadaro anowanzo gadzirwa ne polyethylene ine density yakakura (HDPE) Yakagadzirwa nezvimwe zvinhu, ine resistance yakanaka yekukwegura, resistance ye ultraviolet uye chemical stability.
• Matanda ehove anogonawo kugadziriswa zvichienderana nezvinodiwa nemadhamu ehove, zvakaita sehukobvu hwakasiyana, saizi nemavara, nezvimwewo.

2.Matanda ekurima gungwa：

• Chidzitiro chekurima gungwa chinoshandiswa zvakanyanya mukuvaka madziva ekuchengetwa kwemvura, macofferdams nedzimwe nzvimbo. Chinangwa chikuru ndechekupa nzvimbo yakanaka yekuchengetwa kwemvura uye kudzivirira kusvibiswa kwemvura uye kubuda kwemvura.
• Kamudzira aka kakagadzirwawo nezvinhu zvakaita se polyethylene ine huwandu hwakawanda, iyo ine hunhu hwakanaka hwekudzivirira mvura, inodzivirira ngura uye inogara kwenguva refu.
• Matanda ekurima mumvura anogonawo kugadziriswa zvichienderana nezvinodiwa zvakasiyana zvemhando dzekurima nenzvimbo dzekurima, zvakaita sekuwedzera mishonga inorwisa mabhakitiriya, mishonga inorwisa algae, nezvimwewo.

3.Geomembrane inodzivirira kubuda kwemvura yedziva：

• Mudziyo wemvura unodzivirira mvura kupinda mumvura unonyanya kushandiswa pakuvaka mapurojekiti ekuchengetedza mvura akadai sematangi emvura nematangi emvura. Basa rawo guru nderekudzivirira kubuda kwemvura uye kuvandudza kushanda zvakanaka uye kuchengetedzeka kwemapurojekiti ekuchengetedza mvura.
• Mafirimu akadaro anowanzo gadzirwa ne polyethylene ine density yakakura, polyvinyl chloride (PVC) Uye nezvimwe zvinhu, zvine simba rakanaka rekudzivirira mvura, simba rekudhonza uye kugara kwenguva refu.
• Munguva yekuvaka, hunhu hwekuisa uye hunhu hwekunamira kwegeomembrane isingapindi mvura yedhamu zvinofanirwa kutariswa kuti zvive nechokwadi chekuti haipindi mvura.

Muchidimbu, ma membrane emvura mudziva rehove, ma membrane emvura mudziva uye ma geomembrane emvura mudziva anodzivirira kunyura kwemvura zvese zvirongwa zvakakosha zvekuchengetedza mvura uye zvinhu zvekurimwa kwemvura zvine hunhu hwakasiyana uye mamiriro ekushandiswa. Pakusarudza nekushandisa zvinhu izvi, kufungwa kwakazara kunofanirwa kuitwa zvichienderana nezvinodiwa chaizvo nemamiriro chaiwo ezvinhu.
