Imishini yokuhlanza indle yokucubungula emanzini

Imithombo yamanzi angcolile acutshungulwa emanzini

Inqubo yokukhiqiza: ukuncibilika kwempahla eluhlaza → inhlanzi esikiwe → ukuhlanza → ukulayishwa kwepuleti → ukuqhwaza okusheshayo Impahla eluhlaza encibilikisiwe eqandisiwe, ukugeza amanzi, ukulawula amanzi, ukubulala amagciwane, ukuhlanza nezinye izinqubo kukhiqiza amanzi angcolile okukhiqiza, Izinto ezingcolisa kakhulu ezikhishwa emanzini okugeza emishini yokukhiqiza futhi indawo yokusebenzela yi-CODcr, BOD5, SS, ammonia nitrogen, njll.

Ubuchwepheshe benqubo yokwelapha ngaphambilini

Ngenxa yokungalingani kokukhishwa kwamanzi angcolile okucubungula emanzini kanye nokushintshashintsha okuphawulekayo kwekhwalithi yamanzi, kuyadingeka ukuqinisa izinyathelo zokwelashwa kwangaphambili ukuze kuzuzwe imiphumela ezinzile yokwelapha.Amanzi angcolile abanjwa igridi ukuze akhiphe izinhlayiya emanzini, futhi izinto eziqinile ezimisiwe njengesikhumba senhlanzi, ukushefa kwenyama, namathambo ezinhlanzi ziyahlukaniswa ngaphambi kokungena ethangini elilawulayo.Kufakwe idivayisi yokungenisa umoya ethangini, enemisebenzi efana nokuqeda iphunga nokusheshisa ukuhlukaniswa kukawoyela emanzini angcolile, ukuthuthukisa ukubola kwemvelo kwamanzi angcolile kanye nokuqinisekisa ukusebenza ngempumelelo kokwelashwa okulandelayo kwebhayoloji.Ngenxa yobuningi bamafutha emanzini angcolile, imishini yokukhipha uwoyela kufanele ifakwe.Ngakho-ke inqubo yokwelashwa kwangaphambili ihlanganisa: i-grating kanye negumbi lokuphakamisa, ithangi le-air flotation, ithangi le-hydrolysis acidification.

Icubungula isidingo

1. Ikhwalithi yokulahlwa kwezinga lokulahla indle ihlangabezana nezinga lezinga lokuqala elishiwo “Izinga Eliphelele Lokukhipha Amanzi Angcolile” (GB8978-1996).

2. Izidingo zobuchwepheshe:

① Inqubo * *, ethembekile ngokobuchwepheshe, nesixazululo esilungiselelwe umnotho siyadingeka.Isakhiwo esiphusile nesigxivizo sonyawo esincane siyadingeka.

② Izinsiza eziyinhloko zesiteshi sokukhucululwa kwendle zisebenzisa isakhiwo sikakhonkolo sensimbi esingaphezu komhlaba.

③ Amanzi angenayo axhunywe ngepayipi likakhonkolo, elinokuphakama okungaphansi kuka -2.0m.Ngemva kokudlula emthonjeni wokulinganisa amanzi, amanzi afakwa epayipini likamasipala elingaphandle kwendawo yefekthri.

Izinga lokuqala lezinga elicaciswe “Kuzinga Eliphelele Lokukhipha Amanzi Angcolile” (GB8978-1996): iyunithi: mg/L okuqinile okumisiwe SS ＜ 70;BOD＜ 20;I-COD <100;I-ammonia nitrogen <15.
