idivayisi yokuphakamisa ehlukanisa uwoyela

Incazelo emfushane:

Amanzi angcolile anamafutha ngaphansi kwesenzo sokudonsa phansi, ngomehluko wesilinganiso samafutha namanzi, ukususwa kokuhlukaniswa okuntantayo kwemvelo emanzini angcolile ama-slicks kawoyela kanye nengxenye yokuqhekeka kwamafutha amaningi. Lokhu kuxaka okuthathu, kuthuthukisa umsebenzi wokuhlukaniswa kwamafutha namanzi, isimiso sokuhlukaniswa kokuphambuka kanye nobudlelwano obuguquguqukayo be-laminar dialectical phakathi kokusetshenziswa kanye nokugeleza kwamanzi angcolile ngesihlukanisi samanzi anamafutha, inqubo, yehlisa izinga le-f10w kanye nokwanda kwengxenye yamanzi ukuze kuncishiswe izinga lokugeleza (ngaphansi noma okulingana no-0.005m/s, kwandisa isikhathi sokugcina amanzi angcolile, futhi kwenze ingxenye yonke ibe nokugeleza okufanayo. Yenza indawo yamanzi iphinde icabangele ngokugcwele ukufana kokugeleza kanye nokususa iphunga kanye nezilinganiso zokulwa ne-siphon. Umkhuba ukhombisile ukuthi ububanzi bomkhiqizo obungama-60um ngaphezulu bungasusa okungaphezu kuka-90% kwe-slick kawoyela, amanzi angcolile akhishwa kokuqukethwe okunamandla kawoyela wemifino aphansi kunaleyo yezinga lesithathu le-"integrated water waste discharge standard" (GB8978-1996) (100mg/L).

Amanzi angcolile kawoyela ngaphansi kwesenzo samandla adonsela phansi, ngomehluko wesilinganiso samafutha namanzi, ukususwa kokuhlukaniswa okuntantayo kwemvelo emanzini angcolile okushelela kwamafutha kanye nengxenye yokuqhekeka kwamafutha amaningi. Lokhu kuxaka okuthathu, kuthuthukisa umsebenzi wokuhlukaniswa kwamafutha namanzi，isimiso sokuhlukanisa ukuphambukisa kanye nobudlelwano obuguquguqukayo be-laminar turbulent dialectical phakathi kokusetshenziswa kanye nokugeleza kwamanzi angcolile ngokusebenzisa isihlukanisi samanzi anamafutha，inqubo, nciphisa izinga le-f10w kanye nokwenyuka kwengxenye yamanzi ukuze kuncishiswe izinga lokugeleza (elingaphansi noma elilingana no-0.005m/s，ukwandisa isikhathi sokugcina amanzi amdaka, futhi wenze ingxenye yonke igeleze ngokulinganayo. Yenza indawo yamanzi icabangele ngokugcwele ukufana kokugeleza kanye nokususa iphunga kanye nezinyathelo zokulwa nokuphonswa. Umkhuba ukhombisile ukuthi ithini lomkhiqizo elingama-60um ububanzi ngaphezu kuka-60 lingasusa okungaphezu kuka-90% kokucwila kwamafutha, amanzi amdaka akhishwa kokuqukethwe okuguquguqukayo kwamafutha emifino aphansi kunalawo wesithathu.indinganiso yekilasi "yendinganiso yokukhipha amanzi amdaka ahlanganisiwe" (GB8978-1996) (100mg/L).

ISICELO：
Isihlukanisi samafutha sisetshenziswa kabanzi ezitolo ezinkulu, ezakhiweni zamahhovisi, ezikoleni, emayunithi ezempi，Zonke izinhlobo zamahhotela, izindawo zokudlela, izindawo zokudlela zabantu abadala kanye nezindawo zokudlela zebhizinisi, ukungcola kwamafutha ekhishini, kuyimishini ebalulekile yamafutha ekhishini, kanye nepayipi lokukhipha amanzi egalaji elivimba imishini efanele kawoyela. Ngaphezu kwalokho, amanzi angcolile okumboza izimboni kanye namanye amanzi angcolile anamafutha nawo ayasetshenziswa.

Ngemva kweminyaka engamashumi amabili yentuthuko, leli qembu liphethe amapaki ezimboni amahlanu ezindaweni zaseShanghai, eJiangsu naseZhejiang njll. lapho umnotho uthuthuke khona kakhulu, uhlanganisa indawo yomhlaba engamamitha-skwele ayi-550,000.
