isixhobo sokuphakamisa esahlula ioyile

Inkcazo emfutshane:

Amanzi amdaka aneoyile phantsi kwesenzo somxhuzulane, umahluko phakathi kwenani leoyile namanzi, ukususwa kokwahlulwa kwendalo kokudada emanzini amdaka e-oyile kunye nenxalenye yokuqhekeka kweoyile enkulu. Ezi ngxaki zintathu, ziphucula umsebenzi wokwahlulwa kweoyile namanzi, umgaqo wokwahlulwa kokujika kunye nolwalamano oluguquguqukayo lwe-laminar dialectical phakathi kokusetyenziswa kunye namanzi amdaka ahamba ngokwahlulahlula amanzi amdaka, inkqubo inciphisa izinga le-f10w kunye nokwanda kwecandelo lamanzi ukuze kuncitshiswe izinga lokuhamba (ngaphantsi okanye lilingane ne-0.005m/s), kwandisa ixesha lokugcina amanzi amdaka, kwaye kwenze lonke icandelo lihambe ngokulinganayo. Yenza indawo yamanzi ikwaqwalasele ngokupheleleyo ukufana kokuhamba kunye nokususa ivumba kunye nemilinganiselo yokulwa nesiphon. Ukuziqhelanisa kuye kwabonisa ukuba imveliso ingakwazi ukususa ngaphezulu kwe-90% ye-oyile etyibilikayo, amanzi amdaka akhutshwe kumxholo oguqukayo weoyile yemifuno aphantsi kunowomgangatho wesithathu we "umgangatho wokukhutshwa kwamanzi amdaka adibeneyo" (GB8978-1996) (100mg/L).

Isishwankathelo

Amanzi amdaka aneoyile phantsi kwesenzo somxhuzulane, umahluko phakathi komlinganiselo weoyile namanzi, ukususwa kokwahlulwa okudadayo kwendalo emanzini amdaka ee-oyile ezityibilikayo kunye nenxalenye yokuqhekeka kweoyile enkulu. Ezi ngxaki zintathu ziphucula umsebenzi wokwahlulwa kweoyile namanzi.，umgaqo wokwahlulwahlulwa kokuphambuka kunye nolwalamano oluguquguqukayo lwe-laminar turbulent dialectical phakathi kokusetyenziswa kunye namanzi amdaka ahamba ngomhluzi wamanzi anamafutha，inkqubo, nciphisa isantya se-f10w kwaye ngokwandisa icandelo lamanzi ukuze kuncitshiswe isantya sokuhamba kwamanzi (ngaphantsi okanye esilingana ne-0.005m/s)，Yandisa ixesha lokugcina amanzi amdaka, kwaye wenze lonke icandelo lihambe ngokulinganayo. Yenza indawo yamanzi iqwalasele ngokupheleleyo ukufana kokuhamba kwayo kunye nokususa ivumba kunye nemilinganiselo yokulwa nokuphonswa. Isenzo sibonakalise ukuba imveliso enobubanzi beenkozo ezingama-60um ngaphezulu inokususa ngaphezulu kwe-90% ye-oyile etyibilikayo, amanzi amdaka akhutshwa kumxholo oguqukayo weoyile yemifuno aphantsi kunalawo esithathu.umgangatho weklasi "womgangatho wokukhupha amanzi amdaka adibeneyo" (GB8978-1996) (100mg/L).

ISICELO：
Isihluzi seoyile sisetyenziswa kakhulu kwiindawo ezinkulu zokuthenga, izakhiwo zeeofisi, izikolo, iiyunithi zomkhosi.，Zonke iintlobo zeehotele, iivenkile zokutyela, iindawo zokutyela zolonwabo lwabantu abadala kunye nezoshishino, ungcoliseko lwegrisi ye-drain yekhitshi, sisixhobo esibalulekileyo segrisi yekhitshi, kunye netyhubhu yokukhupha amanzi egaraji ethintela izixhobo ezifanelekileyo zeoyile. Ukongeza, amanzi amdaka okugquma amashishini kunye namanye amanzi amdaka aneoyile nawo ayasetyenziswa.

Emva kweminyaka engamashumi amabini yophuhliso, eli qela libambe iipaki zemizi-mveliso ezintlanu kwiindawo zaseShanghai, eJiangsu naseZhejiang njl.njl. apho uqoqosho luye lwaphuhliswa kakhulu, lugubungela umhlaba wonke ongama-550 amawaka eemitha zesikwere.
