Impompo yamanzi amdaka engaphantsi komhlaba esemgangathweni olungileyo - isixhobo sokuphakamisa esahlula ioyile – Liancheng

Isishwankathelo

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).

ISICELO:
I-oyile yokwahlulahlula ioyile isetyenziswa kakhulu kwiindawo ezinkulu zokuthenga, izakhiwo zeeofisi, izikolo, iiyunithi zomkhosi, zonke iintlobo zeehotele, iindawo zokutyela, iindawo zokutyela zokuzonwabisa zabantu 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 e-oyile nawo ayasetyenziswa.
