Isifundo seTyala leSitishi sokuNyanga aManzi amdaka kwiSithili saseXi'an, kwiPhondo laseShaanxi

II. Iteknoloji yeNkqubo kunye neMigangatho yokuNgcola
Esi sakhiwo sisebenzisa ubuchwepheshe obuphambili bokucoca amanzi amdaka, sisebenzisa kakhulu inkqubo yodaka olusebenzayo lweSequencing Batch Reactor (SBR). Le ndlela inika ukusebenza kakuhle konyango, ukuguquguquka kokusebenza, kunye nokusetyenziswa kwamandla aphantsi, okuvumela ukususwa ngokufanelekileyo kwezinto eziphilayo, i-nitrogen, i-phosphorus, kunye nezinye izinto ezingcolisayo. Ukungcola okucociweyo kuhambelana neemfuno zeBanga A ezichazwe kwi "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants" (GB18918-2002). Amanzi akhutshiweyo acacile, akanavumba, kwaye ahlangabezana nazo zonke iikhrayitheriya ezilawulayo zokusingqongileyo, ezivumela ukukhutshwa ngokuthe ngqo emanzini endalo okanye ukuphinda kusetyenziswe kwakhona kwiindawo zokulima zasezidolophini kunye neempawu zamanzi ezintle.

III. Iingenelo zokusingqongileyo kunye neminikelo yoluntu
Ukusebenza ngempumelelo kwesi sityalo sokucocwa kwamanzi amdaka kuyiphucule kakhulu imeko-bume yamanzi asezidolophini eXi'an. Sidlala indima ebalulekileyo ekulawuleni ungcoliseko, sikhusela umgangatho wamanzi esitratweni semilambo yasekuhlaleni, kwaye sigcina ulungelelwaniso lwendalo. Ngokuphatha kakuhle amanzi amdaka kamasipala, esi sakhiwo sinciphise ungcoliseko lwemilambo namachibi, saphucula iindawo zokuhlala emanzini, kwaye sanegalelo ekubuyiselweni kwenkqubo yendalo. Ngaphezu koko, esi sityalo siphucule imeko-bume yotyalo-mali yesixeko, satsala amashishini ongezelelweyo kwaye saxhasa uphuhliso loqoqosho oluzinzileyo lwengingqi.
