Amanzi amdaka asuka kwezolimo kunye nokulungiswa kokutyaineempawu ezibalulekileyo eziyahlula kumanzi amdaka kamasipala aqhelekileyo alawulwa zizityalo zikawonke-wonke okanye zabucala zokucocwa kwamanzi amdaka kwihlabathi jikelele: ayabola kwaye ayinayo ityhefu, kodwa anemfuno ephezulu yebhayoloji yeoksijini (BOD) kunye nezinto eziqinileyo (SS). Ukubunjwa kokutya kunye namanzi amdaka ezolimo kudla nzima ukuqikelela ngenxa yokungafani kwe-BOD kunye namanqanaba e-pH kumanzi amdaka avela kwimifuno, iziqhamo kunye nemveliso yenyama, kunye neendlela zokulungisa ukutya kunye nexesha lonyaka.
Kuthatha amanzi amaninzi alungileyo ukucubungula ukutya okuvela kwimathiriyeli ekrwada. Ukuhlamba imifuno kuvelisa amanzi aqulethe i-particle eninzi kunye ne-organic matter enyityilisiweyo. Isenokuba ne-surfactants kunye nezibulali zinambuzane.
Izibonelelo ze-aquaculture (iifama zeentlanzi) zihlala zikhupha izixa ezikhulu zenitrogen kunye ne-phosphorus, kunye nezinto eziqinileyo ezinqunyanyisiweyo. Ezinye iindawo zisebenzisa iziyobisi kunye nezibulali-zinambuzane ezinokuthi zibekho kumanzi amdaka.
Izityalo zokwenziwa kobisi zivelisa ungcoliseko oluqhelekileyo (BOD, SS).
Ukuxhelwa kwezilwanyana kunye nokusebenza kuvelisa inkunkuma evela kulwelo lomzimba, njengegazi kunye namathumbu. Izinto ezingcolisayo eziveliswayo ziquka i-BOD, i-SS, i-coliform, i-oyile, i-nitrogen ephilayo, kunye ne-ammonia.
Ukutya okucutshungulweyo okuthengisiweyo kudala inkunkuma ekuphekeni, ehlala ityebile kwizinto zezityalo-eziphilayo kwaye isenokuba neetyuwa, iziqholo, izinto ezifaka imibala kunye neeasidi okanye iziseko. Kusenokubakho izixa ezikhulu zamafutha, ioyile kunye negrisi (” FOG “) ekugxininiseni okwaneleyo kunokuvala imijelo. Ezinye izixeko zifuna iindawo zokutyela kunye nabalungisi bokutya ukuze basebenzise izithinteli zegrisi kunye nokulawula ukuphathwa kweFOG kwiinkqubo zogutyulo.
Imisebenzi yokulungisa ukutya efana nokucoca izityalo, ukuphatha imathiriyeli, ukufaka iibhotile kunye nokucoca imveliso kuvelisa amanzi amdaka. Uninzi lweendawo zokulungisa ukutya zifuna unyango kwindawo phambi kokuba amanzi amdaka asebenzayo asetyenziswe emhlabeni okanye akhutshelwe kumgaqo wamanzi okanye kwindlela yogutyulo. Amanqanaba aphezulu ezinto eziqinileyo ezinqunyanyisiweyo zamasuntswana aphilayo anokunyusa iBOD kwaye anokubangela intlawulo eyongezelelweyo yomjelo ophantsi komhlaba. I-Sedimentation, i-wedge-shaped screens, okanye i-roting strip filtration (microsieving) ziindlela eziqhelekileyo ezisetyenziswayo zokunciphisa umthwalo wezinto eziphilayo ezimisiweyo ngaphambi kokukhutshwa. I-Cationic high-efficiency high-efficiency oil-water separator ikwahlala isetyenziswa kwisityalo sokutya ukucocwa kogutyulo lwelindle (i-high-effective high-efficiency oil-water separator equlathe imichiza ye-anionic okanye amasuntswana ahlawuliswa kakubi elindle okanye amanzi amdaka, nokuba isetyenziswa yodwa okanye ngokusetyenziswa kwekhompawundi ye-inorganic coagulant. ukufezekisa ukwahlukana okukhawulezayo, okusebenzayo okanye ukucocwa kweenjongo zamanzi eziphezulu ze-oyile kunye ne-separator yamanzi ine-synergistic effect, inokukhawulezisa isantya se-flocculation, ukunciphisa iindleko zokusebenzisa iimveliso).
