Amanzi angcolile avela kwezolimo kanye nokucubungula ukudlainezici ezibalulekile eziwahlukanisa namanzi angcolile kamasipala ajwayelekile aphethwe yizindawo zokuhlanzwa kwamanzi angcolile zomphakathi noma ezizimele emhlabeni jikelele: ayabola futhi awanabo ubuthi, kodwa anesidingo esiphezulu se-oxygen yezinto eziphilayo (BOD) kanye nezinto eziqinile ezimisiwe (SS).Ukwakheka kwamanzi angcolile okudla nakwezolimo kuvame ukuba nzima ukubikezela ngenxa yomehluko kumazinga e-BOD kanye ne-pH emanzini angcolile asuka emikhiqizweni yemifino, izithelo nenyama, kanye nezindlela zokucubungula ukudla kanye nesikhathi sonyaka.
Kudingeka amanzi amaningi amahle ukucubungula ukudla okuvela ezintweni ezingavuthiwe.Ukugeza imifino kukhiqiza amanzi aqukethe i-particle eningi kanye ne-organic matter encibilikisiwe.Ingase futhi ibe nama-surfactants nezibulala-zinambuzane.
Izakhiwo ze-aquaculture (amapulazi ezinhlanzi) ngokuvamile zikhipha inani elikhulu le-nitrogen ne-phosphorus, kanye nezinto eziqinile ezimisiwe.Ezinye izikhungo zisebenzisa izidakamizwa nezibulala-zinambuzane okungenzeka zibe khona emanzini angcolile.
Izitshalo zokukhiqiza ubisi zikhiqiza ukungcola okujwayelekile (BOD, SS).
Ukuhlatshwa kwezilwane kanye nokucubungula kukhiqiza udoti wemvelo ophuma oketshezini lomzimba, njengegazi kanye nokuqukethwe kwamathumbu.Izinto ezingcolisayo ezikhiqizwayo zifaka i-BOD, i-SS, i-coliform, uwoyela, i-organic nitrogen, ne-ammonia.
Ukudla okugayiwe okudayiswayo kudala imfucuza ekuphekeni, okuvamise ukunotha ngezinto eziphilayo zezitshalo futhi kungaqukatha nosawoti, okokunandisa, okokufaka imibala nama-asidi noma izisekelo.Kungase futhi kube nenani elikhulu lamafutha, amafutha kanye nama-greases (” FOG “) okuthi ekugxilweni okwanele kungavala imisele.Amanye amadolobha adinga izindawo zokudlela kanye nabacubungula ukudla ukuthi basebenzise izivimba zamafutha futhi balawule ukuphathwa kwe-FOG ezinhlelweni zendle.
Imisebenzi yokucubungula ukudla njengokuhlanza izitshalo, ukuphatha impahla, ukufaka amabhodlela nokuhlanza imikhiqizo kukhiqiza amanzi angcolile.Izikhungo eziningi zokucubungula ukudla zidinga ukwelashwa endaweni ngaphambi kokuthi amanzi angcolile asetshenziswe emhlabeni noma akhishelwe emgwaqeni wamanzi noma ohlelweni lwendle.Amazinga aphezulu okuqinile amisiwe ezinhlayiya eziphilayo angakhuphula i-BOD futhi angaholela ekukhokhisweni okuphezulu kwendle.I-Sedimentation, izikrini ezimise okwe-wedge, noma ukuhlungwa komcu ojikelezayo (i-microsieving) izindlela ezivame ukusetshenziswa ukunciphisa umthwalo wezinto eziphilayo ezimisiwe ezimisiwe ngaphambi kokuthi zikhishwe.I-Cationic high-efficiency high-efficiency separator yamanzi kawoyela nayo ivame ukusetshenziswa ekuhlanzeni indle okunamafutha esitshalweni sokudla (isihlukanisi samanzi samafutha esisebenza kahle kakhulu esiqukethe amakhemikhali e-anionic noma izinhlayiya ezikhokhiswa kabi zendle noma amanzi angcolile, kungakhathaliseki ukuthi isetshenziswa yodwa noma ngokusetshenziswa kwenhlanganisela ye-coagulant ye-inorganic coagulant, ingakwazi. finyelela ukuhlukana okusheshayo, okuphumelelayo noma ukuhlanzwa kwezinjongo zamanzi.Isihlukanisi sikawoyela esisebenza kahle kakhulu nesihlukanisi samanzi sinomphumela we-synergistic, singasheshisa isivinini se-flocculation, sinciphise izindleko zokusebenzisa imikhiqizo).
