Ukukhuphulaizimfanzi, kumele ukhuphule amanzi kuqala.Kuyo yonke inqubo yokukhulisa izimfanzi, ukulawulwa kwezinga lamanzi kubaluleke kakhulu.Ukwengeza nokushintsha amanzi kungenye yezindlela ezilula zokulawula ikhwalithi yamanzi.Ingabe ichibi lezimfanzi kufanele lishintshe amanzi?Abanye abantu bathi ama-prawn antekenteke kakhulu.Ukushintsha imigogodla ukuze imidambi ibe igobolondo kuvame ukwenza buthaka umzimba wayo futhi ijwayele ukungenwa izifo.Abanye bathi akunakwenzeka ukuthi ungawashintshi amanzi.Ngemuva kwesikhathi eside sokukhushulwa, izinga lamanzi li-eutrophic, ngakho-ke kufanele siguqule amanzi.Ingabe kufanele ngishintshe amanzi lapho ngikhulisa izimfanzi?Noma ngaphansi kwaziphi izimo amanzi angashintshwa futhi ngaphansi kwaziphi izimo amanzi angeke ashintshwe?

 

Kuzohlangatshezwana nemibandela emihlanu yokushintsha amanzi ngendlela efanele

1. Imidambi ayikho esikhathini esiphezulu seukubhoboza, futhi umzimba wabo ubuthakathaka kulesi sigaba ukugwema ukucindezeleka okukhulu;

2. Imidambi inomzimba onempilo, amandla amahle, ukudla okunamandla futhi ayinaso isifo;

3. Umthombo wamanzi uqinisekisiwe, izimo zekhwalithi zamanzi aphesheya kwezilwandle zinhle, izinkomba ezibonakalayo namakhemikhali zijwayelekile, futhi kunomehluko omncane kusuka kusawoti kanye nezinga lokushisa lamanzi echibini lezimfanzi;

4. Umzimba wamanzi echibini lokuqala unokuzala okuthile, futhi ulwelwe lunamandla ngokuqhathaniswa;

5. Amanzi okungena ahlungwa nge-mesh eminyene ukuze kuvinjelwe ngokuqinile izinhlanzi zasendle ezixubile nezitha ukuthi zingangeni echibini lezimfanzi.

Indlela yokukhipha nokushintsha amanzi ngokwesayensi esigabeni ngasinye

1) Isigaba sokuqala sokuzalanisa.Ngokuvamile, amanzi kuphela anezelwa ngaphandle kwe-drainage, engathuthukisa izinga lokushisa lamanzi ngesikhathi esifushane futhi ihlakulele izinto eziphilayo ezanele zokudoba kanye ne-algae enenzuzo.

Lapho wengeza amanzi, angase ahlungwe ngezingqimba ezimbili zezikrini, anezikhala ezingu-60 zongqimba lwangaphakathi kanye nezikhala ezingu-80 zongqimba olungaphandle, ukuze kuvinjwe izinto eziphila ezitheni namaqanda ezinhlanzi ukuthi zingangeni echibini lezimfanzi.Engeza amanzi 3-5cm nsuku zonke.Ngemuva kwezinsuku ezingama-20-30, ukujula kwamanzi kancane kancane kungafinyelela ku-1.2-1.5m ukusuka ekuqaleni kuka-50-60cm.

2) Ukuzalanisa isikhathi esimaphakathi.Ngokuvamile, lapho umthamo wamanzi udlula u-10cm, akufanelekile ukushintsha isikrini sokuhlunga ukuze ususe ukungcola nsuku zonke.

3) Isigaba sakamuva sokuzalanisa.Ukuze ukwandise umoya-mpilo oncibilikisiwe ongqimbeni olungezansi, amanzi echibi kufanele alawulwe ku-1.2m.Kodwa-ke, ngoSepthemba, izinga lokushisa lamanzi laqala ukwehla kancane kancane, futhi ukujula kwamanzi kungandiswa ngokufanele ukuze kugcinwe izinga lokushisa lamanzi njalo, kodwa ukushintsha kwamanzi nsuku zonke akufanele kudlule u-10cm.

Ngokungeza nokushintsha amanzi, singakwazi ukulungisa usawoti kanye nokuqukethwe kwezakhi zamanzi echibini lezimfanzi, silawule ukuminyana kolwelwe olungahlangani, silungise ukukhanya, futhi sandise okuqukethwe komoyampilo oncibilikisiwe emanzini echibini lezimfanzi.Esikhathini sokushisa okuphezulu, ukushintsha amanzi kungaphola.Ngokungeza nokushintsha amanzi, i-pH yamanzi echibini lezimfanzi ingasimama futhi okuqukethwe kwezinto ezinobuthi njenge-hydrogen sulfide ne-ammonia nitrogen kungancishiswa, ukuze kuhlinzekwe indawo yokuhlala enhle yokukhula kwezimfanzi.
