Yintoni indima yePolyaluminium Chloride kulimo lwasemanzini?

Ishishini lasemanzini lineemfuno eziphezulu zomgangatho wamanzi, ngoko ke izinto ezahlukeneyo eziphilayo kunye nezinto ezingcolisa amanzi kwi-aquaculture yamanzi kufuneka zinyangwe ngexesha elifanelekileyo. Eyona ndlela yonyango ixhaphakileyo ngoku kukucoca umgangatho wamanziIiflocculants.

Kwimibhobho eveliswa yi-aquaculture industry, kukho iintlobo ezimbalwa zokungcola, utshintsho oluncinci kumxholo, kunye nokusetyenziswa kwe-oksijini ephantsi kwiinkqubo ze-biochemical. Ukuze kuhlangatyezwane neemfuno zemigangatho yokukhutshwa kwamanzi kunye nokuphucula imeko yasemanzini. Ukusetyenziswa kwe-polyaluminium chloride kunokufezekisa umphumo wokucoca umgangatho wamanzi.

Polyaluminium chlorideidlala indima ebalulekileyo kwi-aquaculture kwaye inemisebenzi emininzi:

1. I-PAC inokuphucula ngokukhawuleza umgangatho wamanzi, ukwandisa i-oksijini echithwe emanzini, ukukhusela i-eutrophication.

2. Iyakwazi ukususa ezinye iintsholongwane kunye neebhaktheriya ezincanyathiselwe kwindawo eqinileyo kumanzi

3. Xa kukho izinto ezininzi eziphilayo kumzimba wamanzi, indlela yokulungisa i-organic matter kumzimba wamanzi ibaluleke kakhulu, kwaye ukusetyenziswa kwe-polyaluminium chloride kufuneka ibe enye yeendlela ezifanelekileyo.

4. Ukunyangwa kwamanzi omsila wokuzala: Umgangatho wamanzi wenkcubeko yechibi uqulethe ubuninzi bezinto eziphilayo ezifana neentsalela zenkcubeko kunye neentlanzi zentlanzi, ezikhokelela ekunciphiseni ukucaca kwamanzi kunye ne-eutrophication yomgangatho wamanzi. Ukukhutshwa ngokuthe ngqo kuya kubangela ukungcoliseka kwendalo. Oku kufuna ukuba amanzi enkcubeko echibi ahluzwe kwaye ahlanjululwe, aze akhululwe okanye ahlaziywe emva kokufikelela kwimigangatho yokukhupha. Ukusetyenziswa kwe-polyaluminium chloride inokukhawuleza idibanise, idibanise, kwaye idibanise amaqhekeza e-colloidal okunzima ukuwakhupha kwiincinci ezinkulu kunye ne-precipitate emanzini, ukunciphisa kakhulu i-COD kunye ne-BOD yomzimba wamanzi kunye nokuphucula kakhulu ukusebenza konyango lwamanzi omsila.

I-Polyaluminium chloride ilungele amanzi akrwada ee-turbidities ezahlukeneyo zobushushu kunye noluhlu olubanzi lwe-pH.

Kufuneka kuqatshelwe ukuba i-polyaluminium chloride kufuneka isetyenziswe kwisixa esifanelekileyo. Ukusetyenziswa ngokugqithisileyo kukhokelela kwisiphumo esibi se-flocculation kwaye kunokubangela ukuvala iigill zentlanzi kunye ne-shrimp, kwaye ayifanelekanga ukusetyenziswa ixesha elide. Ngexesha elifanayo, xa usebenzisa, kufuneka ulungelelaniswe kunye nokukhutshwa kwamanzi amdaka ukukhupha i-agglomerates ye-polyaluminium chloride ngaphandle kwechibi ukuze kufezekiswe ukususwa ngokusisigxina.
