Ngomda wokukhupha "umgangatho wokukhupha i-electroplating pollutant discharge" ngakumbi nangakumbi, ngoku, ukunyangwa kwamanzi amdaka esinyithi kuye kwaba yingqwalasela enkulu yeshishini. Ngoku amanzi amdaka esinyithi ahlala ephathwa anzima kwaye akhululekile, phakathi kwawo, amanzi amdaka esinyithi anetyhefu enamandla, unyango lunzima. Kwaye ngenxa ye-biochemistry ephantsi yolu hlobo lomgangatho wamanzi, ngoko ngoku unyango oluphambili lomzimba kunye neekhemikhali, unyango oluqhelekileyo luthetha ukusetyenziswa kwe-agent eqhekezayo, i-agent enzima yokubamba isinyithi kunye ne-sodium sulfide kunye nolunye unyango lweekhemikhali.

I-sodium sulfide inesiphumo sokwaphulwa kwe-collateral kunye ne-sulfide precipitation yezinto ezingcolisa isinyithi esinzima, kunye nexabiso eliphantsi, ngoko ke ushishino lwangoku lusebenzisa i-sodium sulfide ukunyanga amanzi amdaka esinyithi esinzima. Eli phepha lizisa ngokukodwa ukusetyenziswa kwe-sodium sulfide kunye nokongeza amanyathelo, iinkcukacha zilandelayo.

Enyanisweni, inyathelo elongezelelweyo le-sodium sulfide limiselwa ngokukodwa ngokwemeko yangempela yendawo, oku kulandelayo ngamanyathelo ambalwa okusetyenziswa kwenkqubo yokucoca ugutyulo oluqhelekileyo.

1. I-sodium sulfide yongezwa ekupheleni kwetanki elawulayo. Ngenxa yokuba i-sodium sulfide iyindalo ayikwazi ukusetyenziswa phantsi kweemeko ze-acidic, ngoko ke kuyimfuneko yokongeza i-alkali ngaphambi kokusetyenziswa, ukuze kuthintelwe ukuveliswa kwezinto ezinobuthi ezinobuthi kunye ne-volatilization, kodwa nokuqinisekisa unyango olusebenzayo, kunye nesimo esiyinkimbinkimbi kwaye sikhululekile. Ukusabela kwe-ion yesinyithi kwimvula yesulfide.

2. Yongeza i-sodium sulfide kwitanki yokusabela. Ukuba endle debugging, iimeko zokwenyani, sulfide isodiyam zingongezwa kwindawo eyaphukileyo emva (alkaline) reaction pool, ngenxa yokuba i-ion yesinyithi entsonkothileyo yaphukile ibe yi-ion yesinyithi yasimahla, ngoko ke kwichibi lokusabela emva kokwaphuka kwakhona yongeza unyango lwe-sodium sulfide. luncedo ngakumbi ekuphuculeni isiphumo sonyango lwezingcolisi zetsimbi.

3. Yongeza i-sodium sulfide ekupheleni kwetanki yokudibanisa. Ngaphambi kokunyangwa kwe-coagulation, i-sodium sulfide yongezwa ukuze iqhube i-ion zetsimbi. Ngenxa yokuba uninzi lwee-ion zetsimbi ziye zahlaziywa, unyango olulandelayo lwe-coagulation lunokuphinda luphathe ii-ion zetsimbi ezishiyekileyo, ukuze umgangatho wamanzi uhlanjululwe kunye nomgangatho.
