Indlela Yokubala Isilinganiso se-potassium Permanganate ye-Iron, Manganese kanye ne-Hydrogen sulfide Removal

I-Potassium permanganate (KMnO₄) ivamise ukusetshenziswa ekwelapheni kwamanzi ukuze kufakwe insimbi enensimbi (Fe²⁺), i-manganese encibilikisiwe (Mn²⁺), ne-hydrogen sulfide (H₂S) ngaphambi kokuhlunga.

Kodwa omunye wemibuzo ebaluleke kakhulu kwabasebenzisa amanzi kanye nabathengi bamakhemikhali uthi:

Malini Ingabe i-potassium permanganate kufanele ifakwe?

Impendulo incike ekugxilweni kokungcola, ikhemistri yamanzi aluhlaza, i-pH, izinto eziphilayo, isikhathi sokuxhumana, kanye nesistimu yokuhlunga. Indlela engokoqobo yile:

Ukuhlaziywa kwamanzi → Bala Isidingo Sasekuqaleni → Ukuhlolwa Kwejeke → Hlola Okusele → Ukuhlunga

Isiqondiso se-US EPA sikhomba i-permanganate njengendlela yokwelapha ye-iron ne-manganese oxidation futhi siphawula ukuthi imithamo yangempela incike kakhulu kwikhwalithi yamanzi kanye nendawo yokusetshenziswa.

I-Potassium Permanganate Dosage: Inkomba esheshayo

Ekubalweni kokuqala, izilinganiso ezilandelayo ziwusizo:

Imibhalo yobuchwepheshe ye-EPA inika izidingo zethiyori ezingaba ngu- 0.94 mg/L KMnO₄ ku-1 mg/L yensimbi kanye no -1.92 mg/L KMnO₄ ku-1 mg/L manganese.

Ngokulawulwa kwe-sulfide yamanzi angcolile, isiqondiso se-EPA sibika izilinganiso zesisindo ze-KMnO₄-to-H₂S cishe ezingu-6:1 ukuya ku-7:1 njengobubanzi obujwayelekile bokusebenza.

Lawa manani kufanele athathwe njengezindawo zokuqala kunemithamo yokugcina yokusebenza.

1. Ubalwa Kanjani Umthamo we-KMnO₄ Wokukhipha Insimbi

Insimbi eyinsimbi encibilikisiwe ingafakwa i-oxid ibe yizingxube ze-ferric ezingancibiliki ezisuswa kamuva nge-sedimentation noma ukuhlunga.

Ubudlelwano bethiyori bucishe bube:

1 mg/L Fe²⁺ × 0.94 = 0.94 mg/L KMnO₄

Isibonelo

Uma amanzi aluhlaza equkethe:

I-ayoni = 2.0 mg/L

Bese:

2.0 × 0.94 = 1.88 mg/L KMnO₄

Ngakho-ke, imfuneko yokuqala yethiyori ye-potassium permanganate icishe ibe:

1.88 mg/L

Kodwa-ke, izinto eziphilayo zemvelo nezinye izinto ezinciphisayo zingasebenzisa i-permanganate, ngakho-ke umthamo wangempela wesitshalo kufanele uqinisekiswe ngokuhlolwa.

2. Ubalwa Kanjani Umthamo we-KMnO₄ Wokususwa KweManganese

I-Manganese ngokuvamile idinga i-potassium permanganate eningi kune-iron.

Ubudlelwano bethiyori bucishe bube:

1 mg/L Mn²⁺ × 1.92 = 1.92 mg/L KMnO₄

Isibonelo

Uma ukugxila kwe-manganese kungu:

0.5 mg/L Mn²⁺

Bese:

0.5 × 1.92 = 0.96 mg/L KMnO₄

Isidingo esibaliwe sokuqala sithi:

0.96 mg/L KMnO₄

Isidingo esilinganiselwe se-KMnO₄:

0.5 × 6 = 3.0 mg/L

ku

0.5 × 7 = 3.5 mg/L

Ngakho ububanzi bokuhlola bokuqala bungaba cishe:

3.0–3.5 mg/L KMnO₄

Ngenxa yokuthi amakhemikhali e-sulfide ashintsha nge-pH nezimo zokwelashwa, ukuhlolwa kwebhentshi kubaluleke kakhulu ngaphambi kokusungula izinga lokugcina lokuphakela.

4. Ibalwa kanjani i-KMnO₄ Uma Kukhona Ukungcola Okuningana

Amanzi angaphansi komhlaba angempela angase abe nensimbi, i-manganese, ne-hydrogen sulfide ngesikhathi esifanayo.

Isilinganiso sokuqala esiwusizo yilesi:

Isilinganiso se-KMnO₄ Demand = Isidingo Sensimbi + Isidingo SeManganese + Isidingo se-H₂S

Ngokwesibonelo, ake sithi ukuhlaziywa kwamanzi kubonisa:

• I-ayoni: 1.5 mg/L

• I-Manganese: 0.20 mg/L

• I-H₂S: 0.10 mg/L

Isidingo Sensimbi

1.5 × 0.94 = 1.41 mg/L

Isidingo seManganese

0.20 × 1.92 = 0.384 mg/L

Isidingo se-H₂S

0.10 × 6–7 = 0.60–0.70 mg/L

Isidingo Sokuqala Esilinganiselwe se-KMnO₄

1.41 + 0.384 + 0.60–0.70

= cishe 2.39–2.49 mg/L KMnO₄

Lokhu kunikeza u-opharetha ububanzi bokuhlola bokuqala , hhayi indawo yokubeka umthamo wokugcina ozenzakalelayo.

5. Kungani Imithamo Yethiyori Ingeyona Isilinganiso Sokugcina
