| Abstract: | Taking chemical integrated wastewater as the research object,an experiment of Fenton-flocculation process treating integrated wastewater from a chemical park was carried out.The influences of Fenton reaction time,initial pH value,dosage of H2O2 and Fe2+,initial pH value of the flocculation,flocculant dosage and some other factors on the treatment effect were investigated.It could be seen that,when the Fenton reaction time was 60 min,the initial pH value was 3.5,the dosage of H2O2 and FeSO4·7H2O were 6.5 mmol/L and 600 mg/L respectively,the initial pH value of the flocculation was 6.5,the PAM dosage was 0.9 mg/L,the removal rates of CODCr,turbidity and chroma in the raw water reached 78.86%、96.64% and 98.65% respectively,the m(BOD5)/m(CODCr) increased from 0.18 to above 0.5,the biodegradability of the wastewater was significantly improved. |
| Keywords: | Fenton flocculation chemical integrated wastewater pretreatment biodegradability |
