| Abstract:Pulping and papering wastewater was treated by using IC anaerobic reactor-modified oxidation ditch-shallow air-floatation system, the main construction and commissioning method of the whole system were introduced and analyzed.When the influent CODCr was 4000 mg/L, BOD5 1350 mg/L, SS 2000 mg/L, the effluent CODCr≤60 mg/L, BOD5≤20 mg/L, SS≤30 mg/L, which are meet the emission limits of “the paper industry water pollution discharge standard”(GB3544—2008). |
