摘要
福建南纸在原有的3万t/d的废水处理设施上增加了超效浅层离子气浮法深度处理设施,该深度处理采用气浮絮凝法,利用浅层气浮处理并加入化学絮凝剂,使二沉池出水的CODCr从原来的300 mg/L以上降至90 mg/L以下,达到了GB3544—2008制浆造纸工业水污染物排放标准的要求。
In order to meet the requirement of ＂pulp and paper industry water pollutant discharge regulation ＂ GB3544-2008, Nanping Pa-per constructed advanced treatment device based on the original 30,000 t/d effluent treatment facilities. The CODcr of recovery clarification effluent reduced from more than 300 mg/L to less than 90 mg/L after flocculation and high-efficient shallow air flotation; treatment.
