对3.5万m3/d竹材制浆废水处理工程工艺进行了优化,当二沉池出水COD为200 mg/L左右时,混凝剂由PAC改为高效混凝剂,投加量为1.5 kg/m3,助凝剂阴离子PAM投加质量浓度为5 mg/L,气浮处理后出水COD为66~89 mg/L,色度则降至10~30倍,排放水感观大大改善,各指标完全满足了《制浆造纸工业水污染物排放标准》(GB 3544—2008)要求.
對3.5萬m3/d竹材製漿廢水處理工程工藝進行瞭優化,噹二沉池齣水COD為200 mg/L左右時,混凝劑由PAC改為高效混凝劑,投加量為1.5 kg/m3,助凝劑陰離子PAM投加質量濃度為5 mg/L,氣浮處理後齣水COD為66~89 mg/L,色度則降至10~30倍,排放水感觀大大改善,各指標完全滿足瞭《製漿造紙工業水汙染物排放標準》(GB 3544—2008)要求.

The running process of the 35 000 m3/d bamboo pulp wastewater treatment engineering has been optimized.When the COD of effluent from the second sedimentation pond is about 200 mg/L,highly efficient coagulant is used instead of coagulant PAC,whose dosage is 1.5 kg/m3.The mass concentration of added dosage of coagulant aid anion PAM is 5 mg/L.After flotation treatment,the effluent COD is 66-89 mg/L,chroma drops to 10-30 times.The discharged water looks much better.All of the indexes meet the requirements specified in the Discharge Standard of Water Polluents from Paper and Pulp Industry(GB 3544—2008).
