采用旋转式脱泡消泡法处理造纸循环用水，浮浆含量降至原来的9.1%，加入消泡剂，泡沫去除率达85%，进一步调节废水pH≈7，加入复合混凝剂PAC（10.0380 g/L）：PFS（9.8912 g/L）：CPAM（1.0000 g/L）=5：2：2（体积比）9 mL/L黑液的条件下，COD去除率达到96.7%，脱色率达到55.7%，基本符合了二次用水的标准，可重新用于造纸制浆，使废水循环利用，实现了造纸废水的资源化。
採用鏇轉式脫泡消泡法處理造紙循環用水，浮漿含量降至原來的9.1%，加入消泡劑，泡沫去除率達85%，進一步調節廢水pH≈7，加入複閤混凝劑PAC（10.0380 g/L）：PFS（9.8912 g/L）：CPAM（1.0000 g/L）=5：2：2（體積比）9 mL/L黑液的條件下，COD去除率達到96.7%，脫色率達到55.7%，基本符閤瞭二次用水的標準，可重新用于造紙製漿，使廢水循環利用，實現瞭造紙廢水的資源化。
채용선전식탈포소포법처리조지순배용수，부장함량강지원래적9.1%，가입소포제，포말거제솔체85%，진일보조절폐수pH≈7，가입복합혼응제PAC（10.0380 g/L）：PFS（9.8912 g/L）：CPAM（1.0000 g/L）=5：2：2（체적비）9 mL/L흑액적조건하，COD거제솔체도96.7%，탈색솔체도55.7%，기본부합료이차용수적표준，가중신용우조지제장，사폐수순배이용，실현료조지폐수적자원화。
The papermaking wastewater was treated by the rotary system deaeration antifoaming law,float-ing pulp content to the original 9. 1%,adding defoamer,bubble removal rate reached 85%,further regu-late wastewater pH ≈7 ,conditions of adding compound coagulant 9 mL/L black liquor [ PAC (10. 038 0 g/L):PFS(9. 891 2 g/L):CPAM(1. 000 0 g/L)]=5 :2 :2( volume ratio),the COD re-moval rate reached 96 . 7%,the decoloration rate reached 55 . 7%,in line with the standards of secondary water. Thus the paper can be re-treated wastewater used for paper pulp and waste water recycling,to achieve the papermaking wastewater resources.
