为了提高对造纸废水的处理效果，采用磁性Fe3O4/壳聚糖复合微球作为絮凝剂对其进行处理。将水解法制备的Fe3O4微粒分散于壳聚糖溶液中，制备成磁性Fe3O4/壳聚糖复合微球，考察了其投加量、pH、搅拌速度及沉降时间对造纸废水COD去除率的影响。结果表明，在pH为8，搅拌速度为120 r/min，复合微球投加量为6 mg/L，沉降时间为8 h的条件下，当进水COD为2549.41 mg/L时， COD去除率可达到83.38%。
為瞭提高對造紙廢水的處理效果，採用磁性Fe3O4/殼聚糖複閤微毬作為絮凝劑對其進行處理。將水解法製備的Fe3O4微粒分散于殼聚糖溶液中，製備成磁性Fe3O4/殼聚糖複閤微毬，攷察瞭其投加量、pH、攪拌速度及沉降時間對造紙廢水COD去除率的影響。結果錶明，在pH為8，攪拌速度為120 r/min，複閤微毬投加量為6 mg/L，沉降時間為8 h的條件下，噹進水COD為2549.41 mg/L時， COD去除率可達到83.38%。
위료제고대조지폐수적처리효과，채용자성Fe3O4/각취당복합미구작위서응제대기진행처리。장수해법제비적Fe3O4미립분산우각취당용액중，제비성자성Fe3O4/각취당복합미구，고찰료기투가량、pH、교반속도급침강시간대조지폐수COD거제솔적영향。결과표명，재pH위8，교반속도위120 r/min，복합미구투가량위6 mg/L，침강시간위8 h적조건하，당진수COD위2549.41 mg/L시， COD거제솔가체도83.38%。
In order to improve the treatment effect of paper-making wastewater,magnetic Fe3O4/chitosan composite microspheres have been used as flocculant. After the Fe3O4 particles,which were prepared by hydrolysis method, have been dispersed in chitosan solution,magnetic Fe3O4/chitosan composite microspheres can be prepared. The ef-fects of the dosage of magnetic Fe3O4/chitosan composite microspheres,pH,stirring speed and sedimentation time on COD removing rate of paper-making wastewater are investigated. The results show that the COD removing rate can reach 83.38%,under the following conditions:pH is 8,stirring speed 120 r/min,dosage of composite microspheres 6 mg/L,sedimentation time 8 h,and the influent COD of paper-making wastewater 2 549.41 mg/L.
