摘要
通过混凝沉淀烧杯实验研究废纸纤维对FeCl_(3)的助凝效果。实验结果表明,废纸纤维对FeCl_(3)处理低浊水具有较好的助凝作用,在提高浊度处理效果的同时还能提升絮体的沉降速度,且采用先加废纸纤维后加FeCl_(3)的方式处理效果更优,当原水浊度为8.9 NTU,FeCl_(3)投加量为20mg·L^(-1)时,适宜的废纸纤维投加量为10mg·L^(-1),处理后出水浊度为1.14NTU,相比单独使用FeCl_(3)的出水浊度降低56.4%。
The coagulation effect of waste paper fiber on ferric chloride was studied by coagulation sedimentation beaker experiment.Experimental results indicated that the waste paper fiber has a favorable coagulation effect on the treatment of low turbidity water with ferric chloride.It can not only strengthen the turbidity treatment effect,but also improve the sedimentation rate of flocs.The treatment effect was better by adding waste paper fiber first and then adding ferric chloride.When the turbidity of raw water was 8.9 NTU,and the dosage of ferric chloride was 20mg·L^(-1),the appropriate dosage of waste paper fiber was 10mg·L^(-1),and the effluent turbidity was 1.14 NTU,which was 56.4%lower than that of ferric chloride alone.
