摘要

利用正交法设计实验,研究超细滑石粉SFT( 1 250 目)代替PAM作助凝剂对再生纸造纸废水进行混凝处理。研究结果表明, SFT可以替代PAM,且PAC+ SFT方案的最佳组合方式为: pH 6. 5, PAC 300 mg /L, SFT3 mg / L。此时,浊度去除率为97%以上,色度去除率为87. 7%,沉降速度提高35%,处理废水用药品成本降低0. 104 6元/m3

Abstract

Designed by means of orthog onal experiment method, experiments were carried cut to study the possibility of SFT as a substitute for PAM to treat wastewater from reproduced papermaking. The results show that SFT can be used as a substi tute for PAM. The optimum combination of PAC, SFT and pH value is 300mg /L,3 mg /L and 6.5.Thus the rate of turbidity removal is up to 97%,that of color removal being 87. 7% .setting rate improving 35%, coagulant cost deducting 0.104 6$ /m3 .
