摘　　要：考查了一种两性高分子絮凝剂P(FA/NVP/DMC)对钻井废水的絮凝性能。试验显示,在pH=7、投加量为186.94mg/L条件下,CODCr去除率达到90.2%,浊度去除率达到98.9%;对钻井废水絮凝处理后的絮体进行电镜扫描,运用非线性数学分形理论计算絮体空隙分维数,结果表明,理论计算与试验结果一致。The effect of an amphoteric macromolecule flocculant, P （FA/NVP/DMC）, was investigated in processing drilling wastewater. The results showed that when the pH was 7 and the floeeulent dosage was 186.94 mg/L,removal rate of CODc, and tur- bidity were 90. 2% and 98.9% , respectively. At the same time, the Df values of fraetal dimension were computed on analyzing drill- ing wastewater flocs SEM and utilizing Non-Linear fractional theory, the theorical computation result is eoordinated with the test result.
