%X 以鱼糜漂洗废水为处理对象，采用zeta电位仪和扫描电镜，测得不同pH下，絮凝悬浮液的zeta电位值及絮凝沉淀物的表面结构，获得了三氯化铁与鱼糜漂洗废水中蛋白质的絮凝机理。结果表明：pH 3～5之间蛋白质失稳由压缩双电层机理和电中和机理起作用，pH 5～6之间蛋白质的脱稳絮凝主要取决于电中和机理，pH 6～8之间以吸附架桥为主要絮凝机理，且存在网捕卷扫作用，pH 9～10主要是生成Fe（OH）3沉淀的网捕卷扫作用实现了对蛋白质的絮凝。</br>The mechanism of flocculation was investigated by zeta potential of surimi waste-water and scanning electron microscope（SEM） images of flocs at different pH. Results showed that at pH 3-5，the mechanism of charge neutralization and double layer compression mainly lead to protein instability；at pH 5-6，protein was flocculated mainly by the mechanism of charge neutralization；at pH 6-8，the mechanism of flocculating mainly depends on adsorption bridging and sweep flocculation；at pH 9-10，sweep flocculation was the main mechanism of flocculating surimi waste-water with ferric chloride
