| 摘 要： | 以钛铁矿为原料制备聚合钛铁净水剂（I-PTF），并利用扫描电子显微镜和X射线衍射仪分析其微观特性。通过烧杯实验和污泥沉降实验研究I-PTF净水效果和污泥沉降性能，并利用荧光显微镜观察其污泥形貌。结果表明：I-PTF对CODCr的去除效果优于聚合氯化铝（PAC），在投药量为168 mg/L时，I-PTF对于CODCr的去除率比PAC高22%；与PAC相比，I-PTF的污泥体积减量率达到80%以上，其沉降速度也快，11 min左右即可沉降完成；I-PTF形成的絮团更加紧密，边界更加清晰。

| Abstract: | Polyferric titanium water purification agent (I-PTF) was prepared from ilmenite and its microscopic properties were analyzed using scanning electron microscopy and X-ray diffraction. The water purification effect and sludge settling performance of I-PTF were studied through beaker and sludge settling experiment. The morphology of sludge was observed using a fluorescence microscope. Results showed that the removal rate of CODCr by I-PTF was better than polyaluminium chloride (PAC). When the dosage was 168 mg/L, the removal rate of CODCr by I-PTF was 22%,and it was higher than that of PAC. Compared with PAC, the sludge volume reduction rate by I-PTF was more than 80%, and its settling speed was faster. The settling could be completed in approximately 11 minutes. The flocs formed using I-PTF were more compact and the boundary was clearer. |
