摘要

为解决现有除磷吸附剂粒径小造成的材料易流失和系统压降过大等问题，以实现吸附除磷工艺在实际工程中的应用，以聚氨酯填料为载体，水

溶性聚氨酯为介质，将水化硅酸钙负载到聚氨酯填料上制成负载型除磷填料。研究了制备条件对除磷填料除磷效果的影响，采用扫描电子显微镜（SEM）和傅里叶变换红外光谱仪（FTIR）观察分析了负载前后水化硅酸钙微观结构及化学基团的变化；利用除磷填料作为除磷吸附床的滤料，研究了运行条件对吸附床除磷效果的影响。在此基础上，利用响应曲面法研究了除磷吸附床磷酸盐去除率和各变量之间的关系，并对工艺参数进行了优化。结果表明，水性聚氨酯溶液的浓度和用量分别为100 g/L和50 ml，水化硅酸钙的质量为12 g的条件下所制备的除磷填料除磷效果最好；SEM和FTIR分析结果显示，水化硅酸钙负载前后其孔隙结构和化学基团没有明显的变化；预测模型的方差分析结果表明，HRT(

Abstract

To solve the problems of easy loss of materials and excessive system pressure drop caused by the small particle size of the existing phosphorus removal adsorbent

the application of the adsorption phosphorus removal process in practical engineering is realized. In this study

polyurethane filler was used as carrier

water-soluble polyurethane was used as medium

and hydrated calcium silicate was loaded onto polyurethane filler to make supported phosphorus removal filler. Effect of prepared methods on phosphate removal efficiency of the phosphorus removal filler was studied to obtain the optimum preparation conditions. The change of microstructure and chemical groups of hydrated calcium silicate before and after loading onto polyurethane carriers was revealed by scanning electron microscope (SEM) and Fourier transform infrared spectrometer (FTIR). Effect of operation parameters on phosphate removal efficiency of adsorption bed using phosph

orus removal filler as packing materials was investigated through single factor experiment. Based on the results obtained from the single factor experiment

an ideal experimental design was carried out based on central composite design (CCD) with response surface methodology (RSM). The results showed that

the optimum conditions for the preparation of phosphorus removal filler were 50 ml waterborne polyurethane with concentration of 100 g/L

and the hydrated calcium silicate dosage of 12 g. SEM and FTIR observations showed that the pore structure and the chemical groups of hydrated calcium silicate changed slightly after loading onto the filler. The variance analysis of the predication model indicated that HRT(
