摘 要

利用城镇污水处理厂污泥和清淤海泥两种废弃泥添加辅料制备陶基填料。控制烧制条件，通过对污泥、海泥和添加剂进行不同的配比，根据基础性实验初步估计：烧制出陶基填料的配比条件为海泥成分30%-50%，污泥成分40%-60%，添加剂为10%；且随着污泥质量分数的增大（海泥质量分数的减小），抗压强度逐渐减小，而吸水率则相反。通过选用三种不同配比和三种不同粒径的陶基填料对污水中总磷、氨氮进行吸附等温实验，分析结果表明：陶基填料对总磷吸附实验使用Freundlich方程拟合较好，5组数据比较，粒径越小，比表面积越大，吸附性能越好；污泥配比越多，吸附性能越好，主要原因为污泥中Fe³ 、Ca² 和Mg² 的含量多于海泥，易于磷酸盐结合形成表面沉淀使其固定下来被吸附。陶基填料对氨氮吸附实验效果较差，等温模拟相关系数较低，不符合等温吸附方程。环境安全性测试表明，陶基填料中氯离子含量的测试结果为0.00%，可溶性盐含量极低，表明陶基填料不存在氯离子重金属二次污染问题。

The use of urban sewage treatment plant sludge and dredging mud mud add two kinds of waste materials for preparing ceramic-based filler. Controlling the firing conditions, through making the sludge, mud and additives a different ratio, according to preliminary estimates of the basic experiment: the ratio of firing pottery conditions for mud-based filler content of 30% -50%, the sludge component 40% -60%, 10% of the additive; and with the increasing mass fraction of the sludge (mud mass fraction decreases), the compressive strength decreases, and the water absorption on the contrary. By choosing three different ratios and three different particle size of filler in sewage Pataki total phosphorus, ammonia nitrogen adsorption isotherm experiments, the results show that: Tao based filler for total phosphorus adsorption experiments using the Freundlich equation fits better, 5 group data compare:the smaller the particle size, the larger specific surface area is, the better adsorption performance is; the more sludge ratio is, the better the adsorption performance is, mainly due to sludge Fe³ , Ca² and Mg² content of more than mud, easy combine to phosphate form salt deposited on the surface down to secure it to be adsorbed. Pataki filler for poor ammonia adsorption experiment results, isothermal simulation correlation coefficient is low, does not meet the isotherm equation. Environmental safety tests have shown that the test results Pataki filler chloride ion content of 0.00%, soluble salt content is extremely low, indicating no presence of chlorine-based filler Tao heavy metal ion secondary pollution.
