摘要:将超声波破解与沸石骨架构建两种方式联合起来调理污泥，探究其脱水效果及机理，再将超声、沸石及联合调理后的脱水污泥进行好氧堆肥，分析不同调理方式对堆肥效能的影响。脱水实验结果表明，超声与沸石联合调理具有协同效应，可显著提高污泥脱水性能，且先沸石后超声效果更优。堆肥实验结果表明，3 种脱水污泥均可正常堆肥，通过分析含水率、有机质、TOC、氮、磷、钾、重金属和种子发芽指数（GI）等因素发现，联合调理可加快污泥好氧堆肥腐熟进度，并得到重金属含量最低、GI最高的无毒害产品。可见，该联合工艺具有一定的推广应用价值。
Abstract:This paper combined ultrasonic wave cracked sludge and zeolite as the skeleton constructor to condition sludge, explored the dewatering performance and related mechanism, composted the dewatered sludge aerobically conditioned by three methods (ultrasonic wave, zeolite and ultrasonic wave combined with zeolite), and investigated the effect of different conditioning methods on the aerobic composting efficiency. The dewatering test results showed that the combined condition of ultrasonic wave and zeolite had a synergistic effect, which could significantly improve the sludge dewatering performance, and the first zeolite condition followed by ultrasonic wave showed a better performance. The composting test results showed that the three types of dewatered sludge could be composted normally. The analysis of the moisture content, organic matter, TOC, nitrogen, phosphorus, potassium, heavy metal content and seed germination index (GI) and other factors showed that the combined conditioning method accelerated the maturity of aerobic sludge composting, and thus the non-toxic products with the lowest heavy metal content and the highest GI were obtained. Therefore, the combined process demonstrated certain application prospect.
