摘　　要：采用CTB工艺处理城市污泥,并同时使用介电法和烘干法测定堆体含水率,对这两种含水率测定方法进行了比较。试验结果表明,采用CTB工艺进行好氧发酵,可以快速将堆体含水率由66%降至50%;使用分段温度标定法能够显著提高介电法的测定精度,且稳定性高于烘干法。Control technology for bio-composting （CTB） technology was applied to dewatered sew- age sludge. Moisture measurements during the sewage sludge composting process using the dielectric method and gravimetric method were compared. The results showed that the moisture content of composting material could be reduced from 66% to 50% by CTB technology. The accuracy of dielectric method could be increased after temperature calibration. The stability of the result was better than that using the gravimetric method.
