城市脱水污泥常见的处置方式是焚烧、燃烧发电、堆肥后土地化利用和填埋等。无论采用哪种无害化、资源化处置方法,输送环节都是必不可少的。城市污泥管道输送技术是以管道输送设备为核心,融合城市污泥的预处理和处置工艺的集成化系统。通过对城市污泥的流变特性和输送特性实验测试,其流变方程符合幂定律关系式;通过环管实验拟合出了污泥在管道中的阻力损失与输送距离和输送流量之间的关系,经验证,其理论计算和实际测定基本相符,证明管道输送方式能够成功地应用于城市污泥的远距离输送,为城市污泥管道输送系统的优化设计提供了理论依据。 相似文献

A system to monitor and to control contamination in the soil, as well as in the aquifer is presented. Specifically, the system is suitable to monitor continuously, remotely, and in real-time the soil surrounding underground storage tank (UST) systems, such as in petrol service stations. The system has also functions for remediation, due to the possibility to be configured as a soil venting system. A prototype has been running for more than three years in a petrol service station in Genova, Italy. Results show that, in daily work, frequent small-medium leakages may occur, which may be related to several events, the most frequent of which is the delivery of petrol products to the USTs. In these cases, the system can diagnose the leakage and start remediation by a specific soil venting process. Some considerations on the cost/benefit evaluation of this technology and on the utility to insert it as an important step to assure zero emissions to the soil in connection with petrol product storage and manufacturing are discussed. 相似文献
