三亚市排水管渠污泥特性及处理工艺

在雨污水管网养护过程中，清掏出的管网沉积污泥含有大量垃圾、泥砂及腐殖物，含水率高且臭味浓度高，传统处理方式已经不能满足环保要求。随着我国经济的发展以及国家对环境保护的需要，如何对管渠污泥进行经济而有效地处理处置和资源化利用是当前必须解决的问题。为有效解决三亚雨污水管网运营维护中清淤污泥的处理及出路问题，对三亚排水管渠污泥进行了采样检测并分析其基本特性，采用预处理+回收利用联合处理，实现污泥的减量化、无害化处理和资源化利用，解决了当地雨污水管道清淤污泥的出路难问题，可在其他类似处理工程中推广运用。

Characteristics and Treatment Process of Sludge in Drain Pipe in Sanya City

During the maintenance process of the rainwater and sewage pipeline network, the sludge deposited from the cleaned pipeline network contains a large amount of garbage, mud, sand and humus with high moisture content and high odor concentration. The traditional treatment methods can no longer meet the environmental requirements. With the development of economy and the need for environmental protection in China, it is currently necessary to solve the issue of how to economically and effectively treat, dispose and utilize the pipeline sludge as resources. In order to effectively solve the problem of sludge treatment and usage in the operation and maintenance of the rainwater and sewage pipeline network in Sanya, the sampling and testing are conducted on the sludge in the drain pipeline in Sanya, and its basic characteristics are analyzed. The combined treatment of pre-treatment and recycling is adopted to achieve sludge reduction, harmless treatment, and resource utilization, which solves the problem of sludge usage difficulty in the local rainwater and sewage pipelines, and can be promoted and applied in other similar treatment projects.
