Sludge management has become a key issue in wastewater treatment, representing some 20-60% of the operational costs of conventional wastewater treatment plants. The high water content of the sludge results in large daily flow rates to be handled and treated. Thus, the search for methods to improve sludge volume reduction continues to be of major interest. The technology known as sludge treatment wetlands has been used for sludge dewatering since the late 1980s. Major advantages include its low energy requirements, reduced operating and maintenance costs, and a reasonable integration in the environment. However, the number of plants in operation is still low in comparison with conventional technologies. This study represents a review of the state of the art of sludge treatment wetlands. The main characteristics and operational aspects of the technology are described, including a summary of the main results reported in the literature. Finally, the efficiency of sludge treatment wetlands versus conventional treatments is compared.
污泥管理已成为污水处理的关键问题，占传统污水处理厂运营成本的 20-60%。污泥的高含水量导致需要处理和处理的日流量很大。因此，寻求改善污泥体积减少的方法仍然是主要关注点。自 20 世纪 80 年代末以来，被称为污泥处理湿地的技术已用于污泥脱水。主要优点包括其低能源需求、降低运营和维护成本以及在环境中的合理整合。然而，与传统技术相比，运行中的工厂数量仍然较少。本研究代表了对污泥处理湿地技术现状的回顾。描述了该技术的主要特点和操作方面，包括文献中报告的主要结果的摘要。最后，比较了污泥处理湿地与传统处理方法的效率。
