摘要
对污泥进行调理改性,提升污泥脱水性能是实现污泥妥善处置和资源化利用的重要前置条件。基于絮凝原理的调理技术效果显著,成本可控,是改善污泥脱水性能的最可靠和应用最广泛的技术之一。此外,絮凝联合调理技术能发挥协同作用,功能特性更加完备,是当下污泥脱水的研究热点。介绍了污泥处理处置现状及污泥脱水的技术难点,阐述了不同种类絮凝剂和絮凝联合调理技术的作用机理及应用效果,以期为利用絮凝调理技术强化污泥脱水性能提供理论依据和应用参考。
It is an important prerequisite for proper disposal and resource utilization of sludge to improve its dewaterability with conditioning pretreatment.Conditioning based on flocculation is the most reliable and widely used technology for improving sludge dewaterability due to its significant effects and controllable costs.In addition,the combined flocculants can play a synergistic role and have more diverse functionality,which is a research hotspot of sludge dewatering.The current situation of sludge disposal and treatment,as well as the difficulties in sludge dewatering were introduced.The mechanism and application of various flocculants or their combined usage were elaborated.This paper is expected to provide theoretical basis and application reference for the utilization of flocculationbased technology to enhance sludge dewaterability.
