摘要
污泥是污水处理过程中的必然产物,伴随着污泥产生量越来越大,污泥对人类生存环境和经济发展的影响日益突出。如何对污泥进行合理有效的处理和处置,降低其对环境的影响,实现资源化利用,是污泥处置的一个重要课题。为满足《城镇污水处理厂污泥处置混合填埋泥质》(CJ/249-2007)中对填埋污泥含水率的基本要求,东阳市横店污水处理厂采用隔膜式板框压滤机作为核心污泥脱水设备,采用新型生物絮凝剂作为调理药剂,可将出泥含水率控制在60%以下。本文重点介绍采用恒邦生物多糖聚合物为污泥高效脱水剂的污泥调质技术,并与两种传统调质技术进行比较。
Sludge is the inevitable result of the sewage treatment process, with the development of sludge quantity, human survival environment and the impact of economic development is increasingly prominent. Sludge treatment and disposal, how to reasonable and effective to reduce impact on the environment, recycling is a important subject. In order to satisfy the sludge in the process of urban mixed sewage treatment plant sludge disposal landfill the basic requirement of moisture content（CJ / 249-249）, Hengdian Dongyang sewage treatment plant using the diaphragm plate and frame filter press, which is the core of the depth of the sludge dewatering equipment, using the new biological flocculating agent as regulators, sludge moisture content control under 60 %. This article focuses on the use of biological polysaccharide polymer efficient sludge dewatering of sludge treatment technology,and comparing with two traditional processing technology.
