摘要
基于GB/T 23485-2009《城镇污水处理厂污泥处理混合填埋用泥质》对出厂填埋用泥含水率小于60%的规定,本文分析了目前国内污水厂已有的污泥处理技术的关键难点,阐述了以高压污泥压榨为主要工艺路线的污泥深度处理系统的优势,最后结合白马镇污水厂污泥深度处理项目的实例,为城镇污水厂突破污泥处置这一关键难点提供了切实可行的方案。
Based on the new requirement that the sludge landfill water content should be under 60% in the disposal of sludge from municipal wastewater treatment plant （ GB/T 23485 - 2009 ） , this paper analysis of the advantages and disadvantages of the existing sludge treatment technology in the domestic sewage treatment plant, expound the advantages of advanced sludge treat-ment process based on high - pressure sludge squeezing technology. Finally, combined with the example of the sewage treatment project of the Baima town sewage treatment plant, it provided a feasible scheme for the municipal sewage treatment plant to break through the key challenge of sludge disposal.
