摘要
随着社会经济的快速发展,全球性的淡水资源短缺和污染已经成为人类面临的重大问题,城市工业用水紧张问题日趋明显,为解决这一问题,污水回用技术应运而生。临泽县城区污水处理厂于2017年率先实施了扩容提标工程,对原CASS处理工艺进行了改良,将污水处理能力由原来的8000m^(3)/日提升为16000m^(3)/日,经深度处理后尾水由原来的一级B标准提升为一级A标准(《城镇污水处理厂污染物排放标准(GB18918-2002)》),从而实现污水再生利用和节水减排目标。
With the rapid development of society and economy,global shortage and pollution of fresh water resources have become a major problem facing mankind.The problem of urban industrial water shortage is becoming more obvious.To solve this problem,wastewater reuse technology has emerged.Linze County Urban Sewage Treatment Plant firstly implemented the expansion and upgrading standard project in 2017,and modified the original CASS treatment process,and the sewage treatment capacity was increased from the original 8000 m^(3)/d to 16000 m^(3)/d.After advanced treatment,the discharged water was improved from original level B standard to level A standard(“Urban Sewage Treatment Plant Pollutant Discharge Standard(GB18918-2002)”),so as to achieve the goals of sewage recycling and water saving and emission reduction.
