摘　　要：当前国家不断加大生态环境的保护力度,污水排放标准日趋严格,落后污水处理工艺亟需提标改造。文章旨在对淄博市某市政污水处理厂污水处理工艺问题进行分析,提出提标改造思路,开展工艺设计及工程建设,进一步提升出水水质。经分析表明,该污水处理厂工艺存在出水水质超标风险大、消毒效果差、污泥含水率高等问题。采用“芬顿氧化反应+粉末活性炭吸附+磁混凝沉淀+V型滤池处理工艺”对原工艺进行提标改造。工程建成并投入运行一年的数据分析表明,相比原工艺,提标改造后的出水水质COD、SS、总磷、总氮、氨氮、色度等指标降低14.7%以上,出水水质达到地表水“准IV类”标准。该污水处理厂的工艺提标改造取得显著效益,可为类似污水处理工艺的提标改造提供参考和借鉴。At present,the state continues to strengthen the protection of ecological environment,so that the sewage discharge standards are becoming increasingly strict,and the backward sewage treatment technology needs to be upgraded.This paper aims to analyze the process of sewage treatment process of a municipal sewage treatment plant in Zibo,puts forward the idea of upgrading the standard for carrying out process design and engineering construction,and further improving the effluent quality.The analysis shows that the wastewater treatment plant has some problems such as high risk of exceeding the effluent quality,poor disinfection effect and high sludge moisture content.The original process was upgraded by adopting the new technology of"Fenton oxidation reaction+powder activated carbon adsorption+magnetic coagulation precipitation+V-type filter treatment process".The data analysis for one year after the project was completed and put into operation shows that,compared with the original process,the effluent quality COD,SS,total phosphorus,total nitrogen,ammonia nitrogen,chroma and other indexes of the upgraded effluent quality are reduced by more than 14.7%,and the effluent quality reaches the"quasi-IV"standard of surface water.The process upgrading of the wastewater treatment plant has achieved remarkable benefits,and can provide reference for similar wastewater treatment process upgrading.
