焦点提醒：SediMa混凝手艺在高效沉淀池革新中的项目利用 霍槐槐 （青岛洛克环保科技无限公司，青岛 266071） SediMag®磁混凝手艺在高效沉淀池革新中的项目利用 霍槐槐 （青岛洛克环保科技无限公司，青岛266071） 摘要聊城市某污水处置厂设想范围3.5×104m3/d，出水履行一级A尺度。为进一步消减污染物排放量，该污水处置厂进行提标革新，履行准地表水IV类尺度，此中SS限值为5mg/L,TP限值为0.3mg/L。本文引见了磁混凝沉淀池提标革新的首要设想参数，论述了针对高效沉淀池的池体和装备革新办法。原深度处置段为“2组高效沉淀池+纤����APP维转盘滤池”组合工艺，提标完成后由1组磁混凝沉淀池承当3.5×104m3/d范围全数深度处置功能，不变知足新的出水要求。 要害词混凝凝沉淀池；高效沉淀池革新；污水厂提标革新；地表水准IV类； Application of Upgrading High-efficiency Sedimentation Process to SediMag®Magnetic Coagulation & Sedimentation Process Huo, Huai huai （Qingdao Low-carbon Environmental Technology Co.,Ltd, Qingdao 266071) AbstractA 35,000 m3/d wastewater treatment plant in Liaocheng City, which effluent Level 1 Standard is implemented. In order to further reducethe emission of pollutants, the wastewater treatment plant has been upgraded andreconstructed with ClassIV surface water standard, which the SS limit is 5 mg / L and the TP limit is 0.3 mg / L. This paper introduces the main design parameters of the magnetic coagulation sedimentationtank, and describestheimprovementmeasures for thehigh-efficiencysedimentation tank body and equipment modification.The original deep treatment section is combined by 2 sets of high-efficiency sedimentation tank and fiber rotary disc filter. After the completion of the standardupgradation, the 1 group of magnetic coagulation sedimentation tanks will undertake all the deep-processing functions of 35,000m3/ d, stably meeting the new watereffluentrequirements.
