磁混凝技术在造纸废水处理厂气浮池改造中的工程应用

Engineering Application of Magnetic Condensation Technology in the Remodel of Air Flotation Tanks in Papermaking Wastewater Treatment Plants

盐城市某造纸废水处理厂处理规模为3.5×10^(4)m^(3)/d,原设计排放标准为《城镇污水处理厂污染物排放标准》(GB18918-2002一级B标准)TN执行《制浆造纸工业水污染物排放标准》(GB3544-2008)表2制浆造纸联合生产企业标准,本次提标及技改项目将原气浮系统改造为粉末活性炭-磁混凝沉淀系统,改造后排放标准达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准TN执行《制浆造纸工业水污染物排放标准》(GB3544-2008)表3制浆造纸联合生产企业标准)。

The treatment scale of a papermaking wastewater treatment plant in Yancheng City is 3.5×10~4 m~3/d, The original design emission standard was 《Pollutant discharge standards for urban sewage treatment plants》(GB18918-2002)Level 1 B standard(TN executes 《Discharge standards for water pollutants in the pulp and paper industry》(GB3544-2008)table 2 pulp and paper joint production enterprise standards), the bid raising and technical transformation project transformed the original air flotation system into a powder activated carbon-magnetic coagulation precipitation system, after the renovation, the emission standards are met 《Pollutant discharge standards for urban sewage treatment plants》(GB18918-2002)Level 1 A standard(TN executes 《Discharge standards for water pollutants in the pulp and paper industry》(GB3544-2008)table 3 pulp and paper joint production enterprise standards).
