摘要:
按照环保政策要求，新建、扩建制浆造纸企业应集中到产业园区，对造纸企业废水进行集中治理。河南某制浆造纸产业园区主导产业为造纸、纸制品加工、包装印刷及相关配套产业，其污水处理工艺由“调节池+絮凝反应沉淀+气水反冲洗滤池”提升改造为“细格栅+调节池+初沉池+UASB池+厌氧沉淀池+氧化沟+OAO生物池+二沉池+芬顿流化床+三沉池+加炭澄清池（应急）+转筒式精密过滤器”，连续半年的运行结果表明，即使进水水质波动较大，提升改造集成工艺对COD、BOD5、SS、氨氮、总氮、TP和色度的平均去除率分别达到98.8%、98.9%、99.3%、87.8%、64.0%、80%和91.4%，出水COD<40 mg/L、氨氮<2 mg/L、总磷<0.4 mg/L，其他水质指标优于《贾鲁河流域水污染物排放标准》（DB 41/908—2014）的排放限值。该提升改造工程投资为21 806万元，综合运行费用为8.29元/m3，对其他类似制浆造纸产业园区污水处理具有一定的借鉴意义。
Abstract:
According to the requirement of environmental protection policy, the new and expanded pulping and papermaking enterprises should be located in the industrial park, meanwhile the sewage of them should be centrally treated. The leading industries of a pulping and papermaking industrial park in Henan Province are papermaking, paper product processing, packaging printing and related supporting industries. The sewage treatment process has been upgraded from “regulating tank, flocculation reaction sedimentation, air-water backwashing filter” to “fine grid, regulating tank, primary sedimentation tank, UASB tank, anaerobic sedimentation tank, oxidation ditch, OAO biological tank, secondary sedimentation tank, Fenton fluidized bed, triple sedimentation tank, charcoal clarifier (emergency), and rotary cylinder type precision filter”. The continuous operation results of six months indicate that even if the influent quality fluctuated greatly, the average removal rates of COD, BOD5, SS, NH3-N, TN, TP and chroma by the upgraded treatment process reach 98.8%, 98.9%, 99.3%, 87.8%, 64.0%, 80% and 91.4%, respectively. The effluent COD, NH3-N, and TP are less than 40 mg/L, 2 mg/L, and 0.4 mg/L, respectively. The other water quality indicators are better than the discharge limits of the Discharge Standard for Water Pollutants in Jialu River Basin (DB 41/908-2014). The upgrading investment of the project is 218.06 million yuan, and the comprehensive operating cost is 8.29 yuan/m3, which has certain reference significance for the wastewater treatment in pulping and papermaking industrial park.
