摘    要:对腈纶废水进行Fenton氧化预处理后,运用序批式膜生物反应器进行处理。腈纶废水进水COD平均为1259mg/L;NH4 -N质量浓度平均为57.67 mg/L,经过本工艺处理后,最终出水COD平均仅为76.88 mg/L,其去除率平均达93.89%;出水NH4 -N质量浓度平均为2.57 mg/L,其平均去除率95.54%;出水SS、氰化物、硫氰化物、硫化物等有毒有害物质均低于国家排放标准。再用高浓度腈纶聚合废水对本套工艺进行冲击试验,发现对难降解的腈纶聚合废水也具有很好的处理效果,出水的COD与NH4 -N质量浓度平均为160.66 mg/L和3.16 mg/L,去除率平均达91.86%与92.03%。

关 键 词:腈纶废水  Fenton氧化预处理  序批式膜生物反应器  Fenton与序批式膜生物反应器组合工艺

Abstract:Fenton oxidization pretreatment coupled with sequencing batch membrane bioreactor(SBMBR) was used to treat acrylic fiber wastewater.The result showed: that this system worked efficiently and was strongly impact-resistant.The disposed wastewater could be used as regenerator water,This would reduce environment pollution and save production cost.By using the pretreatment process and SBMBR,COD decreased from 1259mg/L to 76.88mg/L,a reduction of 93.89%;The removal efficiency of NH4 -N was 95.54%.NH4 -N in effluent of SBMBR was 2.57mg/L.The concentrations of SS,CN-,SCN-and S-in effluent of SBMBR were lower than the national standards.Impact experiment for the combined technology was perfomed by using high concentration acrylic fiber wastewater and the system worked efficiently to treat refractory acrylic fiber wastewater.COD,NH4 -N in effluent of SBMBR was160.66 mg/L and 3.16mg/L,with removal rates of 91.86% and 92.03% respectively.
Keywords:acrylic fiber wastewater  Fenton oxidization pretreatment  SBMBR  Fenton oxidization and SBMBR combined technology
