新型AMBBR-MBBR-MBR工艺处理紫外线吸附剂厂废水

Application of Innovative AMBBR-MBBR-MBR in an Ultraviolet Absorber Manufacturing Wastewater Treatment Project

根据传统工艺处理紫外线吸附剂厂UV-P废水中高级氧化作为预处理成本高,单一A^(2)O生化工艺出水不稳定,并且出水污染物浓度高等缺点,首先采用零价铁强化水解和预曝气作为预处理,以新型AMBBR-MBBR-MBR工艺进行处理。工程MBBR采用三维多孔泡沫陶瓷填料为生物载体,MBR采用SiO_(2)平板陶瓷膜。长期调试运行效果表明,出水水质优于≤城镇污水处理厂污染物排放标准≥GB 18918-2002表1中一级A标准,即COD<50 mg/L,氨氮<5 mg/L,总氮<15 mg/L,硝基苯<2.0 mg/L,挥发酚<0.5 mg/L,苯胺类<0.5 mg/L等。水处理运行费用为4.9元/m^(3)。

In this project,ZVI-assisting hydrolytic acidification and pre aeration process as pretreatment was applied in term of many disadvantages,such as higher cost caused by advanced oxidation process,unstable effluent with low quality,etc in traditional treatment methods.Thereafter,an innovative combined process-anaerobic moving bed biofilm reactor(AMBBR)-moving bed biofilm reactor(MBBR)-member bio-reactor(MBR)was investigated.TheAMBBR and MBBR adopted a microporous foam ceramics as biological carrier.In addition,an innovative SiO_(2)ceramic flat membrane was employed in MBR.The result during successive operation indicated the combined system was operated steadily and the effluent could meet the discharge standard of pollutants for municipal wastewater treatment plant(GB 18918-2002)Table 1 Class A water quality standard(COD≤50 mg/L,ammonia≤5 mg/L,TN≤15 mg/L,Nitrobenzene≤2 mg/L,Volatile phenol≤0.5 mg/LAniline≤0.5 mg/L).The water treatment cost was only 4.9Yuan/m^(3).
