| Abstract: | Based on the characteristics of the production of wastewater for mobile phone screen plant,the upgrading and reconstruction project of sewage treatment are carried out.According to the wastewater quality,the adidolysis-advanced oxidation pretreatment-membrane bioreactor(MBR) process is used in this study.The results show that,when the CODCr in acidolysis tank decreases from 1 500 mg/L to 600 mg/L,the biochemical activity increase from 0.27 to 0.15.When CODCr in advanced oxidation unit decreases from 560 mg/L to 240 mg/L,UV254 of the wastewater decreases from 0.946 to 0.154.UV254 of the wastewater is reduced by 83.7%.SUVA of the wastewater decreases from 0.00675 to 0.00296 and SUVA of the wastewater is reduced by 56.14% and m(BOD5)/m(CODCr) rises to 0.34.The removal rate of CODCr in MBR can reach 60%.The final effluent discharge can meet GB 8978—1996 "Integrated Wastewater Discharge Standard" Grade Ⅲ. |
