摘要:
为了探索一种低成本、节能、设备简单、操作方便的处理中浓度酚醛树脂生产废水的工艺，使废水处理后满足可生化处理的要求，采用聚偏氟乙烯（PVDF）管式超滤膜处理化学需氧量(COD)为6 000 mg/L、挥发酚为3 000 mg/L的中等质量浓度酚醛树脂生产废水.探讨了进料流速、跨膜压差、料液温度、浓缩比等因素对膜性能的影响.结果表明：料液温度升高，挥发酚和COD的截留率都下降；跨膜压差增大可提高对挥发酚和COD的截留率.超滤酚醛树脂废水的最佳工艺条件：跨膜压差40 kPa，流速1.4 m/s，温度25 ℃的条件下，挥发酚的截留率可达到43%，COD的截留率可达到48%，酚醛树脂生产废水的可生化性得到明显改善.对膜的清洗进行了实验，用自制的质量分数0.5%双氧水+0.3%氢氧化钠水溶液对膜进行清洗，能使膜通量部分恢复.
Abstract:
To explore a cost\|saving, simple equipment, easy operation process of treating phenolic resin wastewater with middle concentration for meeting the requirements of biological treatment, the polyvinylidene fluoride (PVDF) tubular ultrafiltration membrane was employed to treat the phenolic resin wastewater with chemical oxygen demand (COD) of 6 000 mg/L, and volatile phenol of 3 000 mg/L. Influences of flow velocity, transmembrane pressure, feed temperature, and concentration ratio on membrane performance were discussed. The results show that the COD and phenol rejection rates decrease with temperature increasing, and increase with the pressure increasing. The optimal operation conditions are found that the COD and phenol rejection rates reach 48% and 43% respectively under the transmembrane pressure of 40 kPa, flow velocity of 1.4 m/s and temperature of 25 ℃. Consequently, the biodegradability of phenolic resin production wastewater is significantly improved. The cleaning of the fouled membranes is examined by using of Sodium hydroxide of 0.3% and hydrogen peroxide of 0.5%,which recovers membrane flux partly.
