| 摘 要： | 利用活性炭纤维吸波能力强,重复利用的性能,以其为催化剂,联合微波辐射对剩余污泥进行催化氧化预处理.结果表明,当微波功率700W,辐照时间60s,活性炭纤维投加量0.32 g/g SS,污泥分解率可达30.9％,与单独微波辐照相比,污泥分解率增大一倍.由于微生物胞外聚合物(EPS)被分解、胞内物质释放到液相中,使污泥上清...

| Abstract: | Excess sludge was treated by microwave assisted catalytic oxidation using activated carbon fiber as catalysts which has strong microwave-absorbing and recycle ability.Results indicated that microwave irradiation combined with activated carbon fiber increased the lysis of excess sludge.In the optimal operation of 700 W microwave irradiation power,microwave irradiation time of 60 s and activated carbon fiber dosage of 0.32 g/g SS,the sludge dissolving rate increased to 30.9%,which was doubled compared with th... |
