摘要

  • 摘要: 含水率是影响污泥处置效果与成本的重要因素。通过污泥含水率、毛细吸水时间(CST)、污泥比阻(SRF)、污泥上清液中的蛋白质、多糖、DNA含量等指标,研究了类芬顿试剂耦合超声对活性污泥脱水性能的影响。结果表明,类芬顿试剂中H2O2的投加量为90 mg/g,Fe3+的投加量为10 mg/g,超声3 min, 此时污泥的毛细吸水时间为29.8 s,污泥比阻为2.07×1011 s2/g,污泥的含水率降至73.9%。类芬顿试剂耦合超声能有效破坏污泥絮体结构,增加上清液的蛋白质、多糖、DNA含量。
    Abstract: The moisture content of sludge significantly influences its dewaterability and subsequent disposal costs. Ultrasonic and Fenton-like reagents were investigated for sludge dewatering with combined conditioning. Several parameters were used to evaluate the dewatering performance, such as cake moisture, capillary suction time (CST), specific resistance of filtration (SRF), and the protein, polysaccharide, and DNA contents in the supernatant. Based on the experimental results, the operation conditions were optimized with hydrogen peroxide (H2O2) dosage of 90 mg/g, iron (Fe3+) dosage of 10 mg/g, and an ultrasonic time of 3 min. The CST was 29.8 s, the specific resistance of filtration (SRF) was 2.07×1011 s2/g, and the moisture was as low as 73.9%. The Fenton-like reagent with ultrasonic coupling significantly destroyed the floc structure of sludge and increased the amount of protein, polysaccharide, and DNA in the sludge supernatant.
