电渗透脱水是新兴的污泥脱水技术,具有脱水效果好、成本低和无需加入絮凝剂等优点而具有较大的发展前景。通过两轮正交实验,以污泥含水率和脱水能耗为评价体系,研究机械压力、电渗透时间、电压梯度和污泥厚度的最佳操作参数组合;在第一轮正交实验后缩小参数范围后,开展第二轮正交实验,最终确定参数范围。实验结果表明,电渗透脱水的最优化操作参数组合为:机械压力为14.6~15.0 kPa、电渗透时间为58.7~70.0 min、电压梯度为15.1~16.1 V/cm、污泥厚度为0.50 cm。脱水后污泥含水率为55.00%~58.00%,脱水能耗为0.110~0.120 kW·h /kg。在两轮正交实验确定的操作参数下,污泥脱水后含水率达到现行国家标准,而脱水能耗仅为热干化技术的9%~19%。
As a new technology of sludge dehydration, electro-osmotic dehydration has the advantages of good dehydration effect, low cost and without flocculant. Through two rounds of orthogonal experiments and by using moisture content of sludge and dewatering energy consumption as evaluation system, this study investigated the combination of optimal operating parameters of mechanical pressure, electroosmosis time, voltage gradient and sludge thickness. After shrinking range of parameters by the first orthogonal experiment, the second orthogonal experiment was carried out. Finally, the optimal operation parameters were determined as follows: mechanical pressure was between 14.6 and 15.0 kPa, and electroosmosis time was between 58.7 and 70 min, and voltage gradient was between 15.1 and 16.1 V/cm, and sludge thickness was 0.50 cm. After dewatering, the moisture content of sludge was between 55.00% and 58.00%, and ewatering energy consumption was between 0.110 and 0.120 kW·h/kg. The optimal operation parameters obtained through two rounds of orthogonal experiments, the moisture content of sludge can achieve the standards and energy consumption is only 9% to 19% of thermal drying.
