摘要
利用惰性电极形成的外加电场对强化生物除磷的效果进行了研究。实验采用两套结构尺寸完全一致的反应器进行对比实验,确定生物除磷过程适宜的工况条件,测定了在各种实验条件下水相及剩余污泥中磷含量的变化情况。在有无外加电场的情况下,对生物除磷的动力学参数进行了比较。实验结果表明:电场的作用促进厌氧放磷,同时也促进好氧吸磷,相应的动力学参数均有明显的提高。
The effects of enhanced biological phosphorus removal with electric field formed by inert electrode were studied. Parallel experiments were carried out by two bio-reactors which had the same structure and size to determine the suitable conditions of phosphorus removal, and the change of phosphorus content both in aqueous phase and surplus sludge was determined under different experimental conditions. The dynamic parameters of biological phosphorus removal were compared under the conditions with or without electric field. The results showed that the electric field could promote releasing phosphorous under anaerobic condition as well as absorbing phosphorous under aerobic condition, and corresponding dynamic parameters increased obviously.
