对于国家经济建设及社会稳定发展而言,水资源既是基础资源,同时也是战略能源,因此,做好城市水资源的综合治理是实现国家可持续发展的必要条件之一。对于城市污水而言,实现污水的无害化处理是水资源重复循环利用的重要方式。目前,国内的城市污水处理技术已较为成熟,但美中不足的是,污水处理厂在实现水资源循环可持续利用的同时,伴随出现了二次能耗,且能耗指标在工业领域属中上地位,耗能主要包括:电能、化学能等,其中电能占到总能耗的65%以上。研究发现,影响污水处理厂综合能耗的因素来源于污水厂所处环境、污水厂工艺技术、污水厂自动化程度及被处理污水的污染程度等。本文在总结国内某污水处理厂的相关自动化控制设备及方案的基础上,具体分析了污水处理厂的节能指标和能效。……
