东北地区城市污水厂运营状况与稳定运行对策

Performances of municipal wastewater treatment plants in Northeast China and strategies for their stable operations

摘要:

为进一步推进东北地区水污染防治工作,确保松花江及辽河流域水环境安全,促进东北地区经济、社会和环境协调发展,对辽宁、吉林及黑龙江3省32家典型城市污水处理厂的运营现状进行调查.结果显示,污水厂普遍存在着科学运营管理水平不高、污水回用率低、污泥处理处置不当等突出问题.今后,在技术及管理层面上,应改进运营模式、完善排水体制、推进污水的资源化、积极寻求技术创新,从而最终实现城市水资源健康循环,推动东北老工业基地经济的可持续发展.
