改良型氧化沟废水治理工程的调试

Commissioning of improved oxidation ditch in an effluent treatment project

介绍了采用供气式低压射流曝气系统的改良型氧化沟用于箱纸板废水处理,并对整个调试运行过程进行了分析。改良型氧化沟采用全好氧曝气,沟中不存在缺氧区和厌氧区,抑制了传统氧化沟中的硝化与反硝化作用,降低了营养盐的投加成本,具有很强的抗冲击能力。运行结果表明,出水水质可达到造纸工业水污染物排放的国家标准。

An introduction is made on the application of an air supply low pressure jet aeration system in an improved oxidation ditch in the treatment of the liner board effluent with a detailed introduction and analysis on the commissioning of the operational process. The operating results show that quality of the outlet water reached the national standard of water pollutant discharge for pulp and paper industry,
