活性污泥投加低剂量粉末活性炭降低锦纶废水氨氮的应用研究

REDICING THE NH_3-N IN WASTE WATER FROM NYLON 6 BY ACTIVE SLUDGE CONTAINING LOW DOSE POWDERED ACTIVE CARBON

进行了一段单级低剂量粉末活性炭技术(LD-PACT)处理系统(即碳氧化、硝化和反硝化混合污泥相)生产性应用试验。结果表明,LD-PACT工艺出水CODcr比活性污泥法要低,NH_3-N去除效果明显,同时污泥沉降性能有所改善,证明了用这一系统进行生物脱氧是成功的。本工艺不仅适用于新建工程,也可应用于现有设施的挖潜改造,是值得推广的一种生物脱氧好方法。

The experimental operation of single step low dose powdered active carbon technique(LD-PACT)treatment system is carried on for a period.The result shows the CODcr of treated waste water by LD-PACT technique is lower than the simple active sludge method and has much reduction in NH3-N,the sedimentation property of sludge is also improved.The application of this system for biological deoxidization of waste water is proved to be very successful and suitable to both new and old factories.
