CPB与HDTMA改性沸石处理DDNP废水试验研究

Experimental Investigation on CPB and HDTMA Modified Zeolite for the Treatment of DDNP Wastewater

研究了采用溴代十六烷基吡啶(CPB)与十六烷基三甲基溴化铵(HDTMA)改性的天然沸石处理二硝基重氮酚(DDNP)废水的性能及影响因素。以CODcr和色度去除率作为研究指标,实验结果表明:CPB改性沸石的性能优于HDTMA改性沸石。

That the natural zeolite modified by CPB and HDTMA separately is used to treat DDNP wastewater and its influencing factors are studied. The removal rate of CODCr and the chroma in wastewater are the norm of the investigations. The experimental result shows： the performance of CPB modified zeolite is more superior than HDTMA modified zeolite.
