通过对比活性无烟煤和原煤破碎炭的性能以及动态运行效果表明,原煤破碎炭比活性无烟煤的碘吸附值和亚甲基蓝吸附值略高,其微孔结构更多,但活性无烟煤表征中大孔指标的焦糖脱色率明显比原煤破碎炭高,中孔孔容积高于原煤破碎炭。原煤破碎炭有2.08%的漂浮率而活性无烟煤没有,且原煤破碎炭的填装密度为498g/L,比活性无烟煤的311g/L高出37.5%,活性无烟煤有显著的成本优势。原煤破碎炭对三种有机物指标的吸附性能均优于活性无烟煤,原煤破碎炭对CODMn的吸附容量明显大于活性无烟煤且吸附更快速。两种滤料对进水中的UV254、CODMn、TOC、浊度及消毒副产物均有较好的去除效果,且活性无烟煤效果更佳,运行一段时间后两者的差别有增大的趋势。
By comparing the performance of active anthracite and raw coal broken carbon and the dynamic operating results show that the original coal broken carbon adsorption activity and methylene blue adsorption value of methylene blue adsorption value slightly higher methylene blue microporous structure more active anthracite coal macropore index coke Sugar decolorization rate significantly higher than the original broken coal carbon, pore volume than the original coal broken carbon. Raw coal crushed charcoal has a floating rate of 2.08% and active anthracite is not, and the packing density of broken coal is 498g / L, 37.5% higher than 311g / L of active anthracite, active anthracite has significant cost advantage. Raw coal crushing charcoal adsorbed on three kinds of organic matter indexes are better than active anthracite coal, carbon coal crushed carbon adsorption capacity of CODMn was significantly greater than the active anthracite and adsorption faster. The two kinds of filter media have better removal effects on UV254, CODMn, TOC, turbidity and disinfection by-products in influent, and the effect of active anthracite is better. After running for a period of time, the difference between the two has an increasing trend.
