【摘要】 采用改装上流式反应器,通过实验室模拟试验,研究了pH、硫化物浓度、气提速率等因素对厌氧酸化污泥吸附制革脱毛废液中硫化物的影响。结果表明:经厌氧酸化后,产酸相可将高pH、含硫化物废水的pH值降低至6以下,达到物化酸化脱硫的要求,同时污泥吸附硫化物量降低2%~8%。酸化反应器中硫化物分布不均匀,上部液相硫化物浓度高达114mgS·L-1。气提作用可使液相中硫化物浓度降低30%~50%,但对污泥吸附硫化物无影响,污泥的饱和硫化物吸附量为26.3mgS·L-1。更多还原

【Abstract】 The factors that influence the sulfide distribution of dehairing wastewater in acidification sludge were studied in modified up-flow reactor, for example, pH, the sulfide concentration and gas stripping rate etc. It shows that when the pH of the influent is below 6, the rate of sulfide adsorption can be decreased by 2%~8%. The content of sulfide can be reduced 30%~50% by gas stripping. But the sulfide adsorption of sludge was not affected. and the max adsorption was 26.3 mg S·L -1.更多还原
