摘要
研究了褐煤作为吸附剂,处理煤化工气化废水。通过投加量、温度、时间等因素的试验,通过哈希DR3900分光光度计,研究褐煤吸附煤化工气化废水的总氮效果。当褐煤的用量达到400g/L时,其对总氮的去除率可达到近60%。褐煤作为吸附剂去除废水总氮的方法可作为煤化工废水处理的预处理。
In this study, lignite was used as an adsorbent to treat coal chemical gasification wastewater.Through the experiment of factors such as dosage, temperature and time, the total nitrogen effect of lignite adsorption coal chemical gasification wastewater was studied by Hach DR3900 spectrophotometer.When the amount of lignite reaches 400 g/L, the removal rate of total nitrogen can reach nearly 60%.The method of removing lignite from wastewater by using lignite as adsorbent can be used as a pretreatment for coal chemical wastewater treatment.
