甲胺/DMF装置废水回用试验及运行情况
Methylamine/DMF Unit Wastewater Reuse Experiment and Its Operation Conditions
,
摘要:

甲胺/DMF装置废水中有机物含量高、COD含量波动大,废水水质极不稳定,致使废水处理站活性污泥大量死亡,SBR池表面黏性浮泥严重,厌氧池失去功效无法启动,废水处理站完全失效。经研究和试验,决定将甲胺装置的废水全部引入多元料浆磨煤系统作为水煤浆制备用水。改造后经近3年的运行,气化装置工艺稳定、设备运转正常,表明高浓度有机废水回用成功。

Abstract:

The high organic content, large fluctuation in COD content, extremely unstable water quality of methylamine/DMF unit wastewater causes wastewater treatment station activated sludge died in large numbers, a lot of sticky float sludge on SBR pool surface, anaerobic pool lost efficacy and unable to start, and the wastewater treatment station completely failed. After research and experiment, it is decided to introduce the methylamine unit wastewater to multi-component slurry pulverized coal system as coal water slurry preparation water. In last three years of operation after the revamp, the process of gasification unit is stable, equipment has run normally. It shows that the reuse of high concentration organic wastewater is a success.
