Abstract：

The　resin　adsorption　process　has　been　developed　to　remove　phenols　from　coking　wastewater　and　its　technological　parameters　are　optimized.　The　results　show　that　the　ultra-cross　linking　adsorption　resin,　NDA-99,　is　an　effective　adsorbent　to　treat　the　coking　waste　water　when　its　pH　is　4.0　and　the　absorbing　flux　is　40mL/h,　and　the　mono-column　wastewater　treatment　capacity　is　300mL　per　batch.　Under　the　condition　of　50C,　10mL8%　NaOH　+10mL4%　NaOH+20mLwater　is　selected　as　the　desorption　reagent,　and　the　flux　is　10mL/h.　After　the　treatment　process,　the　concentrations　of　volatile　phenol　and　COD　decrease　from　about　1　380mg/L　to　12mg/L,　and　15　500mg/L　to　less　than　650　mg/L　respectively.　The　raw　phenol　desorption　solution　can　be　recovered　just　as　the　high　concentration　desorption　solution　by　isopropyl　ether　extraction-distillation.　Thus,　the　resource　recycle　of　phenol　in　coking　wastewater　is　carried　out.　©2009　IEEE.
