Abstract—Washing coal usually brings about wastewater ways must be explored to dispose phenol-cyanogen
(in terms of closed circulation) due to transpiration, which provides wastewater (hereinafter the short form coking reclaimed
an effective space for the recycle of coke-plant wastewater. The water) from biochemical on the recycling
effluent from phenol-cyanogen wastewater biochemical disposal economy, and the different requirements of the water quality in
station is used plementary water for washing coal, and Closed- the industrial chains of coal carbonization base, the idea of
Cycling System in coal preparation plant is introduced to make greater circulation has been put forward. By using phenol-
industrial experiment. Results show that we can use coal power cyanogen wastewater from the biochemical disposal station as
adsorption and ulation as well as sedimentation to treat the the coal washing water and introducing the washing water
