Study on Using Coking Wastewater to Prepare Low-Rank CWS and its Rheology Changes at Different Temperatures

Abstract:

Regarded as an effective treatment to many kinds of industry wastewater, CWS technology is introduced to treat coking-wastewater, to simplify treating procedure. A low rank coal from Ximeng (in China) was prepared to slurry with clean water and three kind of wastewater at different treating depth. The results indicated that: (1) the coking-wastewater performed a slightly better effect than the clean water for preparing CWS; (2) the apparent viscosity decreases rapidly by heating the slurry, but increases when the temperature reaches to a unique value. The value is 40°C for cleaning-workshop feed CWS, 30°C for membrane filter feed CWS, and 50°C for membrane filter underflow.
