Study on the Treatment of Washing and Bleaching Effluent in Papermaking Industry
Abstract: Waste water has carried out the main body of a book on to drifting along curdling to sedimentation the middle piece handling a paper making studying, investigation and discussion drift along curdling to have ascertained the best as well as stage p H value drifting along curdling to throw the effect adding amounts wait for a factor to paper making middle piece waste water COD and chroma takeoff rate dose, handling condition. The chlorinating aluminium , high ferric chloride , sulfuric acid iron , aluminum sulfate having wielded CPAM flocculant (FC265 , FC268) , having
got together in the experiment carry out a flocculation on waste water , flocculation effect is best when 3 mL , pH value having inspected the effect adding amounts , pH value to flocculation effect , having ascertained that to select and use the polymerization chlorinating aluminium adding amounts are 8.
