Treatment of a high-strength phenolic and ammonia waste stream by single and multistage activated-sludge process
Pilot-scale studies were conducted on the design of an activated-sludge process for purification of evaporator condensate from a coke oven plant. The liquor from the quenching process was treated by multistage flash evaporation to give a condensate which contained phenol at 4000 mg/l. and ammonia at 500 mg/l. Sludge obtained from an industrial waste treatment pilot plant and acclimated to the required levels of phenols and ammonia were tested for removal of BOD and COD. Correlations were established between the residual levels of phenols and organic sludge loading, and also between the degree of nitrification, residual cyanide levels and sludge loading. The phenol concentration could be reduced to Vertical Bar3; 0.5 mg/l. under fairly constant loading conditions; nitrification was capable of proceeding simultaneously and was not inhibited by cyanide at up to 3.5 mg/l. in the incoming liquor.
