Title: Treatment of effluent from coking factories - sepn. of ammonia and phenol cpds. prior to biological treatment
IPC: C02F1/20
Filed: 1978-04-17
Abstract: The effluent enters the top of a stripping column in which the volatile ammonia cpds. are carried away by the stripping agent (steam). At the bottom of the tower, Ca (hydr) oxide is fed into the stripped effluent and the reaction products overflow to a second vessel where the clear water and the residue separate by means of filtration under vacume. Alternatively, the residue and clear water may be sepd by a simple setting process, by centrifugal force or by the use of a precipitating agent. The ammonia cpds. freed in the alkali reaction and recovered in the second vessel may be turbulently mixed with acid and returned to the stripping column below the point at which the calcium oxide or hydroxide enters. Small quantities of ammonia or phenol cpds. in effluent will disrupt the normal biological waste treatment process. By eliminating these cpds. it is possible to pass the clear water produced into the biological process without any harmful effects. The process is particularly applicable to the coke industries.
