Abstract

PURPOSE: To utilize a sodium carbonate crude sodium bicarbonate mixed liquid as an alkali agent availably by adding a sodium carbonate.crude sodium bicarbonate mixed liquid generated when tar acid sodium salt is subjected to the carbonic acid decomposition to a gas liquid before the activated sludge treatment.
CONSTITUTION: The coal tar formed during dry distillation of coal is converted to tar acid sodium salt when it is subjected to the separation treatment from a coke furnace, but, if this tar acid sodium salt is introduced into a carbonic acid decomposition tower 1 to carry out the carbonic acid decomposition, a sodium carbonate. crude sodium bicarbonate mixed liquid is formed and stored in an intermediate tank 3 and, after tar acid is removed, stored in a storage tank 5. Thereafter, if this sodium carbonate.crude sodium bicarbonate mixed liquid is added to a gas liquid before the activated sludge treatment, it functions as an alkali agent and the removal and/or the pH adjustment of ammonia is carried out. As described above, the sodium carbonate.crude sodium bicarbonate mixed liquid is utilized availably.
