Abstract
Industrial effluents containing mono- or polyhydris phenols, thiosulphates or thiocyanates, e.g. gas-works effluents such as those from ammonia stills, are aerated in the presence of aerobic micro-organisms capable of oxidizing the specified substances, the process being effected without the addition of sewage or the return of settled sludge to the effluent. The process may be effected in a tower filled with packing inoculated with the micro-organism, the effluent being circulated through the tower and an associated sump and air being passed in counterflow to the effluent. Alternatively, the process may be effected in a tank either by vortex aeration or by passage of air into the tank, and in the latter case the air leaving the tank may be passed to a tower in which foam is destroyed by an anti-foaming agent. In any p event the process may be effected in a number of stages, treatment with a micro-organism suitable for the oxidation of one of the specified substances being followed by treatment with another micro-organism suitable for the oxidation of another of the substances, and between the stages the effluent may be given a non-biological treatment, e.g. sterilization or flocculation, particularly in cases where the reaction products in one stage would adversely affect the micro-organisms used in a later stage. The micro-organisms may comprise bacteria, yeasts or filamentous organisms and nutrient materials therefore, e.g. phosphates, are added to the effluents, if necessary.
