METHOD OF WASTE WATERS CLEANING BY MEANS OF ACTIVATION PROCESS AND EQUIPMENT FOR REALIZATION OF THIS METHOD

摘要

The solution concerns the purification of sewage water by the activation process and the device for the application of this method, where the activity of the mixed culture of the activated sludge in the activation tank is used and it consists of the zone of the regenerator and contactor, which is subdivided into the oxic and anoxic part. The return sludge is brought from the final sedimentation tank to the anoxic part of the contactor zone through the regenerator zone. Before the entry into the contactor zone, the part exceeding the capacity of the activated sludge, which is located in the contactor zone, is separated from the purified sewage water. This part is brought into the regenerator zone, from where the equivalent amount of the activated sludge, accumulated in the regenerator zone, is brought into the anoxic part of the contactor zone. The solution falls within the area of water management and environmental protection.
