Abstract
The invention relates to a method for controlling biological waste purification plants, especially those using an activated sludge tank with a final sedimentation tank (1) attached thereto. Sludge, preferably from the overflow of the activated sludge tank (13), especially in front of the mouth of the overflow, is fed to the final sedimentation tank (14). On the basis of the supernatant collected in the sedimentation tank, measured values characterizing said supernatant are detected such as chemical concentrations (i.e. oxygen, nitrate, ammonium, phosphate), physical parameters (i.e. pH value, redox potential, color) and totalizing parameters, i.e. chemical oxygen requirement (CSB), biological oxygen requirement (BSB), total content (TOC) of organic carbon either by taking and analyzing samples or by irradiating the vessels or conducting in situ measurements. The measured values thus obtained are used for controlling sludge feeding and/or recirculating the activated sludge (from the final sedimentation tank) and/or recycling oxygen into the activated sludge tank and/or operating an effluent compensation tank and/or proportioning additives (i.e. nutrients, sedimentation additives, precipitating agents, pH regulating agents) and/or controlling denitrification and/or proportioning non-continuously emerging currents, i.e. resulting from pit evacuation or the attached industrial plants or water recycled during sludge pressing.
