Abstract

The biological purification plant comprises a tank to hold the sewage to be purified having an oxygenation area and an area for pouring out the mud, an air delivery line fitted with a blower fan with diffusers placed in the oxygenation area of the tank, and a line for recirculating the mud from the pouring area to the oxygenation area of the tank. For extracting the mud from the tank, a discharge line is provided that is immersed in the pouring area and from which the recirculating line branches. To this discharge line are connected ejector devices fed with air supplied by the said blower fan so as to produce the flow of mud inside the said discharge line. Valve devices are able to control the direction of flow of the mud alternately to the recirculating line or the discharge. <IMAGE>
