<p>A device for the treatment/purification of sewage effluent comprises three zones or levels (I, II, III) in which are performed a filtering of sludge, an aerobic treatment and an anaerobic treatment of the effluent respectively. These treatment stages are all provided in a joint, closed device in the form of a container (1) which is connected to the environment only via an inlet (2) for effluent which is to be treated and an outlet (3) for purified effluent. The device is so designed that precipitated substances, such as sludge and aerobically acting substances (11) can be replaced when required.</p> |
