<p>The invention relates to a process for purifying effluent in anaerobic reactor, in which the microorganisms are held by supports, the supports forming an immovable bed which is fixed in a part of the reactor.The process is characterized in that the reactor is backwashed once it has been at least partially clogged, by temporarily suspending the supports. Advantageously, the process comprises an initial step for starting the reactor, during which the load of the reactor is increased with a short and constant hydraulic residence time.</p> |
