摘要

Process for removal of scum in the chambers of the system trifasico of anaerobic reactors.Using the mixture of foam with the sludge digested inside the reactor and its removal for the dehydration of natural or mechanical, without the loss of physical stability and the organic sludge blanket.Using to this end suction systems for the recirculation of foaming and cleaning system and spraying with water or sewage treated.To understand the present invention patent a process and its automatic equipment to mix.The recirculation and the incorporation of the foam formed on the surface of the three-phase separators to the iodine digested, in view of its removal and proper disposal.Called "system of mixture of scum and sludge - smel.In which provides recirculation of scum generated 24 hours a day, without the loss of organic and physical stability of the blanket of sludge with better use of biogas generated in the process.Characterized by the set of channels "hoods in 60", piping system, records and connections, set the bike pump and cleaning system and water spray.Which provides two alternatives (processes) of the recirculation where each alternative has specific features and functionality.The first alternative is characterized by recirculation of scum to the top of the reactor, where it is distributed to the interior of the reactor along with the sewage influent.Allowing the scum generated in the treatment process, is mixed and incorporated into the digested sludge to be removed together with the iodine digested by Descartes periodicals.The second alternative is characterized by recirculation of scum to the inner part and the lower part of the reactor below the blanket of sludge.Using master pipe consisting of derivations with the recording of return, compatible with the same positioning from the point of arrival of the drainage tributaries in the bottom of the reactor.
