<p>#CMT# #/CMT# The arrangement for draining sewage sludge and/or slurries from sewage treatment plant with an integrated composting, comprises a conveyor pipeline (7), a compressor, and a baffle plate. The arrangement is located in a sedimentation tank (5) at its bottom or at a settling area of a suction basket (3) having suction holes distributed at its circumference. The suction basket has a riser pipe (2) at its upper side at an angle of 90[deg] to conveying direction of the sewage sludge and/or slurries. The riser pipe has an air inlet pipe for compressed air. #CMT# : #/CMT# The arrangement for draining sewage sludge and/or slurries from sewage treatment plant with an integrated composting, comprises a conveyor pipeline (7), a compressor, and a baffle plate. The arrangement is located in a sedimentation tank (5) at its bottom or at a settling area of a suction basket (3) having suction holes distributed at its circumference. The suction basket has a riser pipe (2) at its upper side at an angle of 90[deg] to conveying direction of the sewage sludge and/or slurries. The riser pipe has an air inlet pipe for compressed air, which flows to a downpipe, which is vertically guided to a drainage tank and a separator having a discharge hopper at its bottom side for recycling water. The separator is parallely guided into the sedimentation tank nearer to an inlet (15) for the sewage loaded with slurries. The conveyor pipeline is provided between the vertical position of the downpipe and the vertical portion of the riser pipe with a slope in direction of the downpipe. The compressor introduces the compressed air through the air inlet pipe into the riser pipe, where the air inlet pipe is attached to the riser pipe on upper side of the suction basket. The suction holes have smaller diameter than the diameter of the riser pipe. The separator stands over a bioair cleaner, which is filled with a natural substrate, in active connection with odorless environment. The downpipe has a ventilator at its upper end. The sedimentation tank is connected with a partition wall having a container, where a biological sewage treatment is supplied by an overflow of the sewage. The baffle plate is attached below the downpipe projecting into the drainage tank so that a floating layer of sewage sludge and/or slurries is acted upon from the downside. #CMT#USE : #/CMT# The arrangement is useful for draining of sewage sludge and/or slurries from sewage treatment plant. #CMT#ADVANTAGE : #/CMT# The arrangement is capable of simply and economically draining of sewage sludge and/or slurries from sewage treatment plant. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a sectional view of an arrangement for draining of sewage sludge and/or slurries. 2 : Riser pipe 3 : Suction basket 5 : Sedimentation tank 7 : Conveyor pipeline 15 : Inlet.</p> |
