#CMT# #/CMT# The sewage treatment plant comprises a sand trap (1), a pumping station, and two clarifiers. A sedimentation tank and a connectable blower are also provided. The sand trap is constructed with an inlet (10) as an additional downstream mixing tank (5), in which another recirculated sludge pipe (15) is connected. The two clarifiers are constructed as a biological activated sludge tank, where the grit chamber is connected with downstream mixing tank over an overflow (11) in a biological activation tank (2). #CMT# : #/CMT# An independent claim is also included for a method for sewage treatment, which involves injecting the sewage in the clarifiers in a sewage treatment plant. #CMT#USE : #/CMT# Sewage treatment plant. #CMT#ADVANTAGE : #/CMT# The sewage treatment plant uses less energy and has significantly less mechanical complexity, and optimizes the sewage treatment method and minimizes the proportion of nitrogen and follows environmental legislation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the sewage treatment plant. 1 : Sand trap 2 : Biological activation tank 5 : Mixing tank 10 : Inlet 11 : Overflow 15 : Recirculated sludge pipe. |
