Ecological clean system in river course

The utility model provides an ecological clean system in river course, including being arranged in getting rid of the mud of sewage and the sedimentation treatment subsystem of suspended solid, be arranged in carrying sewage the municipal drainage subsystem of sedimentation treatment subsystem, the output and the input of sedimentation treatment subsystem of this municipal drainage subsystem are connected, an output is connected that is used for water purification's ecological processing subsystem, this ecology processing subsystem and sediment processing subsystem. The utility model discloses utilize the compound ecological processing technique who purifies, at first carry out physics through the sedimentation treatment subsystem to sewage and subside, adopt biological method to carry out ecology to sewage through ecological processing subsystem after that and purify, so this ecological clean system in river course is higher to the improvement efficiency that flows into the sewage in the river course, improved the water ecological environment in river course.
