The utility model relates to an in-situ ecological purification treatment device for urban ditch sewage, belonging to the field of urban sewage ecological treatment. The present invention is in the city of ditch network, set up the earthworm bioreactor, biological barrier, water aeration water distributor, turbine rotating biological contactor, ecological purification function area and aeration filtration system. Its characteristic is water aeration water distributor is communicated through the water inlet overflow water distribution plate and earthworm biological reactor, earthworm biological reactor outlet and ecological purification function area of aquatic plant area is communicated with the hydraulic rotating biological contactor is arranged in the earthworm biological reactor outlet channel. Compared with commonly used at home and abroad of the sewage treatment plant, not only can effectively utilize the city space of sewage ditch in situ purification treatment, the city sewage sewage for irrigation canals and ditches decontamination pay off, but also can make the city ditch network ecological restoration function, become the city beautification of the natural landscape.
