According to the technical scheme, when the discharged sewage does not reach the standard or an original sewage treatment system fails, the sewage is conveyed to a mixing tank through a water inlet pipe, the PH value of the sewage is adjusted by adding an acidic or alkaline agent into the sewage, then a treatment agent is added into a mixing agent adding pipe aiming at the condition that the sewage exceeds the standard, the mixing time in the mixing tank is about 2min, the mixed sewage is conveyed to a flocculation tank through a first connecting pipe, the end part of the first connecting pipe extends into a guide cylinder, the first connecting pipe is mixed with the agent added into the flocculation agent adding pipe in the guide cylinder, the mixture is fully stirred under the action of a flocculation stirring device, the flow velocity in the guide cylinder reaches 0.6m/s, the flow velocity outside the guide cylinder reaches 0.2m/s, the flow velocity in the water distribution baffle reaches 0.8m/s under the action of the water distribution baffle, then the sewage enters a sedimentation tank, the sludge in the sedimentation tank is precipitated inside a sludge hopper, and the supernatant enters the effluent area through an inclined pipeline, and the water at the top layer is gradually discharged through the arrangement of an overflow weir. Because the design of the pipeline of slope, the fluctuation that can effectively reduce the water in the sedimentation tank produces the influence to the aquatic in the play pool for the water in the play pool is more steady, even if the aquatic in the play pool contains a small amount of mud, also can subside, in the sludge bucket that gets into the sedimentation tank along the pipeline, makes the water in play pool more limpid clean, accords with emission standard. Certainly, the sludge return pipe is arranged on the sludge hopper and can also be arranged on the sedimentation tank above the sludge hopper, and the sludge is returned to the flocculation tank through the sludge return pipe, because of the coagulant, the flocculant and the active sludgeThe flocculation capacity of the sewage is enhanced due to the backflow of the slag, the sedimentation effect is good, the quality of the effluent is stable, and the surface load can reach 15m3/（m2·h）。
In addition, the above scheme only needs the mixing tank, the flocculation tank and the sedimentation tank, the occupied area is small, and the sewage treatment is fast-connected and efficient.
The structure of the mixing and stirring device and the structure of the flocculation stirring device both comprise a variable frequency motor, a stirring shaft and stirring blades, and the stirring blades of the flocculation stirring device are positioned inside the guide cylinder. The design of this structure can be more stable to the stirring of sewage.
The utility model provides an outer mud emergency treatment device of arranging, it can effectively realize the rapid processing to outer mud of arranging through reasonable structural design, and the device area occupied is little, and operating stability is high.
