Automatic treatment device for sludge solidification tail water

The utility model relates to an automatic treatment device for sludge solidification tail water, which is characterized in that a first sedimentation tank is communicated with a second sedimentation tank through a first pipeline in a self-flowing manner, and a water flow meter is arranged at a water outlet of the first sedimentation tank; a PAM adding point and a PAC adding point are arranged on the first pipeline in the water flow direction, and a water level difference exists between the PAM adding point and the PAC adding point; chemical outlets of the PAM mixing tank and the PAC mixing tank are respectively communicated with a PAM adding point and a PAC adding point on the first pipeline. The method has the beneficial effects that the PAC and the PAM are adopted to treat the tail water, so that the residual PAC in the filter-press tail water can be fully utilized in time, and the agent loss is reduced; the PAM feeding point and the PAC feeding point have water level difference, and the impact force of wat
