The invention provides full-automatic sewage concentration treatment equipment. A pre-separation stirring tank, magnetic recovery equipment, a magnetic powder adding system and a sedimentation tank with brand-new structures are provided, the magnetic powder recovery rate is high, the full-automatic sewage concentration treatment equipment occupies a small area, is suitable for new construction, especially for reconstruction of old water plants with tense sites, and is low in overall investment and construction cost; traditional reinforced concrete structures such as a concentration tank and a sludge storage tank are replaced, the automation degree is high, debugging and operation are simple and reliable, and unattended operation can be achieved. The full-automatic sewage concentration treatment equipment is short in sewage concentration time, the desliming efficiency of the desliming machine is greatly improved, and the low water content of discharged sludge is ensured. The equipment has the characteristics of stable and reliable operation, simple operation, small occupied area, high sewage concentration efficiency, large water treatment amount and low operation cost according to the current treatment situation of the sewage of the waterworks.
