[0036] With the above structure, raw water, i.e. sewage, is transported to the first-stage treatment unit 100. According to the raw water index and the effluent requirement index, new activated carbon is quantitatively fed into the first working tank through the first feeding component to carry out activated carbon adsorption treatment. In the first working tank, the raw water and the new activated carbon are fully mixed, and the adsorption saturated primary waste activated carbon and the sewage enter the first solid-liquid separation equipment together for solid-liquid separation. The primary effluent produced by the solid-liquid separation enters the second working tank of the second-stage treatment unit 200 for further treatment.
