<p>This invention discloses a continuous-flow reactor for treating wastewater with high-concentration of nitrogen and phosphorus and the treating method thereof. The basic components in the reactor disclosed in this invention include a cylindrical influent protection weir with serrated slots, a cylindrical coagulating crystallizer, a funnel-like baffle for protecting static settling, a conical crystallizing static settler, a wall-attaching inclined plate settler and a wall-attaching effluent weir with serrated slots. The treating method disclosed in this invention includes the following stages: startup stage, leading wastewater into the cylindrical coagulating crystallizer and starting an agitator, then adding in the soluble magnesium and adjusting the pH value to 7ˆ¼10; stabilization stage, leading the primary effluent back into the reactor for a second treatment; when the removal rate of nitrogen and phosphorus in the effluent reaches 95% or higher, the effluent is able to be channeled out to the next treatment unit. This invention overcomes the limitations presented in the existing arts, such as complex working procedures, low treatment volume, great turbulent flow in the reactor and long precipitation duration, and consequently improves the effect of MAP crystallization and precipitation. In addition, the simple structure of the whole device disclosed herein is favorable for maintaining its stable working state.</p> |
