  • Patent number: 8721886
    Abstract: Provided are an apparatus and a method for river water purification using a treatment soil layer and a permeable filtering medium layer. The river water purification apparatus includes a treatment soil layer and a permeable filtering medium layer which are sequentially and alternately stacked. The treatment soil layer includes a plurality of unit soil layers which are arranged at intervals. A reservoir part which stores a predetermined amount of river water and supplies the river water to an inside of the unit soil layer is provided in an upper end part of the unit soil layer. The permeable filtering medium layer has a higher hydraulic conductivity than that of the treatment soil layer. The river water purification apparatus increases a treatment flux of river water regardless of a coefficient of water permeability of soil and effectively removes nitrogen, phosphorus and nutrient salts by stably forming an anaerobic condition.

  • Publication number: 20130168325
    Abstract: Provided are an apparatus for removing phosphorous from wastewater including: a first coagulation sedimentation unit including a first rapid mixing tank, a first flocculation tank and a first sedimentation tank; and a second coagulation sedimentation unit including a second rapid mixing tank, a second flocculation tank and a second sedimentation tank, and a method for removing phosphorous using the same. The first rapid mixing tank stirs wastewater and an inorganic coagulant with low basicity at high speed and the second rapid mixing tank stirs the treated water supplied from the first sedimentation tank and an inorganic coagulant with high basicity at high speed. As a result, removal of phosphorous from the wastewater is maximized and coagulation and sedimentation may be optimized through control of metal content in the inorganic coagulants added to the first rapid mixing tank and the second rapid mixing tank.
