| titleOfInvention | Method and apparatus for treating nitrate nitrogen and phosphorus-containing water |
| abstract | A processing method and apparatus capable of easily and simultaneously removing nitrate nitrogen and phosphorus in waste water. SOLUTION: Treated water containing nitrate nitrogen and phosphorus is denitrified by a denitrifying agent containing sulfur and calcium carbonate as main components carrying sulfur oxidizing bacteria, and then alkaline earth metal silicate such as rock wool. Dephosphorization is performed using a salt-containing inorganic fiber as a base material and a dephosphorizing agent composed of a mixture with a hydraulic material such as cement or an alkali material. A denitrification unit A filled with the denitrification agent 4 and a dephosphorization unit B filled with the dephosphorization agent 9 are provided. The denitrification unit A has a treated water supply port 1 and the dephosphorization unit B has a treated water discharge port. 8. An apparatus for treating nitrate-nitrogen- and phosphorus-containing water, wherein each unit has a structure in which water to be treated flows from a lower part to an upper part and the water to be treated overflows. Preferably, a height difference is provided between the denitrification unit A and the dephosphorization unit B, and the denitrification unit B is installed so that the water level is lowered.
