| titleOfInvention | A nitrate reduction apparatus and method using chemicals |
| abstract | The present invention is configured by dualizing the mixing tank and the reaction tank to enable continuous nitrogen treatment, to maximize the recovery rate of zinc (Zn), and the site for nitrogen removal compared to the site required for treatment by microorganisms 1 / The present invention relates to a nitrogen removal apparatus and method using chemicals that can be reduced to 10 and applicable to high concentration industrial wastewater of up to 120,000 mg / L.n n n The present invention, the first mixing tank in which waste, sewage flows from the outside; Chemical chemical injection means for injecting chemical chemical which is a catalyst for causing a chemical reaction in the first mixing tank; A plurality of anode plate and a plate plate plated with zinc are provided therein at predetermined intervals, and the nitrate and nitrite contained in the waste sewage are reacted with zinc in waste and sewage which is mixed with chemicals in the first mixing tank. At least one reaction means converted into nitrogen gas and discharged into the atmosphere; Power supply means for supplying power to each of the at least one reaction means so that zinc, which is melted from the anode plating plate during zinc reaction, is reattached to the cathode plate by electrolysis; And it provides a nitrogen removal apparatus using a chemical agent comprising a pH adjusting means for adjusting the pH of the treated water passed through the reaction means to discharge the neutral state.n n n In addition, the present invention is a first step of mixing by injecting a reaction catalyst into the first mixing tank in which waste, sewage flows; A second step of contacting the waste and sewage in which the reaction catalyst is mixed with a zinc plated negative electrode plate in a first reactor, and releasing nitrogen gas converted into a chemical reaction between zinc, nitrate, and nitrite into the atmosphere; A third step of supplying power to the first reactor to attach ionized zinc to the negative electrode plate after the chemical reaction; A fourth step of flowing the first treated water having passed through the first reaction tank into a second mixing tank, injecting a reaction catalyst, and mixing again; A fifth step of contacting the first treatment water mixed with the reaction catalyst with the zinc plated negative electrode plate in the second reaction tank and releasing nitrogen gas changed by the chemical reaction between residual nitrate and nitrite contained in the first treatment water to zinc into the atmosphere; ; A sixth step of supplying power to the second reactor to attach ionized zinc to the negative electrode plate after the chemical reaction; And it provides a nitrogen removal method using a chemical comprising a seventh step of adjusting the pH of the treated water passed through the second reaction tank to be discharged after the neutral. |
