| titleOfInvention | A kind of immersion, deflector type, the technique of the continuous ammonia nitrogen removal of closed hydrophobic membrane |
| abstract | The invention provides the new technology of a kind of immersion hydrophobic membrane ammonia nitrogen removal: first the pH of high ammonia-nitrogen wastewater is transferred to about 10, and regulation pH uses liquid sodium hydroxide or liquid calcium hydroxide.Waste water water outlet after cartridge filter coarse filtration after pH is adjusted enters and is soaked with the deflector type closed continuous ammonia nitrogen removal of runner reaction tank of curtain or pillar hydrophobic membrane, and ammonia nitrogen waste water up to standard is discharged continuously.Meanwhile, the inner side of hydrophobic membrane be passed through sulphuric acid, phosphoric acid or nitric acid, etc. acid solution as absorbing liquid, water outlet return to absorb liquid pool be circulated absorption ammonia nitrogen.Wherein, the mode of plural parallel stage and (or) series connection taked by submergence curtain or submergence pillar hydrophobic membrane assembly, the absorbance of total ammonia nitrogen up to 50 99%, equipment convenient operating maintenance.Also to ensure that ammonia nitrogen removal effect, need timing to carry out waste water and add alkali regulation PH and absorbing liquid benefit acid.After being absorbed by continuous hydrophobic film, the ammonia nitrogen concentration of waste water reaches requirement, enters other operation and continues with.The concentration of absorbing liquid ammonium sulfate or ammonium phosphate or ammonium nitrate is the highest can reach 30 40%. |
