摘要： PURPOSE: To remove ammonia in good efficiency, by adding a scale dispersant in an ammonium sulfate solution prior to introducing the ammonium sulfate solution having slaked lime added thereto into a still and a thermocompressor to prevent the clogging due to slaked lime.
CONSTITUTION: The ammonium sulfate solution 2
1 in an ammonium sulfate tank 1 is introduced into a first still 6 through a prefilter 3 and heat exchangers 4, 5 and, after free ammonia 8 in the ammonium sulfate solution 2
1 is removed by steam 7, the treated solution is passed through a heat exchanger 5 to be introduced into a reaction tank 9 where slaked lime 10 is added. In the next step, the ammonium sulfate solution 2
3 in the reaction tank 9 is introduced into a thickener 11 and, after slaked lime and reaction substances are precipitated and removed, the treated solution is introduced into a stock liquid tank 12 to be added with a scale dispersant 13 in an amount of 5W100ppm per 1m
2 ammonium sulfate solution. The dispersant added solution is introduced into a second still 14 to remove free ammonia in the ammonium sulfate solution 2
4 by steam 15
1 and the treated solution is introduced into a thermocompressor 16 to be further subjected to activation treatment through a heat exchanger 4.

摘要： PURPOSE: To perform treatment of waste liquid of high ammonia concn. without pretreatment or dilution by adjusting the concn. of dissolved oxygen in an aeration tank contg. waste liquid of high ammonia concn. to 0.1W0.5ppm and performing treatment with activated sludge for the adjusted waste liquid.
CONSTITUTION: Ammonia liquor having 5,000ppm ammonia concn. is charged to an aeration tank and aerated to 0.3ppm dissolved oxygen. and then subjected to the treatment with activated sludge. As the result, SCN
- is held always at ≤3ppm; the superiority of the performance of the treatment is thus recognized. The control of the dissolved oxygen in the aeration tank is performed by the control of the working number of stirrers in accordance with detection signals issued by a measuring instrument for the dissolved oxygen installed in the aeration tank, or by other means. For the control of the dissolved oxygen, it is desirable to use simultaneously oxidation-reduction potential and pH as the measure for the operation. By this way, treatment of waste liquid of high ammonia concn. is possible without dilution.
