Abstract
In this paper, the stripping method was used to deal with the wastewater with high concentration of ammonia generated in the industrial production process, and the effects of blowing time, waste water pH, stripping temperature and gas-liquid volume ratio on the maximum removal rate of ammonia were investigated by experiments. The experimental results show that the gas - liquid ratio is linear to the stripping efficiency at 50°C and strongly alkaline. And it can be deduced that the effect of different air flow rates on the blowout efficiency at gas-liquid ratio below 1000 is not significant. In this paper, the maximum air flow rate is 2L/min, and the maximum reaction time (stripping time) is 120min, so the maximum gas-liquid ratio is only 800. At the same time, this paper also explored the reaction mechanism of ammonia removal via the stripping method and its application in ammonia removal from industrial wastewater produced by monosodium glutamate.
