| Description | Journal: Iop Conference Series: Earth and Environmental Science $NH_{4} ^{+}$-N has become the main pollution factor affecting the surface water quality in China. Based on the theory of photolysis, the feasibility of photolysis removing $NH_{4} ^{+}$-N in surface water is studied. The effects of pH, $CaO_{2}$ content and photolysis time on removal rate of $NH_{4} ^{+}$-N are studied. The actual study is based on Laboratory studies results. Experimental results show: When the pH8, the photolysis can greatly reduce the $NH_{4} ^{+}$-N content in water. $CaO_{2}$ can greatly remove $NH_{4} ^{+}$-N. The removal rate of $NH_{4} ^{+}$-N increased with the increase of photocatalytic time. When irradiated with UV light for 108 hours or the sun is irradiated for about 40 days, $NH_{4} ^{+}$-N content can be reduced from 4mg/L to 0.5mg/L under the optimum experimental conditions. Adjusting the pH of surface water is the most important condition for controlling $NH_{4} ^{+}$-N content. |
