Study On The Liquid Discharge Catalytic Technology By AC Power

Recent years, with the rapid development of human industry, wastewater emissions are increasing year by year, the number of pollution sources with organic wastewater is growing more and more, water pollution tend diversification. High concentration of refractory organic wastewater has brought serious harm to human health.Traditional water treatment methods can effectively degradable organic wastewater, but there are still many deficiencies. So,Liquid phase discharge technology for treatment of organic wastewater with high treatment efficiency, No secondary pollution etc, become the hot issues in the study of organic wastewater treatment.In this thesis, using AC power, titanium aluminum electrode, sodium silicate as the experimental structure, We use the discharge catalytic dealing with rhodamine B simulated organic wastewater.Through the study of the macroscopic law of Titanium aluminum electrode degradation of rhodamine B,the Analysis of electrode combination of the characteristics of the effect of the impact of Rhodamine B, the observation of discharge phenomena,We discussed the Mechanism about Titanium aluminum electrode discharge degradation of Rhodamine B.The main content of this paper is as follows:1.Through the study of the macroscopic law of Titanium aluminum electrode degradation of rhodamine B, The degradation reaction of rhodamine B follow the first order kinetics. According to the experimental data and analysis, The available experimental titanium alloy (Ti:Al 70:30) electrode under the optimal experimental conditions, the processing time of 45min after simulated dyeing wastewater treatment effect for rhodamine B can be up to 89%.2. Through the study of titanium aluminum electrode discharge catalyst system, Alloy electrode compared with pure aluminum, titanium electrode in sodium silicate electrolyte and phosphoric acid electrolyte, marking the effect of organic dyeing and printing wastewater degradation of rhodamine B simulation.The experimental results show that titanium aluminum alloy electrode has certain advantages in both the electrolyte.3. On the basis of the above conclusions of the study, The treatment effect of the alloy and aluminum electrode in sodium silicate electrolyte organic dyeing wastewater for the simulation of rhodamine B Close to the treatment effect of the alloy electrode.4. Through the spectrum analysis, and verifies the titanium aluminum electrode discharge degradation of rhodamine B catalytic mechanism.From the mentioned above, it is known that the titanium alloy electrode has advantages in a certain extent. In this study, further research is needed, to explore more of these mechanisms, in order to be applied in real wastewater treatment.
