DBD處理磺普羅胺的效能及機理研究
[Abstract]:In the past 30 years , the research on toxic pollutants mainly focuses on industrial chemicals and pesticides , and the research on pharmaceutical and personal care products ( PPCPs ) has only over 10 years of history . With the development of economy and the improvement of quality of life , the yield and dosage of these compounds are increasing , and the structure becomes more complicated . The removal of PPCPs pollutants has become the hot spot of research .
Iodinated Contrast Media ( ICM ) , as a typical PPCPs substance , directly excludes in vitro and enters the city sewage without metabolism in human body , and the iodide contrast agent has biological inertness and durability .
In this study , the typical iodide contrast agent _ iprodine was chosen as the research object , and the detection method of solid - phase extraction - high performance liquid chromatography ( SPE - HPLC ) was established for the problem of low iodine propamide content in the water environment . The relationship between the input power and output power and the degradation performance of the double - media barrier discharge reaction kettle were optimized . The results show that the linear equation is y = 0.0595x - 0.993 79 and the correlation coefficient is 0.998 92 .
Degradation of acetic acid and lemon yellow indicates that the efficiency of oxidizing active particles such as CH , etc . due to double dielectric barrier discharge is high , which can be used for the degradation of iodine propamide difficult to degrade .
On the basis of the above research , the optimal condition of treatment of iodine propamine wastewater by double dielectric barrier discharge reaction kettle is explored . The results show that the increase of the input power and the increase of reaction time are beneficial to the removal rate of iodine propamide . The optimum conditions are as follows : the input voltage is 50V , the current is 1.08A , the reaction time is 10min , the removal rate of iodine propamide reaches 100 % , TOC removal rate is less , but B / C is effectively used to decompose the iodine propamide macromolecule into small molecule organic matter , but the result of biological treatment in the input plasma reaction system is verified by the above conclusion , and the effluent quality basically reaches the first - level A discharge standard of the municipal sewage treatment plant .
The results show that the removal rate of iodine propamide is not less than 5 g / L and the removal rate is less than 5 g / L . In addition , the activated carbon filtration stage in the conventional water supply process has the advantages of simple process , short reaction time and good removal effect .
The kinetic equation of degradation kinetic equation is C = C0 脳 e - 0.1349t .
The energy utilization ratio and the energy utilization ratio of the plasma process were only 9.6 脳 10 - 7 / J , 1.43X 10 - 8 mol / J and 3.1 脳 10 - 8 mol / J , respectively .
