【摘要】：在自制電化學(xué)反應(yīng)器中,進(jìn)行三維電極-紫外光氧化法對(duì)堿性品綠溶液色度去除的實(shí)驗(yàn),分析電解質(zhì)投加量、電極間距、電壓、初始pH、曝氣量等因素對(duì)堿性品綠脫色率的影響,并對(duì)比了紫外光氧化法、二維電極法、三維電極法、三維電極-紫外光氧化法在相同條件下對(duì)堿性品綠的去除效果。結(jié)果表明,三維電極-紫外光氧化法處理堿性品綠的優(yōu)化工藝條件為:電解質(zhì)Na_2SO_4投加量1 g/L,主電極極間距7 cm,電壓15 V,初始p H為3,曝氣體積流量13L/min。在此優(yōu)化條件下,堿性品綠的脫色率達(dá)到99.44%,明顯優(yōu)于其他方法。三維電極-紫外光氧化法能夠有效降解廢水中的有機(jī)物,對(duì)堿性品綠的處理效果較好。
[Abstract]:In a self-made electrochemical reactor, the three-dimensional electrode-UV oxidation method was used to remove the chromaticity of alkaline green solution. The electrolyte dosage, electrode spacing, voltage and initial pH, were analyzed. The effects of aeration and other factors on the decolorization rate of alkaline green were compared with those of ultraviolet photooxidation, two-dimensional electrode method and three-dimensional electrode-UV oxidation under the same conditions. The results show that the optimum technological conditions for the treatment of alkaline green by three-dimensional electrode-UV oxidation are as follows: the dosage of electrolyte Na_2SO_4 is 1 g / L, the main electrode spacing is 7 cm, voltage 15 V, the initial pH is 3, Aeration volume flow rate is 13 L 路min ~ (- 1). Under the optimized conditions, the decolorization rate of alkaline green is 99.44%, which is obviously better than other methods. The three-dimensional electrode-UV oxidation can effectively degrade the organic matter in the wastewater, and the treatment effect of alkaline green is better than that of the three-dimensional electrode-UV oxidation.
