组合芬顿技术深度处理化肥废水
Combined Fenton Technology for Advanced Treatment of Fertilizer Wastewater
摘要
Abstract
The quality of fertilizer wastewater is complicated,and it is difficult to obtain good results by physical and biological methods in advanced treatment technology.Aiming at the goal of zero discharge of chemical fertilizer enterprises,the oxidation treatment effects of five different advanced oxidation processes including flocculation system,Fenton system,ozone system,Fenton/O3 system and Fenton-PFS system on CODCr of chemical fertilizer wastewater under different conditions(dosage and time)were compared and screened.The results showed that the traditional flocculation process with reaction time of 5 min had the lowest effluent CODCr value(19.59 mg/L),the highest CODCr removal rate and the lowest cost(0.065 yuan/t).The CODCr treatment effect of the combined process based on Fenton reaction is not as good as that of the traditional Fenton system.The research is expected to provide an effective way to treat fertilizer wastewater.关键词
