Study On Treatment Of Landfill Leachate By Electrochemical Oxidation Process

The landfill leachate which quality is complex and organic substance content is high, other than treating efficiently the methods using to treat it nowadays are immature. Therefore the landfill leachate pollutes our environment seriously. This paper puts forward Electroche- mical Oxidation Process to treating landfill leachate, study on proximal condition .Managing GCMS survey fore-and-aft organic compounds , research the pretreatment method of sample and instrument's operate condition.Ensure the infection factors of Electrochemical Oxidation Process include of electricity density, pH value, temperature and adding NaCl in enter water et. At the same time, extract the leachate under the condition of acidity-mid- alkalescence, pass through centrifugal destr- oying emulsification and circumgyrating distillation condense, manage GCMS instrument, improve method of operation, measure the components of fore-and-aft leachate which dealed with or not.Using Electrochemical Oxidation Process treat landfill leachate , disposing 120min , ele- ctricity density 7.5A/dm², pole broad space between 10mm, anode material is SnO₂/Ti, catho- de material is stainless steel, adding NaCl 2g/100mL. When COD of enter water is 44100mg /L,out-thickness is 13697mg/L,rate of wiping off 68.94%; NH₃-N enter water is 4085mg/L , out-thickness is 1209mg/L,rate of wiping off 70.4%. Landfill leachate from black-gray turbid to white-translucence, the effect of wiping off SS is obviously.Choose Shimadzu GCMS-QP2010. After Electrochemical Oxidation Process,the substa- nce form of landfill leachate has changed clearly, choose the proper slope to check-up and find that complex and difficult and biodegraded organic compounds ulteriorly transform sim- ple and easy biodegraded organic compounds, not only redusing toxicity harm, but also adva- ncing the biodegradable quality of landfill leachate, or achieve the basis require of direct draining into urban sewage meshwork.On all accounts, the remarkable effect of Electrochemical Oxidation Process treat Landfill leachate .
