Abstract
The coagulation methods and the Fenton oxidation were used to deal the wastewater which came from the release agent of the gear production process.The experiment is aimed at removing the COD concentration,improve the biodegradability of the wastewater and laying the groundwork for follow-up biochemical treatment.In the coagulation part,use the FeCl3,PAC and composite coagulant,contrast is drawn by the various parameters that when the dosage of PAC is 1 400mg/L,the pH of raw water is adjusted to 7.0,the precipitation time is 40min,the removal efficiency of COD is highest which can reach 96.8％.The conclusion comes from the Fenton oxidation is that when the dosage of H2O2 is 6.6g/L,H2O2/Fe2+ is 10,the pH of raw wastewater is 3.0,the reaction time is 60min,the best effect of the removal efficiency of COD could reach 88.4％.It can clearly be seen that for such wastewater use the coagulation processing which under the optimal conditions is the better choice.关键词
