The Research On Emergency Treatment Of Dringking Water Polluted By Phenol

Recently, as industrialization and urbanization developing rapidly, the industrybooms. Although does people get a lot, it brings lots of bad effects. The pollutions ofwater resources are more and more serious. The number and the range of polluted waterresources is increasing. In addition, the number of sudden water pollutions is increasingjust because of the long-distance transportation. All of these are huge threats to thewaterworks and the residents.The conventional water treatment process which is used to treat slightly pollutedwater can’t remove the organic pollutants effectively. If the water resources are polluted,the water quality will get worse rapidly and can’t reach the water quality standards. Soon the base of the others’ literatures, I choose the phenol which is easier to be thepollution resource and more dangerous as the object of study according to thepollutants’ types, kinds, ranges and degrees of the water pollutions recently. Offer thewater treatment technology for sudden phenol pollutions by strengthening andoptimizing the conventional water treatment process, and at last supports sudden phenolwater pollutions.According to the properties of phenol and characteristic and requirements ofemergency water treatment, I choose adsorption and oxidation as the core processingtechnology. At first, explore how the adsorption, oxidation and coagulation affects thephenol’s removal rate. Take the types, aperture and dosage of activated carbon,temperature, pH and the reaction time as the influential factors of the adsorptionreaction. Take the dosage of the oxidant, pH and the initial phenol concentration as theinfluential factors of the oxidation reaction. Check how the number of coagulant affectsthe removal rate. Secondly, explore how the combined technology affects the phenol’sremoval rate. Take the dosing order and dosage of chemical reagents as the influentialfactors. At last, exam the combined technology’s cost according to engineeringeconomic analysis.Get every technology’s best parameters according to the results of each processused only. Such as pH，adsorption reaction time，the best dosage of activated carbon andoxidants. The combined technology’s results show it can really ensure the water quality.There is little difference between using activated carbon only and using activated carbonwith coagulant. The phenol removal rate of absorption after oxidation is higher than oxidation after absorption. The most important is that combined technology has a higherremoval rate. The oxidation-coagulation-absorption-precipitation-filtration processsupports emergency treatment well.The study combines the engineering practice closely and it is the guidance for thesudden phenol pollutions treatment. It can guide other organic sudden pollutions aswell.
