| Abstract |
To establish the efficient removal scheme of anion surfactants from car washing wastewater, the optimal conditions of aeration rate, duration of aeration and temperature were estimated. Anion surfactants in car washing wastewater was removed about 60% by the simple aeration(1.6ℓair/min for 7ℓ of wastewater), and the higher aeration rate was required at low temperature to get the similar removal rate. Considering the in situ temperature(10∼20℃), the aeration must be kept for 5∼6 hrs. Combining the biological method to the conventional method, the high removal rate more than 80% of anion surfactants could be achieved. |
