Studies on the Wastewater Treatment and Wastewater Characteristics from Acetaldehyde
아세트 알데히드 공장 폐수의 특성 및 화학적 처리
Abstract
As a research for treatment of wastewater from acetaldehyde plant by biological method, we investigated general characteristics of the wastewater as well as the effect of coagulants. COD and BOD of the wastewater were 5260 ppm and 6452 ppm, respectively, and pH was 1.86. COD and BOD of the wastewater were 214, 000ppm and 15190ppm, respectively, and pH was 2.4. And the main organic componnt in wastewater were acetic acid were contained 6.76 % and 14.5 %, respectively. FeSO$_{4}$ as the coagulated was the most effective. The COD removal rate was reached to maximum state by supplementing 1200 ppm FeSO$_{4}$ and pH 9.5.
