영어 초록
A long- time aeration method was developed for purification of animal wastewater. Under repeated aereations of 4 hours on and 4 hours off, the higher removal rates were obtained which were in average of 99%, 96%, 92% and 50% for BOD, SS, total nitrogen and phosporous, respectively. In detail, the measured BOD concentrations of the influent and effluent were 2,700ppm and 40ppm while the SS concentrations in the primary chamber and of the effluent were about 3,000 and 110 ppm, respectively. Zeolite and activated carbon, applied for removing the nitrogen and phosphorous, showed a good absorption, especially zeolite for NH4-N and activated carbon for NO3-N and PO4-P. The treatment cost per head by this method amounts to 1,923 won and it comes to 1.6% in the whole production cost. Therefore, this method is economically available with the half cost of the conventional activated sludge process.
