| Abstract |
A study was conducted to investigate the behavior of phosphorus forms at each stage in the sewage treatment processes. The total phosphorus concentration of the domestic wastewater in the sewage plant was 3.5㎎/ℓ and distribution of total reactive phosphorus (TRP), total acid-hydrolyzable phosphorus(THP) and total organic phosphorus(TOP) in the T P concentration was about 42%, 25% and 33%, respectively. The T-P concentration in the grit chamber was about 8 times higher than that in domestic wastewater, under the influence of inflowing thickner and digester supernatant. The removal ratios of THP and TOP at sewage plant were about 65%, 75%, respectively. It was found that the removed phosphorus forms were mostly SHP and SOP, but TRP was not removed at ail. The amount of T-P flowed into the sewage plant was 51.7㎏/10,000㎥/day, that removed by the sewage treatment processes was 23.0㎏/10,000㎥/day that loaded to lake was 28.7㎏/ 10,000㎥/day. |
