| Abstract |
The biological nutrient removal from wastewater with low C/N and C/P is difficult. This study was carried to remove nitrogen and phosphorus from wastewater by using the 5-stage BNR process with denitrifying phosphorus removing bacteria(DPB). The 5-stage BNR process could achieve stable phosphorus and nitrogen removal with less substrate consumed. These laboratory experiments revealed that step feed with DPB showed a possibility of biological nitrogen and phosphorus removal from low organic municipal wastewater. With DPB, specific denitrification rate was 1.3 ㎎NO₃-N/gVSS/hr and specific phosphorus utilizing rate was 2.0 ㎎SP/gVSS/hr. |
