The Development of Treatment System for Removing the Low Concentrated Nitrogen and Phosphorus Using Phototrophic Bacteria and Media

摘要: We used phototrophic bacteria to remove low concentrated organic materials (CODCr), nitrogen and phosphorus. applied 37.3 mg/L, 4.0 1.0 mg/L (C:N:P=100:10:1) in the batch test, removal efficiencies were shown as follow: 87.4%, 46.3%, 79.7%. The aerobic process with mixed bacteria, ceramic media, media KSP01 showed of , each 72.7% 79.2%, respectively lab-scale reactor. maximum efficiency reached 92.6% by adjusting pH. There three conditions . highest was 98.5% 10.2 L/min aeration 1-2 reactors, result applying river-water high (82.8%). Therefore, this purification system may be useful control phosphorus at concentration field.
