| Abstract |
In this research, we investigated the possibility of applying biosorption reaction to the advanced wastewater system with the analysis of the various operating conditions using the contact stabilization system. Biosorption is common reaction that makes biological removal, adsorption and coagulation achieved using the MLSS in the endogenous respiration. In the paper, we researched the influence of operating conditions, such as MLSS. adsorption time, DO, and activity of microorganism etc. in the biosorption reaction. And it was calculated the mass-balance lor the quantity analysis. The results were abtained as follows: 1. The optimal biosorption condition were determined adsorption time 15min, MLSS 2200㎎/L. DO 0.2㎎/L. Under this optimal condition, the carbon adsorption ratio was 65.5% and the total removal ratio was 81%. 2. The T-N. T-P adsorption ratio is 25.3%, 50.8% respectively under the optimal biosorption condition 3. The adsorption velocity is expressed as the Freundlich isotherm : COD_(ad)/MLSS=19.44(COD_(ex))^(0537). 4. In the optimal biosorption condition, the BOD_(5) amounts are 12.5g/day, which are able to remove the 3.7gNO₃-N/day. |
