| 摘要 |
The present invention relates to a system to which a wastewater treatment method for sludge reduction is applied and, more particularly, to a system to which a wastewater treatment method for sludge reduction is applied so that chemical and mechanical excess sludge pre-treatment resulting in an increase in sludge solubility and biodegradability is performed for sludge reduction. According to the present invention, excess sludge is drawn from a membrane separation-type active sludge treatment device and pre-treated for solubility and biodegradability enhancement. Then, transport toward the membrane separation-type active sludge treatment device or an anoxic tank is performed for a significant reduction in sludge treatment amount. Accordingly, treatment costs can be reduced to a significant extent. In addition, nitrogen removal efficiency can be enhanced by an additional carbon source required for nitrogen removal being supplied. Furthermore, the present invention has a high level of phosphorus removal efficiency. |
