| 摘要 |
The present invention relates to a separation apparatus for processing wastewater including domestic sewage or effluent, or water requiring dissolved oxygen, which comprises a wastewater tank (10) accommodating wastewater and having a contracted pipe portion (12) in the upper part of the body; a processed water collecting pipe (20) mounted in the center of the wastewater tank (10) and discharging the processed water in which foreign substances included in the wastewater have been filtered through a processed water passage pipe (22); a sludge tank (30) mounted on the upper side of the wastewater tank (10), accommodating the foreign substances included in the wastewater which has been collected through the contracted pipe portion (12), and discharging to a processing place; and an injection device (40) mounted on the wastewater tank (10) with a slope, spraying air or micro bubbles toward the wall of the processed water collecting pipe (20) and generating the centrifugal force. The separation apparatus according to the present invention processes the foreign substances by selectively operating the air generator and the bubble generator upon the concentration of the wastewater, and enables to process wastewater at a low concentration as well as water requiring dissolved oxygen, which maximizes the user satisfaction. |
