| 摘要 |
The present invention relates to a contact-abandoned sewage treatment method and a contact-abandoned sewage treatment apparatus using the same. Of raw water introduced into a water level adjustment tank, high-concentration sewage is transferred to an anaerobic part through a second raw water transferring pipe provided in a first water level adjustment tank, whereas low-concentration sewage is transferred to an aerobic part through a first raw water transferring pipe provided in a second water level adjustment tank, bringing an increase in efficiency of the high-level treatment by increasing the C/P and C/N ratio in a property-conversion aerobic tank. |
