SYSTEM FOR TREATING TOTAL PHOSPHORUS FROM EFFLUENT WATER OF SEWAGE TREATMENTPLANT DURING THE DRY SEASON AND TREATING STORM WATER RUNOFF SELECTIVELY DURING RAINY DAY

摘要

PURPOSE: A selective processing system of rain fall effluent during the raining season and sewage disposal plant effluent during the dry season is provided to actively perform a stirring process using an inline mixer. CONSTITUTION: A selective processing system of rain fall effluent during the raining season and sewage disposal plant effluent during the dry season comprises a biological wastewater treatment device, a high speed stirrer, a slow speed stirrer(2), a cohering treatment device, a first settling pond, and a sludge-increased cohesion agent separator. The high speed stirrer mixes a cohesion agent with object water to be treated. The slow speed stirrer forms huge flocks by slowly stirring the object water.
