A WATER TREATMENT SYSTEM AND A METHOD OF CLEANING CONTAMINATED WATER

摘要

A water treatment system (1) for cleaning contaminated water comprises a channel (2) through which water can flow. The channel (2) is provided with a mixing device (9) and a reaction zone (10) located downstream of the mixing device (9). The water can flow substantially undisturbedly through the reaction zone (10). An ozone injector (12) is located upstream of the mixing device (9) and a hydrogen peroxide injector (13) is located upstream of the ozone injector (12). The channel (2) has a vertically oriented channel portion (3) including a reactor pipe (5), an inlet pipe (4) located upstream of the reactor pipe (5) and an outlet pipe (6) located downstream of the reactor pipe (5) and above the inlet pipe (4). The reactor pipe (5) has a larger cross-sectional flow area than each of the inlet and outlet pipes (4, 6). The mixing device (9) and the reaction zone (10) are located within the reactor pipe (5), whereas the ozone injector (12) and hydrogen peroxide injector (13) are located upstream of the reactor pipe (5).
