Title:
ENERGY-SAVING NATURAL DOWNFLOW TYPE OF CLEAN-WATER AND SEWAGE/WASTEWATER TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/139089
Kind Code:
A2
Abstract:
The present invention relates to a mixing device (rapid mixing equipment), a flocculation basin and a hybrid filter basin (hybrid filter) for wastewater treatment to obtain clean water. A coagulant is introduced into a mixing device containing waste water for treatment, to isolate colloidal fine particles, dissolved pollutants and phosphorus. The wastewater and introduced coagulant are rapidly mixed in a state of natural down-flow. In the flocculation basin, the sediment or fine floc generated in the mixing process are made to effectively collide in a state of natural down-flow and are thereby formed into a larger floc that is easy to sediment out. In the hybrid filter basin, the larger floc is removed by sedimentation and filtering, thereby achieving treated water target quality.
