Abstract
Disclosed are a wastewater filtering method and apparatus comprising filter media of different sizes. According to one aspect of the present embodiment, provided a wastewater filtering method and apparatus capable of stable and efficient operation by minimizing the head loss as well as simultaneously removing organic matter and solids in a large flow of wastewater.
Claims8
A filtration device for treating wastewater, the device comprising:
- a distribution channel for distributing a wastewater vertically upward or discharging backwash water, received vertically downward, to the outside;
- filter media for raising due to a lower specific gravity than water when the wastewater is distributed vertically upward from the distribution channel to filter solids and organics in the wastewater and descending when the backwash water flows in vertically downward to remove the attached solids and organics;
- and
- a treated water storage tank for receiving the treated water from which solids and organics are removed through the filter media and discharging it to the outside or discharging the backwash water flowing in from the outside to the filter media.
1 more element
A filtration method of wastewater by a wastewater filtration device, the method comprising:
- a distribution process for distributing the incoming wastewater vertically upwards;
- a first filtration process for filtering solids in the distributed wastewater;
- a second filtration process for filtering fine solids and organics from wastewater from which solids are filtered;
- a discharge process for storing each component-filtered treatment water or discharging it to the outside;
- and
- a spraying process for spraying backwash water vertically downwards.
