System and method treating sewage and wastewater to recover biosolids and phosphorus |
| abstract |
The present invention relates to a sewage/wastewater treatment facility capable of recovering biosolids. In the present invention, a phosphorus crystallization device for recovering phosphorus crystals from an anaerobic digestion liquid flowing from an anaerobic digester, and a liquid cyclone that separates only the phosphorus crystals after receiving the contents including phosphorus crystals stored in the phosphorus crystallization device and then flows back into the phosphorus crystallization device. Disclosed is a sewage/wastewater treatment facility capable of recovering a biosolid containing it. In the present invention, by using a phosphorus crystallization apparatus in combination with a liquid cyclone, phosphorus crystals having a diameter of several tens of micrometers are not recovered, but can be recovered after growing from several hundred micrometers to several millimeters in diameter through the liquid cyclone. |
