Sewage treatment facility that can separate and treat struvite stones

摘要

The present invention reduces the scale formed in pipes, concentrators, dehydrators, etc. in the subsequent treatment process by calcifying and separating magnesium, ammonium, and phosphorus materials to remove excess phosphorus from sewage treatment facilities. It relates to a sewage treatment plant that can separate and treat the stones that can be used as fertilizers, while extending the lifespan and reducing maintenance costs. To this end, the sewage treatment facility capable of separating and treating stones according to an embodiment of the present invention includes a treatment tank that treats sewage to be purified when it flows in, and a settling basin provided together with the treatment tank to precipitate sediment from the sewage and separate it. , an anaerobic tank provided at the back of the treatment tank and the settling tank to reduce the concentration of pollutants by contacting domestic sewage with anaerobic bacteria that decompose high-concentration organic matter under anoxic conditions; Symbol water is introduced from the dehydrator and the anaerobic tank that separates the water, and the desorption filtrate is introduced from the dehydrator, and magnesium, ammonium, and phosphorus substances are crystallized and separated from the sewage through a reaction by contacting the symbol water and the desorption filtrate and adjusting the pH concentration. Includes generator.
