Abstract： |
The invention discloses an ecological denitrify technology of photosynthetic carbon-supplying, which is characterized by the following: inputting the disposed water into underflow wetland; making water pass algae growing pool of aerating plant into sedimenting pool; refluxing mud to first-segment underflow wetland; flowing water from sedimenting pool to next-grade underflow wetland; flowing out of disposing system after sanitizing; utilizing natural attribute of algae photosynthesis completely to fix carbon in the air; supplying the needed carbon source in the denitrifying course through plant and algae metabolism product and living body degraded product; recycling carbon without secondary pollution; possessing negative feedback function and good stability; making urban effluent reach surface-water III standard. |
