The utility model discloses an accurate adding system for supplying carbon source for biomass in a biological sand filter, which is characterized in that a sand layer (2) is arranged in the biological sand filter (1), a monitor sampling point (3) is arranged in the sand layer (2), a carbon source releasing tank (7) is connected with the sand layer (2) through a carbon source adding pipeline, a signal output end of the monitor sampling point (3) is connected with a data collection module (9), signals of the data collection module (9) are respectively connected with a movement module (8) and a central control single chip microcomputer (10). The accurate adding system uses plant rot media as external adding carbon source to denitrify, thereby being low in cost, full in source, low in operation cost, and capable of avoiding high cost of general carbon source and greatly reducing cost of carbon source. Simultaneously, online monitor equipment is used to control outlet water quality in real-time mode, thereby savin
