The total nitrogen in tannery wastewater was treated by prepared bioflocculant at different conditions. The most suitable conditions for total nitrogen removal was attained at a normal temperature, pH of 8, flocculant of 1.0 g/L when the shaking speed was 200 r/min and the reaction time was 30 min. Through testing saccharide and protein in the bioflocculant, it was found that the bioflocculant contained saccharides and proteins. After detecting the content of saccharide and protein before and after reacted, it was found that the content of saccharides and proteins in the bioflocculant decreased after treating total nitrogen which meant the saccharides and the proteins in the bioflocculant played flocculation effect in the removal of total nitrogen from tannery wastewater, and the saccharides played main effect. It is expected that the results will contribute to the industry treatment of total nitrogen removal in tannery effluent by bioflocculant.
