- Abstract:
- Effects of adding Bacillus at different locations in a black and odorous river on sediment degradation were investigated. Bacillus was added to the sediment, sediment-water interface and overlying water, respectively, and corresponding indexes were determined and analyzed. Adding Bacillus at different locations all had remediation effects on black and odorous river. The best remediation performance was achieved when Bacillus was added to the sediment-water interface, the removal efficiencies of NH3-N, TN, TP and COD in the water were 63.65%, 42.71%, 39.14% and 63.13%, respectively, and the removal efficiencies of NH3-N, TN, TP and organic matter in the sediment were 59.88%, 65.99%, 59.07% and 57.07%, respectively. The color of the sediment changed from black to yellow, its thickness decreased by 18%, and its biodegradability also increased.
