In the beaker of the test C source categories, the proportion of different C sources, C / N, C / P ratio on denitrifying phosphorus microorganisms. Experiments show that the different effects of C source anoxic phosphorus uptake is the order of sodium acetate, propionate, glucose, phosphorus denitrifying bacteria on C / N, C / P, or more stringent requirements, C / N, C / P too high or too low will affect the experimental results.
