%X The electron acceptor-nitrite can become inhibitory or toxic towards the denitrifying phosphorus removal process. To study the inhibitory effect of nitrite during the anoxic phase of denitrifying phosphorus removal, jar tests were conducted with nitrite as the electron acceptor. The results indicated that more than 30 mg·L-1 nitrite will severely inhibit anoxic phosphate uptake, but the threshold inhibitory concentration was dependent on the characteristics of the activated sludge and the operating conditions. Exposure to less than the inhibitory concentration was not detrimental to anoxic phosphorus uptake, rather nitrite as well as nitrate replaced oxygen as the electron acceptors, and had a positive effect on denitrifying biological phosphorus removal.
