[Inhibition of Internal Phosphorus Release in the Black-Odor Channel Under Different Adding Methods of CaO].

The inhibition of sedimentary phosphorus(P) was investigated under the CaO with 3 addition ways. The overlying water and sediments came from a black-odor channel in S City. The results showed that the value of pH and DO in the overlying water increased under the 3 addition ways of CaO.
