| 摘 要： | 挥发性脂肪酸（ＶＦＡ）是消化污泥上清液（ＤＳＳ）中主要的组分。ＤＳＳ是反硝化很好的碳源。在本试验条件下，ＤＳＳ碳源完全反硝化的临界值为１．７４ｍｇ ＤＳＳ－Ｃ／ｍｇＮＯ３－Ｎ。但是，ＤＳＳ中的ＴＫＮ除了很小一部分被用于同化合成外，其大部分进入反硝化系统后不发生任何变化并出水排放。

| Abstract: | Volatile fatty acids (VFA) are main constituents of di- gested sludge supernatant (DSS) and DSS is a good carbon source for denitrification. Under test condition, the critical value of DSS for complete denitrification was 1.74mgDSS-C/mg NO3--N, but TKN in DSS could introduce into denitrification system except a small portion was consumed as assimilatory synthesis. |
