According to the high concentrations of industrial wastewater in chemical industrial park，through the analysis of
problems existing in original ordinary A2
/O process，the improved A2
/O ditch process was put forward． The transformation
operation results showed that the removal rate of COD NH3 －N TP was 57. 26% 76. 94% and 98. 36% respectively; and
indexes of the effluent by the biochemical system achieved the first level standard : Integrated Wastewater Discharge
Standard ( GB 8978 1996) ．
