求翻译：原制药废水可生化性差，采用好氧生物膜法无法直接进行处理。经铁炭微电解预处理后，原水的可生化性得到提高，经驯化后的好氧生物膜降解铁炭微电解废水，CODcr去除率可以达到63%是什么意思？

The original pharmaceutical wastewater biodegradability, the use of aerobic biofilm can not be directly processed. After the iron-carbon micro-electrolysis pretreatment of raw water biodegradability increased degradation of iron-carbon micro-electrolysis wastewater by aerobic biofilm domestication c

The original pharmaceutical waste water can be a chemical or biological, aerobic biological membrane cannot be directly for processing. The charcoal iron micro-electrolyte pre-processing, the raw water can be chemical or biological, have been improved, after the domestication of the aerobic biologic

The original drugs manufacture waste water may the biochemistry difference, use the oxygen biology membrane method to be unable to carry on processing directly.After the hard coal micro electrolysis pretreatment, the original water may the biochemistry obtain the enhancement, after the domesticated

The original poor biodegradability of wastewater, the use of aerobic biofilm does not directly handle. After by ferric-carbon micro-electrolysis pretreatment, improved biodegradability of raw water, the domestication of aerobic biofilm wastewater degradation of iron-carbon micro-electrolysis and COD
