求翻译：在第55天，添加磁粉反应器的CODCr去除率达到85%左右，之后将废水进水CODCr浓度提高至设定浓度1120mg/L，在微生物适应之后，CODCr去除率趋于稳定，达到90%左右，而无磁粉反应器的CODCr去除率仅在60%左右。是什么意思？

On the 55th day, added magnetic reactor CODCr removal rates reached about 85%, increasing the inlet concentration of CODCr of wastewater to set concentration after 1120mg/L, after the microbial adaptation, CODCr removal rates stabilized, around 90% and CODCr removal rate is only for non-power reactor at around 60%.
