求翻译：由于接种的污泥活性较低，且大部分微生物为厌氧菌，因此需要对污泥进行驯化。将污泥连接到曝气装置，控制曝气量，提高微生物活性。加入分别以葡萄糖、硫酸铵、磷酸二氢钾作为碳源、氮源和磷源的人工模拟废水，由低到高逐渐增加废水浓度，使接种污泥逐渐适应较高CODCr浓度的废水，此过程需要3周的时间完成。是什么意思？

Lower due to inoculation of activated sludge, and most micro-organisms for anaerobic bacteria, hence the need for sludge acclimation. To connect the sludge aeration device, control of the aeration, improving microbial activity. Adding potassium dihydrogen phosphate by glucose, ammonium sulfate, respectively as a carbon source and nitrogen source and artificial simulation of wastewater phosphorus sources, increases gradually from low to high concentration wastewater, making vaccination gradually adapt to the higher concentration of CODCr of wastewater sludge, this process can take 3 weeks to complete.
