求翻译：由于接种的厌氧污泥进入微氧环境，对CODCr负荷的抗冲击能力较差，因此先对其进行驯化。实验组反应器加入4g/L的磁粉，对照组不加磁粉。在初始阶段，采用较低浓度的模拟废水，并在曝气槽中增加曝气量，使溶解氧控制在1.0mg/L以内。运行5天后，污泥颜色逐渐变浅，由深黑色变成褐色，说明污泥由完全厌氧转变成微好氧。从第6天开始，逐渐增加废水浓度，在整个运行当中，pH保持在6.5-8之间，直到葡萄糖浓度在第50天达到1600mg/L，反应器运行正常，使污泥的驯化和培养同时进行。是什么意思？

Due to the vaccination of anaerobic sludge into micro-oxygen environment, poor to shocks to the CODCr load, so its first domestication. Experimental reactor joined the Group 4g/L of magnetic particles, control group without magnetic powder. In the initial stages, with a lower concentration of wastewater, and increasing the aeration in the aeration tank, dissolved oxygen control in less than 1.0mg/L. After running for 5 days, sludge gradually lightens the color from black into Brown, notes by completely anaerobic sludge into micro-aerobic. From the beginning of the 6th day, gradually increase the concentration of wastewater, throughout the operation, pH maintained between 6.5-8, until the concentration of glucose on the 50th day reached 1600mg/L, reactor is operating normally, domestication and cultivation of sludge at the same time.
