Method for acclimating activated sludge by using glucose as co-substrate and application of acclimatedactivated sludge in deep treatment of coking wastewater

The invention relates to a method for acclimating of activated sludge capable of deeply treating coking wastewater by taking glucose as a co-substrate. The method comprises the following steps: taking activated sludge and aerating the activated sludge to recover the activity of the activated sludge; adding a microbial growth substrate into a reactor by adopting an SBR process, adding coking wastewater according to the proportion of 10% of the effective volume of the reactor, and supplementing deionized water into the remaining space, wherein the retention time of each gradient is 12 days, every 72 hours is an operation cycle, the DO of the SBR is controlled to be 3.0 +/-0.5 mg/L, the water temperature is 20.1-21.5 DEG C, the pH value is 8.45-8.86, the sludge age is 25-30 days, and the drainage ratio of each cycle is 60%; and after the concentration of mixed liquor suspended solids reaches 3500 +/-150 mg/L, the sludge settling ratio of the mixed liquor being 15-20%, then, increasing the dosage of the coking wa
