Method for relieving inhibition of nano-zinc oxide on activity of aerobic granular sludge

The invention discloses a method for relieving activity inhibition of nano zinc oxide on aerobic granular sludge, which comprises the following specific steps: 1) adding aerobic granular sludge into a sequencing batch reactor, and taking synthetic wastewater as a substrate of the sequencing batch reactor; 2) adjusting the sludge concentration in the reactor to 2g VSS L ; 3) after the reactor stably runs, adding two nano materials; (4) under the conditions that the temperature is 25 +/-1 DEG C and the pH value is 7.8 +/-0.5, operating for six hours in an A/O/A mode; and (5) extracting supernate, and detecting various water quality indexes. By researching the influence of the nano pollutants on the activity inhibition of the aerobic granular sludge under single stress and composite stress, the method is closer to the actual situation of a sewage treatment plant, and a new thought and method are provided for promoting the wide application of the aerobic granular sludge. 本发明公开了一种缓解纳米氧化锌对好氧颗粒污泥活性抑制的方法，该方法的具体步
