This application relates to the field of wastewater treatment technology, specifically providing a method and system for the synergistic oxidation-reduction coupling treatment of ethylthionitrogen-C-N-S in mineral processing wastewater using a MABR oxygen stratification process. This method and system innovatively develops a time-sequential dissolved oxygen (DO) dynamic control strategy: by periodically / pulsally switching anaerobic-hypoxic-aerobic conditions, the oxidation and ammonification reactions of ethylthionitrogen are directionally enhanced, and the toxic inhibitory effects of intermediate products on functional bacteria are eliminated. Based on this strategy, the system can precisely utilize the spatial distribution of the biofilm oxygen gradient within a single MABR reactor to achieve a cascade reaction of ethylthionitrogen: "sulfur oxidation-ammonification → aerobic nitrification → anoxic denitrification"; or, for high-concentration ethylthionitrogen (>50 mg / L), it can couple a pre-anaerobic reactor to enhance ammonification detoxification and denitrification.

The invention provides a preparation method of oil-absorbing moisture-absorbing anti-skid sawdust applied to a kitchen waste machine, which comprises the following steps: crushing wood in a crusher to obtain sawdust, drying the sawdust in a dryer at low temperature to obtain dried sawdust, cooling the dried sawdust, putting the cooled sawdust in a stirrer, adding compound bacterial sludge, and stirring to obtain the oil-absorbing moisture-absorbing anti-skid sawdust. And starting the stirrer to fully mix the sawdust and the composite bacterial sludge to obtain the composite sawdust. Firstly, the prepared composite sawdust is put into a kitchen waste machine, then the kitchen waste is put into the kitchen waste machine, the kitchen waste machine is started for crushing, sewage and oil water seeping in the crushing process are absorbed by the composite sawdust, the sewage and the oil water are decomposed and degraded by the composite bacterial sludge in the composite sawdust, the situation that the environment is polluted when the kitchen waste serves as waste is prevented, and the environmental protection performance is improved.
