AOB, NOB, and DB represent ammonia-oxidizing bacteria, nitrite-oxidizing bacteria, and denitrifying bacteria. NTU, WT, ORP, DO, TN, NH4+-N, NO3–-N, TP, PO43−-P, NO2–-N, CHl, SOD, and MDA represent turbidity, water temperature, redox potential, dissolved oxygen, total nitrogen, ammonia nitrogen, nitrate nitrogen, total phosphorus, phosphate, nitrite nitrogen, chlorophyll, activity of superoxide dismutase, and content of malondialdehyde respectively.
