[0038] 1) Startup steps
[0039] First start the reactor, the inoculum of the SNAP reactor adopts the bacterial sludge enriched by the SNAP reactor cultivated in this laboratory and operated for more than one year, the MLSS is 10.1 g / L, the MLSS is 12.5 g / L, and the sludge color It is reddish brown. by NaHCO 3 As a pH regulator, ensure that the pH of the reactor is maintained at about 7.5-7.8, and the temperature of the reactor is controlled at 33-35°C. The nutrient solution matrix KH added in the experiment 2 PO 4 136 g / L, trace element I is FeSO 4 18 g / L and EDTA 10 g / L, mineral elements KCl1.4 g / L, NaCl 1 g / L, MgSO 4 1 g / L, CaCl 2 1.4 g / L, trace element II is MnCl 2 4H 2 O 9.9 mg / L, NiCl 2 ·6H 2 O 1.9 mg / L, Na 2 MoO 4 2H 2 O 2.2 mg / L, ZnSO 4 ·7H 2 O 4.3 mg / L, CaCl 2 ·6H 2 O 12mg / L, CuSO 4 ·5H 2 O 12.5 mg / L, H 3 BO 4 0.14 mg / L. In the process of water distribution, 0.5 ml of substrate, 0.5 ml of trace element I, 0.1 ml of trace element II, and 1 ml...
