Embodiment Construction
[0035]The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0036] Step 1: Screening and cultivation of bacterial flora
[0037] a. UASB cultivation and domestication (6-7): Inoculate anammox flocculent sludge (6) in UASB, use ammonium bicarbonate and sodium nitrite as nitrogen sources under anaerobic conditions, and control influent NH 4 + and NO 2 - The concentration of the concentration is gradually increased from 50mg / L and 65mg / L to 60mg / L and 80mg / L, and trace elements (CaCl 2 2H 2 O 36mg / L, MgCl 2 ·6H 2 O 40mg / L, ZnSO 4 ·7H 2 O0.215mg / L, NiCl 2 ·6H 2 O 0.095mg / L, NaSeO 4 10H 2 O 0.21mg / L, MnCl 2 4H2O 0.495mg / L, C 10 h 16 N 2 o 8 8.304 mg / L, H 3 BO 3 0.007mg / L, CuSO 4 ·5H 2 O 0.125mg / L, CoCL 2 ·6H 2 O 0.12mg / L, NaMO 4 2H 2 O 0.11mg / L, FeSO 4 ·7H 2 O 5mg / L) to meet the growth needs of microorganisms, control the temperature in the UASB to be 32~36°C, and continuously o...
