specific Embodiment approach 1
[0014] Specific embodiment one: the bioaugmentation treatment method of polyacrylamide-containing sewage in this embodiment is realized according to the following steps: one, get the activated sludge of domestic sewage plant, add in the SBR reactor, the sludge concentration is 2000mg / L, The influent is domestic sewage, add PAM concentration to 20mg / L, and COD is 200-300mg / L; 2. Every time the SBR reactor runs for a cycle, the PAM concentration is increased by 20mg / L until it rises to 100mg / L, and continues to run for 20 Days to complete domestication; 3. According to 1×10 8 per L reaction volume, add HWBI into the domesticated SBR reactor, when the dissolved oxygen concentration is 2-3mg / L, the pH value is 6.5-8.0, the PAM concentration is 100-150mg / L, and the sludge concentration is After 45 days of operation under the condition of 1500~2000mg / L, the bioaugmentation treatment of polyacrylamide-containing sewage is completed; the operating conditions of each cycle of SBR react...
specific Embodiment approach 2
[0018] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that enrichment culture needs to be carried out before adding HWBI in step 3. The enrichment medium used is dissolved in 1g of beef extract, 10g of peptone and 5g of NaCl. Composed of 1000mL distilled water, pH value is 7.2~7.4. Other steps and parameters are the same as those in Embodiment 1.
specific Embodiment approach 3
[0019] Specific embodiment three: the difference between this embodiment and specific embodiment one is that in step three, the dissolved oxygen concentration is 2.5 mg / L, the pH value is 7.0, the PAM concentration is 120 mg / L, and the sludge concentration is 1800 mg / L. Down run for 45 days. Other steps and parameters are the same as those in Embodiment 1.
