Example Embodiment
[0021] Example 1 The flocculating microbial strain A was isolated and screened from the soil of the brewery plant, and 0.5% strain A seed suspension was inoculated into the saccharification workshop wastewater with 0.05% residual sugar after autoclaving, and aeration cultured at 27°C for 48 Hours, the fermentation broth is the flocculant, and the flocculation rate of the flocculant to the kaolin suspension is about 95%. Take 5ml of the flocculant and add it to the 100ml of concentrated sludge in the second settling tank of the brewery sewage treatment workshop. After mixing evenly, flocculation and coagulation will appear. After natural standing and settling for 20 minutes, a clear solid-liquid boundary will appear, indicating that the flocculation dehydration effect is good .
Example Embodiment
[0022] Example 2 The flocculating microbial strain B was separated and screened from the activated sludge of the brewery, inoculated with 2.0% strain B seed suspension into the saccharification workshop wastewater with a residual sugar of 0.05% and pH 6.8, and aerated culture at 35°C 36 Hours, the fermentation broth is the flocculant, and the flocculation rate of the flocculant to the kaolin suspension is about 98%. Take the flocculant 3ml, 1% CaCI 2 2ml was added to 100ml of concentrated sludge in the second settling tank of the brewery sewage treatment workshop. After being evenly mixed, flocculation and coagulation occurred. After natural standing and settling for 20 minutes, a clear solid-liquid boundary appeared, indicating that the flocculation and dehydration effect was good.
Example Embodiment
[0023] Example 3 The flocculating microbial strain C was isolated and screened from the brewery wastewater, inoculated with 1.0% strain C seed suspension into the autoclaved COD: 3000 mg / L, pH 7.0 beer wastewater, and aerated at 35°C After 60 hours of cultivation, the fermentation broth is the flocculant, and the flocculation rate of the kaolin suspension by the flocculant is about 97%. Take the flocculant 3ml, 1% CaCI 2 1ml was added to 100ml of concentrated sludge in the secondary sedimentation tank of the brewery sewage treatment workshop, and flocculation appeared after the mixture was evenly mixed. After standing for 20 minutes, a clear solid-liquid boundary appeared, indicating that the flocculation and dehydration effect was good.
