With the method of Enrichment→Separation→Filter→Activation, isolated and purified from the activated sludge receive two high flocculating activity of the flocculant-producing bacteria, like LBw5, LBw20. Researching into the growth of LBw5 strains at different incubation time, pH values; distribution of flocculating activity and the impact on the flocculation rate of Metal ions, kaolin concentration, dosage, etc. The result has showed that the amount of flocculating activity is positively correlated to bacterial growth.. Otherwise, this flocculant-producing bacteria has a high flocculating activity and stability on kaolin suspension. The best medium for the flocculant-producing bacteria LBw5 is LB medium; the best culture conditions for flocculant-producing bacteria LBw5 is as follows, the initial pH is 6.5-8.5, the culture temperature is 30℃, the culture time is 72 h, and the ventilation is 150 r/min. The research also shows that, the most suitable pH of the flocculant-producing bacteria LBw5 flocculating kaolin suspension must in the alkaline conditions more than 7. Metal ions have a promoting effect on its flocculation, like Ca2+, Mg2+, Al3+ and so on, flocculation rate may up to 79.2%.

正确答案：

"The activity studying result indicates a flocculation, and bacterium growth passing to LBw5 bacterial strain in the field of change condition and flocculation activity being unlike the value training the time growth condition , training liquid a pH etc. amounts Cheng Zheng relevance " The method "using beneficiation- separation- preparation by screening- to activate two is had flocculant more active than high flocculation producing bacterium LBw5 , LBw20 from separating a purification in activity sludge. Go into passing to LBw5 bacterial strain in the field of change condition and flocculation activity being unlike the value training the time growth condition , training liquid a pH etc., result indicates flocculation activity and amounts bacterium growth Cheng Zheng are related to. And owe the flocculant that the bacterium produces the flocculation activity and stability that turbid liquid has to kaolin comparatively highly; LBw5 bacterial strain produces optimum flocculant culture medium being check culture medium; The best of LBw5 bacterium product flocculant trains condition By : 8.5, cultivates initial pH value for 6.5 ~ temperature 30 ~C, r/min cultivating time in order 72 hs , breathable amounts are 150. The most proper turbid liquid pH is in what LBw5 bacterial strain produces flocculant flocculation kaolin greater than 7's slanting basicity the ion has metal such as Ca2 + , Mg2 + and Al3 + to it's flocculation under condition, boosting the effect , flocculation rates may amount to 79.2%.

With enrichment - Separation - Filter - Activation method from activated sludge purified from two high flocculating activity of the flocculant-producing bacteria LBw5, LBw20. By LBw5 strains at different growth of the culture time, medium pH, changes in circumstances and flocculating activity of the research results show that the amount of flocculation activity and bacterial growth is positively correlated. And the flocculant produced by bacteria in suspension of kaolin has a high flocculating activity and stability; LBw5 flocculant producing strains of the best medium for Cha's medium; LBw5 flocculant producing bacteria optimal culture conditions as follows: The initial pH value of 6.5 ~ 8.5, temperature 30 ℃, culture time 72 h, ventilation capacity of 150 r / min. LBw5 flocculant strain produced by the most appropriate flocculation kaolin Suspension pH greater than 7 is alkaline conditions, Ca2 +, Mg2 + and Al3 + and other metal ions on the flocculation of a catalytic role in flocculation rate of up to 79.2%

Use enrichment - separation method of screening - activate - from activated sludge separation and purification of two strains with high flocculation activity of flocculant LBw5 bacteria produce, LBw20. Based on LBw5 strains in different time of growth, medium pH change and flocculation activity, etc, the results show that the research activities and flocculation bacteria growth into positive correlation. And this bacterium of flocculant on high alcohols kaolin flocculation activity and stability, LBw5 strains of flocculant best medium for check's medium, LBw5 bacteria produce flocculant best condition for: initial pH value of 6.5 ~ 15%, temperature, time is 30 degrees c h, ventilation, 72 for 150 r/min. LBw5 strains in the flocculant flocculation kaolin the optimal pH alcohols in more than 7 slant Ca2 + alkaline conditions, Mg2 Al3 + + and, on such metal ions can promote its flocculation, flocculation 79.2% rate.

By LBw5 strains at different growth of the culture time, medium pH, changes in circumstances and flocculating activity of the research results show that the amount of flocculation activity and bacterial growth was positively related to" The best translation of the whole paragraph, as follows "Using enrichment - Separation - Filter - Activation method from activated sludge purified from two high flocculating activity of the flocculant-producing bacteria LBw5, LBw20. By LBw5 strains at different incubation time the growth, culture medium changes in pH, and the flocculating activity of the research results show that the flocculating activity and the amount of bacteria growth is positively correlated. flocculant produced by bacteria, and Suspension of the kaolin has a high flocculating activity and stability; LBw5 strains producing flocculation The best medium for investigation agent's medium; LBw5 the best flocculant producing bacteria culture conditions as follows: initial pH value of 6.5 ~ 8.5, temperature 30 ℃, culture time 72 h, ventilation capacity of 150 r / min. LBw5 flocculant strain produced by the most appropriate flocculation kaolin Suspension pH greater than 7 is alkaline conditions, Ca2 +, Mg2 + and Al3 + and other metal ions on the flocculation of a catalytic role in flocculation rate of up to 79.2%.
