Abstract:
Ocean sludge exerts a very big environmental load to local sea area.
Here, attention was paid to micro-bubble technology for application to
the purification of the sludge. The important point in this technique is to
activate the bacteria existing in the area by micro-bubbles. We had
developed a method for decomposing the sludge by using of
microorganisms in an aerobic state by micro-bubble. We had very good
results by the method, and also understood that hydrogen sulfide is
reduced at first and then the nutrients will be reduced. Here, we have also
a technique for purification by using “coagulants”. Therefore, we
proposed the experimental way which hydrogen sulfide is reduced at first
by using “coagulants” and then the nutrients will be reduced by microbubble
and activating microorganisms. Here, we used the detergents
including enzyme as the microorganism activator. Our research object in
this paper is to check the purification performance for sludge by our
proposed experimental way. From the results of our experiments, we
succeeded in reducing the time needed to purify the sludge, and we
obtained the very good performance.
