The invention belongs to the technical field of
environmental engineering, and discloses a method for improving residual
sludge microbial fuel cell biological power generation and
sludge stabilization through pre-chlorination, and the method comprises the following steps: adding
sodium hypochlorite into residual
sludge, and uniformly mixing, so as to pre-chloridize the residual sludge; and then, adding the pre-chlorinated excess sludge into the sludge
microbial fuel cell subjected to microbial acclimation, and continuously operating the sludge
microbial fuel cell. According to the method disclosed by the invention, the residual sludge is pre-chlorinated by using the
sodium hypochlorite, and the concentration of the
sodium hypochlorite in the pre-chlorinated residual sludge is strictly controlled to be 0.2 mg / L, so that
resource utilization and sludge stabilization of the residual sludge can be realized at normal temperature based on a microbial fuel
cell technology. Through the sludge pre-chlorination means, the performance of the microbial fuel
cell can be improved, and especially the biological power generation and sludge stabilization efficiency of the microbial fuel
cell can be improved.
