IRON BACTERIA SLUDGE FORMATION INHIBITION BODY AND FORMATION INHIBITION METHOD

PROBLEM TO BE SOLVED: To provide an iron bacteria sludge formation inhibition body allowed to be easily installed in at least a part of a groundwater pipeline or in the groundwater pipeline and capable of surely inhibiting formation of iron bacteria sludge and eliminating necessity of maintenance on a long-term basis, and to provide a formation inhibition method.SOLUTION: In an iron bacteria sludge formation inhibition pipe 1 constituting at least a part of a groundwater pipeline buried in a stratum and inducing or draining groundwater or installed in the groundwater pipeline to inhibit formation of iron bacteria sludge generated by iron bacteria always present in the groundwater, copper 8 and graphite 9 having respectively different corrosion potential levels are mixed or mutually adjacently arranged, the copper 8 and the graphite 9 are brought into contact with groundwater in the groundwater pipeline, and the copper 8 having a lower corrosion potential level out of the copper 8 and the graphite 9 generates copper ions for suppressing the growth or presence of iron bacteria.
