Summary:Degradation activity ofPseudomonaspaucimobilis which degrade the refractory organic matter in sea water effectively was examined with the original experimental plant of rock bed contact-purification. First, the performance of the experimental plant withoutP. paucimobiliswas investigated. Theexperimental plant could purify turbidity most effectively, and No-Fines concrete (NFC) is superior to ordinary concrete and tires in removing SS and DOC. Degradation activity of organic matter of NFC was estimated to be 15-26% of that of sandy beach. Next, it was found that NFC supplemented withP.paucimobilisdegraded organic matter 1.4 times as much as NFC itself did.
