Abstract
In this neutralizing apparatus, aerobic microorganisms are propagated on a vinylidene chloride packing material provided in a neutralization tank . The aerobic microorganisms produce nitric acid ions from organic alkaline wastewater introduced from a raw water tank and thereby the organic alkaline wastewater is neutralized. Thus, various kinds of alkaline wastewater can be neutralized without using a mineral acid as a poison such as hydrochloric acid or the like.
