<p><P>PROBLEM TO BE SOLVED: To provide a low-cost, space-saving, high-performance sewage treatment apparatus which can perform membrane filtration without using a well-known membrane separator, namely a precipitation method by gravity separation for separating and collecting treated water in a sewage treatment device using microorganisms. <P>SOLUTION: Various treatment systems composing the sewage treatment apparatus are not made of a heavy material, such as concrete, but of metallic materials or reinforced plastic, and are divided to a size transportable by a truck, and to unitize them. Bolting or fitting of the treatment systems facilitates assembly work. By properly assembling the systems to form the apparatus, a sewage treatment apparatus of a desired size and capacity can be installed at any time. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
