STUDIES ON POLLUTION DEGREE OF TOILET PAPER AND DRAIN CHARACTERISTIC OF DRAIN PIPE(Environmental Engineering)

Abstract

This paper was researched for toileted paper exhausted from the water closets. The product of toilet paper is paper is provided for by JIS P 4501. Toilet paper dissolved in water, and examined whether to pollute water. The examination is mass, amount of the organism, SS, COD, BOD.
