<p>Waste water discharged from septic tanks and toilets into sewage contains salts contained in feces, chlorine compounds contained in toilet cleansers, and other salts and chlorine compounds contained in daily waste water. Since these salts and chlorine compounds inhibit the proliferation of microorganisms in the waste water, microbial degradation of organic and inorganic contaminants cannot well proceed in septic tanks and sewage disposal plants. Further, there arises an environmental problem due to the offensive smell. To solve these problems, toilet paper containing pineapple enzyme and at least one powder selected from among slag, porous ores and active carbon is provided. Each time the toilet paper is used, the substances capable of degrading chlorine compounds and eliminating offensive smell (i.e., pineapple enzyme and slug, porous ores or active carbon) are discharged into a stool together with feces and fed into the waste water or sewage in a septic tank. Thus, salts and chlorine compounds in the toilet sewage are reduced and the offensive smell is eliminated, thereby reliving the load in the processing of the waste water in the septic tank or a sewage disposal plant.</p> |
