BIODEGRADABLE MICROORGANISM CARRIER FOR TREATING SEWAGE, ITS MANUFACTURING METHOD AND SEWAGE TREATMENT METHOD USING THE CARRIER

摘要

PPROBLEM TO BE SOLVED: To provide a biodegradable microorganism carrier for treating sewage as a carbon source of denitrifying bacteria, excellent in moldability and capable of being mass-produced at a low cost, a manufacturing method therefor and a sewage treatment method using the carrier. PSOLUTION: The biodegradable microorganism carrier for treating sewage is extrusion-molded into a cylindrical shape from a mixture comprising a biodegradable lactone type resin, a biodegradable resin other than the lactone type resin for adjusting the lactone type resin to extrusion-moldable melt tension and/or talc.
