摘要

PURPOSE: A preparation method of purifying agent for sewage, wastewater excrement, green algal, and red tide by using peat, fly ash, and bottom ash is provided. Fly ash or bottom ash is transformed into allophane and imogolite as purifying agent. Optionally peat is added for generating activated humus soil as purifying agent. CONSTITUTION: According to the method, fly or bottom ash is mixed with alkali solution at 90-180 deg.C for 8-24 hrs. Then, zeolite is generated. Generated zeolite is dewatered and cleaned. And acid is added thereto. Zeolite added acid is mixed at 90-100 deg.C for 4 hrs. Then allophane and imogolite are generated. Allophane and imogolite are dewatered and dried. Consequently generated allophane and imogolite are used as purifying agent.
