摘要

PURPOSE: An improving agent for water quality and sediment quality is provided not to use anhydrite and quicklime, and to use desulfurized gypsum generated as a by-product of a fluidized bed boiler, thereby improving water quality and sediment quality, and removing green algae, red tide, and other harmful materials.;CONSTITUTION: An improving agent for water quality and sediment quality comprises 20-80 weight% of desulfurized gypsum, and 20-80 weight% of one or more kinds of desulfurized gypsum mixtures selected from baby square for manufacturing paper, fly ash, dolomite, zeolite, clay, and light-burned dolomite. The desulfurized gypsum is generated as a by-product of a fluidized bed boiler. The desulfurized gypsum mixture comprises 10-50 weight% of baby square for manufacturing paper, 10-50 weight% of fly ash, 10-50 weight% of zeolite, and 10-50 weight% of light burning dolomite.;COPYRIGHT KIPO 2012
