Title:
METHOD AND APPARATUS FOR TREATING WASTEWATER
Document Type and Number:
Japanese Patent JP3653422
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce an amount of waste and the initial cost and running cost of the titled apparatus.
SOLUTION: In this wastewater treating apparatus, the organic matter in the wastewater can be treated with the microbes contained in biological sludge 31 and fluorine in the wastewater can be treated with chemical sludge containing calcium since the organic matter-containing fluorine wastewater is treated in a reaction tank 3 where the biological sludge 31 and the chemical sludge containing calcium are introduced. Therefore, since the organic matter in the wastewater and the fluorine in another wastewater different in chemical properties from the former can be treated in one reaction tank 3, two reaction tanks are not necessitated to reduce the initial cost.
