Title (EN) TREATMENT METHOD FOR ORGANIC WASTEWATER AND USE OF SAME
(FR) PROCÉDÉ DE TRAITEMENT D’EAUX USÉES ORGANIQUES ET SON UTILISATION
(JA) 有機性廃水の処理方法及びその利用
Abstract:
(EN) The purpose of the present invention is to provide a treatment method by which, even for wastewater with organic constituents constituting a large portion of organic wastewater as a whole and suspended solids (SS) and with a large negative charge ratio, organic nitrogen constituents and phosphorus compounds can be efficiently separated and collected and good-quality separated water can be obtained by reducing the quantity of SS, BOD, COD, and nitrogen constituents in the separated water. Provided is a treatment method for organic waste water, in which a flock is formed by adding a polymer flocculant to organic waste water with organic nitrogen constituent content in relation to suspended solids (SS) being 4–50%/SS and organic nitrogen constituent content being 250–50,000 mg/L, and thereafter, the flock is separated from the organic wastewater by solid–liquid separation.
(FR) L’objectif de la présente invention est de fournir un procédé de traitement par lequel, même pour des eaux usées avec des constituants organiques constituant une grande partie d’eaux usées organiques dans leur ensemble et des solides en suspension (SS) et avec un rapport de charge négative élevé, des constituants d’azote organique et des composés de phosphore peuvent être efficacement séparés et collectés et de l’eau séparée de bonne qualité peut être obtenue par réduction de la quantité de SS, de DBO, de DCO et de constituants d’azote dans l’eau séparée. L’invention concerne un procédé de traitement d’eaux usées organiques, dans lequel un floc est formé par ajout d’un floculant polymère à des eaux usées organiques avec une teneur en constituants azotés organiques par rapport aux solides en suspension (SS) étant de 4 à 50 %/SS et la teneur en constituants d’azote organique étant de 250 à 50 000 mg/l, et ensuite, le floc est séparé des eaux usées organiques par séparation solide-liquide.
(JA) 有機性廃水全体及び浮遊固形物(SS)に占める有機性成分が多く且つマイナス荷電比が高い廃水であっても、有機体窒素成分及びリン化合物を効率良く分離回収でき、分離水のSS、BOD、COD、及び窒素成分を低減することで、良質な分離水が得られる処理方法を提供する。 浮遊固形物(SS)に対して有機体窒素成分が4%/SS以上、50%/SS以下であり、有機体窒素成分が250mg/L以上、50000mg/L以下である有機性廃水に、高分子凝集剤を添加してフロックを形成した後に、固液分離して前記有機性廃水から前記フロックを分離する、有機性廃水の処理方法。
