の前処理装置。 This is a pre-treatment device for introducing organic wastewater to the biological treatment process, and is equipped with a fine screen that separates the organic wastewater and a centrifuge to which the screen separation liquid obtained by the fine screen is supplied. The centrifuged liquid obtained by the centrifuge is configured to be guided to the biological treatment process, and the SS discharged from the centrifuge and the sludge generated in the biological treatment process are passed through the fine screen. What is claimed is: 1. A pretreatment device for organic sewage, comprising a path for supplying organic wastewater, and further comprising a polymer flocculant injection section in the path.
