Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 複数のディッチの前段を嫌気ディッチとし、 後段を好気ディッチとし、好気ディッチにおいて生成し た硝化液を前段の嫌気ディッチへと両ディッチ間の圧力 差を利用して効率的に循環させるようにしたオキシデー ションディッチにおける処理水の循環装置を提供する。 【解決手段】 隣接して設置した複数のディッチ7、9 を用いて、汚水を生物処理するオキシデーションディッ チにおける処理水の循環装置において、ディッチのコー ナ部外側と、このディッチ7、9に隣接して設置したデ ィッチ7、9のコーナ部内側とを連通する処理水移送管 15を配置したことを特徴とする。 (57) [Summary] [Problem] An anaerobic ditch is set at the first stage of a plurality of ditches. The latter stage is an aerobic ditch, and a circulating device for treated water in an oxidation ditch that is configured to efficiently circulate the nitrification liquid generated in the aerobic ditch to the anaerobic ditch in the former stage by utilizing a pressure difference between the two ditches. provide. A plurality of ditches (7, 9) installed adjacent to each other are provided. In the apparatus for circulating treated water in an oxidation ditch for biologically treating wastewater, the outside of the corner of the dich and the inside of the corner of the ditch 7, 9 installed adjacent to the ditch 7, 9 are communicated with each other. The processing water transfer pipe 15 is arranged.
