초록

The purpose of this study is an effectively new system composition for treatment of the stormwater runoff including non point pollutants and pollutants of CSOs and reuse of the treated stormwater runoff in urban areas. For proving efficiency of proposed system, a new pilot plant regarding the treatment of the stormwater runoff has been studied two kind systems on the urban basin. One system is composed with coagulation-flocculation, sedimentation and MF as noted SYSTEM Ⅰ and the other system consists of a HSF, BF and MF as noted by SYSTEM Ⅱ (mode 1, 2). Through the operation of pilot plant, optimal operation and characteristics of the removal of the substrates on nuit process was studied. The following in summarized as resulted in this study. There are two kinds of the operated SYSTEM as divided into Ⅰ and Ⅱ, in the case of SYSTEM Ⅱ in composed with mode 1 and mode 2 respectively. Removal efficiencies are shown higher in mode 2 of SYSTEM Ⅱ among operated SYSTEM of Ⅰ and Ⅱ which are composed with mode 1 and mode 2 respectively. According to the criterion on the korea standard of the quality of water in SYSTEM Ⅱ with mode 2, each removal rate is shown the following; CODcr 94.5 %, BOD 96.8% %, SS 100%, T-N 80. 5%, and T-P 99.2 % respectively. In the case of the reused water quality, SYSTEM Ⅱ are sufficient. While the SYSTEM Ⅰ is not satisfied to the standard of the reuse water quality.
