| This study has shown the characteristics of TOXs formation appeared according to the initial temperature after chlorine is input. chlorine dose, and situation condition respectively in the subject of the source of water S, Y. E. and H. which are used as water supply sources in the north area of Jeju. NH₃-N, N0₃-N, Cl^(-), TOC in the source of water E, H were much more detected than those in S, Y, but there was no distinctive difference in the amount of the TOXs formation of the raw water before chlorination. The feature was clearly seen that the more chlorine dose which was injected after break-point, the more the amount of the TOXs formation when the initial temperature was either 10℃: or 209: : yet, there was little relevance as the initial temperature was 30 ℃ and the amount of the TOXs formation in a dark room was larger than that in out of the room on the situation condition. It can be inferred that all the NH3-N should disappear when the ratio of 6121 NH3-N was over 10 with no relation to the initial temperature, chlorine dose, situation condition. and the amount of the TOXs formation would be around 29.345-65.919 ㎍Cl/ℓ when the ratio was 5 and below and would be 41.516-94.520 ㎍Cl/ℓ when the ratio 7.32 was close to 7.6 which is generally used theoretical value in a actual water plant. We can generally jude that the amount of the TOXs formation was increased in relation to that of chlorine dose, and this tendency was clear out of the room more from a dark room when initial temperature was high. The characteristics of TOXs formation according to situation condition was detected in order of a dark room, out of the room. This explains to use that the consumption of the injected chlorine which resulted from dissolved chlorine by light, activities of microbes, and formed algae to the reduction of the residual chlorine, and this had a effect on the amount of the TOXs formation. |
