臨海工團 廢水가 沿岸海水에 미치는 影響에 관한 硏究 : 영양염류를 中心으로 on the nutrititional salts = A study on the influence to the shore sea water by the waste water of costal industrial estate

다국어 초록 (Multilingual Abstract)

This is the conclusion of the study on some nutritional salts included in the wastewaters and the sewages through 2 years, from 1986 to 1987. These are the wastewater being treated and discharged to the neighboring kwangyang Bay from the factories which are discharging the wastewater in the internal area of Yeochon Industrial Estate(Y.I.E), the sewage of Ssangbong area, the external area of Y.I.E, being discharged to the neighboring kamak Bay, the water treated by the night-soil treated plant in Yeosu city, the wastewater of Factory-H in this area and the sewage of the Yeondeung stream being flowed into Yeosu Harbor.
1. In Contents of PO_(4)-P and TKN in the wastewater being treated and discharged to the kwangyang Bay from 14 factories in Y.I.E the PO_(4)-P showed respectively 2.348mg/l at factory D and 2.020mg/l at factory A-I (main plant), and TKN showed 38.862mg/l and 71.337mg/l. These are the highest contents compared with the other factories. In the other factories, PO_(4)-P is 0.08-0.149mg/l and TKN is 0.350-11.994mg/l.
2. The ratio of treatment on PO_(4)-P and TKN by the current wastewater treatment is irregular and the average ratios of treatment in general show 85.4% in PO_(4)-P and 66.4% in TKN.
3. The loading amounts of the nutritional salts loaded the neighboring kwangyang Bay from the waste and treated waste of 14 factories in Y.L.E are 16.77kg/l, in PO_(4)-P and 484.46kg/l each when the water is originally wasted.
4. The contents of the nutritional salts in the Ssangbong sewage A and B of the external area Y.I.E discharged to kamak Bay, the treated water of the night-soil treated plant in Yeochnn city and the waste and treated water of factory-H in Yeosu are as follows. PO_(4)-P are 0.689mg/l, 1.085mg/l, 1.103mg/l and 0.0027mg/l in order and TKN are 15.654mg/l, 24.194mg/l, 28.675mg/l and 0.980mg/l.
5. The contents of PO_(4)-P and TKN in the Yeondeung stream which han an indirect influence on kamak Bay are 0.884mg/l and 15.234mg/l each, and the loading amounts by one day are 38.633kg and 665.756kg.
6. According to the measurement result, the entire area of kamak Bay close by the land also is the same. But the other areas belong to the Eutrophicated sea area.
