왕궁 축산배수가 만경강유역에 미치는 영향 : 대장균을 중심으로 = Effects of Wanggung Livestock Wastewater on the Mankyung River Basin : On the Coliforms

다국어 초록 (Multilingual Abstract)

As Wanggung livestock wastewater flows in the Iksan stream, the Mankyung river has come under the influence of coliforms. But, in spite of containing an exceptionary large quantity of coliforms in the wastewater, the experimental studies on the coliforms distribution in the river basin are rarely performed up to now as compared with other water pollutants. This paper shows various characteristics about the coliforms(total coliforms, fecal coliforms) in the Mankyung river basin around the Iksan stream and the correlations of coliforms distributions with some major pollution indicators.
The results are as follows; It appeared that the positive detection numbers of FC were 94% of TC on the Mankyung river basin around the Iksan stream. And, statistical analysis of sampling data showed that most significant correlation occurred between FC and TC(r=0.850). In comparison of COD removal rate with coliforms reduction, reduction ratio of FC were some 5.4% higher than that of TC of 21.2% when COD removal rate reached to 18.5% experimentally. FC in the Mankyung river measured to increase in 3.7times from 854(MPN/100ml) to 3,155(MPN/100ml) after confluence of the Iksan stream.
