Water pollution in Jeonjucheon

Until the end of the 1990s, all kinds of living sewage that occurred in the city center came to Jeonjucheon, which made Jeonjucheon full of stench and filth. At that time, the water pollution in Jeonjucheon was so serious that it smelled bad even in the distance, and Jeonjucheon's water was considered to be shit among the citizens of Jeonju. It was even said that if my feet fell into the water while crossing the stepping stone, my skin was itchy. Jeonjucheon is contaminated with BOD, COD, total nitrogen, and total human, and overall it shows a tendency to increase the degree of pollution as it goes from upstream to downstream. In the lower part of Jeonjucheon, the amount of COD, total nitrogen, and total saccharifications is the odds of the upper limit of the 5th grade based on appeal. It directs the main sources of pollution for pre-state sewage BOD, COD, total nitrogen, and total phosphorus. The waste landfill is likely to be a source of pollution for BOD and COD, and since total nitrogen is highly polluted from the upstream, it is thought that the pollution effect caused by agricultural activities is also large. Jeonjucheon is having an important effect on BOD, COD, total nitrogen, and total human pollution in Mangyeong River. As a result of calculating the pollution load in August 1999 using actual flow and water quality analysis, the BOD (0.49 ton/day), COD (0.86 ton/day), total nitrogen (1.61 ton/day), and total phosphorus (0.01 ton/day) were about 5 times, 7 times, 7 times, and 36 times higher, respectively, respectively.

Then, in 1998, Jeonju City made a plan to restore Jeonjucheon to an ecological river, and the restoration project started in 2000. And now it has been reborn as an ecological river with first-class water quality upstream. Currently, otters and shiri, which are natural monuments, are native to the upstream of Jeonjucheon, which is unique among the major urban rivers across the country. The successful ecological river restoration project in Jeonjucheon is considered an exemplary example of ecological restoration of urban rivers.

History in jeonjucheon

Jeonjucheon provided the people of Jeonju with a market where various letters are traded as a space of life, and it functioned as a semester magazine. Since near college, Jeonjucheon's vitality has rapidly disappeared, and Jeonju's identity has been stranded. Jeonjucheon often goes from the source to the place where it joins the Mangyeong River, but narrowly, it refers to Hacheon Bay, which wraps around Jeonju-si. It is divided into Namcheon, Seocheon, recommendation, etc. Namcheon is Jeonjucheon, which runs from Hanbyeok Dang to Dasan, and it is named because it flows to the south of Jeonju, and Seocheon is also a river that flows to the west of Jeonju. The recommendation refers to Jeonjucheon from Samrye to joining the Mangyeong River. But according to the old records and some evidence, unlike the current water-enjoying of Jeonjucheon, it flowed straight north along the eastern Groom of Jeonju. In fact, in 1939, when the mother barrel in the northwest of Deokjin Pond dug about 10 underground under the pond, there was a record that a lot of friends came out during that time.
