In order to investigate the characteristics of the non-biodegradable material, the $BOD_5/COD_{Cr}$ ratio was used. The average ratio of industrial complex's influent wastewater was 2.29~2.96, the effluent ratio was 4.29~19.0. The removal efficiency of $UV_{254}$ by physicochemical treatment was 22.8~94.7% and 5.3~77.2% by biological treatment, respectively. Of the wastewater removal efficiency for each of the items, the $BOD_5$ treatment efficiency was the greatest at 97.3% and the color & TN treatment efficiency was 40~70%. The study of the economical assessment showed that the complex as well as the individual companies spent 722~1,298 won for each ton of treated wastewater. All of the wastewater treatment facilities spent the most money on chemicals needed to treat the wastewater. The total cost for Nylon manufacturing wastewater treatment plant was the greatest while the total cost for cotton manufacturing wastewater treatment plant turned out to the lowest. As respects of removal efficiency and economocal assessment, Polyester A and Cotton manufacturing wastewater treatment plants were better effective than a dyeing industrial complex wastewater treatment plant.
