Simulation of wastewater dispersion of recycling scrap paper from Muc Son Paper factory to the downstream Chu river

This research simulates and forecasts the area as well level of pollution dispersion Muc Son Paper Factory’s wastewater to downstream Chu River under two scenarios: Scenario 1 - treatment system is broken; efficiency equal 0; 2 working with its designed capacity. The applied results MIKE 11 model show that: impacted from plant’s discharge 0.2 km upstream confluence point. simulation TSS, BOD5 COD contents being 18.3–35.7 mg/L, 8.3–17.2 mg/L 12.2–23.7 respectively, negatively affect water environment river. are then compared measured data confirm reliability model. a scientific practical basis for factory operate manage quality output ensure environmental regulations.
