This research make use of Old-Zhuoshui river as a research case stady, utilize QUAL2K water quality modeling imitate rivers water quality state, and with LINDO program to estimate the assimilative capacity, then understanding the pollution carrying capacity of Old-Zhuoshui river, using this as the valuation of the measure result of the pollution improvement. According to the mode simitation result in Old-Zhuoshui river pollution improve valuation. In first object : reach to standard its BOD and NH3-N to cut down quantity have to 19% and 14% above. In back object : reach to standard its BOD and NH3-N to cut down quantity have to 46% and 36% respectively above.
