We have investigated water quality (pH, DO, SS, COD and total coliform) and flow rate of the stream, and found that the stream kept pure condition at the point of pH, DO and SS. At the point of COD and total coliform, the stream was almost clean condition, but there was sometimes sudden pollution. The effect of the activated carbon purifier appeared unclear, but after considering all the factors, it appeared that pollutants were a little reduced in the result.}, pages = {25--30}, title = {活性炭浄化装置による小河川水質の直接浄化}, volume = {33}, year = {1999} }
