    Abstract: Landscape function has become the key function of China's urban water. However, this function is hardly to be guaranteed for increasing water pollution. The identification of apparent pollutants' state can produce significant effect on the in-depth study of apparent pollution, such as the cause and formation mechanism research, which also can provide technical support to its warning, prevention, control and engineering management. The non-dissolved substances in 200 water samples were removed by the using of 0.45 μm membrane, which were collected in Suzhou's 30 rivers. Comparing the turbidity and chromaticity which were detected in both original and filtrated water respectively, results showed that the majority of the turbidity and chromaticity were produced by the non-dissolved substances. Through measuring the content of apparent pollutants at different states (the dissolved and the non-dissolved) respectively and the permanganate index (Im) of suspended solids in extreme black, dark green and yellow water, summarizes the effect of the non-dissolved substances on extreme polluted water apparently. The experiment indicates that most sulfide and chlorophyll a (Chla) exit in the form of the non-dissolved as well as that silt, clay and other non-dissolved inorganic substances contributes to yellow water's apparent pollution, which demonstrated that the main cause of landscape water's apparent pollution was the non-dissolved substances.
