Abstract Common porous concrete templates (CPCT) and advanced porous concrete templates (APCT) were employed in this study to construct wetlands for their applications in pollutant removal from storm runoff. The planting ability of the concrete was investigated by growing Festuca elata plants in them. Strength of the porous concrete (7.21 ± 0.19 Mpa) decreased by 1.8 and 4.9% over a period of six and 12 months, respectively, due to its immersion in lake water. The height and weight of Festuca elata grass growth on the porous concrete were observed to be 12.6–16.9 mm and 63.4–95.4 mg, respectively, after a duration of one month. Advanced porous concrete template based constructed wetland (APCT-CW) showed better removal of chemical oxygen demand (COD) (49.6%), total suspended solids (TSS) (58.9), NH3-N (52.4%), total nitrogen (TN) (47.7%) and total phosphorus (TP) (45.5%) in storm water, when compared with the common porous concrete template based constructed wetland (CPCT-CW) with 20.6, 29.8, 30.1, 35.4 and 26.9%, respectively. The removal of Pb, Ni, Zn by the CPCT-CW unit were 28.9, 33.3 and 42.3%, respectively, whereas these were 51.1, 62.5 and 53.8%, respectively, with the APCT-CW unit. These results demonstrate that the advanced porous concrete template in constructed wetland could be employed successfully for the removal of pollutants from urban storm water runoff.

The majority of storm runoff pollution is trapped in particles smaller than 100 μm in diameter. Solid particles smaller than 100 μm in diameter are not easily separated by conventional types of hydrodynamic separator, and remain in suspension in overflow. To overcome this problem, a HDFS (hydrodynamic filter separator) has been developed for treatment of the microparticles in urban storm runoff. We conducted a laboratory scale study on treatable potential of microparticles using HDFS that combined HDS with perlite filter. To determine the efficiency for various operation conditions, a series of experiments was performed with different solids concentrations and surface loading rate. The operation ranges of surface loading rates were 100 to 2,800 m3/m2/day, and influent solids concentrations were varied from 800 to 1,900 mg/L. Also, the particle size distribution was monitored to investigate the effects of surface loading rates on the particle size. Results indicated that the HDFS-Inside type showed greater efficiency at solids separation than the other type.

In this paper the substance flow analysis (SFA) method was employed to map the water, COD-C, TN-N flows in urban drainage system, focusing on the pathways of contaminants to urban water environment. As case studies, four cities were selected for the comparative assessments using the statistical data of 2011.Through examining the fluxes of three sources (effluent of WWTPs, wastewater discharged without treatment, and urban storm runoff) of COD-C and TN-N emission, analysis and discussionwere made based on different units of measurements.The results showed that the load of COD-C was in the range of 16.50~80.25 kg/y/capand 131.44~227.58 t/y/km2, and TN-Nwas in the range of 1.20~5.43 kg/y/capand 9.57~23.18 t/y/km2.Taking considerations ofproportional relationship among the three origins, urban storm runoff released the majority of COD-C to receiving water, accounting more than 60% of the total. For TN-N flows, effluent of WWTPs and urban storm runoff wereidentified as the major contributors, accumulated contribution of 85%.Thus, the outcomes from these substance flow analyses, suggested that a reduction in pollution could be achieved by improvingstormwater management and upgrading emission standard of WWTPs, and proved itself as an effective tool for urban wastewater management as well.
