摘要: The aim of the study is to assess influence drainage layer made reactive material Polonite(®) on water retention and P-PO(4) concentration in runoff. A column experiment was performed for extensive substrate underlined by 2 cm (SP) same without supporting as a reference (S). leakage phosphorus ranged from 0.001 0.082 mg P-PO(4)·L(-1), with average value 0.025 P-PO(4)·L(-1) S 0.000-0.004 SP experiment, respectively. efficient reducing P outflow green roof 96%. effluent volumes experiments amounted 61.1 mL (5.8-543.3 mL) 46.4 (3.3-473.3 irrigation rate 175.5 (6.3-758.0 mL). ability 65% 74%, Provided materials, layers implemented urban areas rain delaying runoff also work protection quality.
