  1. 1. Biokolets påverkan på dagvattenkvaliteten i regnbäddar

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Maja Hammarstedt; Wilma Insulander; [2023]
    Keywords : Biokol; dagvatten; regnbädd; vattenkvalitet; föroreningar; StormTac; dagvattenrening; näringsämnen; växtbädd; urban miljö;

    Abstract : Klimatförändringar och en större andel hårdgjorda ytor i städerna bidrar till en ökning av dagvatten som måste ledas bort. För att förhindra överbelastade VA-ledningar behöver dagvattnet fördröjas inom avrinningsområdet. En stor del av dagvattnet innehåller föroreningar från bland annat vägar, parker och industriområden.
