| Summary: | Surface runoff water (SRW) from highways is highly polluted and has negative impact on adjacent areas and water bodies. The article describes constructed wetlands (CW), including detention ponds and facilities for sorption post-treatment, one of the simplest methods to treat the SRW from highways. It is established that filter cassettes (FCs) based on gabion constructions (GC) and loaded with shungite rock (SR) are used as sorption post-treatment facility. One of the reasons for the unsatisfactory operation of such facilities on the St. Petersburg Ring Road (the SPb RR) has been analyzed. It is shown that the SR recommended for loading into the FC has a fractional composition of 2÷4 cm and thus mostly providing a turbulent filtration mode of SRW passing through the facility. The impossibility of using SR with the optimal towards sorption treatment fractional composition of (0.1÷0.3) cm within the existing GC is shown. It is also shown that the use of permeable for SRW containers — the filter cartridges (such as FOPS® filters) is shown to be one of the simplest and most effective ways of using SR of optimal fractional composition and working with a large amount of sorption materials. The approach to the organization of complex multistage treatment of surface runoff is shown. |
