Opis:: The composition of the sediments formed in the process of stormwater pretreatment is diversified and depends on many parameters, mainly on the quality of stormwater and the land use of the catchment. The stormwater sediments are characterized by heterogeneous chemical and microbiological composition. The aim of this paper was the microbiological evaluation of the sediments from four stormwater catchments in terms of hazard to humans and the environment. The pH, and the content of organic and mineral matter were determined for the examined sediments. The microbiological analysis included the determination of the total number of psychrophilic, mesophilic, and coliform bacteria, including E. coli, and also the number of faecal Enterococci, Salmonella and Shigella. The study was conducted for fresh deposits and those stored for one year in order to determine the dynamics of changes in their biological activity.

Opis:: The degradation of 2-chlorophenol (2-CP) by persulfate was investigated. The kinetics of persulfate oxidation of 2-chlorophenol in aqueous solutions at various pH, oxidant concentration, temperature, Fe²⁺ > and Cu²⁺ ions content was studied. Maximum of 2-CP degradation occurred at pH 8. The oxidation rate of 2-CP increased with increasing the persulfate molar excess. The degradation process was significantly influenced by temperature – the higher temperature results in a faster degradation of 2-CP. The activation of persulfate by ferrous and copper ions was also studied. Results showed that persulfate is activated more effectively by iron(II) than copper(II) ions. A comparison of different persulfate activation methods revealed that heat-activation was the most effective. Under optimal conditions, in the presence of ferrous ions at 50 °C, complete degradation of 2-chlorophenol was achieved after about 30 minutes.
