Abstract
The aim of the research was to assess the effectiveness of the removal of selected active compounds in a hybrid hydrophyte sewage treatment plant. The research was carried out in a sewage treatment plant located in the Dębowa Kłoda commune, approximately 1.5 km from Lake Bialskie in the Natura 2000 area. The facility was built in 2020 and its capacity is 180 m3/day. The treatment plant consists of four parts, i.e. mechanical, biological and chemical, and a wetland system for sludge drainage. After mechanical cleaning in a sieve-sand trap and primary settling tank, the sewage is fed by pumps to 6 beds with vertical flow (VF type), and then by gravity to 6 beds with horizontal flow (HF type). The area of each of the deposits is 300 m2 and they are filled with coarse sand and planted with common reed (VF deposits) and giant miscanthus (HF deposits). The last element of the treatment plant is a system of 3 parallel filters filled with lime-silica rock (Rockfos material), which are used to remove phosphorus from wastewater. Wastewater samples for testing were collected from 5 points of the treatment plant: 1) raw wastewater, 2) after primary settling tank, 3) 1 VF type bed, 4) after 2 HF type beds and 5) after the P-filter. In the collected samples, caffeine, chloroquine, diclofenac, ketoprofen, naproxen, clindamycin, and carbamazepine were determined using an ion mobility spectrometer with a high-pressure liquid chromatograph (UPLC/QQQ-IMS-IT). The tests were carried out in three repetitions. Based on the research, it was found that the tested hybrid hydrophyte sewage treatment plant, with the exception of chloroquine, successively reduces the level of active compounds at individual stages of sewage treatment. It is worth noting that the concentration of caffeine is no longer measurable in 1 VF bed. Compared to the concentrations determined in the raw sewage, the concentration in the sewage treated after the P-filter is lower by 94% for ketoprofen, 99% for naproxen, 90% for carbamazepine, 67% for clindamycin and 83% for diclofenac. In conclusion, it should be stated that the tested hybrid hydrophyte sewage treatment plant reduces the content of active compounds by about 90%, but not all pharmaceuticals are fully removed.
Investments in Scientific Activity were co-financed from the State Budget. Ion Mobility Spectrometer with High Pressure Liquid Chromatograph (UPLC/QQQ-IMS-IT).
