“…하고 있으며 (Lee at al., 2007;MAF, 2009), 특히 질소는 작 물에 흡수되고 약 33∼43% 정도가 폐양액으로 배출되고 있 어 인근 수계 부영양화의 주요인이 되고 있다 (Lee et al, 1996;Lee et al, 1999). 폐양액 내의 질소와 인은 수질 오염을 유발시키는 오염원 이지만 대부분이 작물 흡수가 용이한 형태이므로 농업적 측 면에서 볼 때는 비료로써 재활용 가치가 높을 것으로 판단된 다.…”

In order to improve T-N and T-P removal in HF (horizontal flow)-HF hybrid constructed wetlands by natural purification method for treating the hydroponic wastewater in greenhouses, the efficiency of water treatment as affected by the injection method of hydroponic wastewater, the addition of special filter media, the particle size of filter media, and the injection ratio of hydroponic wastewater in 1 st HF and 2 nd HF beds were investigated in small-scale HF-HF hydroponic wastewater treatment apparatus. Removal rate of T-P in the water in HF-HF hydroponic wastewater treatment apparatus with calcite as affected by addition method of special filter media was higher than that in HF-HF hydroponic wastewater treatment apparatus with other filter media. Removal rate of BOD, COD, SS, T-N and T-P in the water in mixed filter media with calcite were 86, 84, 87, 50 and 97%, respectively. Removals of pollutants except for T-P in the water were slightly different. Therefore, it should be considered that the removal rate of T-P was good for calcite in HF-HF hydroponic wastewater treatment apparatus. To improve T-N and T-P removal, the optimum particle size of filter media was 1.2 mm, and the optimum injection ratio (1 st HF bed : 2 nd HF bed) of hydroponic wastewater was 60:40.

“…Hydroponics cultivation dumps nutrients directly into streams (Figure 1C), while soil cultivation allows nutrients accumulated in the soil to leach out during rainfall (Figure 1D). There are cases of wastewater discharged from greenhouse crop cultivation and nutrients accumulated in the soil, contaminating groundwater, streams, rivers, and agricultural fields [34][35][36][37]. For this reason, countries such as the Netherlands, Spain, and Japan are developing recycling methods that do not discharge wastewater [38][39][40][41][42].…”

As greenhouse horticulture continues to increase in South Korea, the effects of metal(loid)s from wastewater discharges on stream sediments were analyzed. A total of 106 samples were analyzed for cadmium (Cd), boron (B), copper (Cu), nickel (Ni), lead (Pb), zinc (Zn), chromium (Cr), manganese (Mn), and iron (Fe). The coefficient of variation (CV) of the metal(loid)s components was 96.58% for Mn, 93.40 for Zn, 62.47 for B, 58.90 for Pb, and 58.14 for Cd, suggesting anthropogenic sources. Correlation analysis suggested a cumulative source for Cd-Zn and B, and cluster analysis suggested an anthropogenic source for Cu, Pb, B, and Mn. The contamination factor (CF) suggested the need to trace the source of contamination to Pb (3.21 ± 1.89) and B (1.33 ± 0.83) and EF to Pb (3.30 ± 1.81) and B (1.44 ± 0.94). The analytical results identify anthropogenic sources of Pb, B, and Cd. The high contamination of Cd suggests the influence of mining areas, and Pb suggests the influence of traffic, fertilizers, pesticides, and fossil fuels in greenhouses, in addition to the influence of mines. B confirmed the impact of the facility’s vegetable wastewater and suggested the need to further examine the cumulative impact of Mn, Fe, etc. By utilizing the facility horticulture wastewater for ecological restoration and other agricultural uses, we aim to prevent stream sediment pollution and realize a sustainable agricultural environment.
