TAILIEUCHUNG - Nghiên cứu đánh giá hiệu quả ứng dụng công nghệ đất ngập nước kiến tạo xử lý nguồn nước mặt ô nhiễm
Mục đích nghiên cứu nhằm đánh giá hiệu quả ứng dụng công nghệ đất ngập nước kiến tạo xử lý nguồn nước mặt ô nhiễm. Mô hình thí nghiệm được vận hành với 2 tải trọng thủy lực 500mL/phút/m2 (T1) và 1500mL/phút/m2 (T2). Loài cỏ sậy phổ biến (Phragmites australis) đã được chọn lựa phục vụ cho nghiên cứu. | Nghiên cứu đánh giá hiệu quả ứng dụng công nghệ đất ngập nước kiến tạo xử lý nguồn nước mặt ô nhiễm VNU Journal of Science: Earth and Environmental Sciences, Vol. 35, No. 2 (2019) 11-22 Original Article A Study to Assess the Effectiveness of Constructed Wetland Technology for Polluted Surface Water Treatment Nguyen Cong Manh1, Phan Van Minh1, Nguyen Tri Quang Hung2, Phan Thai Son3, Nguyen Minh Ky2,* 1 Research Center for Environmental Technology and Natural Resource Management, Nong Lam University, Hamlet 6, Linh Trung Ward, Thu Duc District, Ho Chi Minh City, Vietnam 2 Faculty of Environment and Natural Resources, Nong Lam University, Hamlet 6, Linh Trung Ward, Thu Duc District, Ho Chi Minh City, Vietnam 3 Institute for Environment and Resources, Vietnam National University, 142 To Hien Thanh Street, Ward 14, District 10, Ho Chi Minh City, Vietnam Received 13 March 2019 Revised 06 April 2019; Accepted 06 June 2019 Abstract: The study aims to assess the applying effectiveness of constructed wetland technology for polluted surface water treatment. The experimental models were operated with 2 hydraulic loadings of 500mL/min/m2 (T1) and 1500mL/min/m2 (T2). The reed grass (Phragmites australis) was selected for the studying process. The surface water resource was removed from the pollutant components (TSS, BOD5, COD) and harmful microorganisms (fecal coliform) which aim to protect the water quality and aquatic ecosystems. The results showed the treatment effectiveness of loading of 500mL/min/m2 is higher than the loading of 1500mL/min/m2, especially in the reed planting trial. In particular, the treatment efficiency of pollutants such as TSS, BOD 5, COD reached a high rate of 85%, 90%, and 87%, respectively. In addition, ANOVA statistical analysis showed the effectiveness of water quality parameters belong to two loadings were statistically significant (P VNU Journal of Science: Earth and .
