- The main removal mechanism of water contaminants in wetlands is microorganisms activities. One of them is a periphyton that lives on a submerged substratum. Therefore, a study of the influence of periphyton in construcetd wetlands which is important in improving water quality. The research objectives were to identify of the quality of influent, the composition of algae, the periphytone algae as primary producer, the influence of free water surface velocity factor, the quality of effluent, efectivity and eficiency of constracted wetlands. The study was conducted in Bandung City on January 2017. The results show that influent of sewage is contaminated with domestic wastewater. In constructed wetlands foundthree classes of benthic algae as periphyton, namely Bacillariophyta, Chlorophyta, and Cyanophyta. Periphyton algae play an important role in the transfer of oxygen into water colomn. The free surface velocity factor was strongly correlated to the percent removal of nitrate (r = 0.84) and very strong to the percent removal of total phosphate (r = 0.90) by periphyton. The quality of effluent that qualified grade III were total phosphate and COD parameter only. Effectivity of treatement were 6,6% ‐ 38,3% BOD, 6,0% ‐ 38% COD. Efficiency of treatment on the water discharge 0,01 L/s were 4,4% ammonium; 39,2% nitrat; 47,1% organic nitrogen; 53,6% phosphate total; 38,3% BOD; 38% COD; 76,5% detergent.
- Mekanisme utama penapisan kontaminan air pada lahan basah adalah aktivitas mikroorganisme. Salah satunya adalah perifiton yang hidup pada substrat terendam air. Oleh karena itu, diperlukan penelitian pengaruh perifiton dalam LBB, yang berperan dalam memperbaiki kualitas air. Tujuan penelitian adalah mengidentifikasi kualitas influen, komposisi alga perifiton, alga perifiton sebagai produsen primer, pengaruh faktor kecepatan aliran air permukaan, kualitas efluen, efektivitas dan efisiensi LBB. Penelitian LBB dilakukan pada bulan Januari 2017 di Bandung. Analisis kualitas air menggunakan SNI dan standar yang berlaku. Hasil penelitian menunjukkan air selokan sebagai influen LBB terkontaminasi air limbah domestik dan beberapa parameter melebihi kriteria kualitas kelas III. Ditemukan tiga kelas alga bentik perifiton (Bacillariophyta, Chlorophyta, Cyanophyta). Perifiton berperan dalam transfer oksigen kekolom air. Faktor kecepatan air permukaan berkorelasi kuat terhadap penapisan nitrat (r = 0,84) dan sangat kuat terhadap total fosfat (r = 0,90). Kualitas efluen yang memenuhi kriteria kelas III hanyaparameter total fosfat dan COD. Efektivitas pengolahan untuk BOD sebesar 6,6% ‐ 38,3% dan COD 6,0% ‐ 38%. Efisiensi pengolahan pada debit 0,01 L/s untuk amonium 3,4%; nitrat 39,2%; nitrogen organik 47,1%; fosfat total 53,6%; BOD 38,3%; COD 38%; deterjen 76,5%.
