| dc.description | Kajian dijalankan untuk mengkaji prestasi sistem tapak tumbuhan berskala pandu yang telah direka bentuk untuk merawat air sisa domestik. Teknologi fitoremediasi yang dicadangkan adalah mengguna pakai dua tumbuhan akuatik tempatan iaitu Scirpus grossus dan Lepironia articulata, yang ditanam dalam empat lajur dengan setiap lajur mengandungi tiga baris tangki gentian kaca bersaiz 1 m tinggi x 1 m lebar dan 2 m panjang. Lajur pertama (R1), kedua (R2) dan ketiga (R3) masing-masing ditanam dengan Scirpus groussus, Lepironia articulata dan campuran kedua-dua pokok terbabit, manakala tangki pada lajur keempat (R4) hanya mengandungi tanah yang bertindak sebagai kawalan. Air sisa domestik dari 105 buah rumah yang disalurkan ke dalam tangki pemendapan di Bukit Puteri, Universiti Kebangsaan Malaysia digunakan dalam kajian ini. Kesemua sampel daripada tangki sistem tapak tumbuhan dikumpul pada dua titik persampelan bagi setiap tangki pada pada setiap masa tahanan 0, 1, 3 dan 5 hari. Parameter kualiti air yang diukur adalah DO, pH, suhu, BOD5, COD, TSS, NH4 + dan PO4 -3. Selepas 5 hari masa tahanan, air sisa yang telah dirawat bagi setiap lajur menunjukkan peratusan penyingkiran seperti berikut: BOD5 (R1=99.5, R2=99.7, R3=99.5 dan R4=75.1%), COD (R1=96.2, R2=96.9, R3=96.6 dan R4=59.0%), TSS (R1=98.9, R2=99.0, R3=99.0 dan R4=75.0%), NH4 + (R1=100, R2=99.8, R3=99.7 dan R4=76.9%) dan PO4 - (R1=99.9, R2=99.2, R3=99.6 dan R4=69.1%). Berdasarkan Peraturan Kualiti Alam Sekitar (Kumbahan) 2009, air sisa domestik yang telah dirawat oleh sistem tapak tumbuhan telah mematuhi Piawai A selepas 3 hari masa tahanan. Kestabilan sistem tapak tumbuhan telah dikaji pada dua ketinggian air sisa dalam tangki iaitu 35 dan 45 cm. Keputusan pada kedua-dua ketinggian tersebut juga menunjukkan pematuhan terhadap Piawai A selepas 3 hari masa tahanan. Maka, perbezaan ketinggian air sisa telah memberi kestabilan yang baik terhadap sistem tapak tumbuhan dengan kelebihan memihak kepada ketinggian yang rendah (35 cm). Sebanyak sembilan bakteria dipencilkan daripada luar dan dalam tisu akar Lepironia articulata dan Scirpus grossus. Kesembilan pencilan bakteria terbabit dikenal pasti sebagai genus Bacillus, Enterobacter, Aeromonas dan Chromobacterium. Empat bakteria daripada pencilan tersebut menunjukkan keupayaan tinggi untuk mengurai NH4 + dan PO4 3- dengan masing-masing penyingkiran sebanyak 50 dan 40%. Bakteria tersebut juga mampu untuk menyingkirkan COD sehingga 80%. Oleh itu, sistem tapak tumbuhan yang dibina dan ditanam dengan tumbuhan Lepironia articulata dan Scirpus grossus telah menunjukkan kadar penyingkiran nutrien dengan berkesan daripada air sisa domestik.,This study examines the performance of an aerated pilot reed bed system that was designed for a domestic wastewater treatment. The proposed phytotechnology employed two Malaysian native aquatic plants, namely Scirpus grossus and Lepironia articulata, which were planted in four lines, each with three fiberglass tanks. Each tank measured 1m H x 1 m W x 2 m L, in each line. The first line (R1) was planted with Scirpus grossus, the second line (R2) with Lepironia articulata, the third (R3) one was planted with mix of both plants, and the last line (R4) was left unplanted as a control measure. The domestic wastewater collected in a sedimentation tank from 105 households in Bukit Puteri, Universiti Kebangsaan Malaysia was used for the entire experiment. Water quality (DO, pH, Temperature, BOD5, COD, TSS, NH4 + and PO4 -3) were monitored in all the systems, within four periods of retention time (0, 1, 3 and 5) days. Water samples were obtained from two sampling points in each reed bed box. After 5 days retention time, the characteristics of treated wastewater showed the following average removable percentage: BOD5 (R1=99.5, R2=99.7, R3=99.5 and R4=75.1), COD (R1=96.2, R2=96.9, R3=96.6 and R4=59.0), TSS (R1=98.9, R2=99.0, R3=99.0 and R4=75.0), NH4 + (R1=100, R2=99.8, R3=99.7 and R4=76.9) and PO4 - (R1=99.9, R2=99.2, R3=99.6 and R4=69.1). Based on the Malaysian Environmental Quality (Sewage) Regulations 2009, the proposed reed bed system has met with the Standard A quality after 3 days of retention time. The stability of reed bed system was investigated using two different heights of wastewater (35cm and 45cm) in the reed-bed tank. The characteristics of the wastewater after been treated in the reed bed of both heights indicated that both are at Standard A after 3 days retention time. However, wastewater at height 35cm indicated a better water quality in comparison to the 45cm height. Nine entophytic bacteria isolated from the external and internal tissue of Lepironia articulata and Scirpus grossus root system showed to belong to four genera Bacillus, Enterobacter, Aeromonas and Chromobacterium. Four bacteria among all isolates showed a high NH4 + and PO4 - biodegradation capability at 50 and 40% respectively. The bacteria showed potential COD biodegradebility to more than 80%. Thus, the pilot reed bed system with the native aquatic plants, Lepironia articulata, and Scirpus grossus demonstrated a very promising pollutant removal efficacy in the treatment of domestic wastewater.,PhD | |
