AI Summary & Key Takeaways
AI InsightWhile the phenol removal values of the systems in the planted and unplanted reactors were obtained as 89.65% ± 2.61 and 83.21%± 5.10 for CW1 respectively, they were 74.55% ± 14.17 and 73.44 % ± 19.07 for CW2 respectively.

Abstract
The purpose of this study is to examine the removal of phenol from olive mill wastewater in the planted/unplanted constructed wetlands containing filling material at different percentages. Two constructed wetland systems were developed with two CW1 reactors (containing 100% zeolite) and two CW2 reactors (containing 30% zeolite, 49% gravel and 21% sand) on a laboratory scale. Cyperus alternatifolius was used as the plant for both systems. The HRT (Hydraulic Retention Time) was determined as 2.8 days in system CW1 while it was 3 days in system CW2. The mean phenol concentration for the 89 days was 22.89 mg/l. While the phenol removal values of the systems in the planted and unplanted reactors were obtained as 89.65% ± 2.61 and 83.21%± 5.10 for CW1 respectively, they were 74.55% ± 14.17 and 73.44 % ± 19.07 for CW2 respectively.
Özet
Bu çalışmanın amacı, hacimce farklı yüzdelerde dolgu meteryaline sahip, bitkili/bitkisiz yapay sulakalanlarda karasudan fenol gideriminin incelenmesidir. Bu amaçla, laboratuvar ölçekli iki adet CW1 reaktörü (%100 zeolitli) ve iki adet de CW2 reaktörü (%30 zeolit-%49 çakıl-%21 kum) yapay sulak alan sistemi olarak geliştirilmiştir. Bitki olarak her bir sistemde Cyperus alternatifolius kullanılmıştır. CW1 sisteminde HRT (Hidrolik Alıkonulma Süresi) 2,8 gün iken, CW2 sisteminde 3 gün olarak belirlenmiştir. 89 günlük işletim süresince, ortalama fenol konsantrasyonu 22,89 mg/L dir. Sistemlerin bitkili ve bitkisiz reaktörlerinde fenol giderimi sırasıyla CW1 için %89,65 ± 2,61, %83,21± 5,10 iken CW2 için sırasıyla %74,55 ± 14,17 ve %73,44 ± 19,07 olarak elde edilmiştir.
