Abstract

This study aimed to evaluate the performance of combined constructed wetland systems (vertical – horizontal flow) in removing organic matter, cultivated with Tifton 85 grass (Cynodon spp.) and cattail (Typha sp.), using pretreated swine wastewater (from anaerobic systems) at variable loading rates. The experimental system was composed of six constructed flooded systems. The flow was frequently monitored by direct measurement, and subsequently, the pH, influent, and effluent concentrations of the variables total solids (TS) and total suspended solids (TSS) and chemical oxygen demand (COD) were determined. The results showed that the average removal of total solids (TS) and total suspended solids (TSS) did not change significantly (p > 0.05) with increasing applied load in vertical flooded systems. While statistically significant differences (p < 0.05) were observed for ST in VFCW3 in Phase III (801–540 mg.L⁻¹, 33%) and for TSS in VFCW2, which showed 48% removal in Phase III (122–62 mg.L⁻¹, 48%), indicating that specific configurations can improve system efficiency. On the other hand, the average removal of total suspended solids (TSS) did not change significantly (p > 0.05) with increasing applied load in horizontal flooded systems. However, the average removal of total suspended solids (TSS) increased significantly (p < 0.05) with increasing applied load in horizontal flooded systems. Therefore, it can be concluded that the COD removal efficiencies, in general, increased with the increase in the applied organic load, reaching approximately 50% (307–271 mg.L⁻¹ VFC3 and 307–145 mg.L⁻¹ HFCW3) for the VFCW-HFCW set.

不同配置人工湿地对养猪废水有机物的去除效果研究

本研究旨在评估组合人工湿地系统（垂直-水平流）去除有机物的性能，用Tifton 85草（Cynodon spp.）和香蒲（Typha sp.）培养，使用预处理的猪废水（来自厌氧系统）在不同的负荷率下去除有机物。实验系统由6个已构建的淹水系统组成。通过直接测量经常监测流量，随后确定pH值、总固体（TS）和总悬浮固体（TSS）以及化学需氧量（COD）的变量浓度。结果表明，垂直驱水系统的总固形物（TS）和总悬浮固形物（TSS）的平均去除率随施加载荷的增加没有显著变化（p > 0.05）。而三期VFCW3中ST （801-540 mg）差异有统计学意义（p < 0.05）。L−1,33%)和VFCW2中的TSS，在III期（122-62 mg）中去除率为48%。L−1,48%)，说明具体配置可以提高系统效率。另一方面，水平驱水系统的总悬浮固体（TSS）的平均去除率随着施加负荷的增加没有显著变化（p > 0.05）。然而，在水平注水系统中，随着施加负荷的增加，总悬浮固体（TSS）的平均去除率显著增加（p < 0.05）。综上所述，随着施加有机负荷的增加，COD去除率总体上提高，达到50%左右（307 ~ 271 mg）。L−1 VFC3和307-145 mg。L−1 HFCW3)表示VFCW-HFCW集。
