“…As the nutrient uptake efficiency is important, much work has been done on the floating plant chosen for the treatment of polluted waters [20,21], improvement of the purification capability of FTWs [7,13,17], and analysis of factors influencing the performance of the FTWs [8,10,[22][23][24]. Among studies on FTWs, the purification effect of FTWs on eutrophicated water has been reported from several works [11,13,16,17,25].…”

“…In the past 30 years, the FTWs have been tested and applied in laboratories and at pilot scales [3][4][5][6][7][8][9]. Characterized by no extra land demand and adaption to a wide range of water depth, FTWs have been widely used in the treatment of domestic wastewater [10], river water [7,11,12], lake water [5,13,14], agricultural runoff [4,15], swine sewage [16], rainfall [17], storm water [18] and urban runoff [19].…”

“…There have been only a few reports concerning the remediation of heavily polluted rivers (e.g. Sun et al, 2009;El-Sheikh et al, 2010;Wu et al, 2011), and most of these studies were focused on off-line treatment or laboratory work (e.g. Palmer, 2009;Cao et al, 2012).…”

a b s t r a c tRiver pollution is becoming a serious problem worldwide. A field-scale experiment was undertaken to remediate a heavily polluted river using a combined engineering approach of aeration, microorganisms, biological aerated filtration, artificial biofilms and ecological floating beds. Prior to remediation, the river water was black, anoxic and highly sulfidic. With remediation, the chemical oxygen demand decreased from ∼250 to ∼50 mg L −1 , NH 4 + -N decreased from ∼27 to ∼4 mg L −1 , sulfide decreased from ∼3 to ∼0.3 mg L −1 , and total suspended solids decreased from ∼270 to ∼40 mg L −1 . At the same time, dissolved oxygen increased from ∼0.1 to ∼3.5 mg L −1 , and water clarity increased from ∼6 to ∼40 cm. Furthermore, the unpleasant odor emanating from the polluted river was also stopped, and local farmers have begun using the water for irrigation. This field-scale experiment thus indicates the potential usefulness of this combined engineering approach to remediate heavily polluted rivers.

“…Thus, various strategies to control eutrophication in lakes have been proposed, such as control of external nutrient loading, sediment dredging, sediment curing, and phytoremediation (Murphy et al 1999;Desprez 2000;Ye et al 2011). Among these, phytoremediation is very attractive and widely used because of its low cost and easy management (Sun et al 2009). Use of submerged plants to control the nutrients and algal bloom in eutrophic lakes is a generally accepted lake management strategy.…”

An ecological engineering project with confined growth of 1.5 km 2 of Eichhornia crassipes was implemented to remove pollutants in Lake Dianchi. To assess the ecological effects of this project on benthic macroinvertebrate assemblages, a 1-year investigation at the areas inside and outside E. crassipes mats was conducted from May 2013 to May 2014. All the 10 sampling sites in the areas were grouped into two statistically significant clusters mainly corresponding to inside and outside E. crassipes mat areas (EMAs), by clustering analysis. E. crassipes reduced the densities of pollution indicator taxa (e.g., Oligochaeta and Chironomidae larvae); thus, the total densities of benthic macroinvertebrates at the area inside EMAs (mean 328.2 ind./m 2 ) were slightly lower than that at the area outside EMAs (mean 505.6 ind./m 2 ). Four functional feeding groups including 38 species of benthic macroinvertebrates were collected at the area inside EMAs, while only three functional feeding groups containing 17 species were collected at the area outside EMAs. The biodiversity indices (Shannon-Weiner, Margalef, Simpson, and Peilou
