In recent years, researchers pay increasingly attention on river ecological restoration at home and abroad. According to the practical situation of Tianjin Airport Economic Park river water environment and inter-external experiences, several ecological techniques, such as phytoremediation, artificial aeration and ecological riverbank, were adopted to river ecological restoration. And related operation...
Contaminant, such as heavy metals, organic pollutant, are released into the environment by mining, industry, agriculture to be severely harmful to people's health. Phytoremediation is a low-cost and environmentally-friendly technology to clean up polluted sites. This article makes systematic introduction of phytoremediation, from theory to application, particularly recent research achievement of poplar,...
The concentration of eighteen nutrients and heavy metals in E. crassipes collected from different sites in the North Zhejiang, China was concurrently studied. The concentration of the elements in whole plants was in the order of K (14896.92 μg g-1)>P (5775.78 μg g-1)>S (5596.38 μg g-1)>Ca (2368.92μg g-1)>Pb (2380.03 μg g-1)>Mn (852.90 μg g-1)>Fe (782.63 μg g-1) >Al (456.26 μg...
Biogas is a renewable primary energy source. The aim of the current study was to quantify the effect of temperature and feedstock size on biogas production of water hyacinth used for phytoremediation of rural domestic wastewater using anaerobic digestion (AD) process on a batch scale. This experiment consisted of two factors: AD temperature (mesophilic, 35°C) and thermophilic (55°C) and feedstock...
The efficiency and primary mechanism of phytoremediation of contaminated water with lambda-cyhalothrin, a synthetic pyrethroid pesticide, by water hyacinth (Eichhornia crassipes) was investigated. Around 11 g water hyacinth (Eichhornia crassipes Solms) grown in 250 ml culture solution was used to study the mechanism and effect of the removal of lambda-cyhalothrin in the growth chamber with a 14-h...
