Effect of three environmental conditions on remedying lake water by ecological filter
Natural zeolite and coal cinder were layered as main packing medium of the ecological filter instead of traditional filling for the bioremediation of the static lake water in Northern China. The ecological filter was running in a combined upward and downward flow mode. Dynamic experiments were carried to study the effects of retention time and the ambient temperature on pollutants removal efficiency of the hybrid ecological filter. The function of plant was also studied by contrast test (one filter having dayflowers, another not). It demonstrated that the retention time played an important role in NH4+-N and tP removal; ambient temperature was significant for TP removal; the plant favored for TP and organic matter removal but had little effect on the Tn removal.
