Control concept and countermeasures for shallow lakes' eutrophication in China

JIN Xiangcan, LU Shaoyong, HU Xiaozhen, JIANG Xia, WU Fengchang

Frontiers of Environmental Science & Engineering 2008, Volume 2, Issue 3,   Pages 257-266 doi: 10.1007/s11783-008-0063-3

Abstract: Research on lake eutrophication in China began in the early 1970s, and many lakes in China are now knownLake eutrophication has been showing a rapidly increasing trend since 2000.Investigations show that the main reasons for lake eutrophication include a fragile lake background environmentMajor mechanisms resulting from lake eutrophication include nutrient recycling imbalance, major changesSome concepts for controlling eutrophication should be persistently proposed, including lake catchment

Role of biologic components in a novel floating-bed combining

Hailiang SONG, Xianning LI, Wei LI, Xiwu LU

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 2,   Pages 215-225 doi: 10.1007/s11783-013-0587-z

Abstract: A novel floating-bed incorporated with water spinach ( ), Asiatic clam ( ), and carrier media supported biofilm was developed for eutrophic water purification. The contributions of each biologic component to the removals of total nitrogen (TN), total phosphorus (TP) and Chl.a were examined. The nutrient removals due to the direct uptake by either water spinach or Asiatic clam were less than 10%, suggesting a negligible role of biologic assimilation and leaving the biofilm as the indispensable biologic component in the floating-bed. Chl.a was reduced mainly by Asiatic clams via filter-feeding. Meanwhile, the digestion and excretion of Asiatic clams benefited the proliferation of nitrifying and denitrifying bacteria, resulting in the improvement of TN removal. In summary, the synergetic effects of water spinach, Asiatic clams and biofilms would promote the eutrophic water treatment performance of floating-bed in comparison with the conventional floating-bed with vegetation as the single biologic component.

Restoration of hyper-eutrophic water with a modularized and air adjustable constructed submerged plant bed

Jinzhong LI, Xueju LI, Shujuan SUN, Xuegong LIU, Suiliang HUANG

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 4,   Pages 573-584 doi: 10.1007/s11783-011-0363-x

Abstract: A modularized and air adjustable constructed submerged plant bed (CSPB) which can be used to restore the eutrophic water is introduced in this paper. This plant bed helps hydrophyte grow under poor conditions such as frequently changed water depth, impaired water transparency, algae bloom and substantial duckweed in summer, which are not naturally suitable for growing hydrophyte. This pilot study in Waihuan River of Tianjin, China, revealed that reduction of Chemical Oxygen Demand (COD), Total Nitrogen (TN) and Total Phosphorus (TP) by the use of CSPB could be reached 30%–35%, 35%–40%, 30%–40% respectively in the growing season (from March to October) and 5%–10%, 5%–15%, 7%–20% respectively in the winter (from November to February) when the detention time was 6 d. The relationships between the concentration of COD, TN, TP and the detention time fit the first-order kinetic equation well and the coefficients of determination ( ) were all above 0.9. The attenuation coefficients k of the kinetic equation were a function of the water temperature. When the water temperature was quite low or quite high, was not significantly changed with increasing or decreasing water temperature. While when the temperature was in a moderate range, an increase or decrease of water temperature would lead to a rapid increase or decrease in .
