Water Pollution sources dissection has important guiding significance for drinking water sources protection. Focused on QingShuiHai valley, the research investigated water quality by uniform distribution sampling in the area in 2007∼2008, and analyzed pollution sources characteristics. The results showed that the concentration of Total Nitrogen (TN)(0.15–7.99 mg L−1) was 0.3 ∼ 15.98 times higher than...
Water and sediment samples, collected from Meiliang Bay in Taihu Lake, were employed to investigate the dynamic of phosphorus in water-sediment interface during the courses of proliferating, blooming and decaying of C. Reinhardtii under simulated conditions. Particulate phosphorus released from the decayed algae and sediment increased the availability of phosphorus to algae during the incubation....
This article reported the best conditions for plant sample microwave digestion using sulfuric acid-hydrogen peroxide (H2SO4 - H2O2) technology with the closed vessel microwave digestion system and pressure controlling part, established the spectrophotometry method to measure the total nitrogen and phosphorus in constructed wetland plants. The effects of the ratio of H2SO4 and H2O2 in this system and...
There is obvious effect for eutrophic wastewater treatment by constructing mangrove wetland, but mangrove plants grow under circumstances of a certain salinity, so this may influence the wastewater purification efficiency. Rhizophora stylosa, one of dominant mangrove species in South China, was used to construct simulated wetlands for eutrophic wastewater treatment. After 9 months irrigation to 8...
