Sancha lake is the second largest lake in Sichuan Province, the factors of affecting eutrophication are not only point pollution source, but also non-point pollution source. The results of the investigation show: drawing water is 50% of total phosphorus contribution, cage culture is 10.44%, 39.21% of precipitation and surface runoff, sewage is 0.35%, although the drawing water is 50% of the total...
Three aquatic macrophytes including Rumex dentatus Linn., Ranunculus sceleratus Linn. and Rorippa palustris Leyss (Bess.) were selected as materials for investigating their purifiction efficiencies by analyzing pH value, total nitrogen (TN), total phosphorus (TP) and chemical oxygen demand (CODCr) of the eutrophicated water from Jialu river. The results indicated that the three species had different...
Recently, a new-style agricultural industry, pollution-purifying agriculture (PPA) or contamination-purifying agriculture (CPA), is proposed and carried out in China. Combination and development from established on the base of environmental engineering technological principles and methods, PPA focus on the eutrophication removing and aquatic ecosystem remediation by using the advanced constructed...
Dianchi Lake, one of the most eutrophication freshwater lakes in china, has been under severely eutrophic condition since 1970s. This study investigated the concentrations of total phosphorus (TP), soluble reactive phosphorus (SRP) in the overlying water and the interstitial water in water-sediment interface through analysis of the water samples collected from 37 sites around Dianchi Lake to obtain...
As a major part of the Dianchi Lake, the Caohai Lake is in a serious eutrophication situation, which is imminent for pollution treatment. An improved floating bed, which called combined packing with emergent aquatic plants canna indica, submerged aquatic plants Hydrilla verticillata and aeration device, was used to purify the water taken from the Caohai Lake. Compared with the traditional floating...
The pollutants, which were brought by the living and producing of the village in Lake Baiyangdian, would have some effects on surrounding water quality. During May 2009 to March 2010, the research evaluated and analyzed the eutrophication state of five selected sampling points. Experimental result indicated that, the water around the village appeared eutrophication phenomenon overall, fish and poultry...
