沉水植物分解对人工湿地水质的影响
Impact from submerged plant decomposition on water quality in artificial wetland
摘要
Abstract
In order to study the continuous impacts from the decompositions of the main submerged plants,such as Ceratophyl lumdemersum,Myriophyllum spicatum,Hydrillaverticillata and Potamogetoncrispus,in the artificial wetland on the water quali ty,the indoor decomposition barreled simulations are made.For comparing the impacts from the decompositions with and without plant litters,two different treatments are made on water body,i.e.a set of water sample without plant litter and each of all the other sets of water samples with one of the plant litters,and then three barreled experiments are made for each treatment,so as to monitor the indexes of temperature,pH,dissolved oxygen,total dissolved solids,electrical conductivity,etc.The result shows that the indexes of the water body are to be changed along with the decompositions of the four plant litters,for which pH and dissolved oxygen present the trends of lowering at first and then rising,while both dissolved oxygen and electrical conductivity present the trends of rising at first and then keeping a certain level.Impacts from different submerged plant litters on water body are different,and then the sequence of the impacts from the four plant litters on total dissolved solids,electrical conductivity is Ceratophyllumdemersum,Myriophyllum spicatum,Hydrillaverticillata and Potamogetoncrispus.This study result has a reference value for making the tactic of the management and utilization of aquatic plant.关键词
