Study On The Effect Of A New Type Of High Efficient Biofilm And Aquatic Plant Combination Technology For The Purification Of Landscape Sewage

The eutrophication problem of city river is serious,which has been severely damaging the ecosystem.However most of the physical and chemical means can not solve the problem essencely,which will destruct the water environment and having a second prolution^[1],The main direction and methods of repairing the eutrophication water of lake is taking the method of Ecological remediation,Aquatic plants combination technology,and the combination of several or more methods adapting the rules of nature.In which,currently,the bioremediation is the core of Situ remediation of lake water quality in the word.The essay,combined with the state of eutrophication control strategy needs and relying on the Guangzhou collaborative innovation projects,make use of the new high carbon fiber composite materials of independently research by our subject on the high-biofilm technology.Then,the study filtered the group of the pioneer aquatic plants species apply on the construction of the ecosystem of the producers for the lake landscape water to carry out nitrogen and phosphorus removal research.To explore the water purification capacity of water quality and ecological restoration technology integration system.Which is aimed to provide technical reference value for the practical restoration engineering of lake water quality.Firstly,the study explored the best conditions of new efficient carbon membrane on water purification,by exploring the vary rules of total nitrogen,total phosphorus removal in the different aeration,different concentrations of water,different amount of chemical oxygen filling film in water content under the same condition.Secondly,through comparing the removal rate of total nitrogen and total phosphorus in different combinations of several aquatic plants and submerged plants,the study explored the the best pioneer plants groups for treating the eutrophication water.Finally,the study combined the new high carbon biological membrane technology with pioneer plant combination technology together,in the optimum purification conditions.then,compared the purification capacity of it with the single purification technology,in order to explore the best water purification technology.The results show that the combination of plastic carbon fiber has a good purification ability and low cost for CODcr,TN and TP in micro-polluted water.It is a cost-effective water purification material.The combination of aquatic plants is more suitable for eutrophic landscape water.The removal rates of TN and TP were 65.01%and80.29%,respectively.The removal rates of TN and TP were 90.01%and65.18%,respectively.The removal rates of TN and TP were 65.21%and80.29%respectively.The rate of purification of nitrogen and phosphorus in biofilm and aquatic plants was significantly higher than that of independent biofilm systems and aquatic plant systems,indicating that the combination of the two systems was The purification effect of water body is obviously higher than that of independent purification technology,which is of great significance to the management of lake water environment.
