A Experimental Study on the Removal the Nitrogen Phosphorus of Eutrophication-water and Restraint of Algae by Alternanthera Philoxeroides

Has studied the Alternanthera Philoxeroides to the ultra eutrophication water body, eutrophication water body total nitrogen total phosphorus elimination ability and damps the algae effect..Had ended after the experimental cycle,the Alter- nanthera Philoxeroides processes 3 high to the total nitrogen total phosphorus average elimination speed with the average bio- logical mensuration computation,Respectively is 79.2 mg/kg*d,23.7 mg/kg*d;But to total nitrogen total phosphorus relative elimi- nation rate processing 5 highest,Respectively is 91.6% and 95.1%;Simultaneously studied the Alternanthera Philoxeroides growth quantity,has damped the algae effect,in vivo total nitrogen total phosphorus content,Further explored the Alternanthera Philoxe- roides to purify in the water quality the application.
