Method for building up defined phosphate deposits from waste phosphates

摘要: For simultaneous elimination and fixation of phosphates from phosphate burdened aqueous liquids like sewage water a deposit space is formed by soil matrix containing iron and/or aluminum. The defined layers poor hydraulic conductivity along its sides at the bottom thereof Limnophytae species Phragmites, Typha, Carex, Glyceria, Eleocharis, Juncus, Iris pseudacorus, versicolor, Schoenoplectus, Phalaris, Arundo are planted in to form reactive penetrated root systems said plants. liquid introduced one side leaves same with content 0.1 mg/l range flow rates 10-3 10-2 m per sec. Valuable deposits useful as arable land not requiring any fertilizer or recoverable obtained amounts depending on capacity time period fixation.
