The present work evaluates whether ammonium and nitrate ions become linked with diluted olive oil mill wastewaters (OOMW). From a laboratory experiment it was concluded that the ammonium ion linked with OOMW in the presence of carbonates or hydroxides and OOMW could block up to a third of the present ammonium-N ion. On the other hand, OOMW are capable of joining with the nitrate ion, in a sulphuric diluted medium at room temperature, retaining up to 80% of nitrate-N. These complexes could be useful for recycling OOMW as new OOMW-N fertilizers. In soils treated with OOMW-N fertilizers, the nitrate-N emissions were reduced by 90% for two months. So, inorganic-N fertilizers mixed with OOMW could produce new organic fertilizers with a higher efficiency index for N.
本研究评估了铵和硝酸盐离子是否与稀释的橄榄油厂废水（OOMW）结合。从实验室实验中得出结论，在存在碳酸盐或氢氧化物的情况下，铵离子与 OOMW 结合，并且 OOMW 可以阻止多达三分之一的现有铵-N 离子。另一方面，OOMW 能够在室温下的稀硫酸介质中与硝酸盐离子结合，保留多达 80%的硝酸盐-N。这些配合物可用于回收 OOMW 作为新型 OOMW-N 肥料。在施用 OOMW-N 肥料的土壤中，两个月内硝酸盐-N 的排放量减少了 90%。因此，将无机-N 肥料与 OOMW 混合可以生产出具有更高 N 效率指数的新型有机肥料。
