20.500.12556/DKUM-74892 Testiranje delovanja naprave za čiščenje vode, sproščene pri pranju škropilnice Testing the Purificaton Device for Water Released in Sprayer Cleaning V letih 2017, 2018 in 2019 smo testirali delovanje naprave, ki je bila zgrajena na živinorejski kmetiji kot del programa vodenega s strani podjetja BASF. Obrat za čiščenje kontaminirane vode spada med hibridne sisteme Biobed–Biofilter. Fitofarmacevtska sredstva (FFS) onesnažujejo vodo, ki odteka med pranjem razpršilca/škropilnice. Ta voda se zbira v rezervoarju in se skozi vso leto pretaka skozi posode, v katerih je mešanica zemlje, šote in slame. V mešanici poteka mikrobna razgradnja aktivnih snovi (AS), kjer voda izhlapi iz površine zmesi. Analizirali smo dinamiko dekompozicije 50 AS, prostornino tedenskega izhlapevanja vode in opravili izračune kapacitete naprave glede na število ciklov pranja razpršilcev, ki jih je možno izvesti letno. Razčlenitev AS je bila dokaj počasna, saj je bila pri večini AS ugotovljena stopnja razpadanja med 50 in 70% na leto. Predstavljeni so šibki in močni tehnični vidiki naprave. During the years 2017, 2018 and 2019 we tested the performance of a device which was built on a livestock farm as a part of a BASF Company stewardship program. The plant is classified as the hybrid system Biobed–Biofilter. Plant protection products (PPP) contaminate water which is released during sprayer washing. This water is collecting in a tank and circles throughout the year through contaioners which are filled with a mixture of soil, peat and straw. In the mixture it's running microbial decomposition of the pesticide active substances (AS). The water evaporates from the surface of the mixture. We analized the dynamics of the decomposition of 50 AS, the volume of weekly water evaporation and performed calculations of the capacity od the device according to the number of sprayer washing cycles, that can be performed annually. The breakdown AS was fairly slow, because the established rate of decay for most AS was between 50 and 70% per year. Presented are weak and strong technical aspects of the device. čistilna naprava pesticidi škropilnice pranje purification device pesticides sprayers cleaning true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-09-11 16:41:37 2019-10-18 09:00:33 2022-08-09 09:41:23 2019-10-19 03:13:26 2019 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:SMYW7K0O VS_Jelen_Anja_2019.pdf VS_Jelen_Anja_2019.pdf 1 DE9617A8C8D10D2132A8A386B7847171 c2845956ea022a14a4f069c83f7ee2ad66f0a223fbf8154c61c71711e62a42e3 0da181c8-7c11-11eb-bb7a-00155d0001ca 20.500.12556/dkum/512fb62a-c587-464e-b966-abcfaf22a86d https://dk.um.si/Dokument.php?lang=slv&id=138721 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
