Abstract

Kompostne vode, ki nastajajo kot stranski produkt pri kompostiranju, predstavljajo veliko nevarnost za okolje, saj vsebujejo veliko organskih in anorganskih snovi. Namen diplomske naloge je bil odstraniti čimveč organskih snovi iz kompostne vode z minimalnim dodatkom kemikalij, s postopkom koagulacije ter izmeriti razliko vsebnosti neraztopljenih in raztopljenih snovi po obdelavi. Koagulacijsko/flokulacijski sistem lahko uporabljamo kot predčiščenje pred mikro- ali ultrafiltracijo, ali pa kot kemijsko čiščenje kompostne vode. V laboratoriju smo opravili vrsto Jar-testov, s katerimi smo želeli znižati vsebnost koloidnih in suspendiranih snovi v kompostni vodi, ki v nadaljnih postopkih čiščenja najbolj mašijo membrane. Določevali smo minimalno količino flokuliranega sredstva, ki je potrebno za optimalno znižanje parametrov kompostne vode. Raziskave so pokazale, da smo v kompostni vodi največje znižanje organskih snovi dosegli s kombinacijo 10 mL Kemiclar PAC in 1 mL Magnafloca 10 v 1 L vzorca. Motnost se je znižala iz 1455 NTU na 234 NTU, absorbanca pri 254 nm pa iz 40,47 na 9,38.

Secondary title:	Reserch of Solids Content in Flocculated Compost Leachate
Secondary abstract:	Compost leachate, a by-product of composting, contains lots of organic and inorganic substances and is considered a major threat to the environment. The research purpose of this diploma thesis was to remove as much organic substances from the compost leachate by adding only minimal amount of chemicals during coagulation process and measured the difference of the content of undissolved and dissolved solids after the treatment. The coagulation/flocculating system is used as a pre-treatment prior to micro- or ultrafiltration, or as a chemical treatment of compost leachate. In a laboratory, a series of Jar testing procedures were conducted in order to lower the levels of colloidal and suspended substances in the compost leachate, that usually clog the membranes in a further cleaning processes. Our objective was to determine the minimum amount of the flocculated agent needed to achieve optimal reduction of parameters that indicate the level of water pollution. Research showed that the highest reduction of organic substances in compost leachate has been reached by using 10 mL Kemiclar PAC and 1 mL Magnafloc 10 in 1 L sample. Opacity values reduced from 1455 NTU to 234 NTU, absorption at 254 nm reduced from 40,47 to 9,38.
