Predlog sanacije odlagališča Globovnik : magistrsko delo št.: 105/II. VOI

Frank, Aljaž (author), Maček, Matej (mentor)

V Magistrskem delu obravnavamo problematiko odlagališča Globovnik, kjer je Tovarna organskih kislin (TOK) med leti 1958 in 1991 odlagala stranske produkte. Odlagališče je zaprto, a ni skladno s trenutnimi predpisi, brez urejenega monitoringa in z izcednimi vodami še vedno obremenjuje potok Trnovšek, reko Reko in Škocjanske jame. Na pobočju se še vedno odlagajo zemeljski in drugi odpadki. V teoretičnem delu smo predstavili problematiko odlagališča, identificirali možne sanacijske ukrepe ter predstavili postopek dimenzioniranja. V praktičnem delu smo določili ustrezne ukrepe za sanacijo Globovnika in prikazali potek dimenzioniranja v orodju Excel. Stabilnost brežin in varnostnega nasipa smo preverili tudi v orodju Slide. Predvideli smo stabilizacijo brežin z izvedbo ustreznih naklonov in berm, izvedbo drenažnega jarka za zajem zalednih vod, izvedbo pokrova z vgradnjo plinske drenaže, tesnilnega sloja, drenažnega geokompozita in vegetacijskega sloja z zatravitvijo ter ureditev odvodnjavanja pokrova. Predvidena je ureditev neustrezne meteorne kanalizacije zbirnega centra za odpadke in sanacija varnostnega nasipa. Pri sanacijskih ukrepih smo upoštevali zahteve Uredbe o odlagališčih odpadkov. S predlaganimi ureditvami predvidevamo zmanjšanje količine izcednih vod, kontrolirano razplinjevanje odpadkov in stabilno pobočje. Pričakujemo izboljšanje stanja potoka Trnovška in vplivnega območja odlagališča.

• Title: Remediation proposal for the Globovnik landfill : masterʼs thesis no.: 105/II. VOI

Abstract

The thesis addresses the issue of Globovnik landfill, where Tovarna organskih kislin (TOK) disposed by-products from 1958 to 1991. The lanfill is closed, non-compliant with regulations, non-monitored and still pollinates the Trnovšek stream, the Reka river and the Škocjan Caves system with leachate. Earth and other waste material is still being disposed on the lanfill slope. In the theoretical part, we presented the problem, identified possible remedial measures, and presented the dimensioning process. In the practical part, we determined the appropriate measures for Globovnik landfill remediation and presented the dimensioning process. The slope stability and the retention embankment were also analysed in Slide tool. We planned bank stabilization with the slope construction in suitable slope angles and berms, construction of a ditch for backwaters drainage, construction of a landfill cover with the gas drainage installation, a sealing layer, a drainage layer and a vegetation layer with grass. Drainage system construction of the cover is also planned. The storm sewerage of the waste collection centre is to be diverted. We also planned the restoration of a retention embankment. In remedial measures, we followed the requirements of the Decree on waste landfill. With the proposed measures, we envisage a reduction in the amount of leachate, a controlled degassing of the landfill and a stable slope. We expect an improvement in the Trnovšek stream condition and landfill area.
