Pregled metoda solidifikacije i stabilizacije opasnog otpada
Review of solidification and stabilization methods of hazardous waste
Institut za rudarstvo i metalurgiju, Bor, Srbija
Projekat: Uticaj rudarskog otpada iz RTB-a Bor na zagađenje vodotokova sa predlogom mera i postupaka za smanjenje štetnog dejstva na životnu sredinu (MPNTR - 37001)
Sažetak
U radu su prikazane metode stabilizacije i solidifikacije (S/S) opasnog otpada u zavisnosti od vrste otpada i sadržaja opasnih i štetnih komponenti, kao metoda predtretmana opasnog otpada pre odlaganja na deponiju. Prikazan je uticaj aditiva na efikasnost procesa S/S u zavisnosti od vrste otpada, uslova starenja produkta procesa S/S. Efikasnost S/S procesa merena je mobilnošću opasnih i štetnih komponenti nakon postupka solidifikacije/stabilizacije. Prikazana je i zastupljenost pojedinih postupaka stabilizacije i solidifikacije u procesu predtretmana opasnog otpada pre odlaganja. U radu su sistematizovani podaci vezani za procese stabilizacije i solidifikacije sa ciljem izbora najoptimalnijeg procesa za dalja istraživanja u oblasti smanjenja uticaja otpada nastalog kao posledica rudarskih aktivnosti na životnu sredinu.
Abstract
The paper presents stabilization and solidification (S/S) methods of hazardous waste, depending on the type of waste and content of hazardous and harmful components as the pretreatment method of hazardous waste prior to disposal on landfills. Also, the paper present the impact of selected additives and the aging conditions of the process product on the effectiveness of the S/S processes. Process efficiency was measured by mobility of hazardous and harmful components. Representation of some processes of stabilization and solidification in the pretreatment of hazardous waste prior to disposal in the world are shown. The aim of this paper is systematization of data and selection of optimal Solidification/ Stabilization process for further research in the field of reduction the impact of mining waste on the environment.
