Abstract

V bolnišnicah je higiena ključnega pomena, zato se v njihovih pralnicah dnevno opere več ton umazanega perila. Zaradi večjih količin dodanih pralnih sredstev, prisotnih organskih in anorganskih snovi ter drugih nečistoč, je treba odpadno vodo pred odvajanjem v vodotoke ali kanalizacijo, ustrezno očistiti. V diplomskem delu smo z adsorpcijo na zeolita ZAG–CWK in ZAG–4A–2–3 ter granulirano aktivno oglje, čistili odpadno vodo iz pralnice Splošne bolnišnice Celje. Z metodo adsorpcije smo želeli z adsorbenti zmanjšati vrednosti občasno preseženih parametrov (pH, električna prevodnost, motnost, KPK, vsebnost tenzidov). Vpliv vzorcev odpadnih vod pred in po adsorpciji smo raziskali tudi s pomočjo čebulnega testa. Najučinkovitejše očiščenje odpadne vode in posledično znižanje vrednosti parametrov smo dosegli po adsorpciji na granulirano aktivno oglje.

Secondary abstract:	In hospitals, hygiene is of key importance, therefore their laundry services launder several tons of dirty linen every day. Due to large amounts of added laundry detergents, presence of organic and inorganic substances and other impurities, the waste water must be properly treated before it is discharged into watercourses or sewage systems. In the diploma thesis, we treated waste water from the General Hospital Celje laundry service with adsorption on zeolites ZAG–CWK and ZAG–4A–2–3 and granular activated charcoal. By using adsorbents, we wanted to reduce values of occasionally exceeded parameters (pH, electrical conductivity, turbidity, COD, tensides content) with the adsorption method. Waste water samples before and after adsorption were also examined with an onion test. Most efficient waste water treatment and, consequently, the reduction of parameters was achieved with adsorption on granular activated charcoal.
