Abstract

Voda je vir življenja in nosilec vseh bioloških procesov, ki se odvijajo na našem planetu. Nekatera škodljiva sredstva povzročajo prekomerno razraščanje alg, ki onemogočajo svetlobi, da prodre v vodo. Barvila v vodi (predvsem temna) onemogočajo prodor svetlobe v vodo, kar povzroči, da koristne bakterije ne morejo opravljati svojega dela – čiščenja odpadne vode. Skoraj vsa sintetična barvila se razgrajujejo zelo počasi, kar je ekološko nezdravo in okoljsko nevarno. V diplomskem delu smo z adsorpcijo na zeolit ter granulirano oglje prikazali razbarvanje vod. Obarvanost se lahko pojavi na odpadnih vodah, ki pridejo v čistilno napravo Rajnkovec, Rogaška Slatina. Z adsorpcijo smo želeli zmanjšati vrednosti parametrov, ki so lahko občasno tudi preseženi. Najučinkovitejše razbarvanje smo dosegli po adsorpciji na granulirano aktivno oglje. V diplomsko nalogo pa smo vključili tudi shematski prikaz alarmnega sistema. Če pride do vdora padavinskih voda, lahko z njim to preprečimo oziroma hitreje odpravimo.

Secondary title:	Decoloration of water from biological treatment plant and proposition for water sources protection against intrusion of rainwater
Secondary abstract:	Water is the source of life and the carrier of all biological processes that take place on our planet. Some harmful agents cause excessive overgrowth of algaes, that are preventing light to penetrate the water. The dyes in water (especially dark ones) are preventing penetration of light to the water and consequently, benefitial bacterias can not do their work – clean waste water. In this diploma thesis we have displayed the discoloration of water by adsorbtion on zeolite and granulated chorcoal. Coloration can appear on the waste wathers, that come to waste water treatment plant Rajnkovec, Rogaška Slatina. With adsorption we wanted to decrease the values of parameters that could sometimes be exceeded. We have reached the most efficient discoloration after adsorption on granulated active charcoal. In this diploma thesis we have also included shematic display of alarm system. If rainwater intrusion occurs, we can use the system to prevent or eliminate it more quickly.
