Abstract

Razvoj industrijskih obratov povzroča povečano odvajanje tehnoloških odpadnih voda v komunalne sisteme. To predstavlja hudo obremenitev za okolje. Trajnostno ravnanje z vodami je tako neizbežno, zato je potrebno onesnažene odpadne vode obdelati v primernih čistilnih napravah. V diplomski nalogi je obravnavano področje fizikalno-kemijskega čiščenja tehnoloških odpadnih voda. Omenjeni postopki se uporabljajo za zagotovitev primernih mejnih vrednosti pri priključevanju na komunalne sisteme, ki se lahko končajo s komunalno čistilno napravo ali direktnim iztokom v vodotoke. Mejne vrednosti ureja EU zakonodaja s svojimi direktivami in Slovenska zakonodaja s svojimi zakonskimi akti. Podrobno so razloženi glavni fizikalno–kemijski postopki čiščenja tehnoloških odpadnih voda med katere spada koagulacija in flokulacija, adsorpcija, ionska izmenjava, membranska filtracija, kemično obarjanje, kemična oksidacija in napredni oksidacijski postopki. Prikazan je pregled največjih onesnaževalk v industriji in sektorji industrije, kjer so emisije ter količine tehnoloških odpadnih voda najvišje. Izračunane so količine odvajane odpadne vode in strošek, ki je posledica plačevanja okoljskih dajatev za posamezne industrije. Na koncu je predstavljeno še zagotavljanje mejnih vrednosti po BREF referenčnih dokumentih za določene industrije.

Secondary title: ǂThe ǂuse of physico-chemical processes in order to achieve the required parameters of industrial wastewater before connecting to the municipal system
Secondary abstract: The development of industrial facilities is causing increased discharge of industrial wastewater in municipal system. This represents a severe burden on the environment. Sustainable water management is so inevitable, that it is necessary to process polluted wastewater in a suitable treatment plant. The graduation thesis discusses an area of the physico-chemical treatment of industrial wastewater. Mentioned processes are used to ensure appropriate limit values for a connection to municipal systems that can end up with a municipal sewage treatment plant or direct effluent into watercourse. Limit values are regulated by EU laws with its directives and by Slovenian legislation with its legal acts. In the following thesis are explained the main physico–chemical wastewater treatment technology. This includes coagulation and flocculation, adsorption, ion exchange, membrane filtration, chemical precipitation, chemical oxidation and advanced oxidation processes. Author presents an overview of the largest emitters in the industry and industrial sectors, where are emissions and the amount of industrial wastewater the highest. Author also calculated the amount of discharged wastewater and the cost resulting from the payment of environmental charges for individual industry. At the end it is shown how limit values of emissions are ensured in the BREF reference documents for specific industries.
