| Sažetak | Ovaj rad opisuje vodu u prirodi u stalnom kruženju a koja je neophodna u mnoge svrhe, kao što su: piće, sanitarne svrhe, poljoprivredu, industriju, urbani razvoj i dr. Drastičnim povećanjem broja stanovnika, porastom industrijske proizvodnje, te prometa, sve je manje čistih rijeka i pitke, slatke vode za piće. U mnogim dijelovima svijeta prisutna je nestašica, postupno uništavanje i povećano zagađivanje slatkovodnih izvora. Onečišćavanje voda, mora, jezera, te za naš život tako važnih rijeka, predstavlja najstariji i najopsežniji oblik zagađivanja čovjekove okoline. Također u ovom završnom radu obrađena je problematika otpadnih voda sa naglaskom na izvore zagađivanja voda, pročišćavanje zagađenih otpadnih voda, zakonsku regulativu, Navedene su i karakteristike otpadnih voda, njihova podjela i primjeri tretiranja industrijskih i komunalnih otpadnih voda, te neki od najznačajnijih zakona, pravilnika i uredbi vezanih za zaštitu voda i zaštitu okoliša. |
| Sažetak (engleski) | This paper describes constantly circulating water in nature which is necessary for many purposes, such as: for drinking, sanitation purposes, agriculture, industry, urban development, etc. Due to drastic population, industrial production, and traffic growth, the number of clean rivers and the volume of drinking freshwater are decreasing. Many parts of the world face drinking water shortage, gradual destruction, and increased pollution of freshwater sources. The pollution of water, seas, lakes, and rivers, which are very significant in our lives, represents the oldest and the most extensive form of pollution of the human environment. This final paper also addresses the issue of waste water and focuses on the sources of water pollution, polluted waste water purification, and legislation. It includes the characteristics of waste waters, their classification, and examples of industrial and communal waste water treatment, as well as some of the most important laws, policies, and regulations related to water protection and environmental protection. |
