THE INFLUENCE OF SEWAGE ON THE MARINE ENVIRONMENT

U završnome radu istraženi su čimbenici utjecaja sanitarnih otpadnih voda s brodova na more i morski okoliš. Analizirani su učinci crnih otpadnih voda na more i opisana su i navedena njihova svojstva. Objašnjen je i utjecaj otpadnih voda na priobalno more i čovjeka, te kako i zbog čega dolazi do eutrofikacije mora. Analizirani su pravni propisi i regulative koje se primjenjuju i donijete su u svrhu sprječavanja onečišćenja mora sanitarnim otpadnim vodama s brodova. Osim propisa EU-a i nacionalnih propisa RH posebna pozornost posvećena je i MARPOL 73/78 konvenciji s Prilogom IV koji je detaljno objašnjen i analiziran. Prikazana je i svrha i izgled međunarodne svjedodžbe o sprječavanju onečišćenja sanitarnim otpadnim vodama s brodova. Također navedeni su i uređaji na brodovima i postupci pročišćavanja crnih sanitarnih otpadnih voda te zbrinjavanje njihovih taloga na adekvatan način.In this final paper, influencing factors of ship sewage on the sea and marine environment have been explored. The effects of 'black' sewage waters on the sea are analyzed and described, together with their properties. The impacts of ship sewage on the coastal sea and humans are also explained, and how and why sea eutrophication occurs. The law and applied regulations have been analyzed. The purpose of these regulations is to prevent pollution of the ship sewage. In addition to EU and Croatian national regulations, special attention has been paid to the MARPOL 73/78 Convention - Annex IV, which has been explored and analyzed in detail. The purpose and appearance of an international certificate for the prevention of pollution from sewage from ships is also presented. Vessel’s equipment and purification procedures for sewage water and disposal of their deposits in an adequate manner are listed
