İzmir'de bulunan bir hastanenin atıksu ve atıklarının yönetiminde sıfır deşarj yaklaşımı

In this study, the solid and the liquid wastes produced from a hospital and the present waste management procedures was investigated and some novel waste management techniques were determined to treat the solid, liquid waste and wastewaters. The solid wastes should be collected in special coloured bags, they should be labelled and should be stored in special storage area, and should be disposed by the licensed companies according to Waste Management Regulation. The application of the waste separation at the source throughout the hospital decreases the waste disposal fees. The management of hazardous liquid wastes coming from the hospital should be handled as proposed by TÜBİTAK. In Turkey, the hospital wastewaters are not treated and they are released directly to the municipal sewage channel system. Since the hospital wastewater contains some micropollutants such as antibiotics, analgesics, anesthetic chemicals, anti-inflammatories; these organics inhibit the bacteria growth in biologic treatment. Therefore, in this study, some novel-advanced treatment methods to remove the hospital wastewaters were presented. An advanced treatment method contact Anoxic/Aerobic sequential Membrane Bioreactor (AAMBR) system for the treatment of hospital wastewater was suggested and relevant design parameters were calculated. Since the contact AAMBR effluent water quality is very high, therefore, it is considered to use as irrigation purpose. Effluent water characteristics were examined according to irrigation water legislation and the quality of the treated hospital water was considered suitable for use as irrigation water. Reuse of treated water is very important both in terms of protecting natural resources by providing economic benefits.
