Uporaba membranskih bioreaktrojev na komunalnih čistilnih napravah : diplomska naloga

Maučec, Miha (author), Drev, Darko (mentor), Krzyk, Mario (co-mentor)

V diplomski nalogi je predstavljena uporaba membranskih bioreaktorjev na komunalnih čistilnih napravah. V industriji se takšni sistemi uporabljajo že dalj časa, saj prispevajo k boljšemu čiščenju odpadnih in tehnoloških voda. Z vse strožjimi standardi o izpustih iz čistilnih naprav se je začela uporaba membranskih bioreaktorjev tudi na komunalnih čistilnih napravah. Cilj naloge je bil opisati postopek čiščenja odpadnih voda z membranskimi bioreaktorji, ter predstaviti, prednosti in slabosti teh sistemov. Podjetja so k razvoju membranskih bioreaktorjev pristopila na različne načine, tako je prišlo do nastanka več vrst sistemov membran, različnih materialov membran, ter postopkov v samem delovanju membranskih bioreaktorjev. Tako so predstaviljeni najpogosteje uporabljeni sistemi, kateri so že dobro preverjeni za uporabo na komunalnih čistilnih napravah, saj so v uporabi že vrsto let. Iz preučevanja literature je bilo razvidno, da uporaba membranskih bioreaktorjev na komunalnih čistilnih napravah še ima določen pomankljivosti. Predvsem stroškovno gledano še niso izenačeni z običajnimi biološkimi čistilnimi napravami, kar pa je posledica, menjavanja membran, ter neuveljavljenosti membranskih bioreaktorjev, kar posledično zvišuje ceno postavitve sistema. Določene pomankljivosti membranskih bioreaktorjev so tudi pri vzdrževanju oziroma čiščenju membrane.

• Title: Usage of membrane bioreactors for municipal wastewater treatment plants : graduation thesis

Abstract

We wanted to present the usage of membrane bioreactors for municipal wastewater treatment plants. In industries such systems are widely spread contributing to improve wastewater treatment. With increasing standards on discharges from wastewater treatment plants began usage of membrane bioreactors at municipal treatment plants. The aim of the thesis was to describe the process of wastewater treatment with membrane bioreactors and to present advantages and disadvantages of these systems. Companies that produce membrane bioreactors have different ways of approaching to development. So there has been the emergence of several types of membrane systems, materials and procedures in the proper functioning of membrane bioreactors. We have presented the most commonly used systems, which are already well proven for usage for municipal wastewater treatment plants, since they have been in operation for several years. By studying the literature it showed that the usage of membrane bioreactors for municipal wastewater treatment plants still has some drawbacks. Particularly the operating costs are higher than by conventional biological wastewater treatment plants, which is result of membrane exchange. Since the membrane bioreactors are not commonly used at this type of treatment plants the costs of installing the system are therefore also higher. Some of setbacks of membrane bioreactors can be found in intense maintance and cleaning of the membranes.
