2. füzet - Benedek Pál-Biró György-Farkas Péter-Literáthy Péter-Somlyódy László: Lebegőanyagokhoz kötődő mikroszennyezők transzportja és eltávolításuk lehetőségei
Lebegőanyaghoz kötődő mikroszennyezők 199 ной воде загрязняющие вещества. Условия в водоприемнике (реке) формируются под влиянием физических и физико-химических процессов. Из числа последных напр. многими специалистами исследовались явления перемешивания на рр Дунае и Шайо, однако значительное количество других факторов а также и взаимодействие этих факторов пока еще не разведано. Познание отдельных частных процессов таким образом имеет важное значение. Наряду с лабораторными и полевыми измерениями и накоплением различных данных следует заниматься также и разработкой математической постановки вопросов. Отсюда возникли частные модели, приведенные схематично и в данной работе. Суммированием этих частных моделей возможно достижение оптимального решения. * * * Transport aiul potential removal of trace pollutants adsorbed on suspended sediment by Dr. P. Benedek, Dr. Gij. Bíró, Dr. P. Farkas, Dr. P. Literáthy, Dr. L. Somlyódy The paper is concerned with the trace pollutants (and other pathogenic organisms), which tend to become adsorbed on the suspended matter present in the waste water and in the recipient stream, and to settle out on the bottom. The transport of such trace pollutants is examined by through the mathematical model approach, with the objective of finding the most efficient method of protecting the aquatic oecosystem, but especially oi preventing the trace pollutants from finding access to drinking water supplies. Closely related to the subject are the quality problems over the backwater reaches existing already and contemplated on the Tisza and Danube rivers. It is demonstrated that all methods of eliminating the trace pollutants and guaranteeing the desired quality of drinking water are known theoretically. Since, however, the economically feasible methods are inadequate the harmful methods should be removed preferably before the effluents are discharged into the recipients. Of the methods of waste water treatment the familiar biological treatment processes are primarily eligible for this purpose, but chemical treatment (clarification) to improve the efficiency of mechanical treatment (settling) may prove an economically attractive solution as well. Besides a better understanding on the technological methods, it is essential to determine the distribution within the recipient of the pollutants introduced in dissolved form and as precipitate with the treated effluent. The conditions prevailing in the recipient are the resultants of physical and physico-chemical processes. Of these the phenomenon of mixing has already been studied extensively, e.g. in connection with the Danube and the Sajó River, but a number of other effects and the interrelations thereof remain still to be cleared. Thorough research is thus needed on the various component processes. This should involve, in addition to laboratory and field measurements and analyses, and other data collection work, also the mathematical formulation of the processes. These result in the part-models described schematically in the paper, the combination of which is expected the optimal set of measures to be implemented. * * * Transport des niicropolluants liés à la matière on suspension et possibilités de leur élimination Pál Benedek, György Biró, Péter Farkas, Péter Literáthy et László Somlyódy L'étude traite des micropolluants (et de certains organismes pathogènes) disposés à lier aux matières en suspension des eaux usées et de la rivière et à se déposer au fond. 2*
