For their primary treatment, in this paper, ten coagulants were used. The first examination was the so-called Jar-Test, by means of which the most potent agents i.e. Zetag 7635, Magnasol 5389 and PIX-113, respectively, were selected. Then, the efficiency of these coagulants in waste treatment was studied. Three main parameters: COD, amounts of hexane extractive substances and SO42-concentration were detenninate. It was found that the aforementioned coagulants reduced the COD parameter, as well as the amounts of dispersive greases and free fatty acids significantly. Unfortunately, the problem of the removal of sulfates remains still unsolved.

Zeolite-coal adsorbents were prepared from a mixture of gas-coking coal, type 34.2, from the 'Anna' mine and 'Maria' kaolin, from the Nowogrodziec mine in a mass ratio 1:1 during carbonisation, activation and base treatment processes. Behaviour of raw materials, i.e. coal and kaolin, was studied in analogous conditions, in order to explain processes taking place during co-carbonization, co-activation and co-crystallization. Properties and structure of coal chars, activation products and adsorbents, as well as, their usefulness for wastes treatment were onvestigated. The kaolin-coal mixture can be used for production of highly active zeolite-coal adsorbents useful for wastes treatment and air detoxification.

Badano adsorbenty zeolitowo-węglowe z mieszaniny (1:1) z węgla gazowo-koksowego typ 34.2 z kopalni 'Anna' i kaolinu z kopalni 'Maria' w Nowogrodźcu. Mieszaninę oraz surowce poddawano procesom karbonizacji, aktywacji i obróbce alkaliami. Badano właściwości i strukturę porowatą adsorbentów. Wykazano ich przydatność w procesach oczyszczania ścieków i detoksykacji powietrza.

The study concentrated on usefulness of waste materials from Petrochemia Płock wastes treatment plant. Waste materials used in invetigations included sludge and ashes formed after burning of sludge in fluidised-bed furnaces. These materials were used for production of adsorbents. The adsorbent's quality was tested in adsorption and adsorption-coagulation processes of treatment of wastes from CPN and model sewage.

PL

Badano przydatność materiałów odpadowych z oczyszczalni ścieków w Petrochemii Płock tj. osadów ściekowych i popiołów z ich spalania w piecach fluidalnych jako surowców do otrzymywania adsorbentów. Jakość ich oceniano w procesach adsorpcyjnych i adsorpcyjno-koagilacyjnych oczyszczania ścieków z CPN-u i ścieków modelowych.
