The objective of the research project was the initial development of selected plant species useful for stabilising the surface ash dump. In the experiments, the effect of ash from the Termoelectric Power Plant „Siekierki” on the germination and growth of grass species was studied.
In the paper the authors shows the results of lysimetric investigation. The aims of the investigations were to get to know the essential doses and reactions of plants chosen for irrigation by leachate from solid waste disposal. The experiments were conducted on 68 lysimeters and 4 kinds of plants (Robinia pseudoacacia, Acer negundo, Sambucus nigra i Primus padus). The research were carried out on...
In the paper the authors analised the possibility of waste water utylisation front community Radiowo landfill for irrigation of reclamated areas. Chemical analisys indicates the level of chlorate in waste water up to 31 g/dm3. In order to be used in irrigation process waste water must be pre-treated to get the conductivity lower than 4 mS/cm. Technical and environmental analisys of landfill indicates...
The clay soils in the hydraulic barriers also act as an important medium for the attenuation of some contaminants due to sorption. The sorptivity of soils effect significanly the contaminant transport mechanism in landfill subsoils. In order to check the sorptivity of soils in two landfills, at Łuków and Marki, soil column tests were carried out. The test resuls of Łuków silty clay indicated that...
The paper presents the stability analysis of old large landfills of embankment type, localised nearby Warsaw, i.e. Radiowo. The reinforcement solytions applied on the landfill body as well as influence of leachote level in waste body were taken into account in stability analysis. The reiforcement method consist of retaining wall, berms, geogrids and tyre mattreses. The paper also presents shear strength...
In saturated clay soils with Iow values of hydraulic gradients and hydraulic conductivity lower than 1·10-9 m/s (geological barrier) the most important effect on the migration of leachate from landftlls has diffusion process. Therefore, prediction of contaminants migration should include both advection and diffusion models. The paper deals with application of the POLUTEv6 program for numerical analyzes...
