In the article were presented, research methods and analysis of obtained research results the humidity distributions in ground under subsurface sewage di-sposal field from the physical model and the numerical model. To the research of the humidity of ground, in the laboratory was con-structed a physical model of the subsurface sewage disposal field which was an object of area investigates. [Kalenik 2002]. This model consisted of two independent frame systems: stand of the ground tank and the bed, after which the cart moved with installed appliances to measurements of the humidity of ground. Dimensions lump of ground being in a tank of ground are the following: length – 113 cm, height – 56 cm, breadth – 5 cm. To measurement humidity apply microwave appliance, acting in support about principle simultaneous measurement change amplitude and phase wave electromagnetic, which go through examine points of the profile ground. The applied method to research, she is fast, accurate and repeated, because she doesn't require structure was destroyed of investigated ground. To construction of the numerical model was used a software worked out through Z. Srokę and ...
The efficiency of sewage treatment in the ground bed under the subsurface sewage disposal field was tested in laboratory conditions using synthetic sewage. The ground bed was composed of mean sand and mean sand with assist layer with chalcedonite. The experiment determined the following indicators: suspended solids, BOD5, COD, total nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, total phosphorus and pH. In the sewage filtered through the ground bed of mean sand as well as through mean sand with assist layer with chalcedonite, increase in the values of nitrite nitrogen and pH was observed. The values other indicators of the treated sewage, was undergo a decrease. The suspended solids, BOD5, COD, total nitro-gen, total phosphorus of the treated sewage, are meeting obligatory standards. The ground bed with mean sand with assist layer with chalcedonite is characterized by a better effectiveness of sewage treatment. ...
