Abstract
Plants of surface wastewater purification by using natural biological processes mainly consist of the following design elements: water-supply and drainage systems, sedimentation chamber, filtration dams filled with grain material, areas of flow biochemical treatment due to the life process of higher water plants. To improve the functional characteristics of filtration dam and technology of its construction, the invention proposes to erect a dam of the open porous thermoplastic concrete blocks (LV 13707) or of the gabions by filling them with lumpy composite material of open porous composite material formed by fractionated granular filler and the thermoplastic binder or of gabions filled with a lumpy composite material formed by the filler-minced cellulose containing materials (LV 12344) with the thermoplastic binder. The afore mentioned materials inhere all necessary functional and operational characteristics: strength, filtration characteristics, frost resistance, oil receptivity, sorption and coalescence characteristics.
