<p>PURPOSE:To make contribution to environmental maintenance and beautification without releasing contaminants to the environment by depositing refuse in a refuse treatment plant laid with waterproof sheets, putting specific capping sheets thereon to level off and admit rain water into the refuse and sending the refuse to a muddy water treatment plant. CONSTITUTION:The refuse 9 is deposited in the refuse treatment plant 1 which has a drain port 3 connected to the muddy water plant in the base, is formed with staircase-shaped flanks, has drain grooves 5, 6, 7 in the plane parts and is laid with the waterproof sheets 8 on the base and flanks. The capping sheets 10 formed by coating woven fabrics, non-woven fabrics, knitted fabrics or nets consisting of, a polyolefin with a photodecomposable polymer are put thereon to level off the rain water and to admit the water into the refuse 9. The muddy water is sent from the drain port 3 through a drain path 4 into the muddy water treatment plant. The capping sheets 10 put on the refuse initially exhibits waterproofness but the coating layers of the photodecomposable polymer decay as time passes by until fine holes open therein and the rain water penetrates uniformly into the refuse layers.</p> |
