<p>FIELD: waste disposal. SUBSTANCE: invention relates to waste water treatment and production of high-quality environmentally safe humus. In order to increase productivity and product quality and also to separate ill and healthy worms, solid waste, prior to be crushed, is washed by water and, when crushed, is mixed with leaven, fed into thermal reactor and into bin biofilter. Remaining worms together with cocoons and coprolites are directed into tower filter where they are separated. Worms are further directed into collection tank. Cocoons into incubators, and coprolites are passed over flotator, drying apparatus, and then are collected as humus in final-produce tank. Installation contains in-series connected thermal reactor 5, bin biofilter 10, tower filter 11, flotator 16, final-produce tank 23, worm-collection tank 24, and incubator 25. Bin biofilter is made in the form of chamber 7 with perforated pipes 6 and 8 on its bottom to feed paste and air, and, above the surface paste, double louvered base 9 of bin 10 is disposed to provide transferring worms into bin 10, its volume filled with loosely placed material accommodating worms, cocoons and coprolites. EFFECT: increased productivity and q of product. 2 cl, 4 dwgd</p> |
