FIELD: household wastes purification. SUBSTANCE: apparatus is used to purify compost of solid household wastes from salts of heavy and non-ferrous metals and to provide increased quality of purification. Apparatus has initial compost lixiviater made as a tank with located in its bottom part outlet for purified compost ion-exchanging column to purify during lixiviation produced mixture from dissolved in it salts pipeline to feed the mixture from lixiviater into column and for return of purifying mixture into lixiviater and also mean to form pulp of initial compost with lixiviating liquid. Ion-exchanging column has mean for sorbent continuous feeding and discharging. EFFECT: increased quality of household wastes purification and extraction of heavy metals and non-ferrous metals. 2 dwg
