TREATMENT FOR SOLIDIFYING DISTILLED SLUDGE OF DRY CLEANER

PURPOSE:To permit pollution-free treatment by mixing lipophilically treated saw dust, clay and gypsum with distillation sludge under addition of water thereto at an ordinary temp., thereby converting the sludge to non-tacky dry solidified matter which is easy to handle. CONSTITUTION:1 part lipophilically treated saw dust, 0.39 part clay and 0.15 part gypsum are mixed with 1 part distillation sludge under addition of the water thereto at the ordinary temp. to form the solidified matter of the distillation sludge. As a result,the sludge can be converted to the non-tacky dry solidified matter which is easy to handle and, therefore, the easy throwing into a dust bin, etc., storage in a normal stock container, etc., are permitted. The so-called pollution-free treatment is possible. The effective utilization of the solidified matter to land reclamation and other applications is also possible after the hardness and heat resistance of the solidified matter, the confirmation of the non-emission of harmful eluates, etc., are investigated.
