| 摘要 |
The invention relates to plants for sewage treatment, in particular for separation by ultrafiltration of water-oil emulsions obtained as a result of metal degreasing, cooling, working with the view of elaborating closed technological cycles of water utilization. The plant, according to the invention, consists of a circulating pump (1), a system of tubular ultrafilters (22), fixed onto a frame (3), a collector (4) and a capacity (5) for filtrate, a separator (6) equipped with pipes for concentrate feeding (7), for aqueous phase outlet (8) into the capacity of the recirculation system (9), coupled with the pump (1), and for used adsorbent outlet (12). At the same time, the separator (6) is additionally equipped with a system for introduction of the magnetosusceptible adsorbent (19), consisting of a capacity (10) and a pipe-line (11), coupled with the pipe for concentrate feeding (7), made with the possibility of concentrate tangential infeed into the separator (6), a bunker (16), a rotary drum (13) with electric drive (14), made of diamagnetic material, inside which there are fixed oblique blades (17) and there is placed a spherical magnetic charge (18). After oil adsorption, the magnetosusceptible adsorbent (19) is removed with the help of a scraper (15) from the surface of the drum (13) into the adsorbent outlet pipe (12). The result of the invention consists in increasing the efficiency of water-oil emulsion separation.
