APPARATUS FOR PURIFYING SEWAGE WATER

摘要

FIELD: chemistry. ^ SUBSTANCE: sewage water is fed into an electrofloatation apparatus. The electrofloatation apparatus consists of a single-chamber housing 1 and insoluble electrodes 2. There is a magnet 5 at the bottom 4 of the housing 1. During electrofloatation, foam 13 and dirt 22 is formed and hydrogen 16 is released at the cathode. Foam 13 is sucked through a socket pipe 10 into a cyclone filter 12. Hydrogen 16 is removed through a pipe 15. Dirt is removed from the cyclone filter 12 by Archimedes' screw 18. The air mixture from the cyclone filter 12 is pumped by a pump 23 through a pipe 11 into the chamber 20 of the housing, in which carbon dioxide gas 24 is also fed. ^ EFFECT: invention enables to purify waste water and utilise electrofloatation products. ^ 1 dwg
