FIELD: process engineering. ^ SUBSTANCE: invention relates to treatment of effluents and may be used in food, pharmaceutical and other industries. Proposed method comprises treatment of effluents by coagulants and flocculants and phase separation by flotation. In cleaning effluents of organic and suspended substances, effluents are fed in hydraulic pulse mode. Cleaned water is fed in said mode for preparation of coagulant solution and, further, for galvanic couple. Said mode is realised with frequency of 0.1-2.5 Hz and amplitude of 0.001-0.05 m. Portion of cleaned water is fed to saturator to be divided into two flows, one to be fed to pressure flotation cell inlet while another one is fed for mixing with prepared solution of coagulant. ^ EFFECT: higher efficiency of cleaning. ^ 4 cl, 1 dwg, 2 tbl, 2 ex |
