Organic wastewater treatment method |
| abstract |
(57) [PROBLEMS] To efficiently and economically treat an organic wastewater containing an anionic surfactant. SOLUTION: In the treatment of organic wastewater containing an anionic surfactant, after adding a cationic polymer coagulant, treated water obtained by further adding an inorganic coagulant is subjected to biological treatment. The treated water to which the inorganic flocculant has been added can be subjected to biological treatment as it is, but the addition of the inorganic flocculant causes agglomerates (fine flocs). It is preferable in terms of the efficiency of biological treatment. If an anionic polymer flocculant is added after the addition of the inorganic flocculant, a large floc is obtained and solid-liquid separation is facilitated. |
