| titleOfInvention | Wastewater coagulation treatment method |
| abstract | (57) [Summary] [Problem] To stabilize the flux of a membrane and reduce the frequency of chemical cleaning when performing a coagulation reaction in a coagulation tank by adding a coagulant to wastewater and then performing solid-liquid separation with a membrane separation device. . SOLUTION: While using an iron salt as a coagulant, a part of the concentrated liquid of the membrane separation device 3 is returned to the coagulation tank 1, and the SS concentration in the coagulation tank 1 becomes 0.5 to 6.5%. To do. [Effect] The cake resistance due to the sludge attached to the membrane surface of the membrane separation device is reduced. In addition, the amount of sludge adhering to the membrane surface is kept low, and the film can be easily removed and removed only by the backwashing operation. A decrease in the membrane flux of the membrane separation device is prevented, the flux is maintained stably, and the frequency of chemical cleaning is greatly reduced. |
