| titleOfInvention | Wastewater treatment method |
| abstract | The present invention provides a wastewater treatment method capable of improving wastewater treatment performance by preventing a decrease in flux of a separation membrane. SOLUTION: A process for insolubilizing heavy metals contained in waste water, and a waste water containing insolubilized heavy metals are allowed to flow into a membrane separation tank, and membrane separation is performed using a separation membrane provided in the membrane separation tank. A wastewater treatment method comprising a step of separating waste sludge and filtered water, the step of discharging sludge from within the membrane separation tank, and in the step of discharging sludge, the SS concentration after sludge discharge is The sludge discharge amount is adjusted so as to be 60% or more of the preset average SS concentration.
