Summary:PROBLEM TO BE SOLVED: To provide a method and an apparatus for biological wastewater treatment, allowing a high load operation in a biological treatment tank. SOLUTION: Since ash generated by the combustion of biomass such as EFB (Empty Fruit Bunch), Fiber or PKS (Palm Kernel Shell) contains a trace nutrient element which is scarce in organic wastewater such as POME (Palm Oil Mill Effluent) and which is required for biological treatment such as methane fermentation treatment, the organic wastewater is supplemented with the trace nutrient element by adding the ash to the organic wastewater, and consequently, the high load operation is allowed in the biological treatment tank such as a methane fermentation tank 4.
