Using modified food waste sludge activated sludge wastewater treatment for

The present invention discloses the use of a modified food waste sludge activated sludge and a preparation method for waste water treatment, food waste slag first ground to a particle size of 0.1mm, and then mixed with sewage sludge (by Kitchenware garbage waste and sewage sludge by dry weight dry weight mass ratio of 1: 1 to 1: 5), centrifuged, and then separating the solid part after drying, which was used in a microwave oven in a nitrogen atmosphere for 200 ~ 600 ℃ carbonization, carbonized material and then to 200 ~ 600 ℃ activated sludge prepared using modified food waste activated sludge. The present invention is the first use of a modified food waste sludge activated sludge, rational use of microwave technology, saving the energy required preparation of activated carbon, activated sludge only improves the ability to remove heavy metals in the waste water, waste and food waste solution was prepared activated carbon lower mechanical strength problems.
