Abstract
The invention discloses a sludge utilization method and application, and relates to the technical field of comprehensive utilization of natural water sludge. The sludge utilization method comprises the following steps: performing harmless treatment on sludge which meets the pollutant index requirements in GB/T 23486-2009 'Sludge Characters for Landscaping in Municipal Sewage Treatment Plant SludgeDisposal' and then using the sludge as greening soil, wherein the harmless treatment comprises plowing and curing the sludge stacked on green belt soil and added with a sludge fermentation microbialinoculum, and using the cured soil for planting landscaping plants. By using the method provided by the invention, the defects of complicated land use treatment process, single mode, and unremarkableenvironmental, economic and social benefits of the existing sludge are relieved; and according to the method provided by the invention, the sludge meeting indexes is used as soil for green belts, effective components in the sludge can be fully utilized, shore soil can be improved, the usage amount of chemical fertilizers and humus soil in garden planting can be reduced, the planting environment can be protected, non-point source pollution can be reduced, and sludge resource utilization can be realized.
