Landfill compost with sludge dryer

Due to the inadequate management of sanitary landfills, secondary pollution is likely to occur. In addition, the country has formulated relevant standards and technical policies for sanitary landfills. The moisture content of the mixed landfill of printing and dyeing sludge is specified to be less than 60%, and the transverse shear is greater than 25KN/ Square meters. In fact, the moisture content of the dehydrated cake is greater than 80%, and the direct landfill treatment has been restricted by the current regulations, and direct landfill is not allowed. The state has increased law enforcement in this regard. In composting treatment, organic sludge contains nitrogen, phosphorus, and potassium, which are essential fertilizer components for crop growth. The crude protein or globulin in the activated sludge is a good soil conditioner. The sludge has stable properties and can be used as a fertilizer with agricultural use value.
