METHODS FOR TREATMENT OF WASTE ACTIVATED SLUDGE |
摘要 |
A process for treating waste primary or activated sludge solids that have been removed to a digester phase of the activated sludge process through the use of powdered natural ligno-cellulosic materials (PNLM) and/or powdered kenaf core (PKC). These materials help this process by: (a) thickening of primary and/or waste activated sludge through adsorption, attached growth and achieving closer proximity of organisms by stimulating reduction of their associated ECP substance; (b) enhancing endogenous reduction of primary and/or waste activated sludge by thickening (see above) and improving the ratio of available carbon to available nitrogen by delivering a continuing gradual release of sugar from degrading PNLM and/or PKC; (c) enhancing the speed of endogenous reduction of primary and/or waste activated sludge - through higher efficiencies (same processes as above); and (d) improving dewatering characteristics of wasted primary and/or wasted activated sludge solids (through reduction and breakdown of ECP materials and higher densification of solids). |
