    摘要： Methods for removing e.g. odor-causing components from liquid sludge, and, in one embodiment, a process for sludge deodorization which includes pretreating the sludge to gasify certain components, reducing the size of solids in the sludge, feeding the thus treated sludge tea stripping tower and therein removing in a stripping gas undesirable components from a thin film of the sludge on the interior tower wall. Preferably, the treated sludge is dewatered. Products from the tower may be recycled for further treatment until a desired odor level is achieved or discharged from the process. The process may be batch or batch-wise continuous.

    摘要： Processes are disclosed for treating materials such as waste material, wastewater, and sludge, particularly waste activated sludge (WAS). In one aspect a process according to the present invention includes denaturing, acidifying and degassing incoming WAS while venting gases produced, preferably to a vent treatment system; feeding the resulting denatured WAS to a reactor into which are fed steam and oxygen, the steam discontinued once the reaction becomes autothermal; venting hot gases from the reactor back to the degassing step, to heat recovery or to a reactor, e.g. a sequencing batch reactor; and cooling and neutralizing the reactor product. Batch, semi-continuous, and batch sequencing methods are disclosed.

    摘要： Methods for the incineration of waste gas containing oxygen are disclosed which, in one aspect, have a combustion chamber with a high intensity, stable burner jet projecting therein and a backmixing zone in which are mixed burner fuel and waste gasses flowing into the chamber via a waste gas flow line. As desired additional fuel, e.g. fuel such as methane added to vitiated air, may be introduced into the chamber. Preferably, the heat content of the supplemental fuel is adjusted to control temperature in the combustion chamber while a stable combustion zone is provided. In one aspect flue gas from the chamber flows to a heat recovery apparatus to recover heat value of the flue gas.
