摘要： The present invention relates to method for recycling alkaline waste water from a stainless steel slag treatment process wherein stainless steel slag is brought into contact with water thereby producing said waste water, which waste water contains heavy metals, including at least chromium, and has a pH of at least 12. The waste water is recycled by using it for treating an alkaline granular carbonatable material, which contains aluminium metal, in order to oxidise the aluminium metal contained therein. This material is in particular municipal waste incinerator bottom ash which can, after the treatment of the present invention, safely be used as fine or coarse aggregate in bonded applications such as concrete, mortar and asphalt. During the treatment with the alkaline waste water, hydrogen gas is produced which is captured and used to produce energy by means of a cogeneration device.

摘要： A method for recycling aluminium slags, comprising the steps of supplying aluminium slags, releasing aluminium-containing parts from the slags using a first crushing device in which the slags are crushed to form fractions, filtering the fractions using a first screening device to form at least a first and second part-stream, and passing at least the first part-stream along an eddy current separator for separating the aluminium-containing parts from the first part- stream. At least the first part-stream is passed along an eddy current separator which is driven at a rotary speed of less than 1000 rpm. The parts which remain downstream of this eddy current separator at the rotary speed of less than 1000 rpm are returned to a crushing device in order to be crushed further to form fractions. The fractions which have been crushed further are supplied to a screening device in order to be filtered to form at least a first and second part-stream. At least the first part-stream of fractions which have been crushed further and separated out by filtration is again passed along an eddy current separator which is driven at a rotary speed of less than 1000 rpm.

摘要： The present request privilege mentions an installation for mineralization garbage and, more particularly, to the technique for the attainment of you leave nutrients, without that the process after has the necessity of some type of treatment so that the end item, which is a saline mixture, either incorporated to the ground under the rich fertilizer form in you leave minerals. The process if unfolds in two phases: the phase of recycling and the phase of mineralization properly said. It presents as another very important characteristic, the fact of that effluent, gaseous, liquid all its and solid ones, are innocuous and do not generate impacts in the health and the environment.

摘要： A method and apparatus for treating mixed waste by pyrolysis. Organic mass is carbonized by heating to carbon in a pyrolysis reactor (3) in an oxygen-free environment. Pyrolysis gases are distilled for oil and the gases are used for energy production. Solid matter resulting from pyrolysis is sieved for separating inorganic coarse particles from a carbon fraction. The carbon fraction is milled in two operations, first with a roller mill (8) and then with a jet mill (10), a removal of metal being performed between the operations. The pulverized carbon fraction is classified by means of ionizing particle separators (11, 12, 13). The multi-stage particle separation is followed by discharging clean air and recovering fine carbon.

摘要： A method for removing ammonia and ammonia compounds from fly ash and other combustion by-products is provided. The method may be performed with raw or processed fly ash, or it may be performed in conjunction with a wet beneficiation process. The method involves mixing the ammonia-contaminated fly ash with water and then filtering and/or drying the solution to remove the ammonia and water. The method produces fly ash having an ammonia content of less than about 60-80 ppm, which allows the fly ash to be utilized in a number of applications.
