Abstract
The invention relates to a method for recovering and utilizing waste metal sludge. It is characterized in that the waste metal sludge can be recycled as renewable resources, which causes no pollution and avoids the harm for water resource and human environment brought from industrial solid waste deep bury. The method comprises adding hydrogen peroxide and potassium permanganate into waste metal sludge for oxidation, which combines with autoxidation to form metal powder that is suitable for extraction.
Description
Technical field
The present invention relates to industrial solid castoff metal sludge treatment technology, be specially the discarded metal sludge recoverying and utilizing method.
Background technology
Development along with China's industrial economy construction, the continuous expansion of commercial production scale, caused the sharp increase of solid waste, conventional way adopts the underground landfill of deep layer exactly, this not only takies a large amount of soils, and serious environment pollution and groundwater resource, bring very big harm to existent environment of people.
Summary of the invention
At the problems referred to above, the present invention aims to provide the discarded metal sludge recoverying and utilizing method, it can make the metal solid waste sludge become the renewable resource recycle, and is environment friendly and pollution-free, the harm of having avoided the water resources brought after the buried processing of industrial solid castoff and human environment to pollute.
Technical scheme of the present invention, the discarded metal sludge recoverying and utilizing method:
It is characterized in that: hydrogen peroxide and potassium permanganate carry out strong oxidation and the air natural oxidation forms the metal powder material that is fit to refinement with adding in the discarded metal sludge.
It is further characterized in that: metal powder material ironmaking that iron level is high or production counterweight or production raw material cement, the metal powder material that iron level is low is produced raw material cement or is carried out roasting, maturing temperature is at 1200 ℃～1300 ℃, and the powder after the roasting can be used for ironmaking or produce counterweight;
Produce counterweight, with the metal powder material after the roasting and cement, water mixing mold pressing typing, concrete blending ratio is as long as cement can solidify;
Produce counterweight, material mixing with following umber, 60 parts～80 parts of metal powder materials, 10 parts～20 parts of Resins, epoxy, 10 parts～20 parts of thinners, 0.3 part～0.4 part in solidifying agent, 0.3 part～0.5 part of toughner, stir fast, at 5 minutes～15 minutes internal mold compression set types, described thinner is a dimethylbenzene, and described solidifying agent is the second diamino, and described toughner is dibutylester;
Produce counterweight: 40 parts～60 parts of the powders of plastic waste are mixed for 40 parts～60 parts with metal powder material, go up pressure die-casting machine then and be cast into the plastics counterweight;
Described discarded metal sludge is any or any several mixture in the mud that forms of metal pickling mud, pharmaceutical chemical industry iron mud, pesticide chemical iron mud, pyrometallurgy mud, metallurgical spent acid and dyeing waste water neutralizing treatment.
The present invention can make the metal solid waste sludge realize pollution-free recycle and resource recovery, make the waste of discharging become the environmental type iron ore of China's output maximum, solved the water resources and the human environment pollution hazard that bring after the buried processing of industrial solid castoff of the annual up to ten million tons of present China.
