Problems solved by technology

[0002] With the development of my country's industrial economic construction, the continuous expansion of industrial production scale has led to a sharp increase in solid waste. The conventional method is to use deep underground landfill, which not only takes up a lot of land, but also seriously pollutes the environment and groundwater resources. The living environment brings great harm

Embodiment 1

[0013] When producing the counterweight, the roasted metal powder is mixed with cement and water and molded to form a shape. The specific mixing ratio is as long as the cement can solidify. This is Example 1 of producing the counterweight;

Embodiment 2

[0014] Mix the following parts of materials, 60-80 parts of metal powder, 10-20 parts of epoxy resin, 10-20 parts of thinner, 0.3-0.4 parts of curing agent, 0.3-0.5 parts of toughening agent , the best ratio is 70 parts of metal powder, 15 parts of epoxy resin, 15 parts of diluent, 0.35 parts of curing agent, and 0.4 parts of toughening agent, stir quickly, and mold and shape within 5 minutes to 15 minutes. The best time is 10 minutes; Described diluent is xylene, and described curing agent is ethylenediamine, and described toughening agent is dibutyl ester, and this is the embodiment 2 of production counterweight;

[0015] Mix 40-60 parts of waste plastic powder with 40-60 parts of metal powder, and then die-cast plastic counterweights on a die-casting machine. This is Example 3 for producing counterweights.

[0016] The waste metal sludge is any one or any combination of metal pickling sludge, pharmaceutical and chemical iron sludge, pesticide and chemical iron sludge, pyrom...

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 [0001] The invention relates to a technology for treating industrial solid waste metal sludge, in particular to a recycling method for waste metal sludge. Background technique [0002] With the development of my country's industrial economic construction, the continuous expansion of industrial production scale has led to a sharp increase in solid waste. The conventional method is to use deep underground landfill, which not only takes up a lot of land, but also seriously pollutes the environment and groundwater resources. The living environment brings great harm. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a method for recycling waste metal sludge, which can make metal solid waste sludge a renewable resource for recycling, which is environmentally friendly and pollution-free, and avoids the waste of water resources caused by deep burial of industrial solid waste. and human environmental pollution. ...
