Problems solved by technology

[0004] In the above process, all copper-containing solid wastes are treated uniformly, and hazardous wastes in copper-containing substances are not treated differently, causing environmental pollution. At the same time, the treatment process does not take into account the various copper-containing wastes. Specificity, causing problems of incomplete treatment and environmental pollution

Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0054] refer to figure 1 , is a copper-containing hazardous waste treatment process disclosed in the present invention, including Class I hazardous waste incineration, Class II hazardous waste pretreatment, brick making, copper brick smelting and flue gas treatment.

[0055] Among them, Class I hazardous waste refers to other hazardous wastes except HW49, such as HW12 dye, paint waste, HW17 surface treatment, HW22 copper-containing waste, HW45 organic halide-containing waste, HW46 nickel-containing waste, HW48 non-ferrous metal smelting waste , HW50 waste catalyst, etc. Class II hazardous waste refers to HW49 hazardous waste, and the common one is waste circuit boards.

[0056] refer to figure 2 , Class I hazardous waste incineration includes two steps of batching and incineration, specifically: use purchased copper-containing general solid waste, at leas...

Abstract

The invention relates to a copper-containing hazardous waste treatment process, relates to the technical field of copper-containing waste treatment, and aims to solve the problems of incomplete treatment and environmental pollution caused by the fact that the specificity of various copper-containing wastes is not considered in the existing copper-containing waste treatment process. The process comprises the steps of class I hazardous waste incineration, class II hazardous waste pretreatment, brick making and copper brick smelting; class I hazardous waste incineration includes proportioning andincinerating to obtain combusted clinker; class II hazardous waste pretreatment includes the steps of pretreating HW49 hazardous wastes to remove organic matters, and collecting copper-containing powder; brick making comprises the steps of mixing the clinker collected after incineration of class I hazardous waste and copper-containing powder collected in class II hazardous waste pretreatment, andcarrying out briquetting treatment to prepare a copper-containing brick; and copper brick smelting comprises the step of feeding the copper-containing brick into a side blowing furnace for smelting to produce matte. The copper-containing hazardous waste treatment process can carry out differential treatment according to the characteristics of copper-containing hazardous wastes, and has the advantages of high copper conversion rate and small environmental pollution.

Description

technical field [0001] The invention relates to the technical field of copper-containing waste treatment, in particular to a copper-containing hazardous waste treatment process. Background technique [0002] In daily life and production, copper-containing solid waste comes from a wide range of sources and complex components, mainly including copper sludge and environmental protection sludge produced in the purification process containing heavy metals, electroplating sludge produced in the electroplating industry, sponge copper produced in various manufacturing industries and Waste circuit boards, etc. Some copper-containing waste has been included in the national hazardous waste list HW49, such as waste circuit boards (including components, chips, plug-ins, stickers, etc. attached to waste circuit boards). [0003] In order to solve the problem of reutilization of copper-containing solid waste resources, the Chinese invention with the publication number CN106399692A disclos...
