Problems solved by technology

First of all, because the waste importing countries basically lack the technical means and economic capacity to deal with and dispose of hazardous waste, the import of hazardous waste will inevitably lead to damage to the local ecological environment and human health.
Secondly, the spread of hazardous waste to underdeveloped areas is actually to evade the disposal responsibility stipulated by the country, so that hazardous waste is not properly treated and disposed of and spread into the environment. The long-term accumulation will inevitably cause harm to the global environment.
[0004] Now there are many treatment methods for these hazardous wastes, but according to the different types of hazardous wastes, the treatment methods are also different. Now the treatment of electroplating sludge has always been a thorny problem. Now my country's treatment processes and methods for this type of hazardous waste are still relatively rare

Abstract

The invention discloses an electroplating-sludge cement curing process. The electroplating-sludge cement curing process includes: firstly, delivering electroplating sludge to a dry grinding box through a conveyor belt device for dry grinding; transferring the electroplating sludge subjected to dry grinding to a storage groove through a lifting mechanism; discharging the electroplating sludge in the storage groove to a blending mixer through a metering device; adding cement, water and additives to the blending mixer through power supply equipment for blending mixing through the blending mixer;transferring a mixed mixture to a forming machine through a transferring device for forming; transporting formed cement blocks to a curing chamber through a belt conveyor for static solidification storage; finally, carrying away the cement blocks through a transport vehicle. The process is smooth, capable of achieving curing processing of the electroplating-sludge cement, environment friendly andreliable and current use requirements are met.

Description

technical field [0001] The invention relates to a solidification process, in particular to an electroplating sludge cement solidification process. Background technique [0002] With the development of industry, the hazardous waste discharged from industrial production process is increasing day by day. It is estimated that 330 million tons of hazardous waste are generated worldwide each year. Due to the serious pollution and potential serious impact of hazardous waste, hazardous waste has been called "political waste" in industrially developed countries. The public is very sensitive to the problem of hazardous waste and opposes the establishment of hazardous waste disposal sites in the areas where they live. Disposal of hazardous waste is expensive, and some companies try to transfer hazardous waste to industrially underdeveloped countries and regions. [0003] The magnitude of this transboundary movement of hazardous waste is difficult to quantify, but is clearly growing. ...
