Long-term stability test device and test method of heavy metal ion solidification products

Abstract

The invention discloses a heavy metal ion curing product long-term stability test device and a test method. The device comprises a liquid chamber (1), a gas chamber (2), a funnel (3), a container (4) and a permeable membrane (8), the liquid chamber (1) is disposed above a curing product, the gas chamber (2) is disposed around the curing product, the curing product is communicated with the gas chamber (2) through the permeable membrane (8), the liquid chamber (1) is internally provided with a extracted solution, a seal cover (5) is arranged above the liquid chamber (1), and the gas chamber (2) is internally provided with CO2 gas. The method comprises the steps of: applying the permeable membrane around the curing product, and 1d later placing the curing product above the hopper; injecting the extracted solution into the liquid chamber; filling the gas chamber with CO2 gas; and adjusting the pressure applied above the seal cover, thus realizing simulation of the carbonation-acid-seepage environment. The device provided by the invention has the advantages of low cost and simple structure, and realizes simulation of the carbonation-acid-seepage environment.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a long-term stability test device and test method for heavy metal ion solidification products. Background technique [0002] According to relevant statistics, my country produces 784 million tons of industrial solid waste every year, including 10.15 million tons of hazardous waste. And it is increasing year by year at a rate of about 8-10%. Most of these wastes contain heavy metal elements that are a serious threat to humans and the living environment. Heavy metal pollution has seriously hindered the development of the national economy and society, and threatened human health. ignore. How to deal with heavy metal pollution scientifically and rationally, and realize harmlessness and resource utilization, has become a hot spot that the whole society pays attention to. [0003] Solidification technology is suitable for the treatment of heavy metals in up to 56 ki...
