Embodiment 2
[0045] Example 2 Environmentally friendly and rapid purification of soil heavy metal pollution
[0046] 1. Utilize the system device described in claim 1 to purify soil polluted by heavy metals in soil. Proceed as follows:
[0047] (1) First, the distribution of heavy metal ions in soil particles of different sizes will be analyzed to determine the content distribution of heavy metals in soil particles of different sizes.
[0048] Sieve soil particles of different particle sizes with a replaceable drum sieve 1, determine the screen hole size of the drum sieve 1 according to the above analysis results, and pass through the drum sieve 1 to filter the soil containing less or no heavy metal ions Particles 11 (that is, light or non-polluted soil) are sieved out (usually soil particles with larger particle sizes contain less heavy metal ions), and the soil particles 11 in the sieve bucket are directly backfilled to the soil borrowing site. The sieved aqueous solution 12 of heavy...

Abstract
The invention discloses a rapid environment-friendly heavy soil metal pollution treatment and purification system. The system comprises a screen-replaceable rotary screen, a hydrocyclone, a sprinkling stirring tank, a reaction tank, a sedimentation basin, a regulating reservoir reaction region, a regulating reservoir storage region and a plate-and-frame filter press. The screen-replaceable rotary screen, the hydrocyclone, the sprinkling stirring tank, the reaction tank, the sedimentation basin, the regulating reservoir reaction region and the regulating reservoir storage region are sequentially connected. The regulating reservoir storage region is connected with the sprinkling stirring tank. The reaction tank and the sedimentation basin are connected with the plate-and-frame filter press. A backflow channel is arranged between the hydrocyclone and the screen-replaceable rotary screen. The system has the beneficial effects of being high in efficiency, quick, environmentally friendly, capable of achieving engineering treatment easily and the like, the purification effect on soil with heavy metal pollution and work efficiency can be remarkably improved, no wastewater is drained from the whole system, the environment-friendly benefit is achieved, the important technique and equipment are provided for heavy soil metal pollution restoration work of China, and social and environmental benefits are remarkable.
Description
technical field [0001] The invention belongs to the technical field of purification and restoration of soil heavy metal pollution, and in particular relates to an environment-friendly system for rapid treatment of soil heavy metal pollution and purification. Background technique [0002] At present, my country's soil heavy metal pollution is becoming more and more serious. With the development of society, the lack of production management and the random discharge of waste have caused serious soil heavy metal pollution. Soil heavy metal pollution will destroy the surrounding ecological environment and has threatened human health. Therefore, the purification and restoration of heavy metal-contaminated soil has become a major scientific issue and a livelihood issue of public concern, and has become an urgent task for all walks of life. [0003] There are numerous reports on remediation methods for soil heavy metal pollution. Soil heavy metal pollution remediation methods main...
