After the chemical plant is relocated, the issue of site pollution remediation deserves further investigation!
The pollution left to the soil after the relocation of the chemical plant is extremely serious. According to the site remediation case of a domestic chemical plant, in addition to organic matter (ethylbenzene, xylene, C9-C30 aromatic solvents), the characteristic pollutants of the paint factory site
The pollution left to the soil after the relocation of the chemical plant is extremely serious. According to the site remediation case of a domestic chemical plant, in addition to organic matter (ethylbenzene, xylene, C9-C30 aromatic solvents), the characteristic pollutants of the paint factory site also include heavy metals. The pollution characteristics are "linear", and the vertical migration distribution degree becomes worse and the content decreases synchronously. The surface points and the corresponding shallow points show a significant positive correlation. According to the coating process characteristics and the actual measurement results of the case, the surface Cr content is the highest, followed by Cu, Zn, and Cd content, and the average pollution depth is 40cm. The comprehensive pollution degree of the surface soil (0-20cm) of each block is ranked as follows: road block > production block > raw material storage block.
The pollution of the soil by chemical plants is very serious. If the plant is abandoned or relocated and the soil on the site cannot be repaired, it will cause a huge waste of resources. In the process of pollution remediation of chemical plant sites, what soil remediation technologies and equipment are used, how to reduce the concentration of soil pollutants to an acceptable level or convert them into harmless substances, and how to prevent and repair are topics worthy of in-depth research.
Desen washing equipment has been successfully applied to representative comprehensive restoration projects in China, such as the Shanghai Putuo Chemical Site Remediation Project, Changsha Chromium Salt Plant Remediation Project, Hangzhou Steel washing and restoration project, Guangzhou Shipyard washing and restoration project, Mahe Steel washing project, Ningbo washing project, and Dahua Shovel Bay restoration project, through sales or leasing. The total volume of soil washing treatment in the participating projects exceeds 1 million tons.
Desen Environment keeps a close eye on market demand and always insists on the close integration of design and project application. Through the accumulation of experience from hundreds of project cases, the system equipment is continuously optimized and upgraded in terms of "applicability of various materials for the project, convenience of installation and commissioning, and intelligent equipment control". At present, the modular washing equipment has been updated to the tenth generation. Behind each iteration and upgrade, the "craftsmanship" attitude of the Desen team is condensed.
