Due to infringement disputes caused by soil pollution, Shanghai Lujiazui Group took five parties including Suzhou Iron and Steel Group to court, seeking compensation of 10.04 billion yuan from Suzhou Iron and Steel Group. The core issues behind this incident are as follows:

The land survey conclusions are inconsistent and suspected of fraud and violation of information disclosure obligations. When Suzhou Iron and Steel Group transferred its equity, it concealed the results of a public report, which showed that benzopyrene and naphthalene in the soil seriously exceeded standards. Later official investigation results overturned the Suzhou Iron and Steel Group's statement that "the land is basically not contaminated."

The change of land use without approval violates the original intention and requirements of the Suzhou Municipal Government to support the transformation and upgrading of Suzhou Iron and Steel Group. Suzhou Iron and Steel Group treated Green Bank as a pure real estate development enterprise and transferred 95% of its equity to external parties, deviating from a series of agreements and documents signed with the Suzhou High-tech Zone Management Committee. The Suzhou High-tech Zone Management Committee requested the transaction be suspended, but in the end the parties reached an agreement and Lujiazui was able to continue developing the land.

The soil pollution control and restoration are not in place, affecting the health and safety of surrounding residents and students. During the development and construction period, Lujiazui Group failed to build groundwater barrier walls and take other protective measures in accordance with relevant requirements. It disturbed groundwater, moved soil and caused cross-contamination of some environments, and irregular construction operations caused secondary pollution. There is a risk of soil contamination in plots already occupied by residents and plots that have been developed and constructed.

So in practice, how to avoid or reduce the occurrence of such incidents, such as soil contamination in similar cases, and under the current situation, what are any good suggestions for remediation?

The skid-mounted and mobile soil washing equipment developed by Desen Environment are involved in many different types of soil remediation projects. For example, the 100 t/h Changsha Chromium Salt Plant Chromium Pollution Overall Treatment Project, Guangzhou Shipyard Heavy Metal Soil Pollution Remediation Project, Hangzhou Iron and Steel Contaminated Soil Remediation Project, Maanshan Iron and Steel Contaminated Soil Remediation Project, etc. The entire process flow is divided into seven modules, which have the functions of crushing and feeding, scrubbing, hydraulic screening, enhanced washing, cyclonic dehydration, concentration and filtration. It does not change the original purpose of the soil and can effectively reach the construction land. standards. in:

The first phase soil remediation project of Guangzhou Shipyard Heavy Metal Soil Pollution Remediation Project was selected as the 2021 Guangdong Province Environmental Protection Excellent Demonstration Project. The heavy metal content in the soil was reduced to safe utilization standards through Desen high-efficiency soil washing. The treated soil does not need to use barrier fill The buried area is blocked and filled, which greatly improves the land utilization efficiency. At the same time, the screened sand can be directly backfilled or used as construction auxiliary materials for resource utilization.

The skid-mounted modular soil washing and remediation equipment used in Maanshan Iron and Steel's contaminated soil remediation project is manufactured by Desen Environmental. It is a professional and efficient remediation equipment specially designed for ex-situ washing of contaminated soil. It can be installed quickly and easily transferred. field. The configured production capacity range is 20-25 tons/hour. It has the advantages of wide application range, strong system scalability, full-process PLC intelligent control, good module connection, and high operating efficiency.

People familiar with the Suzhou Iron & Steel Co., Ltd.'s "Ten Billion Poison Land" incident said that it is very difficult in terms of cost and repair methods. If it is completely repaired, the damage will be immeasurable and it will take a long time. At present, the problems reported by the environmental protection inspection team mainly include problems in the previous land regulation changes, educational land regulation changes, and the land transfer process in 2016. However, no solution has been reached yet. Let us continue to pay attention to the development of events!
