After the release of "Tokujo", the demand for domestic soil remediation and treatment technologies increased, and many enterprises that have been deeply ploughed to remedy soil pollution also ushered in a huge space for development. Shandong Jinan Jiexing Environmental Protection Technology Co., Ltd. recently demonstrated its latest achievements in soil remediation in Beijing - the use of humic acid to recover chromium-contaminated soil. It is understood that humic acid is a kind of organic weak acid mixture formed by the decomposition and transformation of microorganisms and the residue of animals and plants as well as a series of geophysical processes. The biological liquid humic acid is used as a green remediation agent in the treatment of chromium-contaminated soil. After a series of reduction and curing reactions, the toxic hexavalent chromium in the soil will be reduced to non-toxic trivalent chromium, thus realizing the green remediation of heavy metal-contaminated soil. . According to Tian Yuyu, a professor at the China University of Petroleum, the "Cr"-contaminated soil remediation technologies currently used mainly include biological remediation, physical remediation, physical and chemical remediation, and chemical remediation, but all have drawbacks. "This release of the "green liquid humic acid bioremediation agent" uses non-polluting, non-toxic natural humic acid and natural plant extracts (biomass) as raw materials to maintain the natural state and biology of various structural components. The activity and its rich functional groups can not only reduce hexavalent chromium to trivalent chromium, detoxify the soil, but also improve the soil structure and restore the original planting function of the soil.No secondary pollution will occur during the entire restoration process. Various types of 'complications' that damage the soil structure," said Sun Mingguang, chairman of Shandong Innovation. Wang Xingrun, a researcher at the Chinese Research Academy of Environmental Sciences, also stated that the “bio-liquid humic acid green remediation agent†has a low repair cost, can effectively avoid the complications caused by previous soil remediation methods, and can also restore soil planting functions. He suggested that green soil remediation still requires a long-term regulatory process. Take "chromium" contaminated soil as an example, we must keep track and check whether the chromium in the remediation soil will once again change from non-toxic trivalent chromium to hexavalent chromium. , to ensure that there is no mistake and then promote a large area. The responsible person of Jinan Jiexing Environmental Protection Technology Co., Ltd. stated that under the full supervision of the authoritative organization, Jinan Jiexing Environmental Protection has applied this technology to the site remediation test of heavy metal chromium-contaminated soil. The SGS Shanghai Testing Center has detected that the original soil sample of the contaminated soil before remediation exceeds the national standard by more than 200 times. After the restoration, the soil has reached a series of restoration requirements such as the National Environmental Code for the Prevention of Chromium Slag Pollution and Environmental Protection. The plant growth in the soil is good, and the test reports on the roots, stems and leaves also meet the national standards for food safety.
