Patent number: 11292038Abstract: A combined remediation method of petroleum-contaminated soil includes: impurity removal pretreatment, photocatalytic pre-oxidation, stepwise thermal desorption of petroleum from soil, and high-temperature oxidation; with iron-titanium composite metal oxide (ITCMO) as a catalyst, conducting oxidation pretreatment under light conditions so that some cross-linked structures in macromolecular petroleum contaminants are broken and degraded; and conducting stepwise pyrolysis to achieve a removal rate of more than 98.00%. The new method adopts a combined remediation technology of photocatalytic pre-oxidation-stepwise pyrolysis, which realizes a relatively-high removal rate of petroleum hydrocarbons and the efficient and harmless remediation of high-concentration petroleum-contaminated soil, and remedied soil can be reused.Type: GrantFiled: October 19, 2020Date of Patent: April 5, 2022Assignee: CHINA UNIVERSITY OF PETROLEUMInventors: Dong Liu, Shuhai Guo, Wei Zhu, Fushan Wen, Nan Shi, Yu Qiu, Xiaoning Feng, Bo Wu, Gang Li, Changlong Yin, Xiujie Yang, Dehui Kong, Hongbo Dai, Mengfei Li, Sa Wang

Patent number: 9162264Abstract: A system and a method for remediation of organic contaminated soil are provided, which comprises M*N electrodes to form an electrode matrix of symmetrical electric field structure. The field intensity is uniform in those points that are equidistant from each electrode in remediation area. The electrodes arrayed in mesh style in remediation area are carried out electrokinetic remediation. To exchange between positive polarity and negative polarity of the electrodes periodically is to make each electrode be a state of anode intermittently which has preferable remediation efficiency, by operation mode of reversing row/column electrode groups in manner of electrical scanning.Type: GrantFiled: January 4, 2009Date of Patent: October 20, 2015Assignee: SHENYANG INSTITUTE OF APPLIED ECOLOGY, CHINESE ACADEMY OF SCIENCESInventors: Shuhai Guo, Tingting Li, Wang Yanhua, Liu Kunpeng, Li Fengmei, Li Gang
