Patent number: 12060291Abstract: Disclosed is a method for the treatment and resource utilization of acidic organic wastewater, comprising: (1) performing activated sludge treatment on acidic organic wastewater; and (2) performing microalgae treatment on the acidic organic wastewater treated in step (1). By means of the combination of activated sludge treatment and microalgae treatment, the present invention can significantly reduce the COD of the acidic organic wastewater. In some embodiments, the use of acclimated activated sludge or activated sludge having a specific microbial flora structure can not only improve the treatment efficiency while shortening the treatment time, but also omit a pH value adjustment step without causing sludge accumulation.Type: GrantFiled: October 17, 2019Date of Patent: August 13, 2024Assignees: CHINA PETROLEUM & CHEMICAL CORPORATION, SINOPEC NANJING RESEARCH INSTITUTE OF CHEMICAL INDUSTRY CO., LTD.Inventors: Haitao Li, Songbai Mao, Dong Wang, Xi Chen

Patent number: 10434461Abstract: A carbon dioxide absorbent is disclosed. The absorbent comprises organic amine, amino acid, and water, wherein said organic amine comprises tertiary amine and primary amine and/or secondary amine; and wherein amino acid is excess based on a stoichiometrical ratio of organic amine to amino acid in a reaction. A method for absorbing and desorbing carbon dioxide is further disclosed. In the absorbent system provided by the present disclosure, the conversion between primary (secondary) amine and (secondary) tertiary amine can be realized under the catalytic effect of amino acid with the changing of temperature, and carbon dioxide can be absorbed and desorbed effectively under a relatively low temperature.Type: GrantFiled: October 13, 2015Date of Patent: October 8, 2019Assignees: CHINA PETROLEUM & CHEMICAL CORPORATION, RESEARCH INSTITUTE OF NANJING CHEMICAL INDUSTRY GROUPInventors: Songbai Mao, Zhongbin Huang

Patent number: 9833740Abstract: A process of removing SO2 from a flue gas with a trickling filter using modified ceramsite packing is described. The biological flue gas desulfurization process includes: feeding the flue gas containing sulfur dioxide through the column bottom into the biomembrane trickling filter at certain temperature, contacting with the modified ceramsite biomembrane packing and purifying, which purified flue gas is discharged via the column top; and spraying the nutrient fluid rich in high concentration of the desulfurization strain through the top to the modified ceramsite biomembrane packing, thereby the sulfur-bearing pollution source in the flue gas is degraded, so as to discharge a purified flue gas satisfying the environmental requirements.Type: GrantFiled: June 18, 2014Date of Patent: December 5, 2017Assignees: CHINA PETROLEUM & CHEMICAL CORPORATION, RESEARCH INSTITUTE OF NANJING CHEMICAL INDUSTRIAL GROUPInventors: Aixiang Hao, Songbai Mao, Jing Kong
