摘要： PROBLEM TO BE SOLVED: To provide a method of treating wastewater containing a nitrogen compound, whereby stabilized high-efficiency denitrification is made possible, the treatment cost is reduced the operation management is easy, and the equipment can be made to be compact and the space for the equipment can be saved. SOLUTION: The treatment efficiency is improved by performing denitrification without obstructing the nitrate aspiration of microbes by deaeration prior to the denitrification. The cost of chemicals is reduced by replacing methanol generally used as an organic carbon source by blackstrap molasses. By providing an immersion type membrane separation apparatus 27 in an aerator 26 and in a group of bubbles formed in aeration, the plugging of the surface of the membrane of the apparatus is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a method for treating waste plastics, by which a desired oil or gas can easily be recovered from the waste plastics in remarkably improved heat profitability, and to provide a device therefor. SOLUTION: A preheater 7 for preliminarily heating air E1 for combustion with the residual heat of a combustion gas B1 produced by a combustion reaction on a burner 3 is disposed. Thereby, the residual heat of the combustion gas B1 is recovered without relating to the heating of the slurry A1 of waste plastics, and then recycled as heat energy for heating the slurry A1. Therefore, the residual heat of the combustion gas B1 can sufficiently be recovered to remarkably enhance the total heat efficiency without affecting the treating conditions of plastic cracking reactions.

摘要： PROBLEM TO BE SOLVED: To properly treat supercritical waste water containing an oily component by subjecting the supercritical waste water to microbial treatment using petroleum hydrocarbon metabolizing microorganisms. SOLUTION: Supercritical waste water is subjected to microbial treatment using petroleum hydrocarbon metabolizing microorganisms. In a treatment method of supercritical waste water, bacteria belonging to the genus Corynebacterium or yeats belonging to the genus Debaryomyces are pref. used. Since these microorganisms have far higher capacity for emulsifying an oily substance to decompose the same as compared with usual activated sludge, an oily component can be decomposed and metabolized extremely efficiently without adding a surfactant. Therefore, respective components in an oily substance contained in supercritical waste water can be decomposed and removed efficiently.
