    摘要： In an activated sludge treatment of organic waste water, excess sludge from the activated sludge aeration vessel is processed with hypochlorous acid in place of ozone without set up of aeration vessels and blowers to improve volume reduction cost of sludge without deterioration of water quality. The hypochlorous acid process is carried out by using an acidulous sodium hypochlorite aqueous solution which is prepared by mixing sodium hypochlorite aqueous solution with a dilute hydrochloric acid and diluting the resulting mixture with water within 1,000 ppm to 50,000 ppm of available chlorine concentration at a pH zone of more than 4 to less than 7.

    摘要： This invention provides a covered member which possesses a high bond strength of a base material and a covering film, and has a smooth surface. The covered member comprises a base material and a covering film and the surface of the base material to be covered with the covering film is characterized by an uneven surface having projections with an average height in the range from 10 to 100 nm and an average width of not more than 300 nm. The uneven surface can be formed by ion impacting. A surface of a covering film formed on that is smooth since the unevenness of the surface is extremely fine.

    摘要： A coating film removal method for a coated member having a coating film formed over the surface of a substrate is disclosed, which can easily achieve a coating film removal, even for a carbon-based coating film containing carbon as a main component, besides a carbon-based coating film containing a metal element etc. A coated member regeneration method is also disclosed, which removes a coating film from a coated member, and then forms a new coating film over the member, to regenerate the coated member. The coating film removal method is adapted to remove a carbon-based coating film from a coated member (10) including a substrate, and the carbon-based coating film coated on at least a portion of a surface of the substrate while containing carbon as a main component. The coating film removal method includes bringing a molten salt having an oxidizing function for carbon into contact with the carbon-based coating film, to remove at least a portion of the carbon-based coating film coated over the surface of the substrate. A coated member regeneration method includes removing the carbon-based coating film from the coated member, using such coating film removal method, and subsequently forming a coating film on at least a portion of a surface of the film-removed member (11).

    摘要： A nitride or carbonitride layer is formed on the surface of a metal material as follows: A treating agent composed of a refractory powder of alumina or the like and a powder of a metal for forming a nitride or a carbide or an alloy thereof is disposed in a fluidized bed furnace; the treating agent is fluidized to form a fluidized bed by introducing an inert gas; the fluidized bed furnace is heated to a temperature of not higher than 700.degree. C.; an activator of a halogenated ammonium salt is intermittently supplied into the fluidized bed at a rate of 0.001 to 5 wt %/hour based on the total amount of the treating agent; and the metal material to be treated is disposed in the fluidized bed during or after any of the above steps. For example, a nitride layer composed of only a metal for forming a nitride which contains almost no Fe--N is formed on the surface of iron steel even at a temperature as low as not higher than 700.degree. C. The layer is very hard and efficient in wear resistance, and the toughness of the base metal is hardly lowered.
