The invention discloses an excess sludge reduction bioreactor with variable aeration and a worm attachment oblique plate, which relates to a bioreactor for excess sludge reduction. The bioreactor solves the problems that that the conventional excess sludge reduction device has low oxygen utilization rate, poor aeration adjustment, easy worm drop, low growth density of worm colony, difficult discharge of inert substances and the like. An automatic gas flow adjustor which is well arranged can automatically adjust the air flow entering a plurality of variable micropore aeration pipes according to the dissolved oxygen concentration of sludge mixed solution in a container, thereby realizing variable aeration for the sludge mixed solution in the container; the dissolved oxygen concentration of the sludge mixed solution can be kept at the maximum dissolved oxygen concentration of the worm sludge reduction through the variable aeration; and a plurality of variable aperture vent holes are uniformly distributed on the variable micropore aeration pipes, and the variable range of the diameters of the vent holes is 0.2 to 0.8 millimeter. The excess sludge reduction bioreactor integrates the worm attachment oblique plate and the variable aeration so as to greatly improve the sludge reduction effect, and the sludge reduction reaches over 90 percent.

The objective of the present invention is to provide a composite which is obtained by firmly bonding a thermoplastic resin and a metal without deteriorating the characteristics of the thermoplastic resin. In order to achieve the objective, the present invention provides a composite obtained by contact bonding a thermoplastic resin composition (A) and a metal (B), wherein the thermoplastic resin composition (A) contains a thermoplastic resin and an inorganic filler that increases the crystallization temperature of the thermoplastic resin by 3 DEG C or more and the metal (B) is a surface-treated metal. It is preferable that the thermoplastic resin is a polyamide resin. It is also preferable that the inorganic filler is composed of at least one substance that is selected from the group consisting of talc, graphite, magnesium oxide, kaolin and calcium carbonate.
