A reducing water purification material having a reducing iron-based precipitate selected from green rust, iron ferrite, reducing iron hydroxide, and a mixture thereof. A wastewater treatment process having steps of adding a reducing iron compound to wastewater, leading the wastewater to which the reducing iron compound is added to a reaction tank and forming a precipitate, separating the formed precipitate by a solid-liquid separation to obtain a sludge, and alkalinizing all or a portion of the separated sludge to form an alkaline sludge followed by returning to the reaction tank, wherein in the precipitation step, the wastewater to which the reducing iron compound is added and the alkaline sludge are mixed and are allowed to react in a non-oxidizing atmosphere under alkaline condition to form a reducing iron compound precipitate as the precipitate, thereby incorporating contaminants in the precipitate to remove the contaminants from the wastewater.

An intake device for an internal combustion engine includes a throttle body () that forms an intake passage (). A throttle valve () is arranged within the intake passage. A pipe member () is connected to the throttle body, wherein the pipe member forms a communication passage () communicating with the intake passage. An engagement device () is provided between the throttle body and the pipe member. The engagement device includes at least one engagement protrusion () and at least one engagement recess (M). When the engagement protrusion and the engagement recess are engaged with each other, detachment of the throttle body and the pipe member from each other is restricted. The assembly process is simplified by a lack of separate components such as clamps and bolts, relying instead upon a typical snap-fit connection.
