The present invention discloses an ecological restoration pool for sewage bodies for ecological restoration of lake pollution, which belongs to the technical field of ecological sewage treatment, and includes a self-adjusting assembly, a rotating drive component, an aeration adjustment component, an aeration plate, and a crossbeam fixed on the pool body, wherein the aeration plate is used to aerate the bottom of the pool body; the self-adjusting assembly is connected to the rotating drive component for adjusting the output speed, the self-adjusting assembly is connected to the aeration adjustment component for adjusting the air intake, and the aeration adjustment component is connected to the rotating drive component. By arranging the self-adjusting assembly, the rotating drive component, and the aeration adjustment component, the present invention can automatically adjust the stirring speed and the aeration speed according to the temperature when the ambient temperature changes, so as to ensure the activity of microorganisms and the sewage treatment speed, and effectively solve the problem that the current ecological restoration pool for sewage treatment cannot adapt to the temperature difference change, resulting in the inhibition of microbial activity and low sewage treatment efficiency.

The present invention discloses an automobile exhaust reforming device and a reforming system, which are used to introduce a mixed gas of automobile exhaust and methane. The automobile exhaust reforming device comprises: a shell having a cavity, an air inlet and an air outlet, a first baffle, a catalytic element and a cooling assembly. The first baffle is built into the shell and divides the cavity into a catalytic cavity and a cooling cavity which are independent of each other. The catalytic cavity is connected to the air inlet, and the cooling cavity is connected to the air outlet. The catalytic element is connected to the inner wall of the catalytic cavity to promote the occurrence of a catalytic reaction. The cooling assembly comprises at least one heat exchange tube and a heat exchange medium built into the cooling cavity, and one end of the heat exchange tube is connected to the catalytic cavity and the other end is connected to the air outlet. The heat exchange medium is filled between the inner wall of the cooling cavity and the outer wall of the heat exchange tube, and is used to cool down the material in the heat exchange tube. The present invention can solve the problem that the reformer has low reforming efficiency for automobile exhaust due to the lack of a cooling device, and can improve the utilization of waste heat of engine exhaust and the combustion effect.
