This utility model discloses a high-efficiency industrial wastewater treatment device, including a wastewater processor and a drain pipe installed on one side of the wastewater processor. One end of the drain pipe is connected to an anti-clogging component to prevent blockage during wastewater treatment. The anti-clogging component includes a diverter, a main pipe, a secondary pipe, a conical block, a sealing ring, and a spring. The main pipe and the secondary pipe are installed between two diverters. In this utility model, normal wastewater enters the main pipe through the diverter, and the main pipe then discharges the wastewater into the wastewater processor through the diverter. When the main pipe is blocked, the increased water pressure in the diverter will push the sealing ring to move. The sealing ring will move along the slide groove via a slider, so that the sealing ring cannot cooperate with the conical block to seal the secondary pipe. The wastewater will flow into the diverter through the secondary pipe, and the diverter will then discharge the wastewater into the wastewater processor through the drain pipe. In this way, if a blockage occurs during wastewater treatment, the blockage can be cleared after the wastewater treatment is completed.

This utility model belongs to the field of cadmium telluride BIPV technology, specifically relating to a cadmium telluride insulated photovoltaic glass for back-connected junction boxes. It includes an outer encapsulation glass layer, with a cadmium telluride power generation chip adhered to one side of the outer encapsulation glass layer, and an inner encapsulation glass layer adhered to the side of the cadmium telluride power generation chip away from the outer encapsulation glass layer.
