Technical Field

[0001] The utility model relates to the technical field of photovoltaic wastewater treatment, in particular to a photovoltaic slicing wastewater deep treatment device. Background Art

[0002] In order to reduce the water consumption of photovoltaic production units, photovoltaic production companies generally treat photovoltaic slicing wastewater and then reuse it in the silicon wafer degumming unit. In order to reduce the risk of recycled water contamination to silicon wafers, the wastewater deep treatment unit will use sterilization equipment; in addition, the water temperature of the photovoltaic silicon wafer degumming unit is generally around 55°C, so the photovoltaic slicing wastewater will be heated before being reused in the silicon wafer degumming unit. The energy consumption required in this heating process is relatively high, and the photovoltaic degumming wastewater (temperature of about 55°C) is currently discharged directly, resulting in energy waste.
