[0002] Bathing wastewater refers to wastewater generated during personal cleaning activities such as bathing, washing hair, and washing hands. These wastewaters usually contain suspended matter, grease, soap scum, bacteria and other pollutants. The treatment of bathing wastewater is very important for environmental protection and water resource utilization. For public bathrooms, hotels, dormitories and other places, reasonable design and management of bathing wastewater systems can reduce water resource waste and environmental pollution. Therefore, there is an urgent need for a heat pump waste heat recovery device for bathing wastewater in the market.

[0003] However, the prior art still has the following problems:

Since the suspended matter in the bathing wastewater is mostly hair, and the filtration system is installed in the wastewater tank or wastewater pipe, it is inconvenient to disassemble and clean it. If the filtration system is not cleaned for a long time, it is easy to cause blockage of the water tank or water pipe.

[0005] Secondly, when heating clean water, the existing bathing wastewater heat pump recovery device usually exchanges heat between the wastewater and the clean water, and then transfers the clean water to the heating device. Part of the heat of the clean water will be lost during the transfer. At the same time, the heating device generally uses coal burning for heating. The whole process is too slow and not conducive to environmental protection.

[0006] In view of the above problems, the inventors proposed a heat pump waste heat recovery device for bathing wastewater to solve the above problems. Utility Model Content
