Sewage treatment system

The utility model provides a sewage treatment system which comprises an oil separation tank and a water basking tank, the oil separation tank is communicated with the water basking tank through a communicating pipe, one end, extending into the oil separation tank, of the communicating pipe is further communicated with an oil separation section, the oil separation section is located in the oil separation tank, and a preset included angle is formed between the oil separation section and the communicating pipe. Oil is prevented from entering the communicating pipe through the end opening of the oil separation section and flowing into the water basking pool, the content of the oil in the water basking pool is reduced, and the evaporation speed of water in the water basking pool is increased. 本实用新型提供一种污水处理系统，包括：隔油池和晒水池，所述隔油池和所述晒水池通过连通管连通，其中，所述连通管中伸入至所述隔油池内的一端还与隔油段连通，所述隔油段位于所述隔油池内，且所述隔油段与所述连通管成预设夹角。避免了油液通过隔油段的端口进入连通管流入晒水池中，减少晒水池中有油液的含量，提高了晒水池中的水分的蒸发速度。
