The combined drainage system sends all the urban domestic sewage, industrial wastewater and rainwater to a sewage plant for treatment and then discharges. A rainwater inlet is required to be designed for collecting rainwater in the combined drainage system and is communicated with the inspection well and the atmosphere. Due to closed oxygen deficiency in the inspection well, anaerobic microorganisms in the sewage perform anaerobic respiration to generate a large amount of gases with strong odor, such as hydrogen sulfide, ammonia, mercaptan and the like, and the gases escape into the atmosphere through the rainwater inlet. At night and in rainy days, the heat preservation effect in the inspection well is good, the temperature is high, the air pressure is high, the ground temperature is low, the air pressure is low, and the escape of odor in the inspection well is accelerated by the air pressure difference. Even in cold winter, the inlet for stom water can escape the hot gas that has the peculiar smell, pollutes city air, influences urban environment.
