- Abstract:
- Huangxiao River and Jichang River are important rivers in Hankou area. However, due to inadequate overflow pollution control in the combined sewer system area, there is significant pollution during rainy seasons, further deteriorating water quality post-rain. To enhance the water environment quality of Huangxiao River and Jichang River basins, through InfoWorks model calculation and existing facilities analysis, this study examined the impact of small, medium, large, and heavy rainfall events based on two typical annual rainfalls to understand the relationship between overflow control and annual overflow occurrences from the water quality and quantity directions. The results indicated that with the increase of rainfall, the amount of overflow increases gradually and the average concentration of overflow pollutant increases first and then decreases. The escalation in overflow is more pronounced, yet effective control manages both the total overflow volume and pollution concentration better at approximately 10 annual overflow occurrences.
