- Abstract:
- The scheme combining water purification and rainwater storage was selected for design of Lianggao constructed wetland in Handan. The process of detention pond, surface flow wetland and horizontal subsurface flow wetland was applied to treat the effluent from Hanlingou River, and the maximum treatment scale was 2 000 m3/d. Under the three operating conditions of conventional treatment, emergency treatment and internal circulation treatment, the main pollutant indexes of effluent were better than the class V limits specified in Environmental Quality Standards for Surface Water (GB 3838-2002), which could be used for greening irrigation and ecological water replenishment. On this basis, the detention pond and surface flow wetland could be used as stormwater regulation and storage areas to regulate and store the stormwater from Hanlingou River during flood season. The maximum storage volume was 6 000 m3, which alleviated the flood discharge pressure of the river.
