With the advent of the Meiyu season, Expo site

drainage system

Can he withstand the storm test this summer? For this reason, reporters yesterday interviewed the Shanghai urban design and Design Institute for the drainage system of the Expo site.

Experts in the hospital said, "even if it is heavy rain, tourists will not be easily wetted by the rain on the road of the Expo site."

The drainage capacity of the park exceeds that of the Bund.

According to reports, the flood season in Shanghai has lasted for 4 months, especially in recent years, which has been attacked by short time rainstorms. The maximum hour rainfall is as high as 95 millimeters. It has far exceeded the average drainage capacity of Shanghai with an average of 36 millimeters per hour.

However, the responsible person of the urban construction and Design Institute revealed that the upgrading of the drainage and pollution control system in the city has also begun.

Through investigation, it is determined that the design of urban rainwater pipe network reaches 50 millimeters per hour and the limit reaches 56 millimeters, which is almost doubled than the average drainage level in Shanghai.

Expo site

4 drainage systems and storage tanks of Mengzi, Hou Tan, Puming and South terminals were built in Pudong, Puxi City, with an area of 6.46 square kilometers.

The maximum drainage capacity of the park reaches 56 millimeters per hour, exceeding that of Lujiazui and the Bund.

Purification after rainwater collection

And traditional

drainage system

Different from the "rain and sewage diversion" system designed by the urban construction and Design Institute, the collected dirty rainwater is stored in the super large capacity rainwater storage tank at the underground of the park, and then sent to a special sewage treatment plant for deep purification before discharging into the river.

At the same time, the rainwater pump station also has a dry flow sewage interception pump. When it does not rain, the waste water flowing into the rainwater outlet will be collected and washed into the sewage treatment plant and discharged again.

According to Li Jianquan, deputy chief engineer in charge of drainage system of the Expo site, the rainwater storage tank that meets the international advanced standards in the park is just like an ecological gate. The average interception of pollutants can reach more than 50%, which will significantly improve the water quality of the Huangpu River.

In addition, as one of the eight famous Jingjing in Shanghai, Bailian Jing has 1 km or so coastline across the Pudong Expo site.

Experts through sewage interception, sludge dredging and other measures to thoroughly clean Bailian River bed sludge, effective prevention of rainstorm season in the river water.

Today, Bailian Jing has become a scene of Expo Park.
