Low Carbon Life Begins from You and Me(Fourth)
The expedition activities of urban residents’ activities and air quality joined by Peking University and the University of Hong Kong came to an end on October 20, 2016. There were many destinations in the last day including Shenzhen Bay Park, Baishi Zhou, Dachong Cun, Nanshan Wastewater Treatment plant and Authority of Qianhai Shenzhen-Hongkong Modern Service Industry Cooperation Zone of Shenzhen.

The first trip was Shenzhen Bay Park. Standing in the bike lanes, we can see the Shenzhen Bay Cross Sea Bridge and The Mai Po Wetland park, Hong Kong. Walking towards north is the mangrove forest ecological park, where there are many drains along the way, which can discharge the city sewage into the sea. And we can smell terrible odors sometimes. There are also many rubbish, cockroach in the Shenzhen Bay that need to be governed urgently.

The second trip was urban villages, i.e. Baishi Zhou and Dachong Cun. These two villages were located very close, but had different forms of the city. Baishi Zhou had the largest amount and most concentration of rental housing of Shenzhen City. In contrast, Dachong Cun had become a new modern high-end residential areas after the transformation. The obvious contrast made students think a lot for the issues of urban villages.

The third trip was Nanshan sewage treatment plant. Nanshan sewage treatment plant, at present, is the largest one in Shenzhen, which can treat 735 thousand tons of sewage one day. Our group was warmly received by the plant’s manager. The manager led us to visit all the sewage treatment equipments such as anaerobic tank, biochemical pool, secondary sedimentation tank, ultraviolet disinfection canal, skimmer, dehydrator and so on, and he explained the sewage treatment process in detail. Students listened attentively and raised their worry about how to reduce the increasing drainage pressure in the context of increasing rapid population and fast urban growth. The manager replied that, as for the future development of the plant, the technological innovation would be of uppermost priority instead of simple expansion.

The fourth trip was the exhibition hall of Qianhai. Qianhai is the window of Shenzhen’s opening up, whose development reflects that Shenzhen is in a more open state in the future development. Our group members deeply felt the city’s rapid growth and determined to contribute to the city’s future development.

At this point, the activities of PKU & HKU urban resident activity and air quality joint delegation ended. Throughout the activities, students not only enjoyed the beautiful natural scenery and cultural landscapes in Shenzhen, but also learned its history and witnessed its rapid development. Although only having a short period of four days to get along, the teachers and students of two schools have established a profound friendship and promised to communicate more in the future. We hope that the development of this city could achieve the goal of “low-carbon, environmentally friendly, intensively and high-efficiently”, and we eager to devote ourselves to it.
