Fieldtrip 2014 : Haikkou (South of China)

Over 4 days, the EnvIM 2014 class toured several water treatment facilities, as well as students attended the two-day Fifth Suez Environment / Tsinghua University Environmental Resources Conference.

Workshop on industrial ecology

Presentation of EnvIM's workshop on industrial ecology, Beijing, December 2014.

After their presentation on the workshop on industrial ecology, in December 2014 (see the article on the workshop), students of the Specialized Master EnvIM visited Haikou (Hainan province) and Shanghai. Their primary purpose was to glean the monumental achievements by China in literally cleaning up their act. Over the last decades, China has demonstrated a strong tenacity in tackling the wastewater issues.

Visit of water treatment sites

he first two days in Haikou were mainly arranged by the Litree company, which is well known in China, and produces UF membrane and UF equipment. For the first morning, students visited two drinking water treatment sites in Haikou. They use UF as the main treatment technology to provide safe drinking water to people in the surrounding area. The first of this sites was the drinking water treatment plant in Beipaishan village(Chengmai county). This drinking water treatment plant provides drinking water for 1,400 people in 3 villages : Beipaishan, Tiantang and Jiashengtang.

Before using UF, the water contained a high turbidity and could turn the bottles black when heated. In June 2012, Litree set up a UF system with a capacity of 200t/d to supply safe drinking water. Water from the well is directly treated by UF and stored in a water tower before transportation to users. The effluent can meet the latest drinking water sanitary standard (BG5749-2006) for the villages. The project can be operated automatically and monitored from long distance, greatly reducing the daily operation difficulties. The project ensures the people get access to safe and cheap drinking water.

The second site was Jinjiang drinking water treatment plant in Chengmai County. Jinjuinag drinking water treatment plant provides drinking water for 70,000 people living in the Chengmai County and nearby villages. The source water comes from the Nandujiang River, but contains bacteria, virus, and turbidity severely exceeding safe water standards before using UF. The project was set up based on the original treatment process: source water-coagulation-leaning pipe precipitation-adjusting tank-UF system-clean water tank-users. The effluent water can meet the drinking water sanitary standard with a turbidity of 0.02 NTU (the GB standard requirement is <1NTU) and no total plate count or collibacillus is detected.

The students also visited Hainan bio CNG, a new energy demonstration project. This project is a highlight of the bio-energy cooperation agreement signed between the Ministry of Science and Technology of PRC (People Republic of China) and Swedish energy agency in 2008. It is also a key project under the new energy construction and energy efficient and emission reduction program included in Hainan’s “Twelfth five-year plan”. The project is designed to develop a public transport system covering the entire Hainan island with buses and taxis fuel by bioCNG generated from local organic wastes. Under the project, 20 biogas plants will be built involving a total investment of RMB 3 billion with a capacity of 200 million bioCNG Nm3/year. The students visited one of these plants, which has currently a production capacity of 6,000 m3/day with a future objective of 30,000 m3/day. The project will gradually help to build a mature industrial cluster of new energy and eco-friendly organic fertilizer production allowing the recycling of organic wastes from farming cultivation and municipal garbage. The potential market for Chinese biogas development is large. According to the estimates, the annual biogas production will reach 200 to 250 billion cubic meters.

Both biogas and natural gas consist mainly of methane. Biogas is produced from the decomposition of organic material that is already in circulation in the biosphere above the earth’s crust, whereas natural gas originates from a similar anaerobic conversion of organic material that took place millions of years ago and from which the resulting gas is buried deep down in fossil layers.

Two days in Shanghai

On Thursday the 11st of December, the students were invited to participate in The Fifth Suez Environment / Tsinghua University Environmental Resources Conference. This year, it took place in Shanghai. Several directors were present, such as the CEO of SUEZ ENVIRONNEMENT Asia, the CEO of SITA WASTE Hong Kong. The conference mainly aimed to present the different partnerships between the Sino-French companies and Tsinghua University.

Then, on December 12th, EnvIM students visited Shanghai Chemical Industrial Park (SCIP). This Eco Industrial Park lies on the north coast of Hangzhou Bay with the total planning area of 29.4km2. It is one of the industrial projects with the highest investment in China during the 10th Five Year Plan period. It is the first industrial zone specialized in the development of petrochemical and fine chemistry businesses since the Opening and Reform Policy. It is built with advanced conception of World-class and large-scale chemical parks and integrated concept. It provides investors in the park with the best investment environment by combining production projects, public utilities, logistics, environmental protection and administration services, with the objective of clean productions and circular economy developements.

While China still has many hurdles to leap, their current trajectory is one to be marveled at, as well as inspire pronounced hope for a cleaner future in one of the world’s global economy pillars.
