“Sludge killing technology” for sewage treatment: the global initiative of Chen Guanghao in the thousand person plan
From 2008 to 2010: in the pilot test stage of treating actual saline sewage at Hong Kong's Tung Chung pump station, Chen Guanghao's team conducted a 225 day continuous and stable on-site pilot test. The sludge yield of Sani process is only 0.64 kg / day, and the sludge reduction is 90%. Compared with the traditional activated sludge process combined with sludge digestion and treatment, Sani process can save energy consumption by 35% and reduce greenhouse gas emissions by 36%.
In 2013, "sludge killing technology" won a joint venture of nearly HK $24.6 million from the Hong Kong Drainage Authority and the innovation and technology fund, carried out large-scale demonstration tests, treated an average of 1000 tons of sewage per day, and effectively reduced sludge production by 70%. In addition, the demonstration plant adopts the high-efficiency coagulation sedimentation technology for the follow-up treatment of the biological treatment unit, which can remove 75% of the total phosphorus in the sewage, and the required volume is only 30% of the traditional sedimentation tank.
In 2014, "mud killing technology" became a technical achievement transformation project vigorously promoted by the Hong Kong SAR government and the Hong Kong University of science and technology.
In recent years, in addition to Hong Kong, "mud killing technology" has also won the support of Cuba, Thailand, the United Arab Emirates and other places, carried out experiments locally, and won the "international haibai Technology Award" of Germany, the "final award of World Smart City Project" of Spain, and many awards of the International Water Association.
Strive to work in Nansha for 1 day every week
This year, Chen Guanghao will allocate more time to the Nansha team. "Strive to work in Nansha for at least one day a week." at present, there are 8 core members of Nansha team. Chen Guanghao will strive to expand the team to more than 30 people in 3 to 5 years to complete the debugging of the mainland version here.
Reasons for choosing to complete mainland version debugging in Nansha
Policy advantage: "one belt, one road is very close to Hongkong, which has a strong radiation effect on the Pearl River Delta, plus the policy advantages that the country has been giving in recent years. This is our ideal headquarters. We are innovating in Hongkong, improving technology in Nansha and taking the track of" one belt and one road "in Nansha.
Chen Guanghao plans that in the next step, he hopes that this team can register the company in Nansha, establish a platform for interaction between industry, University and research officials, and strive to officially put into operation in 2018.
Geographical advantages: as the "mud killing technology" must be combined with seawater resources, the inland coastal water shortage areas have become the first blue ocean market. "Shanghai, Dalian, Xiamen, Qingdao... These 16 coastal cities have a total population of 92 million people. Based on 250 liters of sewage per person per day and 235 grams of dry sludge per meal of sewage treated by the traditional activated sludge process, there are about 2 million tons of dry sludge per year. If the Sani process is applied to these cities, the treatment process of these sludge can be greatly reduced At the same time, 1.2 million tons of carbon dioxide emissions can be reduced every year.
