香港科技大學(xué)在沙田污水廠試驗(yàn)硫酸鹽還原自養(yǎng)硝化反硝化SANI工藝
香港科技大學(xué)開始進(jìn)行硫酸鹽還原、自養(yǎng)反硝化硝化集成工藝的示范性試驗(yàn)研究，該工藝被稱為“SANI"工藝。
The Hong Kong University of Science and Technology will start a large-scale test with the Sulphate reduction, Autotrophic denitrification and Nitrification Integrated (SANI) process at Hong Kong's Shatin sewage treatment works. The pilot plant will have a capacity of 1.000 cubic meter per day.
The test is to start in April 2013 and will be conducted in cooperation with the city's Drainage Services Department. The two year upscale test of the SANI process has been funded with 24.6 million HK dollar.
The SANI process has been developed in close cooperation with Delft Technical University and KWR water recycle research institute in The Netherlands.
科技的香港大學(xué)將開始與硫酸鹽還原作用，自養(yǎng)反硝化和硝化集成（SANI）過程中，在香港的沙田污水處理廠大規(guī)模測(cè)試。該試驗(yàn)工廠將有能力為每天1.000立方米。
該測(cè)試是開始於2013年4月，將在全市渠務(wù)署合作進(jìn)行。撒尼過程為期兩年的高級(jí)測(cè)試已經(jīng)投資了2460萬(wàn)港元。
撒尼過程已經(jīng)制定了與代爾夫特理工大學(xué)和荷蘭的密切合作KWR水循環(huán)研究機(jī)構(gòu)。
SANI工藝是與荷蘭Delft大學(xué)以及KWR水循環(huán)研究學(xué)院共同合作開發(fā)的。
First pilot test started in 2004
A team from the Hong Kong University of Science and Technology (HKUST) led by Prof Guanghao Chen of the Department of Civil and Environmental Engineering will conduct the research.
According to Prof Guanghao Chen the SANI process can solve Hong Kong's long-run problem of sewage treatment: "The research on the process started in 2004, followed by a pilot test jointly hosted with the Drainage Services Department at Tung Chung between 2007 and 2010.
從科技的香港大學(xué)（科大）為首的光浩教授陳民事部與環(huán)境工程學(xué)院的一個(gè)小組將進(jìn)行研究。
據(jù)教授光浩陳撒尼過程可以解決香港的長(zhǎng)遠(yuǎn)經(jīng)營(yíng)的污水處理問題：“對(duì)過程的研究開始于2004年，隨后試聯(lián)合主辦的渠務(wù)署在東涌2007年至2010年。
Results showed that this novel technology effectively eliminated 90% of sewage sludge production, reducing the sewage treatment cost by 50 percent and space requirement by over 50 percent, and cutting down greenhouse gas emissions by 35 percent."
SANI工藝可以降低90%污泥產(chǎn)量，運(yùn)行費(fèi)用可以降低50%，占地也是降低50%，降低溫室氣體35%的排放量。
Triple Water Supply System
The development of the SANI process is part of an innovative research programme by the HKUST on the Triple Water Supply system that combines freshwater, seawater flushing and cooling, and water recycling systems for air-conditioning, kitchen and laundry.
The Hong Kong Airport is the first organization in the world to put the triple water supply system into use, resulting in 52% saving of freshwater demand and up to 20 million in electricity bills and of 30 million kilowatt hour, as well as a reduction of 17,000 tonnes of carbon dioxide emissions per annum, an amount tantamount to greenhouse gas emissions by 5,500 private cars.
Flushing with seawater on city scale
Hong Kong is the only city in the world using seawater for flushing on a city scale. Making an extensive use of the system, the Water Supplies Department has delivered savings of 740,000 cubic meters per day of freshwater.
The water saved in Hong Kong exceeded those recycling systems in Australia and Japan, making it one of the most efficient and cost-effective water facilities in the world.
Many awards
The research programme on Hong Kong Triple Water Supply system has received many awards already. The potential of this system using both sea water and waste water has an enormous potential for many other large cities along the Chinese coastline.
On of the awards was the IWA Global project innovation award 2012 handed out at the IWA's biannual global water conference in Busan, Korea in September 2012.

About SANI process
Conventional biological wastewater treatment processes make use of microbes to convert pollutants in water into carbon dioxide in order to clean waste water. Since microbes grow rapidly, conventional processes produce large amounts of microbes which become sludge.
The SANI process technology, uses a Sulphate-reducing bacteria. In combination with water supply plants that use sea water, the SANI process uses sulphate in seawater as the medium to oxidize and eliminate pollutants from the sewage water.
Since the microbe boasts high efficiency and low growth rate, it minimizes sludge production by 90%, hence its naming as SANI process, meaning "sludge-killing" in Chinese.
