沙田污水處理廠




Have you ever wondered what happens to the water we flush down our toilets and sinks?
I bet you haven’t thought much about it, but sewage treatment is a serious business that is essential to our health and environment. One of the most important sewage treatment plants in Hong Kong is the Sha Tin Sewage Treatment Works. This plant processes over 2 million cubic meters of sewage every day, which is enough to fill 800 Olympic-sized swimming pools!
The process of sewage treatment is actually quite complex, but I’ll try to give you a simplified overview. First, the sewage is screened to remove large objects such as rags and sticks. Then, the sewage is pumped into settling tanks, where the solids settle to the bottom and the liquids flow off the top. The solids are then removed and disposed of, and the liquids are sent to aeration tanks, where they are mixed with oxygen to break down the remaining organic matter.
After the aeration tanks, the sewage is sent to secondary settling tanks, where the remaining solids settle to the bottom and the liquids flow off the top. The solids are then removed and disposed of, and the liquids are disinfected with chlorine to kill any remaining bacteria. The disinfected water is then discharged into Victoria Harbour.
So, there you have it! The next time you flush your toilet, take a moment to think about the journey that your waste will take before it is safely discharged into the environment.
Here are some interesting facts about the Sha Tin Sewage Treatment Works:
  • The plant was built in 1977 and was the first major sewage treatment plant in Hong Kong.
  • The plant is located on a 26-hectare site in Sha Tin, next to the Sha Tin Racecourse.
  • The plant has a staff of over 200 people.
  • The plant is open to the public for tours.
If you are ever in the area, I encourage you to take a tour of the Sha Tin Sewage Treatment Works. It’s a fascinating place to learn about the important role that sewage treatment plays in our lives.
