A salute to nature, the “Guiyang Gravel Contact Oxidation Plant” will soon go into operation.

A corner of “gravel contact oxidation facilities of Guiyang”In the past few years the Taipei City Government has adopted multiple approaches to meet various environmental needs and satisfy the requirements for sustainable development in the city’s treatment of wastewater. One natural and more environment friendly way is to use the “gravel contact oxidation” method to purify wastewater. After water is purified it can then be reused to water vegetation and in water-based landscaping. Successful examples of such an approach have been carried out in Chengmei and Nanhu Gravel contact Oxidation.


The “gravel contact oxidation” method is easy to carry out, and the costs of construction and treatment are lower than traditional wastewater processing plants. Thus this has become the main supplementary support program in city’s wastewater treatment. This is also very meaningful in environmental education and sustainable management, as it is the natural way to handle wastewater.


The “Guiyang Gravel Contact Oxidation Plant” is designed to process 10,000 cubic meters of water using bio-membranes to absorb and degrade organic pollutants and purify the water. The estimated reduction of polluting factors such as bio-chemical oxygen demand, ammonia nitrogen and suspended solids is more than 75%, and it will also effectively improve the water quality of the water body of the Tamsui River upstream of Chonghsiao Bridge. The primary phase of the project was completed on November 25, 2010, and trial operation is now under way. An achievement inspection will be carried out at the end of 2011, and if the trial is successful, formal operation will be initiated.


After the Guiyang Gravel Contact Oxidation Plant goes into operation, an Upper Landscape Park will connect to the Riverside Park to provide the public a place for bird watching, water-related activities and recreational space. The facility will also feature an underground observation corridor to offer teaching outside school for nearby schools, allowing students to observe closely how wastewater is processed and presenting a useful and profound lesson in environmental protection.
