Jiangsu Offshore Wastewater Removal Phosphorus and Nitrogen Removal Technology

A project that provides technical support for the upgrading of the Taihu Lake Sewage Disposal Plant has recently commenced in full swing.

The content of the project is to solve the problem of phosphorus and nitrogen removal technology, and the government of Jiangsu Province arranges special funds of more than 20 million yuan to support it. The research results completed before the end of June this year will play a guiding role in the lifting of bids for existing wastewater treatment plants and new wastewater treatment plants.

According to the requirements of national and Jiangsu Province Taihu Lake water pollution prevention and control work, by the end of 2008, Jiangsu Province shall implement the dephosphorization and nitrogen removal transformation of 139 putative and 30 urban sewage treatment plants under construction in the Taihu Lake Basin. 3.6 million tons / day, need to invest about 2.7 billion. Because this work is at the forefront of the country, the existing sewage treatment plant is not the same process, its technical route, economic indicators, etc. are not perfect, Jiangsu Provincial Government allocated special funds to carry out 10 research topics. In the framework of the project, the sources of nitrogen and phosphorus pollutants in the influent water of urban wastewater treatment plants and the follow-up inspections of ecological treatment technologies were considered.

As Wuxi City has conducted a large number of experiments on the dephosphorization, denitrification and ecological treatment of sewage, the artificial wetland project is one step ahead. Therefore, of the nine projects that tackled the existing sewage treatment plants, six were obtained from Wuxi. At present, these topics have all entered the opening report stage, and the research results will provide data on multiple schemes and cost and energy consumption for the reconstruction of over 100 wastewater treatment plants in the Taihu Lake Basin in the second half of the year.
