A research and demonstration project to provide technical support for the 169 township sewage treatment plants in the Taihu Lake basin to “upgrade†the standard has recently been fully rolled out in Jiangsu Province. This project, which is specially planned by the government of Jiangsu Province for more than 20 million yuan, aims to tackle 10 phosphorus and nitrogen removal technologies. The results of the toughening completed before the end of June will upgrade existing and new sewage treatment plants. Play a guiding role.
According to requirements of the State and Jiangsu Province for the prevention and control of water pollution in the Taihu Lake Basin, before the end of 2008, Jiangsu Province must complete the complete dephosphorization and denitrification transformation of 139 putative and 30 urban sewage treatment plants under construction in Taihu Lake Basin. 3.6 million tons / day, about 2.7 billion investment. It is reported that all urban sewage treatment plants in the Taihu Lake Basin will implement the most stringent emission standards, and the chemical oxygen demand emission standard limit will be adjusted from 60 to 120 mg/L to 50 to 60 mg/L; the ammonia nitrogen emission standard limit will be 15 mg/L adjusted to 5 mg/L; the TP limit will be adjusted from the original 1 mg/L to 0.5 mg/L.
In order to ensure the economical application of the phosphorus and nitrogen removal transformation technology and equipment, and to complete the “upgrading and upgrading of the sewage treatment plant†within the specified time, the Jiangsu provincial government allocated special funds to carry out the technical research of 10 topics. Considering the sources of nitrogen and phosphorus pollutants in the influent water of urban sewage treatment plants and the follow-up inspection of ecological treatment technologies.
