Problem addressed

Conventional wastewater treatment method cannot remove total nitrogen in coal-fired power plant wastewater effectively, making it difficult to comply with the discharge requirements of local government.

Innovation
  • Discover that the main ingredient of total nitrogen in wastewater comes from Nitrogen-Sulphur (NS) compound, which is difficult to treat with conventional treament method.
  • This novel solution can convert the NS compound into nitrate, thereby removing all nitrogen in the wastewater through advanced biochemical technology.
  • Simple and feasible biochemcial treatment process.
Key impact
  • It is highly cost-effective and can significantly reduce investment and operating costs.
  • Low energy consumption and low carbon emission during treatment process.
  • The total nitrogen contents in pollutant were reduced after treatment, resulting in wastewater that met the stipulated discharge standard.
