Customer requirements:
The daily discharge of a certain sewage treatment plant is 50000 cubic meters, and the main sources of pollution are urban sewage and industrial wastewater. Its process is FAB filter+denitrification filter. At present, the total nitrogen is relatively high, exceeding 20mg/L, while the emission standard is 15mg/L.
The solutions provided by the company:
The company dispatched technical personnel to conduct on-site inspections and provided a solution for adding water treatment carbon sources. Because the main method of treating sewage in this sewage treatment plant is biochemical treatment, and the core of biochemical treatment is to ensure that bacteria achieve maximum activity, which requires a C: N: P ratio of 100:5:1. However, the ratio of sewage entering a general sewage treatment plant is 80:20:3, which cannot guarantee the rapid growth and reproduction of bacteria and maintain high activity. Therefore, it is necessary to add water treatment carbon sources to achieve this optimal ratio, ensuring the growth and activity of bacteria.
Final effect:
After introducing the company's independently developed small molecule carbon source, the total nitrogen was reduced to below 10mg/L, and the denitrification rate was fast without affecting the effluent COD. The customer is very satisfied with our product, and we have been cooperating for 2 years now.
