Wastewater denitrification project of a company limited by shares

時間：2017-02-08

The photovoltaic wastewater generated in the production process of monocrystalline silicon and polycrystalline silicon of a company has a wastewater TN of up to 1000 mg/L. In view of the characteristics of wastewater, the company designed and adopted the Anbang denitrification process, with a treatment scale of 2500 t/d and a system effluent TN<40 mg/L, which can stably reach the standard of the sewage treatment plant. The Anbang system covers an area of only 60 m2 and its volumetric efficiency is dozens of times that of the traditional denitrification process.
