Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a high-nitrogen rectification wastewater treatment device. Background Technique

[0002] The treatment of high-nitrogen rectification wastewater is a complex but crucial process. The main purpose is to reduce the nitrogen content in the wastewater to meet the requirements of environmental protection discharge standards and resource recovery and utilization. In current photovoltaic plants, a large amount of nitrogen-containing wastewater is generated during the production process. In order to reduce the sewage treatment cost and meet the environmental protection requirements, magnesium compounds, phosphoric acid or hydrogen phosphate are added to make NH4﹢ in the wastewater react with Mg﹢ and PO4﹣ to form magnesium ammonium phosphate precipitate to remove ammonia nitrogen. After treatment, the nitrogen content in the wastewater is significantly reduced to meet the environmental protection discharge standards.

[0003] Existing wastewater treatment equipment cannot evenly add substances such as magnesium compounds, phosphoric acid or hydrogen phosphate to ammonia nitrogen wastewater. Under the condition of only using the stirring function, these substances cannot be quickly mixed with ammonia nitrogen wastewater, reducing the reaction rate and being unfavorable for the efficient treatment of wastewater.
