Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a zero-discharge device for iron phosphate wastewater. Background Art

[0002] The treatment of ferric phosphate wastewater is a complex and important process, mainly because the wastewater contains high concentrations of harmful substances such as ammonia nitrogen, manganese ions, sulfate, magnesium ions and total phosphorus, and has a low pH value. For the treatment of ferric phosphate wastewater, various methods such as physical, chemical and biological methods are mainly used to achieve standard discharge or resource utilization of wastewater.

[0003] In the existing treatment of phosphoric acid wastewater, the corresponding lime milk precipitation reaction is used to remove phosphate and sulfate. When the lime milk is dumped and transported, it is often transported to the wastewater pool through a single pipeline to react with the phosphoric acid wastewater inside the pool. This feeding method not only cannot ensure the full contact between the pool wastewater and the lime milk, thereby affecting the precipitation reaction rate of the wastewater, but also the lime milk inside the pool will produce flocculent precipitation after the reaction, and it is impossible to quickly extract the precipitation and the reaction water to achieve the separation of the flocculent precipitation and the water body, thereby affecting the overall wastewater treatment efficiency of the pool. For this reason, it is necessary to design a new technical solution to solve it. Summary of the invention
