Abstract

The invention relates to a treatment method of high phosphorus wastewater, which comprises the following steps: at first, adding CaO to adjust the pH of the waste water to be 10.5 to 11.5; then adding 50 to 500 ppm PAC, and stirring for 2 to 5 minutes; finally adding 0.5 to 5 ppm anions, stirring for 10 to 20 minutes, and measuring the phosphorus content. The method has the benefits that the method has the advantages of small project occupied area, good treatment effect, simple operation, no need of secondary sedimentation, no secondary pollution and the like.

Description

technical field [0001] The invention relates to wastewater treatment technology, in particular to a method for treating high-phosphorus wastewater. Background technique [0002] Phosphorus is one of the main elements sustaining life in the earth system, and it is also an essential element that constitutes living organisms and participates in metabolic processes. The abundance of elements and the quality of phosphorus environment will directly affect the growth and development of all organisms including humans; in recent years, the water quality of rivers, lakes, oceans and other waters has deteriorated, especially eutrophication problems have occurred from time to time And it is becoming more and more serious. Eutrophication not only makes the water body lose its proper function, but also makes the ecological environment of the water body evolve in a direction that is not conducive to human beings. Phosphorus is the key nutrient that causes the eutrophication of the water bo...
