The removal of total phosphorus is a common sewage treatment problem. Industrial wastewater and domestic sewage often contain nitrogen and phosphorus substances, of which organic and inorganic It is the most common component. If the nitrogen and phosphorus substances in the water are not properly treated and discharged into the water body, it will cause serious eutrophication in the water body, causing algae and other plankton to multiply rapidly. Therefore, the government environmental protection department recently denitrified and dephosphorized wastewater Processing requirements are becoming more and more stringent.

The outer wall of the connecting shaft is fixedly connected with a stirring rod. When the liquid in the mixing tube flows, it drives the rotating blade to rotate, which in turn drives the connecting shaft and the stirring rod to rotate. The rotation of the stirring rod can stir the liquid in the mixing tube, so that the waste water and the medicine Liquid mixing is more thorough.

However, the above-mentioned device can only stir and mix in the mixing tube when it is in use, and the flow rate of water is relatively fast in the process of water intake, and cannot effectively stir and mix when flowing through the mixing tube, which will inevitably lead to Inhomogeneous mixing with wastewater occurs, and when the wastewater enters the treatment tank, it cannot stir the wastewater outside the mixing tube, resulting in low efficiency of phosphorus removal from wastewater. In addition, the device needs to be kept in the process of entering the water Adding liquid medicine can not control the amount of liquid medicine, which will lead to excessive investment of liquid medicine, resulting in increased cost and waste of liquid medicine. For this reason, we have proposed a phosphorus removal device for wastewater treatment.
