1、 Overview

Phosphorus in wastewater mainly exists in the form of free soluble phosphate. When it still fails to meet the discharge standard after general biological and chemical treatment, it is necessary to remove phosphorus in water by chemical phosphorus removal method.

Enhanced phosphorus remover an-120l removes phosphorus through several steps of sedimentation, coagulation, flocculation and separation of sludge and water. The phosphorus removal agent reacts with orthophosphate to form floc precipitation, adsorbs polyphosphate, and polymerizes and flocculates the colloid formed by precipitation with the colloid in wastewater. Finally, it is separated by air flotation, and the removal rate of phosphorus can reach more than 95%, reaching the national emission standard.

Enhanced phosphorus removal agent is a new generation of green phosphorus removal agent further developed on the basis of general phosphorus removal agent. It can achieve the purpose of deep phosphorus removal while coagulation and turbidity removal of urban source water (the total phosphorus of effluent can be controlled within 0.2ppm), so as to reduce the phosphorus content in the treated wastewater below the limit value without changing the raw water treatment process and adding large water treatment structures. It is simple, easy, economical and practical, Remarkable social and economic benefits can be obtained.

four. usage

1. Simulation test

Before normal use, small-scale experiments can be carried out in the laboratory. The methods are as follows:

① Take a certain amount of wastewater to be treated, such as 500ml or 1L (which can be the water of sedimentation tank);

② Measure a certain amount of phosphorus remover an-120l (such as 100ppm / 200ppm / 400ppm, etc.) and add it to the wastewater to be treated;

③ Allow the upper layer of reagent to be fully clarified for about 5 minutes, and then allow the reaction to be layered;

④ Determine the residual phosphorus content in the clear liquid and select the appropriate dosage.

2. Field use:

① Phosphorus removal agent dosing point

The reaction of phosphorus remover is very rapid, and the reaction can be completed within 5 minutes, which can directly treat the wastewater with excessive phosphorus;

Therefore, it can be added in the sand filter or callback tank after the sedimentation tank;

In order to ensure complete reaction, sufficient aeration or stirring is required.

② Optimum dosage

Since the phosphorus content of wastewater (raw water) is different, the dosage will vary according to the level of ammonia nitrogen;

③ The optimal dosage of wastewater is recommended to be determined by experiment and finally adjusted in use.

The optimal dosage can be determined according to the different turbidity of raw water. For general turbid (turbidity in 100-500mg / L) water, 30-50kg of this product can be used per thousand tons. The appropriate dosage can be added for high turbidity industrial sewage of non drinking water.

④ When treating industrial wastewater, dilute the dephosphorization agent to 1-2 times the aqueous solution. When the source water concentration is high and the treated water volume is large, it can be added directly. Then, according to the results of laboratory simulation test, according to the best process conditions and dosage, after full mixing and coagulation sedimentation, the clarified effluent can be obtained.

⑤ The water purification plant can also be diluted 2-5 times and then added.
