Selection and Application of Dosing Point of Phosphorus Removal Agent
In order to meet the needs of customers for sewage treatment,Phosphorus removal agent manufacturersIn view of the problem of phosphorus removal from sewage, a professional phosphorus removal agent for the treatment of phosphorus-containing wastewater was independently developed. It is mainly brown liquid, which can be applied to all kinds of aluminum oxidation, chemical polishing, coating, phosphating and other high phosphorus containing wastewater. The advantage of phosphorus removal agent is to reduce the dosage of other phosphorus removal agents, solve the problem of incomplete phosphorus removal, and save the processing cost.
Phosphorus removal agent manufacturersDosing point selection application:
1Pre-precipitation phosphorus removal-put the phosphorus removal agent before the primary sedimentation tank
Phosphorus removal agent manufacturersA large amount of sludge from the primary sedimentation tank is removed to achieve the removal of total phosphorus. However, because the phosphorus removal agent is added to the front of the primary sedimentation tank, the sediment inside will inevitably be arranged in the primary sedimentation tank. With the gradual increase of the dosage of phosphorus removal agent, the sludge will also increase greatly, thus removing a lot of insoluble organic substances in the wastewater. The effect is unfavorable for denitrification and biological phosphorus removal.
2Synchronous precipitation and phosphorus removal-adding phosphorus removal agent to the tail of the aeration zone of the biochemical reaction tank or the end of the oxidation ditch
The method of synchronous sedimentation and phosphorus removal is to remove the remaining sludge from the secondary sedimentation tank. The dosing position is generally located at the tail of the waterfall area of the biochemical reaction tank for dosing. Through coordination with biological phosphorus removal, a large part of total phosphorus can be removed in a process of biological treatment, which can reduce the dosage of phosphorus removal agent, and can help improve the reaction process of phosphate and phosphorus removal agent, greatly improve the efficiency of phosphorus removal, reduce costs, improve the sludge sedimentation performance in the secondary sedimentation tank, and thus increase a concentration of sludge returned.
3Post-precipitation phosphorus removal-put the phosphorus removal agent behind the secondary sedimentation tank(Provided that there is a final sedimentation tank).
Phosphorus removal agent manufacturersThe phosphorus remaining in the wastewater is removed by a series of mixing and flocculation and separation processes. This method of adding phosphorus removal agent requires a coagulation reaction tank and a final sedimentation tank in the process of phosphorus removal. The wastewater enters the depth filtration treatment system after settling in the final sedimentation tank. One problem is that if there is no final sedimentation tank in the whole phosphorus removal process, it is not suitable to add phosphorus removal agent at this dosing point. To avoid affecting the normal operation of the filtration system behind.
