Classification and Use 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 in sewage, a phosphorus removal agent has been developed independently, which is specialized in the treatment of phosphorus-containing wastewater. It is mainly a brown liquid, which can be used for various aluminum oxidation, chemical polishing, coating, phosphating and other high-phosphorus wastewater. The advantage of the phosphorus removal agent is that it reduces the amount of other phosphorus removal agents and solves the problem of incomplete phosphorus removal., Can save processing costs.
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, since the phosphorus removal agent is added in front of the primary sedimentation tank, the sediment inside it will inevitably be discharged into the primary sedimentation tank. With the gradual increase of phosphorus removal agent, the sludge will also increase greatly, so that many insoluble organic matter in wastewater will be removed, which is not conducive to the subsequent 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
Simultaneous sedimentation dephosphorization is the use of residual sludge in the secondary sedimentation tank to achieve the purpose of phosphorus removal. The dosing position is generally located at the tail of the gas-throwing area of the biochemical reaction tank. 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.
32. Post-precipitation phosphorus removal-put the phosphorus removal agent behind the secondary sedimentation tank (provided that the final sedimentation tank is provided).
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.
