Efficient sewage treatment equipment for sewage dephosphorization

Abstract

The invention relates to efficient sewage treatment equipment for sewage dephosphorization. The equipment comprises a main body, a support rod as well as a mixing mechanism and a cleaning mechanism, wherein the mixing mechanism comprises a first driving component, a rotating shaft and at least two rotating plates; the cleaning mechanism comprises a filtering net, a sliding rod, a lifting block, abaffle plate, a scraper plate, a second driving component and two connecting components. According to the efficient sewage treatment equipment for sewage dephosphorization, the rotating plates are driven to rotate by using the mixing mechanism, then sewage can be stirred by using the rotating plates, the sewage can be uniformly mixed with additives, the efficiency that the additives are reacted with phosphate radicals in the sewage can be improved, and the treatment effect of the sewage treatment equipment can be improved; by using the cleaning mechanism, phosphate generated from reactions canbe filtered, meanwhile, the phosphate can be cleaned off from the sewage treatment equipment, the probability that the sewage treatment equipment is blocked is reduced, and the practicability of thesewage treatment equipment can be improved.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a high-efficiency sewage treatment equipment for phosphorus removal from sewage. Background technique [0002] Nowadays, the eutrophication of water body has led to the deterioration of water quality, seriously affecting people's production and life. Nitrogen and phosphorus are important nutrients for aquatic organisms, but algae and other aquatic organisms are more sensitive to phosphorus. To solve the problem of water eutrophication, first To remove phosphorus from sewage, with the advancement of science and the continuous improvement of people's awareness of environmental protection, sustainable development of phosphorus removal technology has become a development trend in the field of wastewater treatment research. [0003] Nowadays, when people treat sewage, most of them use chemical deposition or chemical flocculation. When using the above methods, operators need t...

[0002] Nowadays, the phenomenon of eutrophication in water bodies has led to the deterioration of water quality, seriously affecting people's production and life. Nitrogen and phosphorus are important nutrients for aquatic organisms, but algae and other aquatic organisms are more sensitive to phosphorus. To solve the problem of eutrophication in water bodies, first To remove phosphorus from sewage, with the advancement of science and the continuous improvement of people's awareness of environmental protection, sustainable development of phosphorus removal technology has become a development trend in the field of wastewater treatment research

[0003] Nowadays, when people treat sewage, most of them use chemical deposition or chemical flocculation. When using the above methods, operators need to add calcium salts, iron salts or aluminum salts to the sewage to make the phosphate in the water form insoluble At this time, if the calcium salt, iron salt or aluminum salt added to the water cannot be fully mixed with the water, the reaction efficiency will be reduced, and the effect of phosphorus removal in the sewage will be reduced. Not only that, the phosphoric acid produced by the reaction If the salt cannot be removed from the water in time, phosphate will accumulate inside the sewage treatment equipment, causing blockage of the sewage treatment equipment and reducing the practicability of the sewage treatment equipment
