Rear-end treatment system based on phosphorus-containing wastewater

Abstract

The rear-end treatment system comprises a water storage mechanism, a decontamination mechanism and a chemical adding mechanism fixed to the upper portion of the decontamination mechanism, the water storage mechanism comprises a sewage tank and a recycling tank fixed to one side of the sewage tank, and the decontamination mechanism comprises a sliding frame movably connected to the upper portion of the sewage tank; one side of the sliding frame is fixedly connected with a water scraping structure; the invention relates to the technical field of wastewater treatment. According to the rear-end treatment system based on the phosphorus-containing wastewater, suspended solids on the surface are blown to one side of a lifting door plate through movement of a sliding frame, a rotating scraper and an air outlet box, then the suspended solids are conveyed into a recycling box, meanwhile, a metal thin pipe is driven to move front and back in a sewage box, and an internal high-pressure agent is sprayed into an inner cavity of the sewage box; and the two operations are synchronously operated, so that the device is more efficient and stable.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a back-end treatment system based on phosphorus-containing wastewater. Background technique [0002] With the continuous development of industry, the amount of waste water per day is also increasing, and the waste water discharged from some industrial production contains phosphorus elements. Therefore, the above substances contained in the waste water need to be treated before they can be discharged into the environment. In this process, it needs to be completed with the help of wastewater treatment equipment. [0003] As attached to the manual figure 1 In the prior art shown, by driving the froth floating on the surface of the wastewater to the edge of the wastewater treatment tank, and then manually picking it up, when it is necessary to add the agent, it can form a multi-point injection of the agent, and there are the following problems in use : [0004] (1) Th...

AI Technical Summary

Problems solved by technology

[0004] (1) The cleaning method for floating froth is poor, and it cannot be adapted to various thicknesses and liquid levels. Finally, it is necessary to manually clean up the froth, and when the drug is injected, only Poor delivery effect on the surface of sewage

[0005] (2) When there is not much floating foam on the surface, there is no good cleaning method
