Tail water dephosphorization equipment for municipal sewage treatment plant

Abstract

The invention discloses tail water dephosphorization equipment for a municipal sewage treatment plant, which structurally comprises a water inlet pipe, a water collecting tank, a motor, a treatment device, a water spraying tank, a water purifying tank, a blow-off pipe and a purified water outlet pipe, the water inlet pipe is fixedly installed at the left end of the water collecting tank in an embedded mode and communicated with the water collecting tank, and tail water exerts pressure on a swing storage frame; meanwhile, guide spring rods in two guide frames guide and limit the outer side end of a swinging storage frame, phosphorus in the tail water is adsorbed through a filter material placed in the swinging storage frame, it is ensured that the tail water makes comprehensive contact with the filter material, filtered impurities and suspended solids flow downwards to make contact with an opening and closing plate. The telescopic pipe is downwards extruded by the opening and closing plate, impurities and suspended solids are concentrated in the collecting box, adsorption of the impurities and the suspended solids is improved through an adsorption rod and a thin rod, the cleanliness of the filter material mechanism is improved, and it is ensured that phosphorus in tail water is comprehensively adsorbed and removed by the filter material mechanism.

Description

Technical field [0001] The present invention relates to the field of urban sewage treatment and resource technology, in particular, in particular, involving a urban sewage treatment plant tail water in addition to phosphorus. Background technique [0002] Urban sewage refers to urban residents' living sewage, organs, schools, hospitals, commercial services, and various public facilities drainage, and allowed to discharge into urban sewage collection systems, industrial wastewater and initial rain water, etc., after treatment of urban sewage, sewage The tail water contains a large amount of orthophosphate, polyphosphate and organophosphorus, which requires use to remove phosphorus in the tail water in the dephosphorization equipment, but the phosphorus is adsorbed by the phosphorus by phosphorus, by placing inside the filter. The filter material is contacted with tail water, thereby adsorbing phosphorus, and the area of ​​contact with the tail water is limited, and there is a cert...

AI Technical Summary

Problems solved by technology

[0002] Urban sewage refers to the domestic sewage of urban residents, the drainage of government agencies, schools, hospitals, commercial service institutions and various public facilities, as well as the industrial wastewater and initial rainwater that are allowed to be discharged into the urban sewage collection system. After the urban sewage is treated, the sewage The tail water contains a large amount of orthophosphate, polyphosphate and organic phosphorus, and it is necessary to use phosphorus removal equipment to remove phosphorus in the tail water. However, due to the use of physical adsorption in the phosphorus removal equipment to adsorb phosphorus, by placing The filter material is in contact with the tail water to remove phosphorus by adsorption, but the contact area between the filter material and the tail water is limited, and there is a certain amount of suspended matter in the tail water, which is easy to be suspended and adsorbed on the surface layer of the filter material, resulting in It is difficult to fully adsorb phosphorus in the tail water, which reduces the effect of tail water purification
