High phosphorus content polluted river water treatment method

Abstract

The invention relates to a high phosphorus content polluted river water treatment method and relates to the technical field of river water phosphorus removal. According to the high phosphorus contentpolluted river water treatment method, a riverway soil layer and a bottom frame are specifically utilized, a liquid preparation barrel is arranged above the riverway soil layer, a motor frame is welded to the edge of the upper end of the liquid preparation barrel, a motor is arranged in the motor frame, one end of a transmission shaft is connected to the lower part of the motor, the other end of the transmission shaft is connected with a rotating rod, one end of a through liquid pipe is arranged on an inner wall of the liquid preparation barrel, and a fixed screw penetrates through the insideof the bottom frame. The high phosphorus content polluted river water treatment method disclosed by the invention has the beneficial effects that five liquid discharging pipelines are arranged, so that the liquid discharging pipelines can simultaneously perform high-efficiency phosphorus removal on five areas of river water, and a phosphorus removal agent can be conveniently diffused in the riverwater; thus, the speed of the device for removing excessive phosphorus elements in the river water is improved; the device is provided with a concentration detector, so that the concentration of the phosphorus removal agent can be detected in real time, high-concentration phosphorus removal agents are prevented from being directly injected into river water, and the situation that river water quality becomes bad is avoided.

Description

technical field [0001] The invention relates to the technical field of phosphorus removal from river water, in particular to a treatment method for polluted river water with high phosphorus content. Background technique [0002] River landscape is not only a common landscape form, but also an important ecological corridor and recreational resource, which is of high value in environmental protection and tourism development. However, due to the variability of river landscape, river landscape There are many characteristics and difficulties in protection. Modern people think about the protection of river landscapes from the aspects of nature understanding, regional coordination, tourism mode, ecological water supply, river landscape, shoreline control, system innovation, etc. The history of human use of rivers, It is also a history of transforming the natural landscape of rivers. The variability of rivers makes the task of protecting river landscapes more difficult, especially t...

[0002] River landscape is not only a common landscape form, but also an important ecological corridor and recreational resource, which is of high value in environmental protection and tourism development. However, due to the variability of river landscape, river landscape Protection has its own characteristics and difficulties. Modern people think about the protection of river landscapes from the aspects of nature understanding, regional coordination, tourism mode, ecological water supply, river landscape, shoreline control, system innovation, etc. The history of human use of rivers, It is also the history of transforming the natural landscape of the river. The variability of the river makes the task of protecting the river landscape more difficult, especially the problem of water pollution is not optimistic.

[0003] Existing river water phosphorus removal methods have certain defects. The phosphorus removal agent injected into the river water cannot guarantee its moderate concentration. When a high concentration phosphorus removal agent is injected into the river water, it will destroy the The balance of elements in the river water, followed by the general river water phosphorus removal method is poor in phosphorus removal, and the phosphorus removal agent diffuses slowly in the river water

[0004] A sewage dephosphorization process disclosed in the Chinese invention patent application publication specification CN108640410A, although this kind of sewage dephosphorization process adopts a chemical dephosphorization process, the removal rate is high and the effect is remarkable, but the dephosphorization cost of the device is high, and the dephosphorization Phosphorus range is limited, so large areas of river water cannot be dephosphorized
