Sewage treatment system suitable for urban rivers

Abstract

The invention belongs to the field of environmental protection, and discloses a sewage treatment system suitable for urban riverways, which comprises a preliminary filtration section, a flotation matter treatment section, a precipitation filtration section and an aeration section which are sequentially arranged in a riverway, and adopts physical filtration, chemical filtration and oxygenolysis toperform sewage interception treatment on the riverway. According to the invention, only is the water environment of the urban riverway not damaged, but also the treated water becomes high-quality landscape water.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to a sewage treatment system suitable for urban rivers. Background technique [0002] With the development of urban scale and economy and society, urban rivers are polluted to varying degrees, including various plastic products and wastewater from various industrial factories. The damaged river will also emit stench, which not only affects people's living environment, but also affects people's health; however, the traditional treatment method is only to clean up the floating objects on the river, and simply filter the water itself. Industrial factories have secretly discharged wastewater that does not meet the standards. Therefore, in the face of water sources with mixed components, simple filtration cannot make beneficial aquatic organisms survive. It is also because of the complex components that it cannot become high-quality landscape water. Contents of the invention ...

[0002] With the development of urban scale and economy and society, urban rivers are polluted to varying degrees, including various plastic products and wastewater from various industrial factories. The damaged river will also emit stench, which not only affects people's living environment, but also affects people's health; however, the traditional treatment method is only to clean up the floating objects on the river, and to simply filter the water itself. Industrial factories have illegally discharged wastewater that does not meet the standards. Therefore, in the face of water sources with mixed components, simple filtration cannot make beneficial aquatic organisms survive. It is also because of the complex components that it cannot become high-quality landscape water.
