Online treatment system with particle separation and sedimentation device

Abstract

The invention discloses an online treatment system with a particle separation and sedimentation device. The online treatment system comprises an online treatment tank, wherein a particle separation and sedimentation device is arranged in the online treatment tank and comprises at least two baffle walls, the baffle walls are oppositely arranged at the bottom of the online treatment tank and extendtowards the upper end of the online treatment tank, and a support framework is arranged at the upper ends of the baffle walls; a filter screen is distributed on the support framework to form a semi-closed cavity facing towards one end of the water inlet pipe of the online treatment tank, the semi-closed cavity has an opening and is used for filtering and settling rainwater entering the online treatment tank. According to the online treatment system, the rainwater is pretreated by virtue of the combination of gravity settling and the filter screen, floating objects and greasy dirt in the rainwater are intercepted and are collected into the filter screen, particulate matters in the rainwater are blocked by virtue of the baffle walls and are settled at the bottom of a cavity between the baffles, and finally water flowing out from a water outlet pipe does not contain floating objects, is low in particle content and is relatively clean, so that the pollution of a water body is prevented.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to an online treatment system with a particle separation and sedimentation device. Background technique [0002] With the rapid development of urbanization, the impermeable area on the ground is getting larger and larger, and pollutants are gradually accumulated on these impermeable ground. When it rains, the rainwater washes the ground and the pollutants are washed into the rainwater runoff system to form rainwater runoff pollution. Rainwater runoff pollution is a kind of diffuse pollution, which then enters into natural water bodies, causing water pollution. Non-point source pollution caused by stormwater runoff has gradually become an important source of urban water pollutants. Pollutants in urban stormwater runoff mainly come from wet deposition caused by precipitation leaching atmospheric pollutants and leaching of urban impermeable surface pollutants. , while the ...

AI Technical Summary

Problems solved by technology

At present, most of the rainwater is treated by filter screen, and the rainwater is pre-treated by simple filtration. However, this method of filter screen filtration will bring many problems, such as the filter screen may be blocked, hindering the discharge of rainwater and causing urban waterlogging , the floating objects are not collected after being intercepted, so it is very inconvenient to clean up, and this method is single, it can only remove the floating objects, but cannot remove the particles in the rainwater
