Multi-stage rotational flow particle suspended matter discharging device and process thereof

Abstract

The invention provides a multi-stage rotational flow particle suspended matter discharging device and a process thereof, and relates to the technical field of water supply and drainage and environmental protection application, according to the technical scheme, the multi-stage rotational flow particle suspended matter discharging device comprises a plurality of S-shaped rotational flow sedimentation channels which are continuously arranged, each S-shaped rotational flow sedimentation channel is provided with two baffling points which are respectively an upstream baffling point and a downstream baffling point, and the upstream baffling point and the downstream baffling point are communicated with each other. A rotational flow slag collecting tank is arranged at the baffling point, a dense porous isolation plate is arranged at the communicating part of the baffling point and the rotational flow slag collecting tank, and an automatic slag discharging device is arranged in the rotational flow slag collecting tank. The content of suspended particles in the wastewater drainage process can be reduced, and the effects of automatically collecting the suspended particles in water and effectively improving the water quality are achieved.

Description

technical field [0001] The invention relates to the technical fields of water supply and drainage and environmental protection applications, in particular to a multi-stage swirling particle suspension device and a process thereof. Background technique [0002] At present, the river has a large amount of water intake, and the main pollutants in the water are suspended solids (SS). According to environmental management regulations, enterprises should build multi-stage sedimentation tanks and filter tanks, as well as buffer pools to accommodate accidental water. However, during the use of multi-stage sedimentation tanks on the ground, the following problems often occur: (1) Most sedimentation treatment facilities do not have automatic sludge discharge devices, and the existing sludge discharge devices have poor slag discharge effects, and particles accumulate at the bottom of the sedimentation tanks, and the effective volume gradually decreases; (2) The bottom of the pool need...

Problems solved by technology

However, during the use of multi-stage sedimentation tanks on the ground, the following problems often occur: (1) Most sedimentation treatment facilities do not have automatic sludge discharge devices, and the existing sludge discharge devices have poor slag discharge effects, and particles accumulate at the bottom of the sedimentation tanks, and the effective volume gradually decreases; (2) The bottom of the pool needs to be manually dredged every year, which is labor-intensive and is a limited space operation, with high safety risks; (3) During the process of manual dredging of the pool bottom, dredging and deposits cause large fluctuations in water quality, which has a negative impact on subsequent water treatment facilities The impact load is high, which can easily cause environmental events such as excessive discharge of water; (4) The long-term high particulate matter content of discharged sewage causes serious wear and tear on drainage pipes and water pumps, and the frequency of replacement increases; (5) The problem of sedimentation of particulate matter in sedimentation tanks seriously affects the reduction Improve efficiency
