This is a consistent pretreatment process that allows for more efficient separation and removal of contaminants and sediments from influents such as water, sewage and wastewater.

In general, water, sewage, and waste water are required to separate and remove various sediments such as sludge and soil and sand contained in the water, sewage and waste water as a pretreatment process in the water treatment process.

To this end, sedimentary lifters and sludge collectors have been proposed for collecting sediment and contaminants in various ways.

In the case of the sediment removal device, since the rectangular long channel was formed and the sediment collected by the horizontal screw conveyor equal to the channel length was lifted by the inclined screw conveyor, a lot of site was required and excessive civil construction cost was incurred. There was a required closure, and there was a burden of separately installing a device for preventing investment due to the inflow of large amounts of soil, so that the structure is complicated, resulting in a significant increase in maintenance costs.

In addition, since these sediment removal devices were dualized with the contaminant collection device, the treatment facilities and processes were complicated, many required sites were required, and the site selection was often limited, which required a lot of water treatment costs. There was a discontinuance.

Still another object of the present invention is to provide a comprehensive pretreatment apparatus such as water, sewage, and wastewater that can separate and collect various contaminants such as sludge together with sediment in water, sewage, and wastewater in a consistent process.

In order to achieve the above object, the present invention,

The influent flowing into the water, sewage and wastewater treatment plant is introduced into the circular sedimentation tank. The centrifugal force by the impeller discharges the supernatant to the aftertreatment device through the discharge channel, and the sediments such as soil or sand are collected at the center. By picking it up by the tornado generated in the tornado block,

It is characterized in that the sediment can be separated and removed more efficiently at a less required site.

In addition, the present invention,

In the intermediate step, the immersion removal device is used as an intermediate step, and the inflow water composed of water, sewage, and waste water is introduced into the micro bar screen, and the contaminants contained in the inflow water are collected and separated by a micro bar screen and compressed into a compression dewatering screw conveyor. On the other hand, the dehydration filtrate is returned to the inflow channel, and the inflow water passing through the micro bar screen portion is separated from the sediment through the sediment removal device, and then, as a later step, the sediment is sucked into the sedimentation cleaning device. By spraying the washing water with high pressure on the sediment, the suspended solids are separated and the collected sand is lifted and collected by the inclined screw conveyor,

It is characterized by the fact that it is possible to separate and remove contaminants and sediments more efficiently from influent such as water, sewage, and wastewater as a consistently pre-processing process.
