Description
The present invention provides an initial excellent treatment apparatus capable of preventing clogging of a treatment apparatus by separating and treating contaminants, sedimentary substances, oils, greases and suspended solids in the initial excellent effluent containing high concentration of pollutants in roads and industrial complexes. To provide.
In particular, the present invention is the initial contaminants and sediment contained in the initial excellent effluent flows into the interior of the cylindrical screen, and the remaining contaminants are treated with a filter screen to initially treat the solids and contaminants at the same time To provide a stormwater treatment device.
In general, the sewage discharge method can be largely divided into a confluence type, a classification type and a partial classification type, and a combined discharge method is mainly used in Korea.
The combined discharge method refers to a method in which rainwater flows into sewage pipes during rain and discharges along with the sewage.In rain, rainwater discharges to sewage treatment plants through rainwater segregators installed in sewage pipes, When a large amount is inflowed, a certain amount of sewage and rainwater are discharged to the sewage treatment plant, and the rest is discharged to the stream, lake or ocean directly by overflowing the rainwater soil.
As such, the outflow water flowing out of stormwater is called Combined Sewer Overflows (CSOs) (hereinafter referred to as 'Walkwater'). Since a large amount of these are contained, which can cause pollution such as rivers, lakes or the sea, their control is inevitably emerging.
According to the prior art related to the present invention Patent No. 10-0649180 "initial excellent (non-point source) and sewage pipe overflow water treatment device using the slope plate precipitation" (notice date: November 24, 2006), the upper and lower opening A baffle drum (2) connected in a tangential direction to the inflow pipe (3) communicating with a conduit on one side in a cylindrical tube shape, and a cylindrical screen (4) having a lattice structure and extending to a lower portion of the baffle drum (2); , An inclined plate portion 5 formed by stacking a plurality of inclined plates having an inclination angle so as to surround the outside of the
However, in the conventional early rainwater and sewage overflow water treatment system, the contaminants contained in the overflow water introduced into the baffle drum are attached to the wall surface of the screen so that the contaminants do not fall off naturally even when the water level in the treatment device is lowered. Accordingly, there is a problem that the through-holes of the screen are blocked so that the performance of the screen cannot be properly exhibited, and thus the cleaning should be periodically performed.
In addition, in order to remove the impurities accumulated in the sediment bucket, there was an inconvenience in that the manhole cover was opened to lift the bucket or sucked into the waste disposal vehicle to remove it.
An object of the present invention is to treat the contaminants, sediment, oil, grease and suspended solids in the initial excellent effluent containing high concentrations of pollutants in roads and industrial complexes, and to prevent the blockage of the treatment device. To provide a device.
Another object of the present invention is to treat the contaminants and sediment contained in the initial excellent effluent flow into the cylindrical screen, and the remaining contaminants can be treated with a filter screen to treat solids and contaminants at the same time. An early excellent treatment device is provided.
The initial excellent treatment apparatus according to the present invention receives the rainwater from the rainwater pipe end and receives the rainwater from the first treatment tank and the rainwater treated from the first treatment tank to collect the solids contained in the initial rainwater by the rotational action and included in the rainwater. A second treatment tank for treating the contaminated material with a filter and an intermediate connecting pipe for providing rainwater treated in the first treatment tank to the second treatment tank,
The first treatment tank is a housing having an upper opening, a first body having a first inlet and a first outlet formed on a side wall, and a circular vortex forming unit which forms a vortex in the rainwater introduced into the first body. A cylindrical screen including a through-hole extending vertically to one side of the vortex forming unit and discharging water while filtering the impurities contained in the rainwater, an inlet groove formed on one side of the vortex forming unit, and an inlet and a cylindrical screen of the first body. It is connected to the inlet groove and includes a first connecting pipe for introducing the rainwater in the end of the rain pipe to the inside of the cylindrical screen,
The second treatment tank is a housing having an upper opening, and a second body having a second inlet and a second outlet coupled to a sidewall, and a rainwater flowing into the second inlet through the second body, thereby removing foreign substances. It characterized in that it comprises a filter screen.
Preferably, the cylindrical screen is characterized in that the vortex forming portion and the through hole are formed alternately with each other and formed in a plurality of longitudinal cylindrical shape.
Preferably, the bottom surface of the first body is formed with a cylindrical first support, characterized in that the cylindrical screen is installed on the first support.
Preferably, the first support portion is characterized in that formed in a position spaced at a certain height from the bottom of the first body.
Preferably, the cylindrical screen is characterized in that the trappings are further formed on the inner bottom.
Preferably, the inner upper portion of the cylindrical screen is characterized in that the oil removal portion is further formed.
Preferably, the filter-type screen is connected to the filter support formed in a cylindrical shape, the filter inserted into the filter support, the discharge groove and the discharge groove formed on one side of the filter support portion to the second outlet of the second body to the inside of the filter support. Characterized in that the second connection pipe for discharging the sewage to the second outlet of the second body.
Preferably, the bottom of the second body is formed with a cylindrical second support formed, characterized in that the filter screen is installed on the second support.
Preferably, the filter support is characterized in that formed with a plurality of support grooves to replace the filters.
The initial rainwater treatment apparatus having the contaminant manure cylindrical screen of the present invention can filter the contaminants contained in them while minimizing the influence on the initial rainwater, the overflow water or the sewage flow, and the water can be discharged to the outside. .
In addition, the present invention has the advantage that it is possible to prevent the water discharge portion of the screen to be blocked by placing the contaminants to be filtered to the cylindrical screen in the inner center of the screen.
In addition, since the cylindrical screen can be detachably installed, there is no need for a separate device for cleaning, and accordingly, there is an advantage in that the effort and cost for maintenance of the initial excellent treatment device and the like can be reduced.
