Description
The present invention relates to a non-point pollution source reduction apparatus, and more particularly, to a non-point pollution source reduction apparatus capable of enhancing a good treatment effect by blocking an obstruction of a filter caused by an effective filter by backwashing.
Generally, pollution sources in urban areas are classified into point pollution sources and nonpoint pollution sources. Among these, nonpoint pollution source is a pollutant that is exposed to the ground surface during rainfall and is used as a source of pollutant to be swept into the sewer pipe.
Especially, when the nonpoint sources included in the initial rainfall are introduced into the public waters, they cause pollution of the rivers and lakes, and they penetrate into the underground and become a factor causing pollution of groundwater resources. Therefore, the pollutants that are introduced together with the initial rainwater must be discharged to the discharge water through purification and purification processes.
Conventional early stormwater treatment apparatuses for treating contaminants introduced along with initial storms can be classified into a variety of initial stormwater treatment apparatuses such as a storage type such as artificial wetlands, a filtration type such as a filtration tank, a device type such as a swirl treatment apparatus These early stormwater treatment devices each have advantages and disadvantages.
Since the storage type requires a large facility area, there is a problem in applying to the urban area. Therefore, the initial quality treatment device applied to the urban area is mainly composed of a swirling method using centrifugal force and a method of processing by filtration And the treatment efficiency of these initial treatments is constant, but it is difficult to expect elastic treatment efficiency for nonpoint source caused by rainfall with large flow rate and concentration change.
In the conventional vortex system, precipitates can be removed, but it is difficult to remove suspended matters. Especially, when the initial storm is introduced due to rainfall, sediments accumulated due to the rain during the re- The water treatment efficiency is lowered.
The filtration method is effective for removing particulate matter as compared with the swirl method, but since it is difficult to precipitate rapidly, the required capacity of the apparatus is large and the existing sediment is re-floated when the initial storm is introduced. Therefore, Is lowered.
Korean Patent Registration No. 10-1300070 discloses a nonpoint pollution abatement facility. The above-described non-point pollution abatement facility has an advantage that the treatment efficiency can be increased by using the precipitation and filtration methods in combination.
However, there is a problem that contaminants desorbed from the filter during backwashing flow into the space where the treatment water is collected, thereby deteriorating the effect of the excellent treatment. Further, there is a problem in that the cleaning effect of the filter is not high in the backwashing method by the air-aeration method.
The present invention has been made in order to solve the above problems, and it is an object of the present invention to prevent the clogging of the filter by the contaminants by effective backwashing and to prevent the contaminants desorbed from the filter from flowing into the space where the treatment water is collected, And to provide a non-point pollution source abatement device capable of enhancing a non-point pollution source.
In order to accomplish the above object, the non-point pollution source reduction apparatus of the present invention comprises: a main body having an inlet port through which rainwater is introduced into a front surface; A partition wall formed in the main body to partition the internal space of the main body into a sedimentation space part and a filtration space part located behind the sedimentation space part; A filtration unit installed in the filtration space to remove contaminants in the stormwater flowing into the filtration space through the partition wall; A discharge unit for discharging the treated water passing through the filtration unit to the outside; Backwash means for backwashing the filtration unit by supplying air to the filtration unit; And a sediment collecting unit connected to the backwashing means for discharging the sediment accumulated on the bottom of the filtration space portion to the outside by using the air supplied from the backwashing means.
Wherein the filtration unit includes a casing having a plurality of water holes formed therein and having a height higher than that of the partition, a perforated plate provided inside the casing to partition the interior of the casing into a first filter portion and a second filter portion, A porous filter member or non-porous filter member filled in the filter unit and a filter member installed in the second filter unit to block contaminants desorbed from the first filter unit during backwashing of the first filter unit from being introduced into the process water A plate-shaped fiber filter is provided.
The backwashing means includes a blower, a main supply pipe connected to the blower and extending to the filtration space, and a second filter installed in the first filter to branch off from the main supply pipe, Organs.
The sediment collecting unit includes a venturi pipe connected to the main supply pipe, a connection pipe connected to the venturi pipe and extending to the outside of the main body, a recovery tank connected to the connection pipe and through which the sediment flows, And a spacer bar formed at a lower portion of the intake-side loudspeaker to separate the intake port of the intake-side loudspeaker from the bottom of the filtration space portion.
And a vibration applying unit for applying vibration to the porous or non-porous filter media during backwashing of the first filter unit.
The vibration imparting means includes a protrusion formed on the front surface of the perforated plate and positioned between the perforated porous media or non-porous media, and a vibration generating unit connected to the perforated plate to reciprocate the perforated plate upward and downward The vibration generating unit includes a housing mounted on the perforated plate, a rotating shaft rotatably installed in the housing and passing through the housing, a cam coupled to the rotating shaft and received in the housing, And a motor for rotating the rotary shaft.
As described above, according to the present invention, it is possible to effectively supply contaminants such as soil and the like adhering to the filter media by strongly supplying air to the filtered filter media during backwashing of the filter, It is possible to block the inflow into the treated water by the fiber filter.
In addition, the backwashing effect can be greatly improved by applying vibration to the filter during backwashing, thereby preventing the filter from being blocked by the contaminant, thereby improving the effect of the good treatment.
