Description

Rectangle Aerated Grit and FOG Remover System [

The present invention relates to a rectangular aeration and oil removal system,

It is possible to concentrate the oil simultaneously with the removal of the needle,

And more particularly, to a rectangular aeration and oil removal system in which a desalination oil removal system can be smoothly operated.

Recently, due to social changes such as dietary habits, a large amount of oil has been introduced into the sewage flowing into the sewage treatment plant,

This oil causes many problems such as blocking the ultra - fine screen of the front part of MBR, which is recently applied to the sewage treatment process.

However, in the conventional gypsum of the sewage treatment plant, a round or rectangular type desolvation removing device capable of separating and removing only the sediments contained in the sewage was installed,

In order to process the oil, there has been a need to separately install an oil processor equipped with various types of oil skimmer through a lot of installation operation costs.

Particularly, in the conventional rectangular type deslagging device, a bucket retracting lifter is installed to separate and discharge the sediment from the raw water,

Since the bucket lifting machine has a complicated structure that collects the settled sediment from the bottom with metal chain and flight and discharges it out of the sedimentation bucket with a needle barrel,

There was a lot of maintenance and maintenance,

In addition, in the event of heavy rain, a large amount of sand was introduced, and the equipment was often buried.

There is no means for separating the organic matter separately from the sedimented sand, and there is a deficiency that includes a hygienic problem such as a bad odor due to the decay of the sand and the discharged organic matter.

An ejector switching valve 22 is attached to the needle discharge ejector 13 and the oil discharge ejector 21,

An ejector pump (23) is connected at one end to the bottom of the treated water tank (24)

And the other side end portion is connected to an oil concentration type silt washing machine 25.

The oil concentration type silb cleanser 25 is provided with a feed hopper 27 and the silt and oil are mixed with the induction water through the needle discharge ejector 13 and the oil discharge ejector 21, However,

A concentrated oil discharge pipe 28 is connected to the upper portion of the charging hopper 27 and an oil separation separator 29 is provided at a lower portion of the charging hopper 27. A discharge hopper 33 connected to the treatment water discharge pipe 31 is connected to the upper portion And a desiccant settling chamber 35 equipped with a desiccant desiccant discharge pipe 37 is attached to the lower end of the apparatus.

In the rectangular aeration and oil removing system of the present invention configured as described above,

When the raw water containing the needle and the oil flows in the longitudinal direction of the rectangular gathering paper 7,

The air discharged from the blower 11 is aerated along the bottom inclined surface of the gutter 7 through the nozzle 9 and the organic matter attached to the gravel is removed by the kinetic energy of the aerated air bubbles, On the other hand,

The sediments separated from the organic material are submerged by the gravity to the bottom of the tiller 7,

At this time, the settled silt is transferred to the side of the silt conveying conveyor 14 located at the center of the bottom of the silt gathers 7, and stored in the silt hopper 12 by the transfer conveyor 14.

The raw water flowing into the gutter 7 is separated by the hopper 19 by the scrapers of the oil skimmer 17 while the water level is kept constant by the swirl baffle 5, do.

The separated and stored sediment and oil fractions are selectively discharged through the operation of the ejector switching valve 22 according to a preset program according to the amount of sedimentation and the amount of oil in the site of the gypsum 7,

The needle thread stored in the needle hopper 12 is connected to the needle thread ejection pump 23 and the needle thread ejection ejector 13 by the system operation of the ejector switching valve 22, In the blocked state,

The water is sucked by the sucker discharge ejector 13 by the induction water discharged from the ejector pump 23 for discharging the oil wollaston, and is discharged to the oil concentration type siltwasher 25.

The oil stored in the oil storage hopper 19 is connected to the oil ejection pump 21 and the oil ejection pump 23 in accordance with the system operation of the ejector switching valve 22, With the connection blocked,

The oil is discharged to the oil concentration type sludge cleaner 25 by the oil discharge ejector 21 by the induction water discharged from the oil sludge discharge ejector pump 23.

The sediment is precipitated into the sedimentation chamber (35) by a specific gravity and then discharged to the dehydrating needle discharge pipe (37) in a state of being dehydrated through the needle washing and discharging screw conveyor (39).

The oil is continuously accumulated in the upper portion of the feed hopper 27 in a state where the oil is prevented from being discharged by the oil separation separator plate 29 of the discharge hopper 33. After a predetermined time has elapsed in the continuously accumulated oil layer, the valve of the concentrated oil discharge pipe 28 is opened to discharge the concentrated oil to the outside,

The treated water in which both the needle and the oil are separated and removed is finally discharged to the outside through the treated water discharge pipe (31).

Therefore, according to the rectangular aeration and oil removing system of the present invention,

It is possible to simultaneously remove and remove the oil together with the needle thread without adding any additional oil removing means to the conventional rectangular type deslagging removing device,

The organic matter adhered to the silkworm flowing into the silkworm 7 is desorbed by the organic matter desorption aeration nozzle 9 so that the organic matter discharged together with the sand is not corrupted and the odor is not generated,

The sedimented sand is separated and collected by a conveying conveyor (14), so that it is free from malfunction and easy to maintain. Even if a large amount of sand is introduced due to heavy rain, it is buried,

The separated sludge and oil can be selectively discharged through the operation of the ejector switching valve 22 according to a preset program in accordance with the settling amount and the oil content of the geyser site,

The oil-enriched nip wash cleaning means is provided to clean and dehydrate the separated and discharged nippers, concentrate the oil, and separate and discharge the nibs under optimal conditions.
