The present invention is provided with a sediment lifter (4) is installed to continuously lift the sediment deposited sedimentation in the sewage pipe (3), the sediment lifted by the sediment lifter (4) is primarily a contaminant separator (14) Allow it to enter the phase.

In the contaminant separator 14, a sediment inlet 28 is formed at an upper portion of the sediment inlet 28 so that the sediment can be introduced, and the contaminant separator 14 formed of a drum-type screen of the sediment introduced through the sediment inlet 28. The immersion material is installed while the immersion material injecting device 37 consisting of an injecting screw 37a and an inlet pipe 37b for injecting into the crate is rotated by the motor 27 installed on one side. To be able to transfer feed.

The contaminant separator 14 is connected to the chain gear 40 so as to be rotated by the motor 30, and rollers 41 are installed at the lower left and right sides of the drum wheel 42 to support them during rotation.

Several inner screw plates 44 are formed at the inner edge of the screen 38 constituting the contaminant separator 14 to guide the discharged sediment through the contaminant discharge port 23 and the screen 38. The filtered filtrate and separated sediment from the) to be introduced into the sediment dehydrator 16 through the flow adjustment tank 15 is connected to the bottom.

The bypass pipe 26 is connected to the flow rate adjustment tank 15 so that the filtrate and the sediment can be bypassed through the filtrate opening 43 of the sewage pipe 3 in the case of overflow.

The sediment dehydrator 16 is composed of a drum-type screen tube as shown in FIG. 5, and a plurality of sediment filtrate discharge holes 35 are drilled so that the filtrate contained in the sediment is lowered with the dehydration filtrate 25. Through the filtrate connecting port 43 to be discharged to the sewage pipe (3).

And the inside of the immersion dehydrator 16 by installing a screw shaft 33 having a screw blade 34 in the longitudinal direction can be discharged through the immersion dehydrator discharge port 21 of the filtrate dehydrated filtrate In order to increase the dewatering efficiency, by installing a compression plate (36) elastically installed in the spring to be able to compress and dewater the sediment.

The dehydrated sediment discharge conveyor 17 is installed in the lower portion of the sediment dehydrator discharge port 21 to allow the dehydrated sediment to be transferred to the dehydrated sediment storage hopper 18, and the dehydrated sediment. Under the storage hopper 18, the storage hopper gate 24 is connected to the hydraulic cylinder 32 to selectively discharge the dehydrated sediment, so that the sediment can be fermented and composted or buried selectively. It is.

The process of dehydrating the sediment in sewage using the sediment dewatering device for sewage treatment of the present invention which can be configured as described above will be described in more detail below.

When sewage flows through the inflow sewage pipe (1), large contaminants are filtered through the crude wood screen (2), and sewage and sediment in the sewage introduced through the sewage pipe (3) are deposited on the floor. The sediment separator 14 made of a drum-type screen 38 by driving the input screw 37a of the sediment inlet device 37 through the sediment inlet 28 while being lifted while the sediment intake device 4 is continuously driven. The filtrate and fine sediment are dropped and drained into the lower flow adjusting tank 15 in the screen 38 rotated by the motor 30 after being fed into the bed, and the contaminants are separated by the plurality of inner screw partitions 44. It is transported to one side of the waste discharge is collected through the trickle discharge port (23).

The fine sediment and the filtrate dropped and drained into the flow adjusting tank 15 are introduced onto the sediment dehydrator 16 through the sedimentation channel 20 to constitute a drum-shaped tube, and the plurality of sediment filtrate discharge holes 35 are formed. Inside the punched sediment dehydrator 16, the filtrate is drained through the sediment filtrate discharge hole 35 through the lower dehydration filtrate 25 to the sewer pipe (3), and the fine sediment dehydrator ( 16) the compressed material is transported onto the compression plate 36 by a screw shaft 33 having a screw blade 34 installed in the longitudinal direction therein, and the sediment and the filtrate are compressed and dehydrated, and the compression plate 36 When the fine sediment is compressed by the screw blade 34 so as to be elastically installed in the spring to overcome the elasticity of the spring, the compression plate 36 is pushed to the rear side, and the dehydrated sediment is connected to the lower side. After the discharge is made to the outlet 21 is installed inclined After being transported onto the dehydrated sediment storage hopper 18 by the dewatered sediment discharge conveyor 17, the storage hopper gate 24 is selectively opened and closed to ferment the collected stored sediments by the operation of the hydraulic cylinder 32. It can be composted or landfilled.

As described in detail above, in the sewage treatment, various sediments (various contaminants, fine sediments, etc.) accumulated in the inflow sewage pipe 3 are lifted by the sediment lifter 4 to have a 99% water content. The sediments, wood, bottles, etc. are separated and discharged first by the sediment separator 14, and the fine sediments of a predetermined size or less are secondly compressed and dehydrated by the sediment dehydrator 16 and lowered to a moisture content of 75% or less. It can maximize the treatment efficiency of sewage by reducing the quantity of water, eliminating the odor of odor generated from moisture, and separating and dehydrating it continuously even if there is much sediment due to the increase of sewage and waste water.

In addition, it is possible to minimize the maintenance and repair costs of the treatment device by preventing damage to mechanical devices such as the drainage pump 6 due to the inflow of soil, bottles, rocks and the like.

In addition, the sediment collected in the present invention can obtain a good compost when fermented by fermentation to increase the recycling rate of resources, thereby reducing the sewage treatment costs.

For reference, the sediment with 99% water content currently costs about 20,000 won per ton, so if 5㎥ / ton of sediment is generated per day, 1,800 tons are generated per year. It will have a savings of about 36,000,000 won.
