SEDIMENT TREATMENT SYSTEM OF SEWAGE AND DIRTY WATER TREATMENT PLANT

摘要

Grit treatment systems for sewage and waste water treatment plants of the present invention is one that contains a mixture of sediment entering the dirt consist of at least the inlet hopper (10), the inlet hopper as to separate the dirt from flowing in the needle thread (10) are installed in a predetermined distance to the axis of rotation and engaging groove (22a) is formed with a plurality of disks in the edge 22 that the screen 20, the disk of the screen (20, 22) for separating a plurality of the disc inserted between the soil (26) consisting of a rotary separator (25), consists of soil below the screen 20 This separated the needle thread as the temporary storage and cleaning primarily installed on top of the first washing tank 30, the first washing tank 30 to the image lights hahyeop shape washing water spraying unit for spraying washing water ( 40), the first washing first conveyance screw for conveying the sediment deposited on the bottom of the tank 30 (50), as a large amount of feed to wash the sediment and secondarily by the first conveyance screw 50 Second washing tank sediment discharge pipe 61 is formed to clean the needle thread (60), the washing water is injected and discharges the washing water in the second washing tank 60, guide portion 70, the second cleaning tank is installed on the inside of 60 impeller to stir the cleaning water (81) and that for driving the agitator impeller 81, and the second conveying screw 90 is vertically installed at the tip of the needle thread discharge tube (60) includes. ; The invention of the sewage treatment system and sewage treatment plant of sediment to be able to recycle the high quality of the sediment by washing the sediment washed twice, so the effect is excellent completely remove the odor and the processing power of the mass It has produced an affordable price.
