Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, the high-efficiency sewage purification device comprises a rough filter tank 1, a dosing tank 2, a fine filter tank 3 and a biological aerated filter 4 which are arranged in sequence, wherein adjacent tanks are communicated through a connecting pipeline 5, and a water pump 6 is arranged on the connecting pipeline 5. The middle part in coarse strainer 1 is provided with coarse strainer 7, and coarse strainer 7 slope sets up, and the top below of coarse strainer 7 is provided with flushing pipe 8, and the bottom of coarse strainer 7 is provided with sewage pipes 9, after coarse strainer 1 operation a period, gathers some impurity on the coarse strainer 7, causes the jam to coarse strainer 7, at this moment opens flushing pipe 8, utilizes flushing pipe 8 to wash by water from the below, clears away the impurity on coarse strainer 7 surface to discharge through sewage pipes 9. The water body filtered by the coarse filter tank 1 enters the dosing tank 2.
Be provided with on the dosing tank 2 with medicine mouth 10, be provided with in the dosing tank 2 with pencil 11, pencil 11 and 10 intercommunications with medicine mouth, pencil 11 is the heliciform setting and fixed connection on the inner wall of dosing tank 2, evenly is provided with a plurality of medicine mouths 12 on pencil 11. Through adding medicine mouth 10 to adding the flocculating agent in the pencil 11, the flocculating agent from going out medicine mouth 12 entering dosing tank 2 in, spiral helicine pencil 11 that adds can make the flocculating agent homodisperse in dosing tank 2, makes the flocculating agent can combine and deposit with the suspension rapidly, has improved the efficiency of flocculation and precipitation.
