In the present invention, unless otherwise specifically stated or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; the connection can be mechanical connection, electrical connection or communication connection; either directly or indirectly through intervening media, either internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
An industrial sewage purification device for environmental protection engineering comprises a first-stage treatment device, a second-stage treatment device and a third-stage treatment device;
the first-stage treatment device comprises a filter tank, the filter tank comprises a first-stage tank body 1 and a composite filter assembly 2 arranged at the middle end of the first-stage tank body 1, and a first water outlet is formed in the position, below the composite filter assembly 2, of the side wall of the first-stage tank body 1;
the second-stage treatment device comprises a flocculation sedimentation tank 4 and a centrifugal separation tank 6, a second water inlet is arranged on one side of the flocculation sedimentation tank 4, a first communicating pipe 3 is connected between a first water outlet and the second water inlet, a clear liquid outlet is arranged on one side, opposite to the second water inlet, of the flocculation sedimentation tank 4, a clear liquid communicating pipe 5 is connected to the clear liquid outlet, the other end of the clear liquid communicating pipe 5 is erected above the centrifugal separation tank 6, a centrifugal rotary table 7 is connected to the lower portion of the centrifugal separation tank 6, a liquid receiving sleeve 8 is sleeved outside the centrifugal rotary table 7, the side wall of the liquid receiving sleeve 8 extends to a position which is at least 5cm above the top of the centrifugal separation tank 6, and a centrifugal liquid outlet pipe 9 is communicated with the side wall of the liquid receiving sleeve 8;
the third-stage treatment device comprises a chemical treatment tank 10, a centrifugal liquid outlet pipe 9 is communicated with the chemical treatment tank 10, and a purified water outlet pipe 11 is arranged at the top of one side of the chemical treatment tank 10, which is back to the centrifugal liquid outlet pipe 9.
This technical scheme has realized disconnect-type sewage purification, with the secondary separation after the centrifugal separation pond 6 realizes the flocculation and precipitation simultaneously, very big improvement separation purification efficiency, and reduced the use of clean filtration consumptive material, reduced the running cost. The centrifugal separation tank is driven to rotate by the centrifugal turntable 7, solid-liquid separation is realized by the centrifugal force, solid impurities are precipitated at the bottom edge of the centrifugal separation tank 6, and clear liquid flies out from the top edge of the centrifugal separation tank 6 and is caught and collected by the edge of the liquid receiving sleeve 8.
