Embodiment
With reference to accompanying drawing, will describe specific embodiment of the invention scheme in detail.
As shown in Figure 1; in the sewage flocculation drainage of prior art; sewage and flocculation agent are input in tank body according to a certain constant proportioning; and stirrer carries out mixed flocculation with a fixing rotating speed to it; can rule of thumb determine subsequently stop time; use water pump that supernatant liquor is extracted to external memory, and the flocculation dirt of tank base adopt the mode of hands off carry out outer row and close.
As shown in Figure 2, sewage flocculation drainage of the present invention specific embodiment.Itself and prior art, the difference of sewage flocculation drainage is as shown in Figure 1, the present invention has used two-stage water quality monitoring (WQM), be that center processor is respectively to adding the mixed sewage quality monitoring of flocculation agent and stirring the supernatant liquor water quality monitoring (WQM) after flocculation, realize flocculation agent addition and the control of flocculation stirring speed adjustment, also used center processor to carry out cycle emission control to flocculation dirt.Be with another distinguishing characteristics of existing system, the present invention has used double-deck umbrella shape cover body as shown in Figure 3 and the throw out collection structure of settling vessel combination, can realize throw out and separate smoothly with supernatant liquor, improve supernatant liquor quality, and accelerate the stable collection of throw out.
In Fig. 3, sewage and flocculation agent importing pipeline 1 connect by Y-shaped magnetic valve, turbidity and chromaticity detector I 10 are installed in Y-valve body exit, center processor, by the unlatching size of water quality monitoring (WQM) signal feedback adjustable Y-shaped valve body flocculation agent ingress electromagnetism butterfly valve, is realized the control of flocculation agent addition.Water leg 5 and overflow groove 6 junctions are provided with magnetic valve, suspended substance detector, CODcr detector, chromaticity detector and turbidity detector II 11 have been installed in water leg, when water quality detection is not up to standard, center processor determines closed electromagnetic valve between two grooves by the feedback of water quality monitoring (WQM) signal, and reopens magnetic valve after regulating stirrer rotating speed qualified in the hope of water quality.As being used twin-stage stirrer 4 to accelerate sewage flocculation, system in Fig. 3 mixes, 7 embeddings of spiral umbrella cover body I are connected on stirrer turning axle, be positioned at blade of stirrer top, this cover body blade section can be tetragon or circular section, umbrella shape cover body rotates with stirrer, and this cover body blade is identical with blade of stirrer rotation direction, and supernatant liquor floats from cover body blade gaps, throw out is sunk by cover body leaf baffle, and downward beveled structure design can realize dirt and accelerate to decline; Spiral umbrella cover body II 8 is fixedly installed in tank body lower part, cover body blade section can be tetragon or circular section, be positioned under blade of stirrer, this cover body blade rotation direction is contrary with spiral umbrella cover body I 7 blade rotation directions, spiral umbrella cover body II 8 is mainly used in collecting the flocculation dirt of sinking, prevents that dirt is again taken up in pot liquid whipping process; Settling vessel 9 be installed in spiral umbrella cover body II 8 under, in settling vessel 9 structures, top is the blade of spiral tetragon or circular cross-section, this blade is contrary with spiral umbrella cover body II 8 blade rotation directions, settling vessel sidepiece is closed guard structure, this also can guarantee that dirt is by stable collection again, and settling vessel bottom is circular open, with rows of openings size match outside tank body 2 bottoms.In Fig. 3, tank body 2 bottoms are provided with the dirt-collecting cylinder 12 of two ends with magnetic valve, by the center processor control in Fig. 2, the flocculation dirt of being collected by settling vessel can drain in surge drum outside regularly, this surge drum volume is the several times that settling vessel structure contains dirt volume, and the volume of dirt-collecting cylinder can mate with the dirt storage volume of the centrigugal swing dryer of below 13, utilize the dirt of dirt-collecting cylinder to deposit fade function in, the present invention has just realized separating of flocculation and blowdown these two main process in sewage treatment process, utilize the automatic control function of the center processor quality adjustment of conveniently flocculating, and the emissions time regularly control.
