Embodiment
With reference to accompanying drawing, specific embodiment of the invention scheme will be described 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; rule of thumb can determine stop time subsequently; use water pump that supernatant liquor is carried out extraction external memory, and the flocculation dirt of tank base, then adopt the mode of hands off to carry out outer row and closedown.
As shown in Figure 2, a specific embodiment of sewage flocculation drainage of the present invention.Itself and prior art, the difference of sewage flocculation drainage is as shown in Figure 1, present invention uses two-stage water quality monitoring (WQM), namely center processor is respectively to the supernatant liquor water quality monitoring (WQM) adding the mixed sewage quality monitoring of flocculation agent and stir after flocculation, achieve flocculation agent addition and the control of flocculation stirring speed adjustment, also use center processor to carry out cycle emissions control to flocculation dirt.Be with another distinguishing characteristics of existing system, present invention uses the throw out collection structure of double-deck umbrella shape cover body as shown in Figure 3 and settler combinations, throw out can be realized be separated smoothly with supernatant liquor, improve supernatant liquor quality, and accelerate the stable collection of throw out.
In Fig. 3, sewage and flocculation agent incoming line 1 are connected by Y-shaped magnetic valve, in Y-valve body exit, turbidity and chromaticity detector I 10 are installed, center processor, by the unlatching size of water quality monitoring (WQM) signal feedback adjustable Y-shaped valve body flocculation agent ingress electromagnetism butterfly valve, realizes flocculation agent addition and controls.Water leg 5 and overflow groove 6 junction are provided with magnetic valve, have installed joint-detection instrument 11 in water leg, and joint-detection instrument 11 comprises suspended substance detector, CODcr detector, turbidity and chromaticity detector II; 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 system in Fig. 3 uses twin-stage stirrer 4 to accelerate sewage flocculation mixing, spiral umbrella cover body I 7 is embedding to be connected on stirrer turning axle, be positioned at above blade of stirrer, 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 at immediately below blade of stirrer, this cover body blade rotation direction is contrary with spiral umbrella cover body I 7 blade rotation direction, spiral umbrella cover body II 8 is mainly used in collecting the flocculation dirt of sinking, prevents dirt to be again taken up in pot liquid whipping process; Settling vessel 9 is installed in immediately below spiral umbrella cover body II 8, in settling vessel 9 structure, top is the blade of spiral tetragon or circular cross-section, this blade is contrary with spiral umbrella cover body II 8 blade rotation direction, settling vessel sidepiece is closed guard structure, this also can guarantee that dirt is collected by again stable, is circular open, with rows of openings size match outer bottom tank body 2 bottom settling vessel.In Fig. 3, tank body 2 bottom is provided with the dirt-collecting cylinder 12 of two ends with magnetic valve, controlled by the center processor in Fig. 2, the flocculation dirt collected by settling vessel can be drained in surge drum by regularly outer, this surge drum volume is the several times that settling vessel structure contains dirt volume, and the volume of dirt-collecting cylinder is received volume with the dirt of the centrigugal swing dryer 13 of below and can be mated, utilize the dirt of dirt-collecting cylinder stored in fade function, the present invention just to achieve in sewage treatment process being separated of flocculation and these two main process of blowdown, the automatic control function of center processor is utilized conveniently to carry out flocculation quality adjustment, and the emissions time regularly controls.
