Accompanying drawing 1 is a structural profile schematic views of the present utility model, accompanying drawing 2 be the A of accompanying drawing 1 to partial view, accompanying drawing 3 be in the accompanying drawing 1 B to partial view.Sequence number in the accompanying drawings is described as: 1, water inlet pipe, 2, flocculation basin, 3, contact chamber, 4, air flotation separating chamber, 5, inclined tube or swash plate, 6, the clear water collection device, 7, shore pipe, 8, ash pit, 9, header, 10, quartz sand filtering layer, 11, the recoil blow-off pipe, 12, rising pipe, 13, regulating weir, 14, the gac filtering layer, 15, the supercharging water pipe, 16, recoil water pipe, 17, the flocculation shore pipe, 18,19, adjustable plate.

Embodiment

Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this multifunctional modular water-purifying apparatus, comprise have water inlet pipe [1] and the flocculation shore pipe [17] flocculation basin [2] and the contact chamber [3] and settling tank and the filtering basin that are connected one with flocculation basin, be connected header [9] at ash pit [8] and the precipitation inclined plate in the pond, shallow lake of the shore pipe [7] of bottom or the bottom of inclined tube [5] of the air flotation separating chamber [4] with regulating weir [13] and top in it by clear water collection device [6], header [9] is communicated with the filtering basin with quartz sand filtering layer [10] and gac filtering layer [14] through the water distributing area of contact chamber opposite side.

For effect that increases back flushing and the utilization ratio that improves gac, on the basis of the foregoing description, can do following enhancing design.Quartz sand filtering layer [10] and gac filtering layer [14] interior arrangement at filtering basin have recoil blow-off pipe [11], have a supercharging water pipe [15] on rising pipe [12], and gac filtering layer [14] interior arrangement has a recoil water pipe [16].

In order to realize multi-functional purpose, on contact chamber [3] and sidewall that settling tank is connected, have adjustable plate [18] and [19].Like this, when adopting the reverse flow precipitation, adjustable plate [18] is closed, adjustable plate [19] is opened, and the water after flocculation was conditioned the bottom that plate [19] blind hole enters into settling tank originally from contact chamber [3] bottom, forms the reverse flow precipitation.When adopting same flow precipitation, adjustable plate [18] is opened, adjustable plate [19] is closed, this moment through the flocculation after water, entered in the contact chamber the accompanying drawing 1 [3] from being conditioned plate [18] blind hole originally, enter the top of settling tank from the top of contact chamber [3] according to normal concurrent (down to the stream) precipitator method, form down to the stream precipitation.
