Embodiment

As depicted in figs. 1 and 2, integrative water purifying device of the present invention mainly comprise connect successively tube mixer 1, mechanical stirring pond 2, flocculation basin 3, side flow lamella 4, regulate canal 5, molten gas canal 6, Carbon-sand filter 7 and braiding channel 8.Tube mixer 1 one end is connected with water inlet pipe 18, and one end is connected with mechanical stirring pond 2, and tube mixer 1 is provided with dosing mouth 19, adds coagulating agent by dosing mouth 19 in tube mixer 1.Be provided with agitator 9 in mechanical stirring pond 2, be provided with water distribution wall 10 between mechanical stirring pond 2 and flocculation basin 3, both are communicated with by water distribution wall 10.Be provided with choked flow wall 11 between flocculation basin 3 and side flow lamella 4, flocculation basin 3 is communicated with the bottom of inclined-plate clarifying basin 4 by choked flow wall 11, and as shown in Figure 5, choked flow wall 11 is in I shape, and its upper and lower is equipped with breach.Flocculation basin 3 is communicated with in bottom with lateral flow tube settler 4, the impact of intaking to flocculation basin 3 pool wall can be reduced, the bottom surface of lateral flow tube settler 4 is domatic, in certain slope, slope aspect flocculation basin 3, therefore mud can be back to flocculation basin 3 voluntarily, can prevent from forming mud dead angle area in lateral flow tube settler 4 simultaneously.The bottom of side flow lamella 4 is provided with mud-collecting slot 13, and mud-collecting slot 13 is provided with shore pipe 21.As shown in Figure 3, the swash plate 12 in side flow lamella is horizontal by 60 °.Side flow lamella 4 is connected with adjustment canal 5, regulates the top of canal 5 to be provided with water decanter 14, regulates canal 5 to be connected by water decanter 14 with molten gas canal 6, is provided with dissolved air release 15 in molten gas canal 6.Molten gas canal 6 is connected with the top of Carbon-sand filter 7, and the water body in molten gas canal 6 enters Carbon-sand filter 7 by the mode of overflow, and can prevent drops causes breaking of bubble.As shown in Figure 4, dissolved air release 15, quartz sand filtering layer 17, gac filtering layer 16 and back flushing water shoot 24 is disposed with in Carbon-sand filter 7 from bottom to top.Filling carbon leaching material in gac filtering layer 16, quartz sand filtering layer 17 is in-built fills out quartz sand filter media.Carbon leaching material plays filtration, absorption and biological action simultaneously; First quartz sand filter media can serve as supporting layer, in order to avoid breeze is revealed, secondly, in the operational process of gac, due to the biofilm detachment of activated carbon surface growth and the leakage of abiotic particle, affect effluent quality, quartz sand thickness is set and effectively can ensures effluent quality.Finally, the uneven surface of quartz sand filter media also can provide good attachment condition for the existence of microorganism, plays certain biological degradation.There is air supporting process in Carbon-sand filter 7, occur to filter and adsorption process in underwater on the water surface, and what be conventional processing with advanced treatment is integrated, can investment reduction and working cost.

Water enters Carbon-sand filter 7 by the overflow of molten gas canal 6, through the Filtration Adsorption effect of gac filtering layer 16 with quartz sand filtering layer 17, after filtering, water imports in braiding channel 8, and the top of braiding channel 8 is also provided with water decanter, and the water be collected is discharged by rising pipe 12 by this water decanter.The bottom of braiding channel 8 is provided with rising pipe 20 and back flushing water inlet pipe 23, and back flushing water inlet pipe 23 is provided with blow-down pipe 22, and rising pipe 20 is communicated with the water decanter in braiding channel.

Agitator 9 adopts perpendicular axis type, utilizes agitator drive motor to stir water.Mechanical stirring pond 2 only arranges lattice, and in these lattice, flow velocity gradient G is change, according to stirring rake Board position, large near the velocity gradient g value stirring paddle board place, from stirring paddle board more away from velocity gradient g value less.In mechanical stirring pond 2, flow rate of water flow reduces gradually along journey, and G value also reduces gradually along journey, is conducive to forming large and closely knit alumen ustum.

Inclined-plate clarifying basin 4 adopts lateral flow, relative to anisotropic flow, in precipitation process mudflow and water (flow) direction in 90 °, contribute to the downslide of mud; Relative to concurrent, can solve mud-water separation problem well, what clear water can be effectively stable be collected in regulates canal 5, and most of mud is collected in mud-collecting slot 13 and discharged by shore pipe 21, a small amount of sludge reflux to flocculation basin 3, with intaking mixing.Sludge reflux can promote clarification, the alumina blossom particles in mud be a kind of sorbent material, can the throw out that generates of suspended substance in planar water and reaction, make it be separated with water.Meanwhile, the throw out that reaction generates plays again crystallization nuclei effect, impels heavy polymers to grow up gradually, and Accelerated subsidence is separated.

Former water enters in tube mixer 1 by water inlet pipe 18, in tube mixer 1, coagulating agent is added by dosing mouth 19, fully mix through tube mixer 1, first enter mechanical agitated pool 2, stirred by agitator 9 and form alumen ustum, enter flocculation basin 3 and flocculate, then through side flow lamella 4, impurity particle is sunken to bottom inclined-plate clarifying basin 4 and forms mud, and precipitating sludge is mainly collected in mud accumulation area and discharges, and small part is back to mechanical stirring pond 2.Water continues to flow to adjustment canal 5, and regulate the water in canal 5 to enter molten gas canal 6 by water decanter 14, then water molten gas in molten gas canal 6 enter Carbon-sand filter 7, and scum silica frost floats on the water surface of Carbon-sand filter 7.Air supporting in molten gas canal 6, discharges microbubble by dissolved air release 15, and after drainage enters, microbubble adheres on flco, thus realizes the mandatory floating of flco, reaches solid-liquid separation.The pollutents such as suspended solids in water body, lipid, algae are mainly removed in air supporting.Through air supporting, filtration, adsorption treatment, obtain water outlet.

When needing to carry out backwash to gac filtering layer 16 and quartz sand filtering layer 17, first pass through blow-down pipe 22 by the water emptying in Carbon-sand filter 7, and then carry out back flushing.When back flushing is carried out, by the valve open on back flushing water inlet pipe 23 and back flushing water shoot 24, valve closes on blow-down pipe 22, backwashing water enters Carbon-sand filter 7 by back flushing water inlet pipe 23, carry out backwash to gac filtering layer 16 and quartz sand filtering layer 17, backwash water is discharged by back flushing water shoot 24.
