Embodiment
As depicted in figs. 1 and 2, integrative water purifying device of the present invention mainly comprises tube mixer 1, mechanical stirring pond 2, flocculation basin 3, side flow lamella 4, adjusting canal 5, molten gas canal 6, charcoal sand filter 7 and the braiding channel 8 connecting successively.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, by dosing mouth 19, in tube mixer 1, adds coagulating agent.In mechanical stirring pond 2, be provided with agitator 9, between mechanical stirring pond 2 and flocculation basin 3, be provided with water distribution wall 10, both are communicated with by water distribution wall 10.Between flocculation basin 3 and side flow lamella 4, be provided with choked flow wall 11, 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 I shape, and its upper and lower is equipped with breach, so that.Machinery flocculation basin 2 and lateral flow tube settler 4 are communicated with in bottom, can reduce the impact to mechanical flocculation basin 2 pool walls into water, the bottom surface of lateral flow tube settler 4 is domatic, be certain slope, slope aspect machinery flocculation basin 2, therefore mud can be back to flocculation basin 2 voluntarily, can prevent the interior formation mud of lateral flow tube settler 4 dead angle area 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 in side flow lamella 12 is horizontal by 60 °.Side flow lamella 4 is connected with regulating canal 5, and the top of adjusting canal 5 is provided with strains hydrophone 14, regulates canal 5 to be connected by straining hydrophone 14 with molten gas canal 6, in molten gas canal 6, is provided with dissolved air release 15.Molten gas canal 6 is connected with the top of charcoal sand filter 7, and the water body in molten gas canal 6 enters charcoal sand filter 7 by the mode of overflow, can prevent that drop from causing breaking of bubble.As shown in Figure 4, in charcoal sand filter 7, be disposed with from bottom to top dissolved air release 15, gac filtering layer 16, quartz sand filtering layer 17 and back flushing water shoot 24.The interior filling carbon leaching material of gac filtering layer 16, the in-built quartz sand filter media of filling out of quartz sand filtering layer 17.Carbon leaching material is brought into play filtration, absorption and biological action simultaneously; First quartz sand filter media can serve as supporting layer, in order to avoid breeze leakage, 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 can effectively guarantees effluent quality.Finally, the uneven surface of quartz sand filter media also can provide for the existence of microorganism the good condition of adhering to, and plays certain biological degradation.On the water surface, there is air supporting process in charcoal sand filter 7, in underwater, occur to filter and adsorption process, and be the integrated of conventional processing and advanced treatment, can save investment and working cost.
Water enters charcoal sand filter 7 by molten gas canal 6 overflows, Filtration Adsorption effect through 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 strains hydrophone, and the water being collected is strained hydrophone by this and discharged by rising pipe 12.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 hydrophone of straining in braiding channel.
Agitator 9 adopts perpendicular axis type, utilizes agitator drive motor to stir water.2, mechanical stirring pond arranges lattice, and in these lattice, flow velocity gradient G changes, according to stirring rake Board position, large near the velocity gradient g value that stirs paddle board place, from stir paddle board more away from velocity gradient g value less.In mechanical stirring pond 2, flow rate of water flow reduces gradually along journey,
g valuealso along journey, reduce gradually, be conducive to form large and closely knit alumen ustum.
Inclined-plate clarifying basin 4 adopts lateral flow, and with respect to anisotropic flow, in precipitation process, mudflow and water (flow) direction are in 90 °, contribute to the downslide of mud; With respect to concurrent, can solve well mud-water separation problem, clear water can be effectively stable is collected in and 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, mixes with water inlet.Sludge reflux can promote clarification, and the throw out that the alumina blossom particles in mud is a kind of sorbent material, the suspended substance in can planar water and reaction generate, makes it separated with water.Meanwhile, the throw out that reaction generates plays again crystallization nuclei effect, impels heavy polymers to grow up gradually, accelerates settlement separate.
Former water enters in tube mixer 1 by water inlet pipe 18, by dosing mouth 19, in tube mixer 1, add coagulating agent, through tube mixer 1, fully mix, first enter mechanical stirring pond 2, by agitator 9, stir and form alumen ustum, enter flocculation basin 3 and flocculate, then pass through side flow lamella 4, impurity particle is sunken to inclined-plate clarifying basin 4 bottoms 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 adjusting canal 5, regulates the water in canal 5 to enter molten gas canal 6 by straining hydrophone 14, and then water molten gas in molten gas canal 6 enter charcoal sand filter 7, and scum silica frost floats on the water surface of charcoal sand filter 7.Air supporting is in molten gas canal 6, to discharge microbubble by dissolved air release 15, and after drainage enters, microbubble adheres on flco, thereby 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.
In the time of need to carrying out backwash to gac filtering layer 16 and quartz sand filtering layer 17, first by blow-down pipe 22 by the water emptying in charcoal 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 charcoal sand filter 7 by back flushing water inlet pipe 23, gac filtering layer 16 and quartz sand filtering layer 17 are carried out to backwash, and backwash water is discharged by back flushing water shoot 24.
