Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, the utility model comprises flocculation reaction district 1, settling region 2, bottom, flocculation reaction district 1 is connected with bottom, settling region 2, bottom flocculation reaction district 1, mud valve 3 is equipped with bottom settling region 2, top, settling region 2 is connected with water collecting dike 4, water collecting dike 4 is by water seal 5, syphon trap 6 is connected to strainer 7 feed-water end, strainer 7 water side is connected to filter tank 9 by rising pipe 8, strainer 7 feed-water end is provided with the first valve 71, second valve 72, strainer 7 water side is provided with the 3rd valve 73, first valve 71 is located on syphon trap 6, second valve 72 is connected with water shoot 74, and the level height of the second valve 72 is lower than rising pipe 8, 3rd valve 73 is located on rising pipe 8, liquidometer 41 is provided with in water collecting dike 4, first valve 71, second valve 72, 3rd valve 73, liquidometer 41 is all electrically connected with Controlling System 10.
When implementing the utility model, former water is promoted to top, flocculation reaction district 1 by gravity flow or lift pump, from inflow settling region, bottom 2 after flocculation reaction, flow in water collecting dike 4 through top, settling region 2 again, after flocculation sediment, remove the most suspended substances in former water, be the former water of low turbidity in water collecting dike 4, water collecting dike 4 is connected to strainer 7 by water seal 5, syphon trap 6, and after filtration after process, rising pipe 8 goes out clear water to filter tank 9.Strainer 7 is connected to owing to adopting water seal 5 and syphon trap 6, intake by water seal and instead of the distribution reservoir of valveless filtering pool, water seal water-in is arranged on the water collecting dike 4 at top, settling region 2, and settling region 2 and filter tank 9 can splits, so just can reduce filter tank height, be reduced to about 3.5m from 6.4m.Water seal 5 filtration simultaneously in addition, improves effluent quality, is also provided with back-purge system, improves effluent quality further at strainer 7.
During normal water outlet, the second valve 72 is closed, and the first valve 71 and the 3rd valve 73 are opened.Strainer 7 is producing the initial stage of water to filter tank 9, former water is identical at the liquid level of feed-water end with the liquid level of clear water zone in strainer 7, along with filter continue carry out, the suspended substance retained in filter material layer and adsorb can increase gradually, the resistance of media filtration also can increase thereupon gradually, filtration velocity will reduce simultaneously gradually, and the static pressure liquid level of former water in feed-water end also can rise gradually, also about comes larger with the liquid level difference of clear water zone.Along with continuing to increase of filter material layer resistance, filtering velocity continues to reduce, and the liquid level of water collecting dike 4 also rises gradually, during to design water level, illustrate that the resistance of filter material layer reaches maximum permission resistance, if filter rapid and produce water, after filter, the turbidity of water is by defective, needs filter rinsed 7, now liquidometer 41 sends a signal to Controlling System 10, control the first valve 71 to close, the second valve 72 and the 3rd valve 73 are opened, and enter the back flushing stage.
The level height of the second valve 72 is lower than rising pipe 8, water shoot 74 is lower than the clear water zone flood level in filter tank 9, clear water under gravity in filter tank 9 enters filter material layer from rising pipe 8, because the backwash water entered in filter material layer has certain kinetic energy, filter material layer can be made to produce to the opposite direction of filtering and to expand and disturbance.In the process, the mutual frictional impact of filtrate, make originally to retain and the suspended substance be adsorbed in filter material layer just spins off from filter material layer, muddy water district is entered in the lump with filtrate under the effect of backwash water, in muddy water district, because the proportion of filtrate is larger than suspended substance, filtrate can drop in filter material layer again, and again entering the backwash process of expansion and disturbance, suspended substance then enters water shoot 74 with backwash water and discharges.
As improvement of the present utility model, Controlling System 10 is provided with time control unit, and after backwash process terminates, control the second valve 72 and close, the first valve 71 and the 3rd valve 73 are opened, again normal water outlet, and backwashing time is set to 5 ~ 6 minutes usually.
As improvement of the present utility model, water collecting dike 4 is set to multiple separate unit, and each collection of units mill weir 4 is equipped with water seal 5, syphon trap 6, strainer 7, rising pipe 8, first valve 71, second valve 72, the 3rd valve 73, liquidometer 41.When the strainer 7 of one of them unit enters back flushing operation, the normal water outlet of other unit, can improve water outlet efficiency.
As improvement of the present utility model, in the middle part of settling region 2, be provided with inclined tube 21, after adopting inclined tube to fill, liquid level load can be made from 9m3/m
2.h 30m is brought up to
3/ m
2.h.According to water su pply specification, the liquid level load maximum occurrences of upwelling settling tank is at 9m3/m
2.h, that is 100m is processed
3the water yield of/h, the desilting area of needs is according to specification value, and minimum is 100/9=11.1m
2, and the utility model liquid level load can reach 30m
3/ m
2.h, namely 100m is processed
3the water yield of/h only needs 100/30=3.33m
2, greatly reduce floor space.
As improvement of the present utility model, dividing plate 11 and flap 12 is provided with in the middle part of flocculation reaction district 1, flap 12 forms S shape passage, preferably be set to multiple S shape passage, make the flow direction of former water in flocculation reaction district 1 be upper and lower baffling, and make full use of the gravity flow velocity of current, make to form numerous Turbulence Mixed chalaza between the flap of current in each lattice and lattice, thus make the flocculation agent and the abundant hybrid reaction of former water that are added to flocculation zone, form the good flocculating effect of moderate alumina blossom particles.
