As shown in the figure, artificial swamp of the present invention comprises water inflow control system, wet land filler bed and outlet controlling system.Artificial swamp water inflow control system comprises into water tank 1, traction rope 2, upper rubber dam formula shield 3, water-in controllable register 4, spring assembly 9 and filtering net 10.Wherein, upper rubber dam formula shield by support frame 5, meet elastomeric material 6, opening handle 7 and standing bolt 8 and form.Traction rope 2 is fixed on support frame 5 by standing bolt 8, and traction rope 2 material is high-strength polyethylene fiber rope or corrosion-resistant steel wire rope.Support frame 5 is stainless steel pipe, and composite rubber material 6 adopts high strength synthetic fibre fabric inside and outside coating rubber to make, and is respectively equipped with 2-5 opening handle 7, upper rubber dam formula shield can be opened when upwards lifting handle 7 at the two ends of support frame 5.Filtering net 10 is bolted on the upper end into water tank, filtering net is integrated structure, between filtering net 10, space is that traction rope 2 reels mobile space, water-in controllable register 4 and water outlet controllable register 15 are by being fixed on the sliding channel upper and lower displacement on tank sidewall, 4-8 symmetrical controllable register is provided with in the bottom of water inlet tank 1 and water outlet tank 13, controllable register material adopts stainless steel to make, and the bottom of water outlet tank is provided with water outlet; Be connected with spring assembly 9 in the lower end of water-in controllable register, the restorer of spring can, when system changeover operation scheme, impel water-in controllable register 4 to close downwards.
As shown in the figure, outlet controlling system comprises water outlet tank 13, traction rope 14, water outlet controllable register 15, retaining ring 16 and traction rope stationary installation 17.The lower end of water outlet controllable register 15 is fixed on the sidewall of water outlet tank 13, and its upper end connects traction rope 14.Retaining ring 13 is stainless steel annulus, is fixed on the inner top side of water outlet tank, and for retraining the position of traction rope, when artificial swamp is run with surface low, water outlet controllable register 12 is in closure state.Traction rope stationary installation 17 is arranged on the outer upper end of water outlet tank, can realize reeling of traction rope 14 fixing.
Temperature is 10
omore than C, runs in surface low mode, as shown in Figure 1.Water inlet tank 1 is in closure state, and water-in controllable register 4 closes simultaneously, prevents aqueous reflux in wet land system from entering in water tank 1.Surface low water inlet 16 is crossed upper rubber dam formula shield 3 and via its water distribution effect, enters wet land system.Water body is by physics chemical action, the plant absorption such as matrix adsorption filtration in flow process, and the effect such as the biological degradation of microorganism, by organic pollutant removals such as the nitrogen phosphorus in sewage.Undercurrent water-in 11 is also in closure state, and now, traction rope 14 is through retaining ring 16, by traction rope stationary installation 17 in tension, water outlet adjustable plate 15 closes, and the surface low water outlet 20 after purification flows into water outlet tank 13 from wetland top, then is discharged by water outlet 18.
Embodiment 2:
In the present embodiment, the mode of constructing of wetland is substantially identical with enforcement 1, but operation scheme is different.When pollution load is higher, as water inlet BOD
5load is higher than 50kgBOD
5during/had, system is run in the mode of drowned flow artificial wet land, as shown in Figure 3.Hold both sides opening handle 7, upwards lift, upper rubber dam shield 3 can be opened, now traction rope 2 drives water-in controllable register 4 to open naturally.The artificial swamp of wide 5m, when water inlet control unit width is 1m, calculate with stainless steel support frame, the stainless steel pipe of external diameter 76mm wall thickness 3.5mm, every meter nearly weighs 6kg, needs 20m stainless steel tube, and heavy 120kg, rubber flush coat density presses 1.5g/m
3calculate, heavy 0.02kg, upper rubber dam shield gross weight is about 120kg.
By opening handle 7, upper rubber dam formula shield 3 is opened, sewage falls into into water tank 1 after first being filtered by filtering net 10, and now water-in controllable register 4 is in opened condition, sewage enters wet land system via undercurrent water-in 11, enter in the drop process of tank at sewage, not only increase the energy of system, the effect of moment oxygenation can also be played simultaneously, thus the problem of dissolved oxygen deficiency in alleviation current wetland, improve the processing efficiency of wet land system.Due to current wetland dispose of sewage time, water below matrix, thus has significant insulation effect, and wet land system can be impelled to improve removal efficiency at low temperatures.By regulating traction rope stationary installation 17, tension promotes traction rope 14, and water outlet adjustable plate 15 is opened.Sewage after process enters water outlet tank 13 by undercurrent water outlet 12, then is discharged by water outlet 18.
