To achieve these goals, the utility model by the following technical solutions: a kind of ecoscape wetland administered for saltings saline-alkali water, comprises the isolation tank be located on saltings, and isolation tank edge forms the chimb exceeding saline and alkaline ground; Be formed centrally the gathering ground of plantation floating plant in isolation tank, periphery, gathering ground forms secondary purifying pool, and periphery, secondary purifying pool forms first clean water area; Chimb is evenly equipped with the saline-alkali water import being communicated with first clean water area, is provided with the water outlet being communicated with gathering ground bottom secondary purifying pool, in first clean water area, is provided with the zeolite basket being filled with zeolite; Upwards be provided with the plantation soil layer of stone layer, stone sand bed and breeding earthworm, planting plants in described two level clean water area successively by bottom, plantation soil layer flushes setting with bottom first clean water area, is equipped with the aeration tube connecting aeration pump in stone layer; Directly over plantation soil layer, circle winding one shower, is provided with the clarified water pump connecting shower in gathering ground.The isolation tank that the utility model arranges band chimb can be located in saltings, prevents extraneous saline and alkaline infiltration simultaneously, zeolite in first clean water area and the earthworm planted in soil layer, plant can purify saline-alkali water, and the conveniently replaced zeolite of zeolite basket, plantation soil layer flushes setting with bottom first clean water area, can ensure that all saline-alkali waters all flow into gathering ground after the purification of plantation soil layer, sandstone layer and stone layer possess good water source runner, aeration tube can increase plantation soil layer, stone sand bed and stone layer, the oxygen content of saline-alkali water, be conducive to the growth of microorganism and plant, saline-alkali water in gathering ground can cause in secondary purifying pool by shower and clarified water pump, carry out circulation water purification, strengthen purifying water effect, sufficient irrigation is carried out to plant simultaneously, in addition, the utility model also increases the green coverage in saltings, protects environment, and cost is low, and purifying water effect is good.
Further, described aeration tube comprises the straight tube that connects aeration pump and along the radial equally distributed ring pipe of stone layer, ring pipe is provided with production well, and ring pipe is communicated with straight tube.The aeration tube aeration area of this setting is large, and aeration is effective, aeration evenly, put in place, also can avoid occurring stagnant water in stone layer, prevent growing of unwanted bacteria.
Further, both sides and the bottom of described spray pipe are equipped with posticum, and be arranged with outside spray pipe and the bracing frame of planting soil layer and contacting, this bracing frame comprises the permanent sleeve be sheathed on outside spray pipe and the leg being extended to ground by permanent sleeve.The support effect of the bracing frame of this setting is good, and easy for installation, quick.
Further, be provided with lift pump in described gathering ground, lift pump connects the farmland irrigating tube on ground.Lift pump and farmland irrigating tube are set and conveniently the water in gathering ground can be drawn the irrigation that be used for farmland, realize making full use of of saline-alkali water.
In sum, it is low that the utility model possesses cost, to the good purification of saline-alkali water, can make full use of saline-alkali water, increase the advantages such as the green coverage in saltings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As shown in Figure 1, a kind of ecoscape wetland administered for saltings saline-alkali water, comprises the circular isolation tank be located on saltings, and isolation tank top one encloses the chimb 1 being formed and exceed saline and alkaline ground; Be formed centrally the gathering ground 3 of plantation floating plant in isolation tank, periphery, gathering ground 3 forms secondary purifying pool 4, and periphery, secondary purifying pool 4 forms first clean water area 5.Chimb 1 is evenly equipped with the saline-alkali water import being communicated with first clean water area 5, the each saline-alkali water pipeline of this saline-alkali water inlet communication, the water outlet being communicated with gathering ground 3 is provided with bottom secondary purifying pool 4, the zeolite basket 51 being filled with zeolite is provided with in first clean water area 5, this zeolite basket 51 is made up of stainless (steel) wire, zeolite basket 51 surface-coated corrosion protection coating.Upwards be provided with stone layer 41, stone sand bed 42 and plantation soil layer 43 successively by bottom in described two level clean water area 4, plantation soil layer 43 forms for rotted plant material and mixing with soil, and stone sand bed 42 is mixed by stone and sand, and stone layer is then laid by stone and formed.Plantation soil layer 43 is planted and is implanted with emergent, also cultivation has earthworm simultaneously, and earthworm can keep the ventilation property of soil, prevents soil hardening, is conducive to the growth of plant, and jointly can also purify saline-alkali water with emergent.Plantation soil layer 43 flushes setting with bottom first clean water area 5, this setting can ensure that all saline-alkali waters all pass through the purification of plantation soil layer 43, improve the regulation effect of saline-alkali water, be equipped with the aeration tube 6 connecting aeration pump in stone layer 41, the aeration tube 6 that this position is settled effectively can strengthen the oxygen content in soil and saline-alkali water; Aeration tube 6 comprises some ring pipes that the straight tube of yi word pattern and radius increase successively, and straight tube connects aeration pump, and ring pipe is along the radial equidistantly distribution of stone layer 41, and ring pipe is provided with production well, and ring pipe is communicated with straight tube.
