Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, the alternately double oxygen/aerobic type earthworm vertical current constructed wetland sewage purification system of the utility model comprises vertical current constructed wetland A, the B of two series connection.Vertical current constructed wetland A, B bottom is connected by pod apertures 1.The bottom of vertical current constructed wetland A, B is equipped with water body gathering system 2, and top layer is provided with water distribution system 4.In conjunction with Fig. 2 and Fig. 3, water distribution system 4 comprises the water distribution branch pipe 42 of cloth water conduit tube 41 and a plurality of parallel arrangements, and water distribution branch pipe 42 is connected with cloth water conduit tube 41 respectively.Water distribution branch pipe 42 is the staggered water distributing pore 43 of two rows to having.Water distributing pore 43 to the vertical line of water distribution branch pipe 42 axis and the angle of weight line is 45 degree.Two distances of arranging between water hole are 10cm, with the distance between the adjacent water distributing pore of row, are 10cm.In conjunction with Fig. 4 to Fig. 6, water body gathering system 2 comprises the collection arm 22 of collecting main 21 and a plurality of parallel arrangements, collects arm 22 and is connected with collection main 21 respectively.Collect arm 22 and be provided with staggered prosopyle 23.Distance between two row prosopyles is 10cm, with the distance between the adjacent prosopyle of row, is 10cm.Water shoot 3 is connected with collection arm 21, and water shoot 3 is provided with water port, and water port place is provided with control valve 5.Water shoot 3 is connected with 21 rotations of collection arm, by the rotation to water shoot 3, regulate the height of water port (or can a plurality of water port be set in the different heights place of water shoot 3, each water port place is equipped with control valve, regulates the elevation of water surface of draining by the switch of control valve).
In conjunction with Fig. 7 to Fig. 9, the utility model effluent purification method concrete steps are as follows:
Step 1, vertical current constructed wetland A, the B of two series connection have been built, each constructed wetland bed height is 1m, two artificial swamp A, B are connected by pod apertures 1, water body can freely exchange by pod apertures 1 in two artificial swamps, and the object of pod apertures 1 is that water body is exchanged equably in two artificial swamp A, B.Artificial swamp long-width ratio is 2:1.
Step 2, in constructed wetland bed bottom, place water-outlet body gathering system 2, it consists of effluent collection main 21, collect arm 22 and circular prosopyle 23 parts form.Circular prosopyle 23 is 2 rows respectively on arm, and alternative arrangement, and it forms with artificial wetland water body gathering system.The diameter of prosopyle 23 is 2cm.
Step 3, in constructed wetland bed bottom spread the gravel bed 6 that 15cm is high, gravel diameter 3-5cm then spreads hypothallus 7 on gravel bed 6, highly for 70cm(hypothallus 7 consist of sand with organic matter by 95%, mix with 5%).
Step 4, on artificial swamp hypothallus, place water distribution system 4, it is comprised of cloth water conduit tube 41, water distribution branch pipe 42 and water distributing pore 43 parts.Be embodied as, water distribution branch pipe 42 is connected on cloth water conduit tube 41, and on water distribution branch pipe 42, makes a call to the circular water distributing pore 43 of two rows, water distributing pore 43 is 45 degree with water distribution branch pipe 42 vertical lines, 2 water hole 43 alternative arrangements of arranging, 2 distances of arranging between water hole 43 are respectively 10cm.Its objective is that sewage enters water distribution branch pipe 42 through cloth water conduit tube 41, then pass through water distributing pore 43 uniformly distributings in artificial swamp stromal surface.
Step 5, on effluent collection main 21, connect by the water shoot 3 of rotation altitude mixture control water port height.The water port maximum height of artificial swamp water shoot, lower than matrix top layer 15 cm, its objective is and makes have the matrix of 15 cm height there be not the water surface to flood (lower than 5cm, selecting optimum water level herein) in draining artificial swamp hypothallus.In addition, can pass through rotary rowed water pipe 3, reduce the water level in constructed wetland bed, as when swivel pipe is during horizontal by 0 degree angle, draining Manual moist telluric water directly discharges, and in artificial swamp, does not accumulate.Therefore, rotatable water shoot 3, regulates the water level in artificial swamp.
Step 6, in artificial swamp planting aquatic plants 8, as reed, Canna generalis Bailey, cattail, Scirpus tabernaemontani etc., and add earthworm 9 in artificial swamp.
Step 7, artificial swamp operation method 1, i.e. vertical current constructed wetland A water inlet, vertical current constructed wetland B water outlet (control valve 5 in vertical current constructed wetland A on water shoot 3 is closed, and the control valve 5 in vertical current constructed wetland B on water shoot 3 is opened).Concrete operation scheme is: first sewage is assigned to sewage vertical current constructed wetland A above equably by water distribution system 4, through pod apertures 1, enters vertical current constructed wetland B, then by the water port of rotatable water shoot 3, discharges.In vertical current constructed wetland B, because water port height is lower than matrix top layer 15cm, therefore, in vertical current constructed wetland B, top layer 15cm, is not had by water logging, and by capillary action, top layer 15cm, in moisture state, is applicable to the growth of earthworm very much.And in vertical current constructed wetland A, not waterflooding for a long time of hypothallus, earthworm also can grow.
Step 8, artificial swamp operation method 2, i.e. vertical current constructed wetland B water inlet, vertical current constructed wetland A water outlet (control valve 5 in vertical current constructed wetland B on water shoot 3 is closed, and the control valve 5 in vertical current constructed wetland A on water shoot 3 is opened).Concrete operation scheme is: first sewage is assigned to sewage vertical current constructed wetland B above equably by water distribution system 4, through pod apertures 1, enters vertical current constructed wetland A, then by the water port of rotatable water shoot 3, discharges.In vertical current constructed wetland A, because water port height is lower than matrix top layer 15cm, therefore, in vertical current constructed wetland A, top layer 15cm, is not had by water logging, and by capillary action, top layer 15cm, in moisture state, is applicable to the growth of earthworm very much.And in vertical current constructed wetland B, not waterflooding for a long time of hypothallus, earthworm also can grow.
Step 9, because artificial swamp stops up the top layer mainly betide drowned flow artificial wet land, and organic matter accumulation mainly betides artificial swamp top layer, therefore, alternately water inlet through artificial swamp, earthworm takes food organism and the effect of interting on artificial swamp top layer, to solve the blockage problem of artificial swamp, and alternately hold concurrently oxygen/aerobic of artificial swamp in addition, also nitrated, the denitrification denitrogenation that are conducive to nitrogen, and organic removal.
After step 10, long-play, if stopping up, artificial swamp occurs in artificial swamp middle level (top layer 15cm is following), now, rotatable water shoot 3, reduce water port height, earthworm is moved to lower floor, solve the blockage problem of artificial swamp matrix middle level, lower floor.
