s4, liquid membrane separation and recovery: when carrying out the last irrigation before paddy field maturity in the paddy field, take off U-shaped pipe 4 from drain pipe 3, irrigate the surface of water to just cross behind the end of buckling of drain pipe 3 in the paddy field, slow irrigation speed slowly irrigates a period, collects discharged water and liquid paraffin 8 at the other end of drain pipe 3, separates the recovery to liquid paraffin 8 at last.

Drainage channel 2 can be linked together with the irrigation canal of irrigating the water intaking, when the rainy day rainfall is too big, unnecessary water can flow into in drainage channel 2 via U-shaped pipe 4 and drain pipe 3, in order to maintain the paddy field in the depth of water at the fit for within range, the water that flows into in drainage channel 2 can flow back in irrigating the canal, so that irrigate the use next time, promote water resource utilization ratio, avoid extravagant, and effectively avoided the too high emergence waterlogging of water level to harm and lead to the rice root system to rot, simultaneously, because the bottom of U-shaped pipe 4 is the submergence under the surface of water, consequently at the unnecessary rainwater in-process of discharging, the liquid film that liquid paraffin 8 formed is not influenced.

At ordinary times, as the liquid paraffin 8 can cover the water surface to form a layer of liquid film, the direct contact between the water surface and the air is blocked, thereby effectively inhibiting the inter-plant evaporation phenomenon, further avoiding the waste of water resources, improving the utilization rate of irrigation water, realizing the water-saving effect, ensuring that the liquid paraffin 8 can not be absorbed by the rice in the growth process, ensuring that the liquid paraffin 8 can not influence the growth of the rice, however, if a large amount of liquid paraffin 8 permeates into the soil, the air permeability of the soil and the respiration of the rice root system can be affected, further causing soil pollution, so the anti-seepage baffle 7 arranged around the edge of the paddy field can effectively prevent the liquid paraffin 8 from attaching to the ridge 1 and permeating into the ridge 1, meanwhile, the leakage of the irrigation water in the rice field to the ridges 1 can be prevented, so that the seepage loss of the irrigation water is reduced, and the water-saving effect is further improved.

The utility model provides a separation recovery unit for paddy field water conservation method, includes paraffin cylinder 9, and symmetry fixedly connected with a plurality of pillars 10 on the bottom lateral wall of paraffin cylinder 9, the bottom of paraffin cylinder 9 is equipped with separator tube 11, and threaded connection has stopcock 12 on the bottom of separator tube 11, is equipped with floating block 13 in the paraffin cylinder 9, is equipped with stop device on the both ends of floating block 13, and the lateral wall that separator tube 11 is close to floating block 13 one end is the slope setting.

Be equipped with on the end lateral wall of kicking block 13 with 11 assorted dead slots 17 of separator tube, stop device includes that two are the connecting rod 14 that the symmetry set up, two equal fixed connection of connecting rod 14 are on the lateral wall of kicking block 13, the one end internal rotation that kicking block 13 was kept away from to connecting rod 14 is connected with pivot 15, equal fixedly connected with gyro wheel 16 on the both ends of pivot 15, the equal sliding connection of gyro wheel 16 is on paraffin knockout drum 9's inside wall, the sealed 18 of pad 18 of fixedly connected with on the inside wall of dead slot 17, the end lateral wall of sealed 18 is the curved surface setting.

In order to avoid the water cut-off process before the rice is ripe and harvested, the irrigation water is consumed due to the consumption of the growth and absorption of the rice, the liquid paraffin 8 permeates into the soil to affect the air permeability of the soil and further affect the subsequent planting and use of the soil, the liquid paraffin 8 needs to be separated and recovered in the last irrigation process before the water cut-off process so as to be recycled, when the separation and recovery are carried out, the pipe plug 12 is firstly fixed to the bottom end of the separation pipe 11, then the opening of the paraffin separation cylinder 9 is aligned to the water outlet of the water discharge pipe 3, then the U-shaped pipe 4 is taken down, and then the irrigation is started.

When the liquid level is irrigated to a position that the liquid level is about to cross the port at the bent end of the drain pipe 3, the irrigation speed is slowed down to continue irrigating for a period of time, the liquid paraffin 8 and a part of irrigation water are discharged into the paraffin separation cylinder 9 through the drain pipe 3 by virtue of the layering phenomenon of the liquid paraffin 8 and the water, then the paraffin separation cylinder 9 is vertically placed and is kept still for a period of time until the floating block 13 floats to the boundary position of the liquid paraffin 8 and the water, the average density of the floating block 13 is less than that of the water and greater than that of the liquid paraffin 8, so that the floating block can be suspended at the boundary position of the liquid paraffin 8 and the water, finally the pipe plug 12 is unscrewed to discharge the water at the lower layer, during the water discharging process, the floating block 13 moves downwards along with the liquid level of the water until the pipe orifice of the final separation pipe 11 extends into the empty groove 17 and is blocked by the sealing gasket 18, at the moment, at least, is not discharged, thereby completing the separation and recovery of the liquid paraffin 8, and a small part of the remaining water does not affect the reuse of the liquid paraffin 8.
