Detailed Description

As shown in fig. 1 and 3, a filter equipment that interception farmland ditch nitrogen phosphorus runs off, include along the fixed location rail 2 that sets up of 1 cross section girth in ditch, with location rail 2 adaptation connection's dismantled plugboard 3, can dismantle the high ditch 1 horizontal plane in upper end of plugboard 3, can dismantle plugboard 3 lower extreme be equipped with location rail 2 from top to bottom the constant head tank 5 of pegging graft, window 4 has been seted up to the lower part of dismantling plugboard 3, the window 4 internal fixation has grid net 6, be close to rivers upper reaches one side at dismantling plugboard 3 and be equipped with salvage frame 7, be close to rivers low reaches one side at dismantling plugboard 3 and be equipped with filtration frame 8. As shown in fig. 3 and 4, two side surfaces of the detachable plug board 3 are provided with guide rail grooves 10 along the longitudinal direction for being respectively plugged with plug pieces 11 arranged on the fishing frame 7 and the filtering frame 8 in a vertically sliding manner. The filter frame 8 is internally provided with a replaceable filler column 9, wherein the filler column 9 is composed of rice hulls or straws wrapped by gauze. The nitrogen and phosphorus adsorption by crops has good effect and is economic and environment-friendly. As shown in fig. 1-4, the height of the fishing frame 7 is higher than the height of the grid mesh 6. The flowing water of the ditch 1 can be ensured to be adsorbed by the filler column 9, so that the adsorption treatment of nitrogen and phosphorus is achieved. As shown in fig. 1 and 2, a first handle 12, a second handle 13 and a third handle 14 are respectively arranged at the top of the detachable plugboard 3, the top of the fishing frame 7 and the top of the filter frame 8. The fishing frame 7, the filtering frame 8 or the detachable plugboard 3 can be lifted conveniently according to the requirement. As shown in fig. 3, the side surface of the upper part of the detachable plug board 3 is provided with a liquid level graduated scale 15, which is convenient for checking the height of the water level in the ditch 1.
