Embodiment 1

[0030] An automatic flap-type water filtration purifier for farmland drainage ditch, which is applied to a farmland drainage ditch with a width of 77cm×height 60cm. The technical solution of the present invention: an automatic flap-type water filtration purifier for farmland drainage ditch, its structure Including infiltration box 1, filter box fixing groove 2, filter wall support frame 3, counterweight 4, support pier 5, support spring 6, rotating shaft 7, support frame fixing groove 8, cleaning material 9, fixing buckle 10; Among them, the counterweight 4 is placed at the bottom of the filter wall support frame 3, and the infiltration box 1 is stacked on the top of the counterweight 4 in the filter box fixing groove 2 according to the requirements, and the infiltration box 1 is placed with the decontamination material 9 The filter wall supporting frame 3 is installed in the fixed groove 8 of the supporting pier 5, connected with the rotating shaft 7 inside, and can rotate alo...

Embodiment 2

[0041] An automatic flap-type water infiltration purifier for farmland drainage ditches. Its structure, size, assembly method and automatic opening and closing conditions of the infiltration wall are the same as those in Embodiment 1, and will not be repeated here.

[0042] Described decontamination material 9 selects the photocatalytic decontamination carrier of loading anatase type nano-TiO for use, and the carrier is that diameter is 0.8cm porous glass ball, and its preparation method is as follows:

[0043] 1) Preparation of anatase TiO by sol-gel method 2 The sol was stirred under the stirring condition of a magnetic stirrer with a rotating speed of 1000 rpm, and the isopropanol solution of the precursor n-butyl titanate was added dropwise at a speed of 120 drops / minute into the dilute nitric acid aqueous solution with a pH of 2.5, and the nitric acid and titanic acid The molar ratios of n-butyl esters were 76:1.42, stirred at 75°C (300 rpm), and refluxed for 24 hours to ...

Abstract

The structure of an automatic plate flipping type water percolation purifier for a farmland drainage ditch, provided by the invention, comprises percolation boxes, a percolation box fixing tank, a percolation wall support frame, a balancing weight, support piers, a support spring, a rotating shaft, support frame fixing grooves, a sewage purifying material and fixing buckles, wherein the balancingweight is inserted into the percolation box fixing tank and is placed at the bottom of the percolation wall support frame, the plurality of percolation boxes are stacked above the balancing weight inthe percolation box fixing tank as required, and the sewage purifying material is arranged in every percolation box; the percolation wall support frame is arranged in the fixing grooves of the supportpiers and are connected by the rotating shaft, and the percolation wall support frame can rotate along the rotating shaft; and the support piers are connected with the percolation wall support framethrough the support ring.

Description

technical field [0001] The invention relates to an automatic flap type water quality percolation purifier for farmland drainage ditches, which belongs to the technical field of farmland non-point source pollution control. Background technique [0002] In recent years, with the growth of population, the development of agricultural technology and the transformation of agricultural production mode, the amount of pesticide spraying and fertilizer application in farmland has increased significantly; the problem of agricultural non-point source pollution caused by excessive application of pesticides and fertilizers is very prominent . Pollutants such as nitrogen, phosphorus, and pesticides in farmland enter other water environments through farmland drainage ditches along with farmland water recede and rainfall after irrigation; farmland drainage ditches are important transportation channels for pollutants, and water purification in drainage ditches is important. The key link to b...
